How have horses evolved over the years?
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 …
What did horses used to look like?
It was an animal approximately the size of a fox (250–450 mm in height), with a relatively short head and neck and a springy, arched back.

Where did horses originally evolved?
Horses originated in North America 35-56 million years ago. These terrier-sized mammals were adapted to forest life. Over millions of years, they increased in size and diversified. Horses got larger in size and underwent other changes to their feet and teeth to adapt to changing environments.
Did cavemen ride horses?
Although horses appeared in Paleolithic cave art as early as 30,000 BCE, these were wild horses and were probably hunted for meat. The clearest evidence of early use of the horse as a means of transport is from chariot burials dated c. 2000 BCE.
What species in the fossil record have similar structures to horses?
The horse belongs to the order Perissodactyla (odd-toed ungulates), the members of which all share hoofed feet and an odd number of toes on each foot, as well as mobile upper lips and a similar tooth structure. This means that horses share a common ancestry with tapirs and rhinoceroses.
Why did horses evolve so big?
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.
