SciShow: 4 Animals That Don’t Have Resident Gut Microbiomes

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: We humans couldn’t live without our gut microbes, but not all animals rely on microscopic digestive communities like we do. And understanding why these animals ditched their microbial partners can teach us a lot about the costs and benefits of making evolutionary friends.
