Why did horses evolve to be bigger?

Adapting and reacting to the changing environment, the then living horses changed too. They became larger (Mesohippus was about the size of a goat) and grew longer legs: they could run faster. The teeth became harder in reaction to the harder plant material (leaves) they had to eat.

Why do horses evolve?

The line leading from Eohippus to the modern horse exhibits the following evolutionary trends: increase in size, reduction in the number of hooves, loss of the footpads, lengthening of the legs, fusion of the independent bones of the lower legs, elongation of the muzzle, increase in the size and complexity of the brain …

How did horses evolve?

The evolution of the horse, a mammal of the family Equidae, occurred over a geologic time scale of 50 million years, transforming the small, dog-sized, forest-dwelling Eohippus into the modern horse. This means that horses share a common ancestry with tapirs and rhinoceroses.

Did horses used to be smaller?
