Describe three holes in Darwin's theory?
Darwin only had one theory of evolution, and he defined it in his book On The Origin of Species.
This question is confusing/mixing-up two different scientific theories, and should be worded something like: "What is Darwin's theory of evolution?" 'The Origin of Species' (1859), a book by Charles Darwin explaining his theory of evolution provoked great controversy: by casting doubt on the …historical accuracy of the biblical accounts of Creation it caused many believers to question their faith in Christianity. . Another scientist, Albert Einstein, proposed a "General theory of relativity" that has nothing to do with Darwin's theory! Technically correct attribution of theories aside, Darwin's theory of 'relativity' is that all living things are relatives! ( Full Answer )
1) All living organisms are composed of one or more cells 2) Cells are the basic units of structure and function in an organism 3) Cells only come from the reproduction of existing cells.
Basically that species adapt to their environment by changing anddeveloping gradually, thus becoming more successful and bettersuited to survive and multiply. Species proliferate through variation (mutation) with commondescent (inherited characteristics) and natural selection. Darwin's theory propo…ses most of the species today arose throughgradual changes in previously existing species. All mammals, forexample, inherited traits from some common ancestor. Because whalesare mammals, they would have evolved from some terrestrial mammal.All terrestrial vertebrates (mammals, birds and dinosaurs,reptiles, and amphibians) would share common ancestry with someamphibious ancestor that lived several hundred million years ago. One bit of evidence in support of this theory is that allterrestrial vertebrates (including cetaceans) have inherited thesame amphibious body plan for limbs, backbone, pelvis, and ribcage, similar to that of the sarcopterygian lungfish from which itappears they share common ancestry. Reptiles, dinosaurs and birds are all diapsids. Mammals aresynapsids. Turtles are anapsids. If evolution were wrong, therewould be no reason for this to be the case. Darwin's theory of evolution is often stated as: 'Survival of theFittest" (though Darwin NEVER said this) or "Natural selection."More precisely, it amounts to the idea that when an organismdiffers from its family and neighbours in such a way that it canproduce more young that in turn can successfully produce moreyoung, its line will increase and eventually displace its lesssuccessfully reproducing rivals.That is what a revolutionaryfitness amounts to. Note that not just any difference will do; thedifferences have to be heritable - they must pass on from parent tooffspring, or they will have very little to do with evolutionthrough natural selection. Genetic mutations occur in every species. Sometimes these arebeneficial. For example a calf born more muscular than the restwill be more likely to mate and consequently pass on his genes tohis offspring. There are hundreds of others, but the suggestion: 'Or Google"evolution Darwin" ' is strictly for people who already have a goodbasic understanding of the field. Although there is a lot of goodstuff on Google, for every reliable article on evolution, you haveto dig it out of a torrent of garbage. For some peculiar reason,Darwinism in one form or another has been selected as the archenemy by every second dishonest evangelist (and there are thousandsof them!) and a lot of evangelists that may be honest enough topreach, but not honest to get their facts on the subject straight.If they were to seriously study the subject, they could tell thatit has practically nothing to do with scripturally based faith. Remember a very important point if you begin to study evolution inbiology (or related concepts too, in fact): The principles are sosimple that most people who first hear of them say something like:"Oh! How easy! I understand that; it is obvious!" The fact is thatalthough the principles do seem easy, it does not follow that thewhole subject is easy. It is a beautiful subject, but it requiresserious work and careful thought to avoid making a fool ofyourself, whether you are a genius or not. To imagine that becauseits principles are simple, a subject is simple, is an error. Abrick may be easy to pick up, but it does not follow that a housemade of bricks is easy to pick up. The basic principles ofmathematics are simple too, but that does not mean that mathematicsis a subject for the simple-minded. Much the same is true forevolution. Don't let me put you off; it is a lovely, lovely subject, but it isnot a subject that you can master by reading a book about it, notanyone's book. Developments since Darwin The theory of (biological) evolution hasadvanced since Darwin's time. For example: . Although Mendel lived in Darwin's time, his work on inheritancedid not become widely known until later. In fact, in theintroduction to his book, Darwin admits to being perplexed aboutthe very question that Mendel answered. Mendel's conclusion was (inmodern terminology) that