They made an interesting point on the whole "water ape" theory. Is it that far fetched to think that a species of our ancestors branched off into the water and stayed there? It's not so unbelievable when you take into account that the killer whale has wolf ancestors on land. They also brought up a cool fact that we can see today. The Polar bear was in the grizzly family. It branched off and slowly has adapted to it's environment (webbed front claws etc...) they say that eventually, the Polar bear will convert to the water completely. Pretty cool stuff. Anyone know of any more examples?
