Thinking is a sign of oblivion. Only those who don't know must think and to resolve intelligence contained in "natural selection" they compare it with a combine sieve so they can hide behind the fact that combines don't think and still get the job done. Super intelligent! Evolution for dummies, and I love it. Right, lineages adapt because they don't have a mind to think until they fail to adapt and nature gets the best of them. Oh sorry, there is no best in nature because it has no mind. They just fail to reproduce their genes, oh sorry, they don't 'have' genes because they 'are' not but only their genes are. Each human being has hundreds of mutations and some have bigger ones to make humans out of a fish. Sounds like chaos to me. The thinking we do is just to eat, drink and be merry while in oblivion.
