40 Million Year Old Primate Fossils Found In Asia 91
sosaited writes "It has been widely believed that our ancestors originated out of Africa, but a paper published in Nature by Carnegie Museum of Natural History scientists puts this in doubt. The paper is based on the fossils of four primate species found in Asia which are 40 million years old, during which period Africa was thought to not have these species. The diversity and timing of the new anthropoids raises two scenarios. Anthropoids might simply have emerged in Africa much earlier than thought, and gone undiscovered by modern paleontologists. Or they could have crossed over from Asia, where evidence suggests that anthropoids lived 55 million years ago, flourishing and diversifying in the wide-open ecological niches of an anthropoid-free Africa."

You might want to check your phrasing. Saying that the polar ice caps are "not supposed to be there" is nonsensical. How did they get there? Did god spilled a glass of ice water? I think the point you're trying to make is: There was a time when the polar ice caps didn't exists, and primates still managed to survive (evidently). Sorry to nitpick.
