Author of The Origin of Species and creator of the theory of evolution and the concept of natural selection

3,722 Questions

Which one is true the theory of Charles Darwin that man came from the apes or God made man?

The debate of the creation of humanity dates back to when science was just beginning to become a major contender of religion.

According to Christian faith, their deity known as God, created man through Adam and Eve, from which all supposedly descend from. This is supported by entries in the Bible.

The theory of evolution of mankind, proposed by English naturalist, Charles Robert Darwin, suggests that man was not simply created by a deity, but instead evolved as a species from apes in a process known as natural selection. This is supported by the study of how other species and animals evolve and our similarities to apes.

How did Darwin apply Malthus' ideas about human population growth to the theory of evolution by natural selection?

Malthus's idea was that our food production grows at a linear rate, while our population grows logistally. More people are being born than can be fed. Thus this leads competition for survival. Darwin observed that this is true for all organisms. More offsprings are born than can be sustained, thus leading to differential survival of organisms, thus natural selection.

What are current theries that conflict with Darwin's theory what evidence is used to support thses theories?

Current theories that conflict with Darwin's theory of evolution include Lamarckism, which suggests acquired traits can be passed down through generations, and Saltationism, which proposes that large evolutionary changes can happen suddenly. Supporters of Lamarckism cite cases of epigenetics as evidence, while proponents of Saltationism point to instances of punctuated equilibrium in the fossil record to support their claims.

What counter-argument can you use if someone argues that you should not believe in plate tectonics because it is only a theory and theories are just guesses that don't mean much scientifically?

Show them a good dictionary. The scientific meaning is usually the primary meaning given in good dictionaries for the word theory.

Theory is the highest concept in science as it is a explanatory frame work supported by much evidence and tested hypothesis for a phenomenon observed in nature. ( a fact/law ) You can generate testable hypothesis from theories. Theory encompasses law and fact and explains much of law and fact. A theory is falsifiable.

Invention of Charles Darwin?

Charles Darwin is best known for his theory of evolution by natural selection, outlined in his book "On the Origin of Species." His work revolutionized the field of biology by providing a scientific explanation for the diversity of life on Earth, highlighting the role of adaptation and natural selection in driving evolutionary change. Darwin's ideas have had a profound and lasting impact on our understanding of the natural world.

What role does the environment play in Darins theory of evolution by natural selection?

In Darwin's theory of evolution by natural selection, the environment is a key driver of the process. Organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. Environmental pressures, such as competition for resources or changes in climate, drive the process of natural selection by selecting for traits that increase an organism's fitness for survival.

Was Charles Darwin a geologist?

Darwin had a somewhat eclectic education; he started out being trained in medicine, then moved to theology with natural history being a hobby. During his journey on the Beagle he described himself as a geologist; he'd been strongly influenced by Lyell's Principia Geologica and was seeing the world through a geologist's eye. His shipmates called him "Philosopher". Before the publication of The Origin of the Species, Darwin did some research on barnicles - this was partly to establish himself as a "serious" scientist - he was considered an authority on barnicles. After the publication of Origin, he was widely considered a naturalist and has been ever since.

How did Charles Darwin solve the theory of evolution?

Evolution was seen by many. But the mechanics were not well understood. One of Darwin's observations involved finches in the different Galapagos Islands. Each island had finches with slightly different physical attributes. Charles Darwin noticed that the shape of their beaks were different, depending on their primary food. Some beaks were shaped to make eating seeds more efficient. Others were shaped to eat insects.

The finches that Darwin brought back as stuffed specimens, are still present in the British Museum. The collection is mounted, and it is easy to see the differences. Darwin felt that all of these different finches were descendants of finches that were blown on to the islands during a storm. Darwin was able to show that small differences gave finches on various islands an advantage. After many generations, each island had finches whose differences were very obvious.

According to Darwin, the finch that lived on a specific island, did not choose to change. But small changes in beak structure, gave those birds an advantage. They were able to gather more food, and eventually had more living offspring.

A good example are dandelions growing on a lawn. The lawn mower is set at a specific height. As you mow your lawn, the taller dandelions have their tops cut off. No flowers, they can't reproduce. But the few shorter dandelions are left, their pollen reproduce, and now most of the dandelions are short, close to the ground, and difficult for the lawn mower to cut them off.

What was the major proposal in Charles Darwin's On the Origin of the Species?

The major proposal in Charles Darwin's On the Origin of Species is the theory of evolution by natural selection. Darwin proposed that species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring.

Which postulate of natural selection is best supported by the work of Gregor Mendel?

The postulate of variation is best supported by Mendel's work. His experiments with pea plants demonstrated the presence of distinct hereditary traits that can be passed down through generations, providing evidence for the existence of genetic variation within a population.

Do any qualified scientists support the creation theory?

Prior to reading the answers below, it is perhaps important to note that there is no 'creation theory'. There are various religious creation myths, but no comprehensive and robust scientific model that has any explanatory or predictive power.

