Ten years prior to Darwin's book a creationist wrote about adaptation. Coming off the ark was the horse kind, the deer kind, the elephant kind, cat kind and all the kinds that originated the animals we now see.
So there was one species of equine, and it became at least the three that remain today, yes? Ok, so how? By what process? Families aren't species. They are one category up from species, since they cannot produce fertile offspring cross-species. So lets go one more category up from there, to Perissodactyla, the order to which equine belongs. Are all members of Perissodactyla also a mere diversification of the original created species? How'd we get all the horses, the two or three types of rhinoceros, and tapirs from that? What was the process?
