the first born one-toed horse was named - Plehippus
The first single toed species is the sloth
The first horse showed up on the sixth day of the creation week. The above answer is a biblical answer. If you are looking for a scientific answer then the horse has existed in one form or another for roughly 65 million years. However the first single toed horse appeared 4 million years ago when Equus had fully evolved from the its primative multi-toed ancestors.
Horses decended from a small 3 toed animal. But the first and oldest actual breed was the Arabian.
A tiny, four toed animal called Eohippus, latin for "Dawn Horse". No bigger than a small dog.
Pigeon toed I think that question is from howrse, I am on it! Thumper1999
Cows have a double- toed hoof, where the hoof is split into two, not united as one like a horse's. All wild herbivorous animals are double-toed; it is only those relative to the horse like donkeys that only have the single "toed" hoof.
Horses are one toed animals. They have one toe on each foot (which is there hoof) and one thumb (which is a chestnut, a bone lump that is half way up there leg).
This question cannot be answered since there is no known time when the first horse was born.
Horses evolved over 55 million years of time. They began as Eohippus which had multiple toes and browsed on leaves in forests. Once the forests began to give way to grasslands the horse began to slowly lose use of it's outer toes and the center toe became bigger and stronger. Finally the first one toed horse appeared and gave rise to the modern horse.
There are no such thing as 3 toe horses. God made horses as they are now.
These animals are classified as "odd-toed ungulates," or "Perissidactyla." The "toes" are actually called "claws." Odd-toed ungulates include the horse, rhinoceros, tapir, zebra, donkey, and onager.
The differents is that the normal one has two toes and three toed one has three toes.
