The Variation of Animals and Plants Under Domestication

"The Variation of Animals and Plants Under Domestication" by Charles Darwin explores how humans have selectively bred plants and animals, leading to significant genetic differences from their wild ancestors. Through controlled breeding, certain traits—like size, temperament, or yield—are emphasized, causing variations over generations. Darwin shows that domestication involves natural selection within human preferences, resulting in diverse breeds and varieties. This process demonstrates how species can change dramatically in response to human influence, highlighting the dynamic relationship between humans and the organisms they cultivate.
