Summary

At long last, a plant episode! Our friend Aly Baumgartner joins the podcast to teach us all about grass - it's not just part of the background! From humble beginnings during the Age of Reptiles, grasses have gone on to dominate global ecosystems (as well as human diet!) and continue to do so today. They are truly one of the most influential groups of life on Earth. In the news: strange ancient reef fish, dinosaur tongues, a surprise extinct gibbon, and a history of primate claws.
