The world is a different place in the dark, and a whole array of organisms have adapted to being most active outside of daytime hours. This episode, we’ll explore the regular traits that allow nocturnal animals to get by, we’ll discuss some of the ways nocturnal evolution has shaped living species, and we’ll investigate which – if any – of these traits we can identify in the fossil record. In the news: snake hormones, Australian amphibians, ancient microbes, and baby dinosaurs.
