Podcast 140 - Staying on Ecomorphic Brand


The gang returns to a favorite topic, the link between morphology and ecology. Specifically, they look at two studies that use the morphology of ammonites and early fish as a proxy for ecological complexity. Also, James enjoy controlling giant robots, Curt considers the impact of branding, and Amanda tries a new 14% beer with all of the expected consequences. So enjoy as we get completely sidetracked talking about feet, eating zoras, how Amanda is secretly Tien from Dragon Ball, Warhammer 40k, and Deadpool. So, it’s one of those podcasts. <EDITOR’S NOTE: Actual science talk starts at roughly 16 minutes in>


Up-Goer Five (Curt Edition):

Our friends talk about two papers that look at the way things look and how that changes what you can do to live. The first paper looks at things with long arms and hard covers that move through the water. The paper talks about how old things with long arms are the same and different to things with long arms that live today. It also looks at how these things with long arms change how they look and what they do as they get older. The paper shows that the old things often changed how they looked and do very different things as they got older. Also, the older things with long arms are doing things that are very different from the new things with long arms.

The next paper talks about other things that move through water and are good to eat. It looks at the mouths of these things that are good to eat to see if the mouths have become more different over time. Some people think that the mouths might have become different very early on, while other people think the mouths slowly got more different over time. This paper says that the mouths in the past were probably not as different as the mouths today, since a new group of things that are good to eat has appeared that have very very different mouths.
