Cloven hooves are a common trait among many animals, including cows, pigs, and deer. The hooves are split into two parts, each with its own claw. This allows the animal to better grip the ground when walking or running. There are a few theories as to how cloven hooves evolved. One is that they provide better traction on slippery or uneven surfaces. Another is that they help animals move more quietly through forests and brush. Whatever the reason, cloven hooves are an adaptation that has helped many animals thrive in their environments.