Answer: Quite a few scientists support creation theory. This places them out of step with the mainstream scientists who believe in autobiogenesis, or a spontaneous origin of life, coupled with evolution. As Richard Dawkins put it "It is a monumental disagreement. One side or the other has got to be wrong, and not just slightly wrong but catastrophically, ignominiously, disastrously wrong."

Prior to the 20th Century, most scientists believed in Creation.

Today, there are numerous organizations of scientists who support creation theory: Answers in Genesis ; Creation Research, Science Education Foundation; Institute for Creation Research; The Creation SuperLibrary and others. Some publish peer-reviewed journals, such as the Creation Research Society's CRS Journal and the Journal of Creation by Creation Ministries International (The Australian arm of Answers in Genesis).

Answer While it is true that many "scientists" disagree with evolution in favor of creationism, that number drops significantly when you consider only those who study nature or life, and is almost non-existent when you consider only those with expertise in fields like biology, paleontology, geology or astronomy - the above list may seem impressive, but it is out of well over a hundred thousand PhD scientists alive today. Now it's also important to note that many scientists believe in some sort of god or creator, but are not creationists. Creationism generally refers to strict 6-day creation fundamentalism or the movement to teach that there is a god in science classes in public schools. About 60% of scientists believe in a personal god, many believe this god created life indirectly, which can be considered a different sort of creationism. Meanwhile about 99.85% of earth and life scientists (those same scientists who mostly believe in a personal god) accept evolution as well.

Answer Yes, quite a few actually. Many scientists and researchers have come to support the creation theory because as they study 'Creation -vs- Evolution' they have found that there are more 'holes' in the evolution theory than there are in 'Creation'.

Both Creationism and Evolution start with presuppositions. Evolution starts with the presupposition that God, if He exists, played no part in the development of species, but that they developed by macro-evolution or chance mutations that resulted in benefit to the organisms; Creationism presumes that He created all species, and that there are minor adaptions which occur naturally, called micro-evolution.

What are the three concepts that make up the cell theory?

This answer on the bottom helped me soooooo much on my Science Homework!!! thanx 1. every living thing is made up of one or more cells. ex. A polar bear is a multicellular organism. 2.cells carry out the functions needed to support life. ex. Fat cells are animal cells that provide energy as well as insulation. 3.cells come only from other living things. ex. Each polar bear cub began as a single cell. hope this helps =]

Is evolution a theory yes or no?

Yes and no.

Evolution is an observed biological phenomenon, and therefore fact.

Evolutionary theory is a model explaining the things we find in biology and paleontology in terms of what we know about evolution through genetics and population dynamics.

The point really is not that evolution can be seen as either as theory or as fact, the point is that it is a factual theory; it is a theory which is so well supported by vast quantities of evidence that it would be unscientific and unreasonable to doubt the validity of that theory. Scientists also do not know everything about the evolutionary history of the Earth, or about exactly how evolution takes place, and research into evolutionary biology continues. Theories can be revised. But in the case of Darwin's Theory of Evolution, although many details have been revised, and additional details are likely to be revised, the essential thesis remains, that life does evolve, and that evolution is the process by which the species we observe today on Earth (including the human race) came into existence. Of that, there is no reasonable doubt. Of course, if anyone has a religious belief which compels them to believe otherwise, that is their privilege, but the pious rejection of science does not lead to a better understanding of reality.

Is evolution a theory?

Yes, by definition evolution is a theory (hence it is called the 'theory of evolution').

Despite what some would try to argue, this is not a statement against evolution's credibility and the concepts involved. Rather, it is a statement of complete and unanimous support by the scientific community, which finds evolution to be the simplest and most logical explanation for the phenomena involved, as well as fitting the evidence, providing predictions which can be tested and passing all tests that ever attempted to break it.

Another answer

It is also a hypothesis, a fact and a process, and none of these are a problem either.

However, as much as some would like to see this as a problem, we must first note what a theory is. In scientific terms, a theory is a hypothesis which has been experimentally confirmed, has made accurate predictions about phenomena, accommodates all known facts about the subject, and is widely accepted as correct.

We must contrast this definition with that often used by those who don't understand it; in that case, a theory would be more correctly referred to by the term hypothesis, which is an explanation of something but which has yet to be experimentally confirmed.

So in basic terms, a theory is an idea which - after a lot of testing and experimentation and criticism and debate - has been determined to fit all the facts, explain those facts consistently, and make reliable predictions.

In short, it's about as close as you can get to certainty. The vast majority of the scientific community - about 99.9% of all qualified scientists - accept it as such. There is no better explanation of how life on earth came to be the way it is now.

Who proposed the theory of evolution?

Charles Darwin wrote a book called On the Origin of Species, in which he explained his conclusions that 1) modern species derived from ancestors they share with other species, and 2) that the driving mechanisms behind this development is reproductive variation and natural selection.

What are arguments against Intelligent Design?

ID can refer to either a pseudo scientific concept, a philosophical argument, or a political/ideological crusade against science and naturalism. I will explain the arguments against each.

The pseudoscientific concept is pseudo scientific because it is not testable empirically, and has no potential to ever be falsified. The scientific method (observe, hypothesize, predict, experiment and invite peer review) cannot and has not been brought to bear on it, but it's supporters want it taught in science textbooks anyway, and are using the political process to bypass the scientific process, making it the very definition of pseudoscience.

