Document Summary
Controversies with the origin of species publication schools; religion works, didn"t have a mechanism. Scopes [monkey] trial didn"t want to teach evolution in. Darwin was incorrect in the timing of ns, the way inheritance. Mechanism that drives evolution; variation in populations that is at least partly heritable allows for more successful varieties to increase in number, less successful ones to be eliminated. Ns is only partly a matter of survival; survival of the fittest was never actually said by darwin himself. Herbert spencer applied darwinian ideas to the concept of social engineering; promoted idea that minimal government intervention in human affairs is necessary used to support any socio-political position if you just put the right spin on it. Why fitness refers to reproductive success; the person with 5 kids is more fit in a darwinian sense than the one with 3 kids.
