Document Summary
Aristotle - believed that both inanimate objects and living species had fixed characteristics. Created ladder-like classification of nature from simplest to most complex: minerals to plants, plants to animals, animals to humans, humans to gods. 14th century - europeans merged biblical creationism with aristotle"s classification system. Believed that all different kinds of organisms had been created by god, and that species could not change, new species could not arise and none could go extinct. Natural theology - biological research that involved the naming and cataloguing of all creation, and then identifying its position and purpose in the scala naturae. 15th-18th century - biogeography, comparative morphology and geology promoted a growing awareness of change. George-louis leclerc, le comte de buffon - noted the existence of body parts with no apparent function. Buffon proposed that some animals must have changed since their creation, and that vestigial structures must have functioned in ancestral organisms. Species conceived by nature, and produced by time .