every organism has 2 copies of each gene,one inherited from each parent (each chosen randomly). The emergentfield of molecular biology led to the demonstration that DNA is themedium on which genetic information is written, and to thediscovery of its structure by 1953. Since that time advances in thefield have lead to dramatic changes in our ideas of what a genereally is, and some of its implications for the theory ofevolution. . Furthermore, the relevance of Mendel's work to Darwin's theorywas far from obvious; for some decades some people regarded the twobodies of work as being in conflict. It was not until the mid-20thcentury that they were united in what we now know asneo-Darwinism.People ignorant of the subject regard that as acriticism of evolutionary theory, but it is nothing of the kind; itwas simply the addition of new knowledge and new insights topioneering work (real work; not idle handwaving!) that already wasbrilliant in its own right. Neo-Darwinism is an enhancement ofDarwinism, not a negation. . Darwin assumed that all changes in a species must be gradual.But we now know that genetic information is stored digitally, fromwhich it follows that even a small mutation can cause a largechange in an organism - for example, a whole gene can be rendereduseless by just one point mutation. Furthermore, since Darwin'stime, science has come to terms with some erratic aspects of theworld, such as chaos theory and quantum mechanics. Darwin'sassumption was arguably a product of this limitation in thescientific thinking of his time. . In the 1960s, Hamilton derived mathematically a solid basis forpredicting the extent to which an organism will show altruismtowards its relatives. His prediction was that it would treat whatthe evidence suggests should be its sibling as having roughly halfthe value of itself. What it sees as its own young usually is alsoworth roughly 1/2; a nephew 1/4; and so on. It is now possible touse game theory to analyze the behavior of organismsquantitatively. Previously, only qualitative arguments werepossible. . Apart from the more theoretical developments mentioned above,scientists sometimes change their minds about the exactrelationships between different species. In particular, the recentavailability of increasingly cheap techniques for geneticsequencing has created a new source of evidence. One surprisingobservation is that the relationships between single-celledorganisms over billions of years do not appear to follow atree-like structure. In other words, there has been exchange of DNAbetween very different species of single-celled organisms. It isalso believed that certain parts of cells, called mitochondria andchloroplasts, were once independent organisms, which developedsymbiotic relationships with their host cells. I agree with the "Developments" paragraphs, but would like toremark about the bit: "...scientists sometimes change their mindsabout...": John Maynard Keynes said:"When the facts change, Ichange my mind sir. What do you do?" Remember that when scientistsworthy of the name change their minds, it is because the facts attheir disposal have changed. One of Charles Darwin's theory is named The Origin ofSpecies which he discovered during the visit of an archipelagoof volcanic islands, Charles discovers a massive amount of diversespecies. From this, he deducts that animals with variations bettersuited to their environment would have a better chance of survivaland ability to breed. They would then pass on the favorablecharacteristics to their offspring. ( Full Answer )
The idea that organisms could change with time pre-existed Charles Darwin. However, it was Darwin himself who gathered the first major evidence into the definitive book on the subject The Origin of Species . Darwin's addition to the concept of change of organisms across time was the concept of sele…ction. There are three types of selection: Artificial Selection, Sexual Selection and Natural Selection. He used Artificial Selection to back up the hypothesis that organisms harbour within themselves the capacity to change from common ancestors. Artificial Selection is obvious, as should be the notion that life derives from common ancestry. Chihuahuas, Alsations, Dachshunds etcetera have all been artificially selected and derive from the Canis lupus common ancestor. Birmingham Rollers and many other breeds of pigeon (Darwin bred pigeons so would know what he was talking about) derive from the Columba livia common ancestor. Artificial Selection is simply an illustration. It seems Natural Selection should be the true ruler of Selection in the wild undomesticated world. Natural Selection states that whatever has a morphology or biochemistry or behaviour that does not allow it to survive and reproduce, will not do so. Desert animals do not have thick coats. Ptarmigans are not black in winter. Birds have airsacks in addition to lungs. Gazelles have eyes on the sides of their heads and as a result are better able to scan for predators. In other words, from predarwinian change-thoughts, a mechanism for that change had been added by Darwin, that whatever is