The philosophical argument is that life, the universe etc is too complex or too orderly to have arisen by any means other than intelligence. While I myself do not agree with that logic, this is the most respectable and logical form ID takes. The next and last is the sleaziest. The political/ideological movement known as ID is a movement intent on undermining science and naturalism. The organization leading the ID movement in the US, the Discovery Institute, had leaked an internal memo called the Wedge Document (available on the internet, google it and you will find it in about 10 seconds) which they first denied was from their organization, and later admitted to. It laid out their plans to undermine the teaching and public acceptance of evolution based on clear religious motives. They blame scientific naturalism for every bad thing that's happened in the past several centuries and want to open science up to include non-natural explanations, which of course cannot be tested by any scientific means. This last form of ID is particularly awful because it seeks to lie to children (teach them false science) and uses all manner of lies, manipulation and deception to meet it's goals. The leaders of the ID movement routinely lie about their religious motives, lie about the state of scientific acceptance of their arguments, and lie about their true motives. If they wanted to come out and argue that naturalism or science is responsible for this war or that social trend, that would be fine. They would be wrong, and would be shown to be wrong very easily. But at least it would be an honest mistake or an honest opinion, not a dishonest propaganda campaign.

Intelligent design says we were made by something smart. Science says we evolved; Science has no opinion one way or the other as to whether or not something intelligent and supernatural was involved in that evolution. Basically, the reason some people would prefer that ID not be taught in school is because it's religion, and it's a waste of time in a science classroom. If God was involved there's no way to prove or disprove that - so why deal with it in a class solely devoted to things you *can* prove or disprove? Religion's what your parents and church are for, not school. There's a place for ID, but it's not in a science class. Basically scientists are upset that religious people want to say religion is a science when the religious answer is usually "it's a miracle". Nobody will ever learn anything new if the answer is "it's a miracle". Science wants to know why; if the answer is "don't ask questions, that's God's business" that's not really useful, so scientists want to keep the two firmly separated.

Another Answer

I will be anwering their points in order to demonstrate arguments against Intelligent Design, because arguments against ID consistent entirely of deconstructing ID's nonarguments.

Here is their first point: ---- "Any argument against intelligent design would have to demonstrate how information and design, including irreducible complexity, can arise by chance processes." ---- >>>>This sounds very much like someone who has bought the ID sophistry line, hook, and sinker, as even the very first sentence has many things wrong with it. First, 'information' in ID has never been a coherent concept. In fact, in the case of Dembski's attempts to mislead, using definitions of information from information theory shows that specification (which is a reasonable substitution for the responder's 'design') is the antithesis of information. On that same note, irreducible complexity is also a highly misleading term, and one which is quite simply inane. How does 'irreducible complexity' work, you ask? Well, let's just see how the originator (and definer) of the term goes about showing it: take a biochemical process with multiple parts, declare that taking out any part would make the process no longer perform its current function, and then declare that because of this, it could not have evolved. This is a deceptively convincing argument, but there is nothing that forces evolutionary changes to always add parts to a process, which is what one must assume to find Behe's argument a reflection of reality. If we were to take an example at a larger scale than Behe usually concentrates on, we could look at horse's digits, of which four have been lost from their ancestor, which posessed five. However, maybe that's not complex enough for someone convinced by ID's nonsensical ideas, so instead we will take the example of a European Mayfly's front limbs, which are used for mating. Does it really make sense to look at this fact and declare that because of this, the Mayfly could not have arisen through natural evolutionary mechanisms? To use the reasoning of Behe, we'd have to start declaring that four legs cannot support a Mayfly, certainly during the transition (denying contingency). The answerer also used the classic Creationist terminology: it isn't evolutionary explanations that need to be offered, but 'chance processes'. The problem here is that 'chance' can mean various things depending on the context. Many people in this discussion call 'chance' anything that doesn't involve something like a deity. However, there's no need to use that language if that's the case. Instead, it is used to mislead by implying that evolutionary mechanisms are 'random', like static or flipping a coin, when in fact natural selection is constrained by the environment, heredity, contingency, etc, all of which fit nicely under the term 'deterministic'. But I've gone on quite a while on ID's general weaknesses. The more obvious problem, still with the very first sentence, is that it is very likely an argument from ignorance. It's an essential declaration that unless there is an evolutionary explanation for X, there aren't arguments against ID. This at best assumes ID's accuracy and at worst is presented as a cogent argument. Well, that took a while. Hopefully the rest won't be so verbose! ---- "It would probably also need to demonstrate how the genetic code and the 'reading' of that code as well as its repair and replication mechanisms could all arise simultaneously by chance processes."

---- >>>>This should be familiar by now. They're using the creationist rhetoric of 'chance processes' and the assumption of their own accuracy to demand answers from others. If they don't get them, this person thinks ID 'wins' by default because they've entirely skipped the very first problem with ID: none of the arguments for its accuracy are interesting, let alone sound. Many are based on obvious fallacies, some (like Behe's) on pure, arrogant ignorance. So, time for some labels: this one's an argument from ignorance or a denial of the burden of proof. ---- "Any argument against ID would need specifically need to be on a scientific basis, as ID proponents specifically deny any role for religion in their 'movement' which is why most Creation scientists, while appreciating the work done by ID scientists, distance themselves somewhat from them."

