Study Notes
Evolution by Natural Selection
- Charles Darwin conceived the theory of evolution by natural selection.
Definition of Evolution
- Evolution is the change in the inherited characteristics of a population of organisms over time.
Processes of Evolution
- Genetic variation is acted upon by the following processes to cause evolution:
- Mutation
- Gene flow
- Genetic drift
- Natural selection
Consequences of Evolution
- The process of evolution has given rise to diversity at every level of biological organization, including:
- Molecules
- Cells
- Organisms
- Populations
- Species
- Ecosystems
Evidence for Evolution
- The following observable facts establish evolution by natural selection:
- The fossil record
- Comparative anatomy and embryology
- Molecular biology
- Biogeography
- Observable evolutionary changes in natural populations
