What did Charles Darwin discover as a result of his experiments with breeding pigeons?

Charles Darwin discovered that selective breeding could lead to significant changes in traits within a species over relatively short periods. His experiments with pigeons demonstrated how specific characteristics, such as size, color, and feather type, could be amplified by choosing which individuals to breed. This observation supported his broader theory of natural selection, illustrating how variation within species could lead to the evolution of new forms over time. Ultimately, it highlighted the role of human intervention in shaping traits, paralleling natural processes in the wild.
