5. Factors in Evolution:
-
Mutation: Random changes in an organism’s DNA, providing a source of genetic variation.
-
Natural Selection: The process through which advantageous traits become more common in a population over time.
-
Genetic Drift: Random changes in allele frequencies within small populations due to chance events.
-
Gene Flow: The movement of genes between populations through migration or breeding.
-
Adaptation: The process by which organisms develop traits that enhance their fitness in a specific environment.
-
Extinction: The disappearance of a species from Earth, often due to environmental changes or competition.
