In addition to observing natural selection in domestic plant and animals, Darwin describes other sup-properties of evolution that he goes into much greater detail in subsequent chapters. How "variations manifestly useful or pleasing to man appear only occasionally ... less perfectly developed or from indolent habit" (Darwin 137). This led to 200 out 550 species to not fly.
