Any man, in the right situation, is capable of murder. But not any man is capable of being a good camper. So, murder and camping are not as similar as you might think
That doesn\'t explain anything, that wasn\'t evolution, adaptation maybe. Plus there has never been a recorded mutation that had a positive effect, ie. something that wouldn\'t kill/harm you. Your dna can only degrade, like a photocopy can\'t be better than the original, without tampering with it anyway.