around today is the result of Natural Selection. But Natural Selection is simply the selector of what change survives and what doesn't. The change itself is brought about by genetics. Mendel's Genetics knowledge came too late for Darwin to add into his own work. DNA was only discovered by Watson and Crick in 1953. The story of Darwin ended and modern genetics took over, explaining where change comes from. DNA replicates prior to gametogenesis and errors are made by the enzymatic processes that replicate the DNA. During meiosis, DNA is randomly segregated, splitting maternal and paternal chromosomes into separate and randomly assorted gametes, giving high possibility that the offspring should differ slightly from their parents. Now, the picture is even more complex; chromosomal rearrangements during meiosis may reproductively isolate the offspring of a pairing. See articles on chromosomal rearrangement in muntjaks and many rodents for more information. There is also a fossil component, displaying past evolution. Darwin predicted that there should be transitional forms between major taxa, and he was right. Archaeopteryx (discovered 1859) is transitional between coelurosaurs and birds. Tiktaalik , Ichthyostega and Acanthostega show the evolution of the amphibian leg from the fish's fin. Mammal-like reptiles of the Permian show the evolution of the mammal jaw. There are many australopithecine and Homo intermediates between early apes and Homo sapiens . There are many species of extinct elephant and horse and giraffe and seal and Ambulocetus and Rodhocetus show the evolution of the whale. Thus I would phrase The Theory of (Darwinian) Evolution by Means of Natural Selection as a theory of how life comes to be as it is, via change, at any moment of time. It is documented by the fossil record which shows how past life evolved to the present life we see now. Genetics and cytogenetics show how new species arose (past) and arise (present) and how the change itself occurs. Natural Selection explains how the change that emerges genetically is either 'selected' or 'not selected'; in other words how the survival of what morphologies and behaviours can survive, do survive, whereas the morphologies and behaviours that fail when faced with the environment, do not survive. And central to the theory, all life proceeds by common ancestry. ( Full Answer )
That concept of " the survival of the fittest " was coined by Herbert Spencer and is not quite accurate even though Darwin used the phrase in later editions of The Origin. Darwin's theory is called the theory of evolution by natural selection and this is a simplified explanation of it. Natura…l selection is the nonrandom survival and reproductive success of randomly varying organisms leading to allele changes in populations. ( Full Answer )

Describe three of Darwin's observations about animals in South America and on the Galapagos Islands?
1) Finches have different colors in different areas. 2) Finches beak size depends on their diet 3) Tortoises are larger where there are less predators.
Typically, Christians do not oppose evolutionary theory. Many Christians are able to combine acceptance of scientific theories with a belief in the unique and divinely determined purpose of Mankind. There is however a subset of Christianity, and of other religions as well, adhering to the notion o…f creationism . Creationism holds that Mankind is not just special, but was specially created , in its current form, separate from all other lifeforms. This belief is largely based on a literal interpretation of the relevant scriptures on which their doctrine is based. These creationists oppose evolutionary theory because it contradicts that notion of special creation. ( Full Answer )
Darwin believed that and animal changed over many lifetimes, once it is adapted it passes on its genes for futer generations
We have fossil stromatolites billions of years old, proving the oceans teemed with simple single celled organisms for eons before the first multicellular marine organisms came into existence some 650 million years ago. We know jawless fish predate jawed fish, and sarcopterygian lungfish predate the …fishapod Tiktaalik. Tiktaalik predates the earliest devonian amphibians, which had to await the colonization of land by early flora and insects for their to be new niches for them to exploit. All of this fossil evidence points to a gradual evolution of the species, just as Charles Darwin described. Since the publication of his theory we have developed whole new lines of evidence in support of evolution, such as genetics and cladistics. We have observed speciation and evolution occur in the wild, and artificially in laboratories at rates higher than would be required to explain the diversity of life we now find. There are also numerous studies of genetics lending support to Darwin's theory. Pseudogenes and viral DNA insertions both are indicative of common ancestry. Humans have 23 pairs of chromosomes, whereas other old world primates have 24 pairs. We have identified the pair of chromosomes that fused to reduce our number. These fused chromosomes even possess remnants of the telomeres--DNA sequences marking the ends of a chromosome--embedded where the original pairs joined. You could hardly hope for more compelling evidence for common ancestry between humans and simians, but there is much more evidence besides. ( Full Answer )