---- >>>>Why should the arguments against ID be on a scientific basis when ID itself is not just pseudoscience but illogic? It doesn't take an in-depth familiarity with biology to realize the vacuity of ID, just a little bit of the vocabulary of logic. ID proponents lie. The responder may want to get used to this, because despite denying any role for religion in their 'movement', these pesky things like the Wedge Document and Casey Luskin in general keep popping up. Or 'Of Pandas and People'. Or Dembski's declarations of his motives and how he wraps up ID into his Christianity. ---- "All the arguments used by ID are scientific and scientifically verifiable and so arguments against ID would need to do the same." ---- >>>>The responder would have to demonstrate a single one. However, they can't, because ID simply does not have 'scientifically verifiable' arguments. It has no predictions, in fact in many cases the logic is so vague and twisted that it's entirely untestable even with speculation. I would recommend to readers that reading the 'party line' of ID and the short responses of those defending science is not enough to understand why ID isn't scientifically verifiable. For me, it helped significantly to read about the scientific method and the scientific blogs which argued, quite well, how ID's arguments do not fit the bill. ---- "Just so' stories about a hypothetical primordial soup in which life arose by chance from chemicals, contrary to the scientific law of Biogenesis would not disprove ID anymore than it does Creation." ---- >>>>Now it's very apparent that the poster is likely a creationist unwilling to openly admit their opinion. Even the major ID proponents recognize the difference between abiogenesis and evolutionary theory and anyone who finds the above nonsense convincing can simply read any definition of 'evolution' (biological) and 'abiogenesis' to see the difference. The relevance of all this is that ID is sold as an alternative explanation for evolutionary mechanisms, not those of the origin of life. However, if we are thinking that God is doing this, you can see how easy it would be to insert the creation of life in there. ---- "One of the problems with arguing against ID on the part of some is that they fail to understand that it is, in large part, an argument by analogy ." ---- >>>>This would be because it is not an argument by analogy. It's an argument by sophistry. However, rather than getting into that explanation, anyone can see that an argument by analogy is not scientific because it's an admission of having no empirical evidence. Why is this? Because there is no analogy necessary if the empirical evidence is actually there. The author may have meant 'inference', however even in that case it is again easy to see that it's an appeal to intuition most of the time, pretending that the invention of a 'designer' actually explains the things we see in biology. It doesn't: the designer ID proponents always point out, man, would design things quite differently, and this is where 'stupid design' comes in. Man designs things without the level of contingency we see in biology. Man, by planning ahead, can avoid silly actualities like the laryngeal nerve which takes what any designer would call an unnecessarily long and looping path. Why is this significant? Contingency in evolution explains these things, as evolutionary mechanisms tinker, they do not design. Parts can fold in on themselves (on an evolutionary time scale), they can change shape, etc, moving parts like nerves up, around, twisted... But a designer? No, that 'analogy' and 'inference' just lost all its supposedly intuitive explanatory power. This is why Dembski et al have presented a reductionist version of ID with incoherent concepts of 'information' and 'specification': they know that the general 'designer' does not act like a person, so they've attempted to cut off all other properties of the person outside of the mythical creation of 'specified complexity'. ---- "What this means is that we take an example of something that we know to happen and use this as an analogy for something about which we wish to theorize. This is done, for example in the SETI (Search for Extraterrestrial) program where the argument goes like this - 'We know that no signal from outer space could arise by chance, it must come from an intelligent life form, therefore if we detect one, we have discovered extraterrestrials.' This is essentially the type of analogy used by the ID people." ---- >>>>First, it is not an analogy. Second, it is not the inference made by ID proponenets. In SETI, the generic hypothesis goes like this: if intelligent life exists out in the cosmos, our only current way of getting even a hint of that directly is to scan EM frequencies. Similarly, the only intelligent life we have to go on, or at least the only intelligent life capable of creating such signals is us. In order to communicate with these signals, we must do certain things with them. Therefore, our best bet to find things out there like us is to look for signals like ours. How is the ID "analogy" like that? Well... it's not. Sure, it has the comparison to people, however it is not couched in the honest ignorance of those in SETI. It is not presented as, 'well, if a designer exists, we'd expect to see X, Y, and Z. Let's look for that.' That would be reasonable. It would also require ID proponents to actually do some science on ID, which we all know is far too much to ask. ---- "They are essentially saying 'we know that complex systems which are irreducibly complex and therefore require a whole lot of things to fall into place simultaneously do not happen by chance in the real world.'" ---- >>>>There's that weasel word again. "by chance". This is a concept which was disposed with all the way back at the origins of a mechanistic evolutionary theory with Lamarck and Darwin, both of whom had ideas of how lineages changed which depended on a deterministic environment. A short explanation of things wrong with the responder's point: irreducible complexity is a nonsense (and misleading-named) term. Similarly, in 'the real world', the poster is trying to appeal to one's everyday experiences. They may not have realized this, but a huge amount of evolution's history, and therefore the contingency which impacts current systems, occurred over vast amounts of time, periods which are almost unimaginably large. Unimaginably large periods of time are clearly not everyday experience and have significantly impacted what we see today in biological systems. ---- "Secondly, biological systems are also much more complex than the technology we observe to be designed, therefore, the conclusion is that these systems have been designed by an intelligence." ---- >>>>Now, this doesn't make any sense at all if we try to pin down the ideas of complexity and then look at the actual real world. It almost reads like bad religious apologetics in its blurring of what its terms mean. 