This shows people have absolutely no idea how evolution and genetics works.
I don't even know where to start to explain it.
1. You've heard of survival of the fittest no? The traits most adaptive for survival in an environment gets passed on to the next generation and those that aren't die off.
2. Examples of this concept at work= Divergent evolution....start as one species, get separated physically into 2 different environments. In each group traits are selected for that are ideal for survival in each environment and after many generations you have 2 new species.
3. Evolution is a very slow process and takes thousands of generations to create new species. What you said is insinuating that evolution happens overnight.
4. An example of a quicker form of evolution...because microbes have a very short life cycles evidence of genetic shift is easy to demonstrate.
eg. acquiring antibiotic resistance. Microbes and humans are in a constant war of arms, and their way of dealing with out drugs is by acquiring new genes + mutations. (The Red Queen hypothesis)
Cliffnotes:
-Evolution is genetic change as a result of environmental change/stressors
-evolution doesn't happen overnight
-In some species with short life cycles the concepts that govern evolution can be established more rapidly.
