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!
Now why would professional scientists do such a thing???
Never mind. I know.
Gotta prove something.....
As the Great Ice Age came to an end, some 11,000 years ago, North America was thought to be home to as many as 50 species and subspecies of horse. But studies of ancient DNA tell a rather different story, suggesting the horses belonged to just two species... The caballines are thought to be the ancestors of today's domestic horse... The Oxford research suggests that the stilt-legged horse, which was thought to have migrated into North America from Asia, at a time when the continents were linked by a land bridge, appears, in fact, to be native to North America.Fascinating that the horse appears to be native to North America. I believe the same used to be said of the wolf and all domesticated dogs. I doubt that these findings will catch on. I would like to think that they would lead to the demise of mtDNA GIGO.
Mitochondria, the powerpacks of the cell, have their own DNA and are inherited along the maternal line. Their DNA mutates at a stable rate...Heh... Please ping me, if you see articles appropriate for GGG ping.

I wasn't aware that anyone thought otherwise.
Creationist horses say that they aren't related to these earlier horses and say it's a fraud.
