Tongues are a common feature among tetrapod animals, but the evolution of this organ is complex and fascinating. Through time, tongues have evolved a wide variety of functions from feeding to sensing to speech. This episode, we\u2019ll explore the diversity of tongues and their bony counterparts in the hyoid apparatus, we\u2019ll examine what\u2019s known about tongue evolution, and we\u2019ll discuss how fossils \u2013 especially hyoids \u2013 help us interpret the tongues of extinct species.\nIn the news: dinosaur temperatures, ancient geomagnetism, Martian lake conditions, and splitting sea stars.\nTime markers:Intro & Announcements: 00:00:00News: 00:08:15Main discussion, Part 1: 00:39:55Main discussion, Part 2: 01:24:05Patron question: 02:02:40\nCheck out our website for this episode\u2019s blog post and more: http://commondescentpodcast.com/\nJoin us on Patreon to support the podcast and enjoy bonus content: https://www.patreon.com/commondescentpodcast\nGot a topic you want to hear about?
