The gang discusses two papers that use Blender 3d modeling techniques (and other functional morphology techniques) to study arthropod morphology. The first paper looks at trilobite enrollment and the second paper looks at the anomalocaris great frontal appendages. Meanwhile, James likes horses, Amanda has some name ideas, and Curt fails to segue.

 

Up-Goer Five (Amanda Edition):

Today our friends look at two papers that talk about things with legs that have many parts. The first paper looks at very old pretty large things with mouth legs that people can't decide if they were strong or not strong. The paper does lots of computer stuff to figure out just how strong the mouth legs are. They find that the mouth legs are not as strong as people thought they might be and so they did not eat things with very hard parts, probably, but things that were not hard at all. The second paper looks at how cute little things with legs that have many parts might have made themselves into balls. There are many ways that they might have made themselves into balls, with the way the head fits with the back end. They think only one or two were very good, and that it might have changed as the cute little things with legs that have many parts grew up.
