Question

Horses evolved teeth with a cement covering and evolved from multiple toes to a single hoof because:

A. their diet changed from plants and meat, to just plants.
B. horses have always been the same.
C. their environment changed from forest to grassland as the forests shrank.
D. they became hunted by humans and evolved advantages to run faster.

Answer 1

The answer is C because horses used to have many smaller toes, perfect for running on softer forest ground. As the environment changed and they ran on grasslands, they evolved a single “toe” (their hoof) to run on providing better resistance to hard ground.
