Study Notes
Natural Selection
- Involves the survival and reproduction of individuals with favorable traits, leading to a change in the genetic makeup of a population over time
When Does Natural Selection Occur?
- Natural selection occurs when individuals with favorable traits are more likely to survive and reproduce, passing those traits to their offspring
Mechanisms of Natural Selection
- Mutation, genetic drift, gene flow, and genetic hitchhiking are mechanisms of natural selection
- NOT a mechanism of natural selection: use of antibiotics to kill bacteria
Macroevolution and Microevolution
- Macroevolution: the process of major evolutionary changes that occur over long periods of time, resulting in the formation of new species
- Microevolution: the process of small-scale evolutionary changes that occur within a population over a relatively short period of time
Population Genetics
- The study of how gene frequencies change in frequency over time within a population
- Focuses on the genetic variation within and between populations of the same species
- By studying population genetics, scientists can gain insights into the processes that drive evolutionary change and evolution
