How do experiments with selective breeding help explain natural selection?

Experiments with selective breeding illustrate the principles of natural selection by demonstrating how specific traits can be enhanced or diminished in a population over generations based on human choice. In selective breeding, individuals with desirable characteristics are chosen to reproduce, leading to a concentration of those traits in subsequent generations. This mirrors natural selection, where environmental pressures favor certain traits, allowing individuals best suited to their environment to survive and reproduce. Both processes show how variations within a species can lead to evolutionary changes over time.
