My brain hurts....
Actually, I didn't realize that there was any doubt involved. I don't follow closely, but on my last reading the conclusions were that horses were descent from the "Eohippus".
Now in doing some quick research, I've run across a site stating in detail why the evolution of the horse, as stated in previous text, is a fraud. Take it for what it's worth I suppose.
Interesting either way. The Eohippus was said to make it's appearance some 55 million years ago. 50 different subspecies existing some 11,000 year ago isn't such a surprise to me. I don't see their evolution as being limited to a single line resulting in our modern horses. It could have been a series of experiments in design arriving at our present day species. Many people believe the same of early man, who may have faced competition from co-existing with several other man-like species. Even cro-magnon man may have had encounters with the neandertal. So it's not such a leap of imagination to believe in 50 different subspecies of horse.
Of course, more detail would be useful. Yet my coffee is done and my addiction is compelling me to leave my fellow FReepers with the Monty Python GIF, then make a quick exit.
Cool post. Thanks!
I wish I had me one of them three-toed horses. It would save a fortune on farrier's bills.
