The gang discusses two papers that use new fossils to add insight into the geographic origins of groups. The first paper looks at some fossil freshwater dolphins and the second paper looks at fossil jumping spiders. The gang also uses these two papers to talk about a lot of other things because, despite being short papers, there is a lot of related things to talk about. Meanwhile, James is pretty sure he read the papers, Curt has very uninformed opinions, and Amanda gives everyone a panic attack.

 

Up-Goer Five (Curt Edition):

The friends talk about two papers that use old animals to see where animals may have been in the past. The first paper looks at animals with hair that live in the water and have moved into water that you and I can drink. This is a paper about one group of these animals and some bits of an old animal that were found in a place very far away from where these animals are today. This might mean that these animals moved into water than you and I could drink many times over the years and in many places.

The second paper looks at a small animal with many legs and hair that eats other small things. These animals are hard to find parts of in the past, but this paper finds a really nice one in a place that is important for understanding how they got where they are today. This group is found in areas that were close to each other in the past but have moved further away. This old animal being found where it is gives us more ideas about how these animals got to where they are today.
