And what's unique about this jump is they went from four to three toes.
So, this is where we start seeing evidence of
that, that fourth digit disappearing and going up the leg
on those earlier equids are, well they're really not equids
at this point, the earlier species from eohippus to mesohippus.
And you can see there are not that
much taller, so they're getting a little bit taller,
but what's also interesting about this is they
went from three grinding teeth to six grinding teeth.
So, obviously some, there are some dietary changes driving this evolution, where,
you know, they kind evolve more of a, as they, they evolved
a more grass based diet, their teeth changed with them so they
can handle that eating constant grass, grinding it down and eating it.
So, so from that browse diet to more of a grazing diet.
Now we're going to jump ahead, you know, pretty far again and
this is where we get to dinohippus, which is where we
start seeing evidence of a single-toed horse, you know, they go
on from those three toes to that one toe or one hoof.
So that's where we start to see first evidence.
And this is about 12 million years ago.
