Document Summary

Gradual change of populations or organisms over time (time = generations) Changes over the lifetime of one individual is not evolution (e. g. aging process or changing of behaviour) Study of organismal form and variety in natural environments. Merge with biblical accounts natural theology: taxonomy linnaeus (1700s) Three disciplines that contributed to the history of evolutionary theory: biogeography, comparative morphology, geology. All promoted awareness of change: biogeography, world distribution of organisms, how does the changes in the earth"s geography relate to changes in species distribution, global exploration raised difficult questions for unchanging creation, comparative morphology. Buffon leclerc (1700s: currently useless structures - vestigial structures, changed since creation. But how: proposed: conceived by nature and produced by time, geology. Organisms that lived at successive times in the past: catastrophism. Each fossil layer organisms that died in a local catastrophe. Slow and continuous physical changes over long periods of time caused earth"s geological features.
