Document Summary
Levels of evolutionary analysis: general evolutionary theory, middle-level evolutionary theories, specific evolutionary hypotheses. Origins of human nature: there are three theories: creationism which is a supreme being of some sort created all of life on this planet. It has not been proved useful by science: seeding means that life did not originate on earth. The seeds of life arrived earth via a meteorite. Random mutations cause an adaptation to occur. Environment can turn on and turn off certain genes. Adaptation can only survive if it proves beneficial to the species. To qualify as an adaptation, it has to emerge at a particular time in the organism"s life, Adaptations do not have to appear at birth, they can come from a lot of different areas: environment interacting, an event, from birth, there has to be some categorical change in the genetic structure. Those features that are not beneficial are going to be passed.
