As the earliest farmers began to select wild plants and animals that had desirable traits, they initiated a series of genetic changes in these species that gradually made them more suitable for agriculture. Plants became easier to grow, had greater yields, and were of higher quality. Animal species exhibited favorable changes in behavior, coat color, and reproductive traits. Barbara Schaal discussed how the artificial selection of these species—a pivotal technological achievement—has influenced their genetics, evolution, and capacity to flourish in the care of humans.
