Were mammals once reptile-like? When did 'mammalness' begin? What are the origins of hair, lactation and warm-bloodedness?
It all began with a group of animals called the SYNAPSIDS.
JULIEN BENOIT is a paleontologist based at the Evolutionary Studies Institute, University of the Witwatersrand. His research explores the origins of mammals, going right back to the Permian, over three hundred million years ago.
MARK from Evolution Soup takes a deep dive with Julien into the world of pelycosaurs, therapsids, and cynodonts - the ancient cousins of all mammals (including ourselves).
* Any reference to early synapsids being 'reptiles' in this presentation is basically shorthand for reptile-like. This is a complex story and we want it to be accessible to the curious as well as to academics. 🙂
