This week the Natural Selection explored the frozen depths of the ice ages. Inspired by the frosty January weather, we looked at time periods when ice and snow extended far beyond the poles. We uncovered mammoth facts about megafauna and extinctions. Join us as we discuss snowball earth, our winter wardrobes, and (sort of) sabre-tooth cats. It would be brrrilliant if you shared the episode if you listened and enjoyed it!
