Why do cows and deer have two-toed hooves?

Video · 1:45 · Crafty Clover explains, from A Million Whys Book 33

Cows, deer, and goats each walk on two toes on each foot, and each toe has its own hoof, so the foot looks split. Split hooves can spread apart to grip mud, snow, and rocky ground. The two toes also help the animal keep its balance on uneven ground. It is a sturdy design for a plant-eater who spends all day on its feet.
