Question

what species of horse is older - Pliohippus or Mesohippus?

Answer 1

Answer:

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,[1] forest-dwelling Eohippus into the modern horse. Paleozoologists have been able to piece together a more complete outline of the evolutionary lineage of the modern horse than of any other animal. Much of this evolution took place in North America, where horses originated but became extinct about 10,000 years ago

Answer 2

Answer:

the answer should be Pliohippus
