A baseball outfielder does not calculate where a fly ball will land. They simply run while keeping their line of sight to the ball at a constant angle. Falcons hunting ducks use the same method. This instinctive tracking is called the gaze heuristic.
Newborn horses don't have hard hooves. A jelly-like covering called "foal slippers" wraps around their hooves, protecting the mother during pregnancy and birth. These coverings naturally fall off once the foal begins to stand and walk.
Walking with same-side arm and leg moving together (lateral walk) is actually the most common gait among mammals — dogs, cats, elephants, and deer all walk this way. In Edo-period Japan, people also walked this way, using a style called "nanba."
