From Darwin to Dolly, domesticated livestock have guided our understanding of evolution and biology. Moreover, for the past 10,000 years, livestock have provided sustenance to humans with their hides, hair, meat, milk, strength, speed, and companionship. Now, livestock are poised to give us even more, thanks to new insights from genomics and molecular phylogenetics. Five articles in this issue deal with the biogeography of domestication (1, 2), the development of modern breeds (1, 3), the genes responsible for agriculturally important traits (3, 4), and the potential use of livestock species as models for human diseases (5).
