Podcast 190 - Arthropod Evo Devo

The gang discusses two papers about arthropod evolution and development. One paper focuses on the evolution of arthropod segmentation, and the other summarizes research on the development of the insect wing. Meanwhile, Amanda has a beer with no unintended consequences, Curt makes a shocking discovery about marketing, and James goes from 0 to professional in milliseconds. As we did last time, here are some organizations you can donate to: https://blacklivesmatter.com/ https://bailproject.org/ https://www.aclu.org/   Up-Goer Five (Amanda Edition):  Today our friends look at small things with many legs and many body parts. The first paper is looking at how these small things with many legs and many body parts first grew the parts they needed to fly. The paper says lots of words about this, but there are two big ideas, saying that these body parts that the body parts these animals needed to fly grew from either the up on the side or down on the side. It turns out that maybe the truth is somewhere in the middle. No, really, they probably grew from both up and down on the side, there was another paper that came out while this one was being worked on that says that, and they talk about it in this paper. The second paper looks at how these animals came to have many body parts, and says how it is important that we look at the things that are very very very dead, as well as the very very very very tiny bits of living things that carry the things our bodies need to know to make stuff.    References: Chipman, Ariel D., and Gregory D.
