“This is an artist’s reconstruction of Sifrhippus sandrae (right) touching noses with a modern Morgan horse (left) that stands about 5 feet high at the shoulders and weighs about 1,000 pounds. Sifrhippus was the size of a small house cat (about 8.5 pounds) at the beginning of the Eocene (approximately 55.8 million years ago) and is the earliest known horse.

“This is a way too-cool cool illustration reflecting the evolution of horses from the small, three-toed, equines of 56 million years ago to the massive one-toed animals we know and love today. Unlike the diversity of human induced selection in dogs, the horse is entirely the product of selection through the utterly fish-eyed indifference of nature; a change similar in scope to the changes seen between cabbages and Brussels sprouts, though not so radical as the change between the native little tar weed of coastal California and the majestic silver swords found on the volcanic mountains of Hawaii.”