'designed by an intelligence'? If you weren't appealing to intelligence as part of the 'designer' "explanation" in the first place, what is any ID proponent then referring to? How does the latter part of the argument follow from the first? More complex = smarter? If we take Dembski's version of complexity, which is garbled and non-explicit, and use the common information theory idea of information and specification, we'll find that increasing information means increasing the uncompressibility (randomness) of the set in question, something accomplished nicely by static or entirely random things. Now we get to throw the straw man of evolution as 'random' back in the ID proponent's face, as their obfuscatory terms result in a designer who maximizes randomness. However, there's also specification, which is the antithesis of that, so in the end the 'designer' is, by analogy, simultaneously hot and cold, also hungry and not hungry, as those things which possess these two contradictory properties are made by people, right? Apologies for the ramble. Yes, sarcasm was rampant throughout. ---- "This analogical argument is the central piece of argumentation supporting ID. It needs to be shown to be false to disprove ID." ---- >>>>Why disprove that which isn't disprovable and is based on a large slew of pseudophilosophy, pseudologic, and psueodscience? The problems with ID are so deep that 'disproven' is likely impossible, because ID hasn't even started to get an inkling of offering a 'proof' of any kind. The examples like the laryngeal nerve, the example of contingency or even the remaining function of a mousetrap tie clip are attempts to show how ID's declarations are not just wrong, but are deeply ignorant and illogical. Looking at how ID proponents deal with criticism is the best evidence for its lack of scientific, and logic credibility: a short slew of nonresponses followed by a declaration of how much the others 'don't understand', followed by an explanation of their position which is either consistent with the one criticized or so vague as to be meaningless. ---- "In other words, it needs to be demonstrated that life, in a very complex way can arise by chance." ---- >>>>This is just getting sad. Evolution is not abiogenesis. ID isn't even presented as a challenger to abiogenesis and all the poster is doing is exposing their underlying opinions, ones they'd prefer to keep secret. "This would basically be another form of 'spontaneous generation' disproved by Pasteur and formulated as the scientific law of Biogenesis - life only comes from life." ----Pasteur's experiments disproved the notion that entire flies arose from broth spontaneously, etc. These are entire, large organisms that by popular convention were often held to simply pop into existence, like mice being a product of improperly stored hay as opposed to the result of successful parentage. It is quite common for creationist to exaggerate the situation to the generality of 'life does not come from nonlife', though, as if scientists were not aware of Pasteur. It is a rather insulting idea, when you get right down to it. "It would also need to show, not just the spontaneous generation of life but the spontaneous development of complex structures in the DNA blueprint itself in an organism, in order for it to develop these irreducibly complex systems." ---- Another argument from ignorance/shifting of the burden of proof. The problem with ID is that it doesn't explain anything, it has no specific predictions which follow from its ideas. Even if there were absolutely no scientific explanation for how life changes or began, it would not make ID the default 'correct' answer nor would it fix the deep flaws in ID logic. "These are arguments against ID which remain to be proven, especially since they go against known scientific laws." ---- This is a perfect example of the arrogance ID inspires: it gives people the impression that scientists are unaware of Pasteur, it relies on an ignorance of scientific terminology and the scientific method, and first and foremost fallacy. Hopefully that wasn't too painful for everyone. To explain the origin of the DNA/protein machine by invoking a supernatural Designer is to explain precisely nothing, for it leaves unexplained the origin of the Designer. You have to say something like 'God was always there', and if you allow yourself that kind of lazy way out, you might as well just say 'DNA was always there', or "Life was always there', and be done with it. --Richard Dawkins, The Blind Watchmaker : Why the Evidence of Evolution Reveals a Universe without Design p. 141 "In December 2005, federal Judge John E. Jones III ruled that ID must meet the same fate that creationism met in 1987 when the Supreme Court ruled religious doctrines can't be promoted in secular institutions under the Establishment Clause of the First Amendment. Judge Jones wrote in his decision regarding a policy of the Dover, Pennsylvania, school district that added ID to the school's biology program: The citizens of the Dover area were poorly served by the members of the Board who voted for the ID Policy. It is ironic that several of these individuals, who so staunchly and proudly touted their religious convictions in public, would time and again lie to cover their tracks and disguise the real purpose behind the ID Policy...." " Two scientists often cited by defenders of ID are Michael Behe, author of Darwin's Black Box (The Free Press, 1996), and William Dembski, author of Intelligent Design: The Bridge between Science and Theology (Cambridge University Press, 1998). .... However, their arguments are identical in function to the creationists' arguments: rather than provide positive evidence for their own position, they mainly try to find weaknesses in natural selection. As already noted, however, even if their arguments are successful against natural selection, that would not increase the probability of ID." Excerpted from "Intelligent Design". Please see link..

