• Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring. It is not driven by human intervention.
• Genetic drift is a change in the frequency of an allele within a population due to random sampling of organisms.
• Artificial selection is when humans deliberately breed plants or animals for specific traits.
