The gang discusses two papers that look at the provide clues to the modern biogeographic distribution of species, specifically bees and new world monkeys. Meanwhile, Amanda shares something, James finds out about where's the beef in more ways than one, and Curt invents a band.

Up-Goer Five (Curt Edition):

The friends talk about two papers that look at where animals live and how those animals got to those places. The first paper looks at group of small animals that fly and go to things that grow their own food and picks up parts of them when looking for food that helps these things that grow their own food make more of themselves. A long time ago, people had an idea that all of these small animals that fly came from one place and them moved to other places. No one had done a big paper using computers to see if this was true. This paper uses computers and finds that it does seem to be true.

The second paper looks at small animals that move in trees and can not fly but are closer to people than lots of other animals. This group came from across a big blue wet thing. However, lots of people wonder how they got across the big blue wet thing. This paper looks at new parts of these animals and sees that maybe these animals got across the big blue wet thing a lot of times. This might mean that at some times in the past it was easier for some of these small animals to make it across that big blue wet thing.