Presumably, a really intelligent designer would always produce the best design. Yet the world is full of imperfect designs that could only be explained by evolution - the exact opposite of what is usually proposed by advocates of intelligent design. * Why would aquatic creatures such whales and dolphins have lungs, when gills are more suited to aquatic life? Science tells us that whales and dolphins evolved from land-based mammals. * Why do tree-dwelling koalas have their pouches opening downwards, risking the lives of their young? Science tells us that koalas evolved from burrowing marsupials similar to wombats, which have backward-facing pouches that avoid dirt getting thrown into the pouch. * Why do humans have: sinuses that drain upwards, causing so many people to suffer sinus problerms; poorly supported diaphragms; skeletons so unsuited to walking upright. Science tells us that when our distant ancestors walked on all fours, sinuses drained normally, diaphragms were supported appropriately and our skeletons were well suited to the task. If we answer the Intelligent Designer has been existing all along, then why not go a step further and state that everything has been in existing all alone. Intelligent Design does not provide good arguments to begin with and because of this its proponents usually attempt to shift the burden of proof. One of the answers above did just this, beginning with the argument from ignorance: if you don't explain how something arose, my answer is correct. This is how many of Intelligent Design's arguments work, it's fallacious, and it mirrors its antievolution creationist roots. The vast majority of Intelligent Design arguments are in fact arguments from ignorance, including Irreducible Complexity, the idea that a complex structure is too complex to have evolved with stepwise mutations. To be able to say this with any certainty, someone like Michael Behe, Irreducible Complexity's resurrector (see Paley's Watchmaker), would need to demonstrate that he has gone through all the possibilities and ruled them out. He does not do this and as such Irreducible Complexity relies entirely on shifting the burden of proof. When he could be doing research, he writes popular books that are easily refuted. It is this type of behavior that leads some to call Intelligent Design a science stopper. William Dembski, however, has provided a hypothetical argument that is not an argument from ignorance, something known as "specified complexity" and the "design inference". The little he has given in support of his idea has been thoroughly criticized by mathematicians and information theorists, however the strongest objection to his claims is that "specified complexity" is never openly-presented or fully explained, always to be found in his next book. Given his many predictions about the demise of "Darwinism", one would expect that if his ideas had any validity, he would release them over a ten-year period! Most of the arguments for specified complexity involve vague explanations of what specification and complexity are individually and describing designed objects as having high specified complexity. At no point is specified complexity presented as would be expected for any slightly-rigorous mathematical concept: in full, with work shown and clearly defined. There is scant else in the repertoire of arguments for Intelligent Design. A large number of the arguments are simply criticisms of mainstream evolution, usually based on lazy scholarship, which in no way establish Intelligent Design as anything better. In addition to this, Intelligent Design follows none of the rigors of science: there are no clear hypotheses, no testable predictions from those nonexistent hypotheses, and very little research done on the topic. The few "peer-reviewed" articles the Discovery Institute (the main political arm of the Intelligent Design movement) lists have been forced through in scandal without proper peer review (see the Sternberg controversy) or are from very strange journals, often with dubious connections, academic integrity, and little respect (like Rivista di Biologia). Some are often not peer -eviewed scientific papers and are rather opinion pieces while others have little or nothing to do with Intelligent Design. Essentially no papers by any Intelligent Design proponent include any original research, the bread and butter of any truly scientific enterprise. The next argument against Intelligent Design is how it is presented in the public sphere. Rather than acknowledging its flaws as unscientific (and often antiscientific), many fellows of the Discovery Institute, including Behe and Dembski, tout the strength of their ideas in the media, going so far as to postulate conspiracies within science as an explanation for why no one respects their ideas. They go even further and promote teaching Intelligent Design in public schools, self-publishing texts marketed to high school biology teachers and students as an obvious attempt to use political means when their efforts to convince scientists utterly failed. This partially led to Kitzmiller v Dover, which ultimately threw shame upon the town and cost the school district over one million dollars. The Discovery Institute's language also finds its way into a number of "academic freedom" bills in an attempt to undermine science education. As such, we can see that not only is Intelligent Design deeply flawed and unscientific, it is presented in a largely dishonest and fallacious manner to the public and scientists and undermines science literacy and good science education.

