What is the horse series, and is it truly a series?
Many (possibly most) biology text-books present a sequence of very small horses (about dog sized) evolve up into modern large horses. However, paleontologist & evolutionist, Niles Eldredge, states that the sequence is entirely speculative, even though it is commonly presented as literal truth in biology textbooks. Apparently in recognition of this fact, the American Museum of Natural History has had to rearrange its “liner horse sequence” exhibit, to try to reduce miscommunicating to the public.
