In this episode of Talk Nerdy, Cara is joined by paleontologist Dr. Elsa Panciroli to talk about her book, "Beasts Before Us: The Untold Story of Mammal Origins and Evolution." They discuss how many of us have our timelines all wrong, as mammals have been evolving since far before the asteroid impact that rendered the dinosaurs extinct. Follow Elsa: @gsciencelady.
