Module 3 Introduction: (U4 M3) Process of Evolution
This Module focuses on how evolution occurs, in terms of microevolution, the change in allele frequencies that occur over time in a population. This Module relies heavily on your understanding of genetics and takes it one step further to look at population genetics. You will learn about how processes such as genetic drift, mutations, and sexual selection drive the changes in populations over time and can eventually result in the development of genetically unique species.
Describe the criteria by which organisms are classified into different species, reproductive barriers that separate species, and the processes that are thought to lead to the formation of a new species.
- Describe the theory of evolution in terms of variation and natural selection within populations, the circumstances under which evolution occurs, and how evolution explains biological diversity and adaptation. (Why does a beaver have a flat tail and webbed feet?)
