Eohippus different to the modern day horse?

Eohippus, often referred to as the "dawn horse," lived around 55 million years ago and differs significantly from modern horses in several ways. It was much smaller, about the size of a dog, and had a more primitive, flexible body structure with multiple toes—specifically, four toes on its front feet and three on its hind feet. Eohippus also had a diet that consisted mainly of soft, leafy vegetation, whereas modern horses are adapted for grazing on tougher grasses. Over millions of years, evolution led to the development of larger size, single-toed hooves, and adaptations for a more varied diet in modern horses.
