Evolution

Tepig evolves into Pignite.

Those terms need to be done away with. There is no such division in the theory of evolution by natural selection, even in Darwin's time. There is evolution and speciation. One flows seamlessly into the other over time and we have myriad pieces of evidence supporting this.

Evolution, the change in allele frequency over time in a population of organisms, is a fact. The theory of evolution by natural selection explains much of this fact.

That is what a theory is. A consistent explanation of a phenomenon, or a series of phenomenon, that is supported by massive amounts of evidence, containing both facts and laws and is able to make predictions that generate testable hypothesis.

A theory, in the scientific sense, is not a guess.

Comparing organisms can show similarities in their DNA, anatomical structures, and developmental processes. These similarities suggest that the organisms share a common ancestor and have evolved from it through the process of descent with modification. By studying these similarities, scientists can trace the evolutionary history of different species and understand how they are related through common ancestry.

Speciation is the process by which new species arise from a common ancestor. This can happen through various mechanisms such as geographic isolation, genetic mutations, and natural selection. Over time, different populations may accumulate enough genetic differences to become reproductively isolated and develop into distinct species.

The individual who is most likely to be considered the fittest in terms of natural selection would be the one who is most successful at reproducing and passing on their genes to the next generation. Fitness in evolutionary terms is about how well an organism can survive and reproduce in its environment, so the individual with the most offspring who survive would be considered the fittest.

Look at a population of humans. Your class will do. Now, how many different heights, hair colors and other assorted phenotypic variations can you see in this small population?This is the frequency of alleles of these types that we call natural variation.

Evolution causes the appearance of a new species through mutations in exisiting lifeforms. Natural selection is the method through which species become greater or lesser in numbers. For example, if you have a bunch of blue butterflies and a bunch of brown butterflies in a forest that is primarily brown,green, and black, then the blue butterflies have a greater chance of being eaten by predators than the brown butterflies because the brown ones could camoflauge themselves next to a tree. The blue ones would decrease in numbers and not be the most "fit" for their environment due to this process of natural selection.

Hope that rambling answer helped :)

One unintended consequence of the theory of evolution is the misconception that it promotes the notion of "survival of the fittest" as a justification for social inequality or unethical behavior. This misinterpretation can lead to misunderstandings about the complexities of evolution and human behavior. Additionally, some may use evolution to support eugenic ideologies, which can have harmful implications for society.

If it is easier or more likely that an organsim is going to survive and reproduce if that organism works together with another or takes advantage of a certain opportunity, natural selection will favor the organisms that are more suited to maintaining their realtionship with the other organism.

An example of micro-evolution is the development of antibiotic resistance in bacteria due to natural selection. When exposed to antibiotics, bacteria with genetic mutations that provide resistance to the drug survive and reproduce, passing on the resistant trait to future generations. Over time, the proportion of resistant bacteria in the population increases, leading to the evolution of antibiotic-resistant strains.

Genetic Drift (or allelic drift) is the pseudo-random chance that a minor genetic change will eventually become a fixed genetic inheritance in a specific organism. IT is the underlying principal in the theory of evolution. There are many equations and probabilities involved, but the basic explanation is that as the number of generations with the genetic change increases, so does the chance that the change will become the norm, rather than the aberration.

Studying the Precambrian time is challenging due to a lack of well-preserved rocks, limited fossil records, and the immense timescale involved (4.6 billion to 541 million years ago). Additionally, geological processes have altered many Precambrian rocks over time, making it hard to interpret their original characteristics accurately.

The idea that evolution is a directed process with a predetermined goal or purpose is not part of Darwin's theory of natural selection. Instead, Darwin proposed that evolution occurs through random variation and selection based on the fitness of individuals in a given environment.

Evolution never stops, although at times it is a very slow process. An organism that is perfectly adapted to its ecological niche would experience no evolutionary pressure, but then, no niche stays the same forever; the environment changes, and organisms must adapt.

Basically, it's marriage to genetics. Early 20th century geneticists thought that natural selection was too weak to take random mutation and do anything with it. The founders of population genetics and systemists in biology by mathematical paraphernalia showed that gradual allele frequency change over time in populations of organisms was possible ( supported by experiment since ) and jumps in mutational events were not necessary.

Plus the fact that Darwin's original theory had a mechanism of heredity, blending, that could not work with natural selection.

New species emerge as a result of reproductive isolation between subpopulations followed by continuing divergence at the genetic and behavioural level. This process is called speciation.
Evolution is the gradual process in which already existing species undergoes in order to have a greater chance of survival. Because Natural Selection takes place, random mutations occur in offsprings, and so new characteristics and attributes are formed. These random mutations may occur because they may have a greater chance of survival or because it would benefit them in some way. For example, the giraffe's long neck came about when it found that it needed a way to obtain leaves from the tops of trees. And so, generation by generation, it's neck slowly lengthened until it was able to do so.

Since the natural selection is a theory, we can not apply a theory as a science. Even though some scientists believed in natural selection: think of Nazi scientists, Soviet scientists, etc. They were 100% evolutionist believers. Nobody yet seen atoms but we believe that they exist...strange. We apply faith in some modern science...hmmm...

The formation of new species, known as speciation, typically requires a reproductive barrier that prevents gene flow between populations. This can occur through mechanisms such as geographic isolation, genetic mutations, or behavioral differences. Over time, these barriers can lead to genetic divergence and the development of distinct species.

Yes, evolution is an ongoing process that continues to happen today. It is driven by various factors such as natural selection, genetic mutations, and other mechanisms that lead to changes in species over time.

Yes. Even though Darwin called the Origin " one long " argument " the book was well supported by the evidence of the day and gave ways to falsify the material in the book,. hypothesis for testing and predictions on what would be found that turned out to be quite accurate. So, scientific.

Basically because populations evolve and individuals are selected. Let us assume that a beneficial mutation occurs in a individual organism. Even if beneficial in the immediate environment it must be in the germ line and passed on to progeny who mate with other organisms whose genes must work in concert with the new mutation that then needs to spread far enough into the populations gene pool so that there is a change in allele frequency that leads to, perhaps, some morphological or behavioral change. This can take uncounted generations, or can be a bit quicker. But, never in one jump.

The variable in Daniel's planned experiment is the factor that he is changing or manipulating to see its effect on the outcome. It is the independent variable.

Darwin talked about natural selection, basically it means that the stronger ones survive to reproduce, if they develop an adaptation that works they pass it on. This relates to genes because that's how we pass down traits, so stronger ones are supposed to pass down better genes. and over a very long time a species evolves
