Just adding a sidenote:
The idea that evolution can "make my brain better evolved than your brain", ect, is a very dangerous idea.
Hitler used survival of the fitest to justify genocide.
The idea that African Americans are 'under evolved' humans has been taught in the past.
If we are animals we have no rules.
one of the Columbine shooters had a t-shirt saying "survival of the fitest" on it.
Several other school shooters have made active refferences to natural selection, or survival of the fittest.
And the list could, (and I might make a longer one later) go on.
biology : a theory that the differences between modern plants and animals are because of changes that happened by a natural process over a very long time
: the process by which changes in plants and animals happen over time
: a process of slow change and development
