the theory that genetic mutation and natural selection over time leads to speciation.
simple enough for you?
That's enough. So you believe that The Theory of Evolution reads: Evolution is caused by genetic mutation and natural selection? In what order? In what way? And what other sort of mutation is there? Why use the word, genetic?
Might you mean, rather: evolution is caused by natural selection of mutation?
I wonder, if that's suitable, if the idea of a population comes into play at some point? or are we just talking a couple of thoroughbreds and stud fees, here? Or is that really included in your sense of natural selection, itself, and so redundant in your opinion, when stating just what you believe might be causing this evolution?