What cell theory contradicts evolution?

Cell theory does not contradict evolution. Cell theory states that all living organisms are composed of cells, while evolution explains how these cells and organisms change over time through the process of natural selection. Both concepts are supported by scientific evidence and are compatible with each other.

Are intelligent design and evolution scientific theories?

AnswerIntelligent design is not a scientific theory and evolution is. Explanations for questions about our world and everything in it are formed by using the scientific method. First, a scientist would come up with an explanation to an observed reoccurring pattern in nature, this is called a hypothesis. The hypothesis is tested by gathering more data and seeing if the data is supports or falsifies the explanation. If enough data is gathered, the hypothesis can be considered true and it becomes a theory. But even a theory is still subject to being falsified if enough data is found to prove it wrong (falsify). The theory of evolution is supported by data which was collected through observation of patterns and other events in nature. Some people don't like the idea that evolution is talked about in schools, because it contradicts many religious ideas (example: humans are not animals or related to them, the structure of organisms cannot change/evolve to be different and better because they were made perfect in the first place, etc.). So intelligent design was formed; and by calling it 'scientific,' some people thought they could put it in schools without violating the law that religion is not to be taught in schools. Intelligent design is not a theory because it has no data supporting it and there is no data to falsify it. So intelligent design is not a scientific idea, it is more like wishful thinking. AnswerEvolution is a theory that, in very general terms, states that today's species evolved by a process of replication and mutation with natural selection over a long time period from simpler life forms. This is accepted by mainstream scientists as the most likely explanation for our current species. Originally proposed by Charles Darwin, the theory of Evolution has been significantly refined by more modern discoveries in science, in particular the field of genetics and cellular biology, so the current theory of evolution is often referred to as the 'Modern Evolutionary Synthesis' reflecting the way it has incorporated these new discoveries.

Intelligent Design (ID) asserts that the universe and life forms we see today are best explained by design of an intelligent cause; Some ID proponents do not rule out adaptations of species, but they do not believe the addition of new complex information could have happened naturally. In other words, they believe natural variation within species is possible, but not new species. Both are trying to explain how the world works. Both claim to search for truth. Proponents of each believe they have proposed a theory.

Within science a theory is generally defined as a systematic framework that explains observations and experimental results, and which can be used to make testable predictions which in turn can either be used to refine or falsify the theory. Generally speaking scientists will attempt to test new theories by designing experiments that, if successful, will falsify the theory. All scientific theories and results are considered tentative and subject to revision or refutation as more evidence is gathered.

Scientific explanations for questions about our world and everything in it are formed by using the scientific method. First, a scientist would come up with an explanation to an observed reoccurring pattern in nature, this is called a hypothesis. The hypothesis is tested by gathering more data by observation and experimentation to see if the data supports or falsifies the explanation. If enough data is gathered, the hypothesis can be considered to have been validated and it becomes a theory. But even a theory is still subject to being falsified if enough data is found to prove it wrong. Scientists must publish the results of their experiments, and explain their hypotheses and theories in scientific journals so that other scientists are able to understand their work. It is also important for experiments and theories to be explained in a way that allows other scientists to reproduce the experiments or devise new ones that can either support or falsify the theory. When scientists try to publish their experiments the work must first be peer-reviewed. This is a process where the work they want to be published is reviewed by a selection of other experts in the field (peers) before it is accepted for publication.

The theory of evolution is supported by data which was collected through observation of a wide variety of natural systems and through laboratory experimentation. Most palaeontologists consider the fossil record to provide evidence completely consistent with the theory of evolution and geneticists also consider evidence from the study of genes to also be consistent with evolution. These two separate strands of evidence are also consistent with each other and have been used to successfully make predictions.

Scientists would further argue that Intelligent Design is not a theory because it has no data supporting it and there is no possible way to falsify it. Intelligent Design supporters argue that the evidence to support them is in the inability of current scientific theories to explain how certain features in biological systems came about naturally and that it is impossible for these features to occur naturally so they must therefore be the result of Intelligent Design. Many scientists consider this argument to be invalid and little more than an attempt to insert God, or an Intelligent Designer, into any current gaps in scientific understanding. This is often referred to as the 'God of the gaps' argument. Although the progress of scientific research can constantly fill these gaps in our knowledge this aspect of the Intelligent Design hypothesis could never be falsified because it can always be reapplied where there are still gaps in our understanding.

Some Intelligent design proponents argue that Evolutionary theory is a psuedoscience which lacks any significant empirical evidence to support it whilst others have chosen to argue that Intelligent Design should be taught as a valid alternative to Evolution within science education. Opponents of Intelligent Design argue that it is unsupported by evidence whereas, in their view, the evidence to support Evolution is overwhelming.

The majority of the scientific community have so far rejected Intelligent design as unscientific, amounting to little more than an untested (and some would argue un-testable) hypothesis that has produced no experimental evidence. It should be noted that accepted theories in science can and are overturned when experimental results are published that successfully falsify the prevailing theory.

Evolutionary theory is often criticised for failing to explain the origins of biological life, and that it is a theory that excludes the possibility of a supernatural god, and as such is atheistic in nature. In reality Evolution is explicitly not a theory concerning the origin of life, or the origin of the universe. It assumes the existence of life and is concerned with explaining how these living systems change through successive generations, developing new traits and ultimately creating new species, or as Charles Darwin put it 'the Origin of Species'.

The theory of Evolution within modern science does not explicitly exclude the possibility of an intelligent designer, either as the designer of the first living matter, or of the universe as a whole. Because science is a discipline that attempts to explain observed facts in terms of measurable physical reality it does not allow supernatural entities as part of its explanations or theories because they are incompatible with the scientific method, even if they actually exist. Many scientists have supernatural or religious beliefs but they do not rely on them when using scientific methods to understand the world. Some evolutionary scientists believe in a form of supernatural origin or intelligent design to the universe and that the mechanism of evolution was designed to do precisely what scientists observe it to do.

