Summary

None of us are alone. Like, in the literal, biological sense. Symbiotic relationships – close interactions between unrelated organisms – are a defining feature of life on Earth. Each of our bodies has its own share of parasites, hitchhikers, and tiny helpers, and some of the most prominent ecosystems on Earth function only by virtue of the symbiotic relationships at their foundations. In this episode, we touch on the incredible diversity and impact of symbiosis, and how the deep history of these relationships has created the world we know today. In the news: sick sauropods, puking pterosaurs, jumping genes in snakes, and dino-eating crocs.
