Microevolution

Mr. Anderson explains microevolution, focusing on changes in allele frequency within a gene pool. He contrasts it with macroevolution and discusses five causes of microevolution: small sample size, non-random mating, mutation, gene flow, and natural selection. Each cause is illustrated with examples, such as genetic drift, inbreeding, mutations like sickle cell anemia, migration patterns, and natural selection in bacteria. The podcast emphasizes understanding these processes to grasp how populations evolve over time.
