Boas and pythons include some of the most famous snake species on Earth, renowned for their incredible tropical diversity, their often beautiful scale patterns, and their often impressive size. This episode, we discuss what sets these two lineages apart from other snakes – and each other – and we explore the evolutionary path recorded in their fossil record. In the news: giant early tetrapods, digging dinosaurs, coastal croc-cousins, and striking snakes.
