b'None of us are alone. Like, in the literal, biological sense. Symbiotic relationships \\u2013 close interactions between unrelated organisms \\u2013 are a defining feature of life on Earth. Each of our bodies has its own share of parasites, hitchhikers, and tiny helpers, and some of the most prominent ecosystems on Earth function only by virtue of the symbiotic relationships at their foundations. In this episode, we touch on the incredible diversity and impact of symbiosis, and how the deep history of these relationships has created the world we know today.\\nIn the news: sick sauropods, puking pterosaurs, jumping genes in snakes, and dino-eating crocs.\\nTime markers:Intro & Announcements: 00:00:00News: 00:05:00Main discussion, Part 1: 00:39:30Main discussion, Part 2: 01:24:30Patron question: 02:05:30\\nCheck out our blog for bonus info and pictures:http://commondescentpodcast.wordpress.com/\\nJoin us on Patreon to support the podcast and enjoy bonus content! https://www.patreon.com/commondescentpodcast\\xa0\\nOr make a one-time donation via PayPal: https://tinyurl.com/4c68u4hp\\nFind merch at the Common Descent Store! http://zazzle.com/common_descent\\nJoin the Common Descent Discord server! https://discord.gg/CwPBxdh9Ev\\nFollow and Support us on: Twitter: https://twitter.com/CommonDescentPCFacebook: https://www.facebook.com/commondescentpodcastInstagram: @commondescentpodcast YouTube: https://www.youtube.com/channel/UCePRXHEnZmTGum2r1l2mduwPodBean: https://commondescentpodcast.podbean.com/ iTunes: https://itunes.apple.com/us/podcast/the-common-descent-podcast/id1207586509?mt=2\\nYou can email us at commondescentpodcast(at)gmail.comOr send us physical mail at:The Common Descent Podcast1735 W State of Franklin Rd.
