Darwinian evolution can explain the selection of the mutation but it cannot explain the arrival of the mutation.
The arrival of the mutation? Mutations happen quite frequently in the animal kingdom anyway.
Did you never do the fruitfly experiment in 10'th grade biology? In just a few weeks you can observe many mutated specimens produced from a population contained within a quart mason jar.
Modern man contains many genes which simply can not be found in remains from hominid populations of 100,000 years ago. The source of those genes is mutations. Populations which migrated out of Africa carry many genes which are not found in the peoples left behind. If it were not for mutations acquired by different human populations at different times in history, "23 and Me" would have no way to determine the source of our ancestry. We would all still be carrying the same genes we left Africa with.
Human population is still evolving. We are selectively breeding humans for low intelligence and low motivation.
No? What are the fastest growing populations across the world? Hint, of the top twenty only Iraq lies north of Egypt. China and India no longer make the cut of the top twenty in % rate of population increase.
Even in America, which populations are growing fastest? Hint again? It is not College Professors, Bank Managers, Captains of Industry, or those holding advanced Engineering degrees.
People who choose to brew up their own storms bitch loudest about the rain.
