Document Summary
Lecture 2 - history of evolutionary theory and background biology. January 14, 2013: hypothesis started in arab and greek areas, and then moved to england, lyell is the father of geology. He didn"t create the ideas, but rather summarized and revised them: history of evolutionary theory, evolution, a change in the genetic structure of a population from one generation to the next. Not catastrophism which states changes in the earth are due to sudden violent random events: lyell observed that earth is millions of years old. At that time, everyone thought it was only some thousands of years old. This was a very radical idea at that time, because humans were known as superior and were always acknowledged as separate. He thought an organism could acquire characteristics in its lifetime: darwin-wallace was the first to mention that evolutionary change happens by natural selection, which states that evolution requires that variation already exists.
