Summary of Darwin’s Theory
•These differences made the finches/tortoises better adapted to take advantage of the food in their particular local environment
•The traits that help an organism survive in a particular environment are “selected” in natural selection
•Overtime, natural selection results in changes in the inherited characteristics of a population. These changes increase a species fitness (survival rate)
•Species alive today are descended with modifications from common ancestors
•Darwin believed that evolution is a slow process and it might be too slow to observe within a human life