His first paper was titled:- 'On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection' His book was titled 'On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Lif…e' (usually abbreviated to On the Origin of Species). In these publications he set described things/features that could be seen in the biological world and presented a process by which these could arise over time, with evidence to support these proposals. As such his publications conform to the scientific method and may be called a theory. His proposals are now well accepted as being a correct/true description about how the variety of life as we know it came to be on our planet and form the basis of modern evolutionary theory.. In scientific terminology, a theory is a proposal/explanation with evidence that could be defended (a fossil record, the different bird specie variations, etc.) and an idea that can be used to predict further developments; in this case, that there have been/are/will be major changes to an organism's DNA/RNA over time as it adapts to its environment, which can be proven with a decent microscope and some bacteria, and common acceptance in the scientific community (tick this box).

2009 is important for Darwin's theory of Evolution as that is the 150th anniversary of the publication of On the Origin of Species the famous book by Charles Robert Darwin himself. To celebrate this occasion, Richard Dawkins published The Greatest Show on Earth , Jerry A. Coyne wrote Why Evoluti…on is True and Sir David Frederick Attenborough presented Charles Darwin and the Tree of Life , a charming television documentary. ( Full Answer )
He found fossils of creatures from the past that are similar (but not identical) to creatures today. There are numerous fossils of transition species. Some of the most famous are devonian amphibians like acanthostega and eogyrinus, the fish/amphbian tiktaalik, and the bird/reptile transition archaeo…pteryx. Molecular biology also supports Darwin's theory in terms of inherited sequences. ( Full Answer )
That trough time, a specie of animal, plant, bacteria can change. When a life form reproduces, one of its"babies" may be different from its parents because of genetic mutation. Sometime, this mutation may give it an advantage over other individuals of its specie. (e.g.: A giraffe has a higher nec…k and can search food on high trees.) Because of this advantage, the life form that is different ( we will call it A ) can live longer and has better chances to reproduce. The life form that has not this advantage ( we will call it B ) will live less longer and will have less chances to reproduce. Because of that, the population of "A" will increase and the population of "B"will decrease. In the end, there will only be "A". ( Full Answer )
yes Alfred Russel Wallace wrote an essay called "On The Tendency of Varieties to Depart Indefinitely From the Original Type", which outlined a nearly identical theory independently of Charles Darwin's Theory of Natural Selection. Wallace sent the essay to Darwin, for his opinion. Upon reading i…t Darwin was prompted to publish his own theory which he had been writing for many years. Though Darwin got all the credit, he did in fact submit Wallace's essay along side his own to the Linnean Society of London. ( Full Answer )
1. Finches are anatomically similar but have different colours in different areas and their beaks depend upon their diet. 2. Tortoises are larger on the islands, where there are fewer predators. 3. Animals vary within species and reproduce to the extent that some must die
1. The principle "problem" is that it does not incorporate abiogenesis--the origin of life itself. Darwin's theory does a superb job of accounting for speciation, the great diversity of life we find on this planet. It is apparent all life originated from one to three common ancestors. Whether eu…karyotes, prokaryotes and archaea share common ancestry or not is unknown. It is possible life arose three or more times. Yet no process for the origin of life is well detailed. We have at best murky possibilities, such as an RNA world preceding our "DNA" world, and so on. 2. Darwin's theory, when originally proposed, did not account for mechanisms of variation. This problem has since been resolved with the discovery of inheritable mutations in the structure of the "recipe" molecule deoxyribonucleic acid (DNA), and the incorporation of molecular biology in what has become known as "the modern synthesis." 3. Although any scientific theory will suffer trivial defects, and evolution is no exception, I am at a loss as to what might constitute a third "main" problem of the theory. It has no competitors, a hallmark of a fairly strong and robust theory. That in itself could be considered a problem. Theories with decent competition provide fertile ground for the progress of science, in the testing between alternatives. There are no strong contenders for the origin of species within the field of biology, leaving evolutionary biologists little to do besides dot the i's and cross the t's. ( Full Answer )