Each of these proposed theories starts with presuppositions. Evolutionary Theory and other scientific theories begin by assuming that everything we can observe and measure can be explained in terms of natural processes. ID assumes that supernatural design is possible and that its effects can be observed. ID scientists do not challenge the idea of change over time in organisms -just that the addition of certain complex biological information proposed by evolution is impossible without the intervention of an intelligent designer.

AnswerEvolution is a scientific theory. Intelligent design is not. Evolution, at least as it is presented in modern evolutionary synthesis, is fact, and is presented as such. Intelligent design is a religiously spawned doctrine that has social and political aims or goals as its objectives. Supporters of intelligent design present the oddest assortment of ideas as regards scientific support for accepting intelligent design as something scientific. The major scientific organizations around the globe uniformly and categorically reject it as unscientific.

What are the six scientific advances since Darwins death that have provided support for the theory of evolution?

There is nothing newly or old that support Darwin's evolution theory.Some of scientists reject Darwin's Theory of evolution and some of them don't.

t

I personally support it fairly due to my own beliefs and other scientist reject it for their on. Don't think that what you read in the Internet is always correct. The edge of science will always be on debate.

Let me note that Darwin lived in another era and the ability of explaining natural laws was not even close than the way we can explain it today.

So for me he earned my respected.

How did Charles Darwin use the concept of density-dependent factors in his theory of evolution?

Charles Darwin used the concept of density-dependent factors to explain how competition for limited resources could influence the survival and reproduction of different individuals within a population. He observed that individuals with advantageous traits that allowed them to better compete for resources were more likely to survive and pass on their traits to their offspring, leading to gradual changes in a population over time. This concept of natural selection forms a key component of his theory of evolution.

What adaptations might evolve in our species via natural selection?

Our species is known to have adapted a lot over the past few hundred or thousand years. Lactose tolerance is a recent adaptation, as well as the ability to break down complex carbs and refined foods. The ability of a group of people to digest different kinds of foods is still affected by natural selection - the more fatty foods Americans eat, the more people with weak hearts die from heart disease. The more people in Japan and other places eat salty food, the better their livers can deal with it, and so on.

Humans are also getting taller. A few hundred years ago, the average height was about 1 foot shorter than it is today. The average lifespan is getting longer, we're getting smarter, and we're going bald because hairy heads no longer carry a selective advantage.

What led up to Charles Darwin's discovery?

Charles Darwin's studies in the natural world actually led up to the discovery of natural selection. Darwin observed the population barnacles and later pigeons to observe variations as they were crossbred within their own species.

What is your comment about the theory on biological evolution?

My comment is that it is not a theory but yes a fact. (Just to correct you...)

And of course, Evolution is the real thing, we humans evolved from other animals, and life doesn't existe only for a couple of thousands of years but yes for thousand thousands more. What you have to bare in mind is the evidence of this. Geologists and biologists and even chemists have proven that evolution did happen and still is happening.

Check out Charles Darwin and Richard Dawkins to have a better idea about evolution. You may also look at the pbs site, because they have mada an extroadrinary documentary about evolution and they have some things on their web-site. Just search for Evolution. Hum, you there can see everything, and check out Sir Kalvin, he was the one who started agreeing with Charles Darwin, affirming that the planet earth has been formed much before when they said it had been formed, based only on the temperature earth irradiates from its geocentre. The pope, also approved evolution, he couldn't devy it with so many facts.

How can one not accept evolution??

Hope my opinion jelps in some way! :)
Present-day organisms on Earth had developed from earlier, distinctly different organisms.

How and why Darwin conclude that life stems from common orgins and ancestors?

Darwin discovered through observations of nature that the natural world was not built as-is, as was previously thought, and that species had lived that are now extinct. Eventually he figured out the mechanism by which these changes occur and after that it wasn't a huge leap to look at a horse and then a zebra and a giraffe etc and realize they came ultimately from one ancestor because they have inherited traits which are the same.

That, in other words, the family tree of life on earth forks.

If you can see the similarities between a horse and a zebra and a human and another primate, you can see the similarities between all mammals, all animals, and eventually (with modern genetics) all life on earth, including plants, insects and microscopic life.

Can evolution occur without natural selection?

Natural selection is the differential fitness of diverse phenotypes, causing some individuals to reproduce more than others according to their own relative fitness. Evolution is the change in gene frequencies of a population between generations. Therefore, natural selection can indeed occur without resulting in evolution, as changes in mean fitness do not necessarily lead to changes in gene frequencies.

For example, a deleterious allele may affect only homozygotes in a population. Thus, homozygotes may be selected against in equal proportions, causing them both to decrease in frequency at the same rate. While heterozygotes would have higher fitness, the mean change in frequencies would still equal zero. Both the dominant and recessive alleles are still present at the same frequency as before they were acted on by selection, due to the relative increase in heterozygotes.
