Our genetic resemblances, and some times the lack of them, to our 
ancestors suggest some kind of genetic adaptation to the environment (or 
so the theories stated). The problem is, if we really did adjust to the 
environment, how did it happen? Aside from rare radiation, how can 
behaviour and the environment change our biochemistry, and leave the next 
generation more fitting for the same conditions?