First of all, the fossil record does not support the theory of evolution. The fossil record shows that species abruptly appear and disappear, almost as if they were created. There is absolutely no evidence in the fossil record of species gradually changing into different species. Darwin himself said… that these revelations in the fossil record could be used as the most compelling arguments against his theory. Secondly, in order for Darwin's theory to be plausible, it needs vast amounts of time (thus, evolutionists claim that earth is millions and millions of year old). But for the earth to be old enough to accommodate Darwin's theory would be impossible. The intensity of the electromagnetic sphere around the earth steadily and consistently decreases by seven percent about every one hundred years. When we look back in time and calculate the intensity of the electromagnetic sphere by adding seven percent every hundred years, we find that the electromagnetic sphere was so intense just twenty thousand years ago, that it would have literally dissolved the core of the earth. How then can the earth be billions of year old? Thirdly, Darwin made his theory in the 1800s. Science has grown by leaps and bounds since then. Here is an example: Genetics was not developed as a science in Darwin's day, and he assumed that animals essentially had an unlimited capacity to adapt to environments -- unaware that no change could ever take place without the right genes being there. To resolve this dilemma, modern evolutionists asserted that the fish's genes must have mutated into human genes over eons. Mutations, of course, are abrupt alterations in genes. However, this hypothesis is no longer tenable. Dr. Lee Spetner, who taught information theory for a decade at Johns Hopkins University and the Weizman Institute, spent years studying mutations on a molecular level. He has written an important new book, "Not by Chance: Shattering the Modern Theory of Evolution" In it, he writes, "In all the reading I've done in the life-sciences literature, I've never found a mutation that added information. ... All point mutations that have been studied on the molecular level turn out to reduce the genetic information and not increase it." ( Full Answer )
Darwin's theory noted that all living things vary, and many of those variations are heritable. Living things tend to reproduce in greater numbers than replacement would require, so in general, not all individuals can leave successfully reproducing offspring in the next generation. If any heritable v…ariations have an influence on reproductive success or failure, the successful variations will become more frequent in the population and the less successful ones will become less frequent. This is natural (and sexual) selection, and accounts for change (evolution) in living creatures. Evolution accounts for species transforming into different species and species splitting into multiple different species. It concludes that all living things are related by common descent. The past tense is correct when talking about Darwin's theory of evolution because the theory has been greatly refined and expanded since Darwin's time. ( Full Answer )

One of the major questions which biologists must answer is how organisms become adapted to their environment. Before Darwin the most widely accepted answer was special creation ie God had created all species as they are now. In fact the occurrence of adaptations was one of the arguments put forwa…rd for the existence of God. Darwin's idea of natural selection provided an alternative explanation to special "fiat" creation. He proposed an explanation consistent with his observations of nature and the fossil record.

Charles Darwin basically stated the following on his theory of evolution: . Inherited variation exists within the genes of every population or species (the result of random mutation and translation errors) . In a particular environment, some individuals of a population or species are better suit…ed to survive (as a result of variation) and have more offspring (natural selection) . Over time, the traits that make certain individuals of a population able to survive and reproduce tend to spread in that population. . There is overwhelming evidence from fossils and many other sources that living species evolved from organisms that are extinct. i hope this helped :) ( Full Answer )
\nIt denotes Darwin's specific view of how evolution works. Darwin developed the concept that evolution is brought about by the interplay of three principles: variation (present in all forms of life), heredity (the force that transmits similar organic form from one generation to another), and the st…ruggle for existence (which determines the variations that will be advantageous in a given environment, thus altering the species through selective reproduction).

