Document Summary
Biology lecture 2 theory=body of knowledge known to be true, fact, overwhelming support and evidence for it. One of the most challenging and controversial aspects. Has no forethought, just an inevitable outcome, no greater plan. Threw out special creation and first to use the term evolution. Didn"t quite get it right, linear not branching(darwin came up with the tree) Mechanism is wrong because he thought the individual was changed by the environment and then pass along those changes. Wrong because we are born and die with the same genes, false because populations evolve not individuals. In giraffe pic, the giraffe is one individual, not multiple generations. Information can"t pass from the somatic cells to the gametes. Darwin co-discovered natural selection-the true mechanism of evolution at cambridge-darwin liked natural history. Got the job on the beagle as the ship"s naturalist returned from the beagle and accumulated evidence for 20 years so he would have plenty of evidence to back it up.
