Document Summary

2. 1 history of evolutionary theory: the only thing that was constant was change. Variation within species: a lot more variety in the world linnaeus called them morph-opines. Incredible variations: there are greater range of insects than any plants or animals; world is far more complex than for those in past centuries. Linnaeus (1701-1778): taxonomy and binomial nomenclature; believed in fixated species but acknowledged the similarities between humans and great apes. George buffon (1707-1788): species adapt slightly to new conditions . Charles darwin (1809-1882): grew up in household where evolution was talked about but focussed on a biblical framework due to school; he was wealthy and free to do whatever he wanted. Joined the voyage of the beagle (1832-1836): went around the world to fill in gaps in maps. Each finch/tortoise type had ecologically different niches based on which island they are from.
