• Episode 232 - Vertebrate Origins

  Today, bony animals are some of the most diverse organisms on Earth, but it wasn’t always that way. This episode, we explore what features distinguish vertebrates from their closest relatives, and we dive into the abundant evidence from genetics, embryology, and the fossil record that gives us a glimpse at how our distant ancestors came to be. In the news: swimming hands, early life, Dunkleosteus jaws, and Neanderthal noses Time markers: Intro & Announcements: 00:00:00 News: 00:05:35 Main discussion, Part 1: 00:42:55 Main discussion, Part 2: 01:21:55 Patron question: 02:05:55 Check out our website for this episode’s blog post and more: http://commondescentpodcast.com/ Join us on Patreon to support the podcast and enjoy bonus content: https://www.patreon.com/commondescentpodcast Got a topic you want to hear about?

• Episode 231 - Back to the Water (Secondarily Aquatic Vertebrates)

  Nearly 400 million years ago, an unusual group of fish gave rise to the first land-dwelling vertebrates. Since then, their descendants have repeatedly moved back into the water. This episode, we explore the many ways these species adapt to the challenges of turning a terrestrial body into one that can survive at sea, and we investigate some of the most famous and confusing cases from the fossil record. In the news: post-extinction oceans, croc eggs, damaged dino tails, and meat-eating dung beetles.

• Episode 230 - Pachycephalosaurs

  The dome-headed dinosaurs are some of the most iconic ancient reptiles, but they’re surprisingly unexplored compared to other dinos. This episode, we explore what makes these dinosaurs unique, what limits our understanding of them, and the many confounding mysteries that paleontologists have been scratching their heads over, including the question of what exactly they were doing with those thick heads. In the news: the I Know Dino children’s book, giant reptile locomotion, and dinosaur hooves.

• Cute-E – Pikmin

  Welcome … to Cute-E! During our Spook-E series, we speculate on the evolution of monsters from myth and popular media, but we leave out fiction’s more adorable creatures. In Cute-E, we choose cuddlier critters and discuss how they – or something like them – could evolve here on Earth, pulling inspiration from real-world species across our planet’s history. This year’s theme is Monsters of Nintendo. This episode, we pluck precious partners from the soil. What could be the evolutionary background of tiny and colorful workers that blend the features of plants and animals? Our creatures to create this time: Pikmin.
