Uh, actually, there is.
No, there really isn't.
The Miocene Epoch: 5.3 - 23.8 Million years ago (20 million years is roughly 1 million human generations)
The Miocene was a time of warmer global climates than those in the preceeding Oligocene, or the following Pliocene. It is particularly notable in that two major ecosystems first appeared at this time: kelp forests and grasslands. The expansion of grasslands is correlated to a drying of continental interiors as the global climate first warmed and then cooled. The largest animal life was characterized by Chalicotherium, a Miocene mammal from Kazakhstan. Chalicotherium was an unusual "odd-toed" hoofed mammal, or perissodactyl.

That's the point. If you could trace your ancestors back far enough, you'd find that they didn't look very human. Nothing to be embarrassed about. It happens in the best of families.
