Document Summary

Bio 180: chapter 22. 3: process of evolution: how does natural selection. Darwin didn"t recognize evolution, he found a way in which descent with modification could be explained. He spent a lot of time looking at the variation in plants and animals. He also had a wealth of data from his geologist friend charles lyell. He had strong foundation in the pattern of evolution. To understand the process of evolution, darwin turned to pigeon breeding. He chose certain individuals with particular traits and saw how they passed on to progeny. He manipulated the composition of the population, which is called artificial selection. Around that time, malthus"s studies on the human struggle for survival came out. The book is specifically called an essay on the principle of population. : studied populations in england and other european countries, he proposed that the exponentially growing population would compete for food and places to live.
