Summary

Marsupials are like alternate-reality mammals. Everything about them, from their skeletons to their reproductive strategies, is just a bit strange – from the perspective of us placental mammals, that is! But you can’t argue with results, and marsupials include some of the most fascinating mammals of the past and present. In this episode, we track the long evolutionary journey that gave the modern world its kangaroos, koalas, possums, opossums, and more. In the news: air-breathing sea scorpions, fish bone evolution, mastodon migrations, and burrowing dinosaurs.
