Eh?I thought the earth was entirely covered in ice at least a couple of times during the last few billion years?

That's the subject of scientific debateThe mainstream consensus is that there was always at least a band of ice-free land and ocean around the equator. But there are serious scientists who believe that a "Snowball Earth" did occur, on one or more occasions.

Yes,but the "snowball Earth" hypothesis refers to a period around half a billion to 650 million years ago, well before the evolution of complex life (or much life at all).
The Ice Ages, the last one of which ended only a few thousand years ago, were much, much less severe.
