Description
The gang discusses two papers that use morphometric studies to investigate patterns of ecomorphy in the fossil record. Specifically, they look at two papers that investigate how morphology in sloths and pterosaurs changes over time, and how well these changes map onto changes in body size and ecological shifts. Meanwhile, Amanda could be dean, Curt has opinions on figures, and James provides butchery advice. Up-Goer Five (Curt Edition): The friends talk about two papers that look at how things look and how that changes over time, and looks to see if these things are changing because of what they do. The first paper looks at animals with hair and long arms that move very slow. There are not a lot of these animals today, but in the past there was a lot of these animals and they did a lot of other things that we do not see them do today. These animals were also looking different as well. But it seems that the things that look different are closer to each other by being close sisters to each other. They also do find that these animals are also doing different things when they look different. The second paper looks at angry animals who can fly but are not the animals that can fly today. These animals start small and get big over time. They actually get big a few times. This paper looks at the parts of these animals and shows the many different ways that parts can change to make these animals big or small. It also shows that, when these things get really big is when the group seems to be doing really bad. References: Yu, Yilun, Chi Zhang, and Xing Xu. "Complex macroevolution of pterosaurs."
