The Classic Omnivore
Human beings seem to be classic omnivores. Originally living as "hunter-gatherers", we hunted and fished when possible but also gathered nuts, berries, fruits, seeds, and roots for much of our diet. We're physically well suited for both tasks; our hands are perfect for picking things, and our build is ideal for running down even the fastest game animals because of our great stamina. Some 10,000 years ago humans began practicing agriculture involving both animals and plants. The other omnivorous mammals include chimpanzees, pigs, opossums, porcupines, bears, raccoons, chipmunks, mice and rats, and skunks. But even many mammals classed as carnivorous turn out to be capable of shifting to plant foods when necessary.
