Document Summary
The main -valid- point is that genetic factors interact with environment factors and cannot be considered separate from each other. Evolution is the change or creation of a new species over the course of time. Change refers to a change in the genetic code or the allelic frequencies in a population. Changes can be subtle changes or be variable. Natural selection is the mechanism through which evolution takes place. Darwin"s journey on the beagle (1831-36) to the galapagos islands. Looked at finches, they looked different, had different behaviour based on which island they were on. They were perfectly suited for the island they were living on. Lyell"s book on the principles of geology. Talked about how small changes of long periods of times can produce huge effects. Darwin said that this change could apply to humans and to species. Malthus"s essay on the principle of population. Talking about cities and the fight for survival.
