Which of the following is a mechanism of microevolution? (2005)

Step 1: Understand what microevolution means. Microevolution refers to small changes in a population's genetic makeup over time.
Step 2: Identify the mechanisms of microevolution. The main mechanisms are natural selection, gene flow, and genetic drift.
Step 3: Recognize that natural selection is the process where individuals with favorable traits are more likely to survive and reproduce.
Step 4: Understand gene flow, which is the movement of genes between populations, often through migration.
Step 5: Learn about genetic drift, which is the random change in allele frequencies in a population, especially in small populations.
Step 6: Conclude that all the options listed (natural selection, gene flow, and genetic drift) are indeed mechanisms of microevolution.