I only have two, sorry :P . when his daughter died, he started questioning the existence of God. . Wallace persuaded him to publish his book on his theory of evolution. hope this helps!
In simple terms, two things. One, that if a species is placed in a situation where it must either adapt or die, only the strongest of the species will adapt and survive. The weaker of the species will die. This also applies to groups of species in competition - the stronger will live, and the wea…ker will die, hence, "natural selection." Two, that, based on the natural selection and natural adaptation principles above, humans could not have been the way they are from the beginning of life on Earth. They evolved from another species, being an end result of a prior species' adaptation to their situation. (For the record, and for any who stumble upon this, Darwin NEVER said that we evolved from chimpanzees. He stated that humans have a common ancestor with those lovable - but dangerous - monkeys. And, as any well-rounded scientist should, he never stated that the above was fact, hence why it is a THEORY of evolution and not a LAW of evolution.) ( Full Answer )
1) A group of organisms tend to reproduce more offspring than the environment can support. 2) Most populations tend to remain fairly constant in size because of various population regulation mechanisms at work, e.g., density-dependent factors and density-independent factors regulating population …size. The population comes into an equilibrium with its present environment. (See your notes.) 3) Competition takes place because so many individuals are introduced into an environment with limited resources. There is a "struggle for existence." Such a competitive struggle for existence usually includes being better adapted for obtaining the available resources in comparison to other individuals. Especially note that physical combat is not a very important part of this concept. 4) There exists variation among individuals within any species because genetic changes occasionally occur that modify the DNA structure of chromosomes. 5) Variations caused by gene mutations are usually either harmful or useless. However, over the course of time, beneficial mutations may occur. Individuals that inherit beneficial mutations or beneficial gene recombinations are better adapted to survive. This is where the phrase "survival of the fittest" comes in or the process of natural selection. Again note that such a competitive struggle for existence usually includes being better adapted for obtaining the available resources in comparison to other individuals and that physical combat is not a very important part of this concept. 6) In a changing environment, those organisms with favorable genetic variations survive. The surviving organisms then reproduce and transmit their DNA to their offspring. Over a long period of time ENTIRELY NEW SPECIES EVOLVE. Organisms that have successful genetic variations not only live longer but produce more offspring who also inherit the favorable adaptation. ( Full Answer )
The theory, in abstract, was first put forward at the Linnanean Society sometime in 1858. On the Origin of Species was first published on November 24, 1859.
there is a variation in every population and organisms compete for limited resources and organisms produce more offsprings that can survive,organisms pass through genetics traits on to the offsprings .
He didn't. Lamark's theory of acquired characteristics preceded Darwin's theory by some years. Almost 50 years.
Simply put, to understand the unity and diversity of life. " Nothing in biology makes sense except in the light of evolution. "
Darwin collected thousands of specimens across the world. Like other naturalists before him, Darwin noted similarities in the species that contributed to their classification. But Darwin also had fossils detailing changes that had occurred over vast stretches of time. Darwin noted pigeon breeders… could introduce stable changes in a population via a process of artificial selection. He also saw that nature introduced its own changes in species. Although there is a huge diversity of life, Darwin saw how it was organized and how it must have changed over the ages. Not long after he published his theory, a fossil of Archeopteryx was discovered, showing the link between birds and dinosaurs. Later fossils of Neandertal were discovered, demonstrating the existence of multiple hominid species in prehistoric ages past. ( Full Answer )
The finches: the theory was supported by when he visited the Galapagos islands and the finches were blown to another island and they had to adjust their beak size to live and eat.
Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related. Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (u…ndirected) "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature). In La mins terms; It states that every creature is related, that we started as fish, which eventually evolved into a variation, and so on, until they could breath air, walk, understand, and until they looked nothing like the original.

It has been argued from the earliest publication of Darwin's theory of evolution that since the bible describes the creation of species as an instantaneous process, performed by God, rather than an evolutionary process resulting from natural selection, Darwin's theory is religiously unacceptable.
It's not. Actually, biogeography, the geographic arrangement of convergent and divergently evolved species supports the theory of evolution by natural selection.
