Document Summary
Le comte de buffon- trying to classify species. But he thought they changed over time (evolution) Transformational theory of evolution (this theory had been proven wrong) Species evolve to better fit their environment. Continual use and disuse of parts- general change eventually in that species. Cut of the tails of rats- nothing happened. This proved lamarcks theory of evolution as false. Species were created at some point and there were no changes in species. Catastrophism- catastrophic events that would wipe out a species and new species similar would form (e. g. flood) Uniformitarianism- natural agents currently at work and throughout history (geologic thought) Evolution by natural selection: species change gradually through time due to interactions between individuals and their environment.
