Document Summary

Major events in the history of biology: darwinian thought. Scala naturae: living organisms arrive to the planet at once on oct 23rd, 4004 bce, with no change (predarwinian biology) Georges-louis leclerc, comte de bufon (1707-1788): beginning of biogeography. First scienist come up with idea that there are variaion around the world. Noices animals that have similar basic appearance. Physical expression of the essence changes because of environmental factors. Proposes that the earth started of as a molten mass that cooled. Thinks that n and s poles represents the irst habitable locaions -> cooler. All living forms appeared on earth with an unique essence. As the earth cooled, the equatorial regions were the last to be habitable. Organisms moved from the poles towards the equator. In the new environments, their essence was expressed as modiied morphologies. Proposes the earth is 70,000 years old, not 6,000 (predarwinian) Concept of essenialism remains intact, but allows for modiicaion and changing diversity over ime.
