Locomotion

We are trying to understand the locomotion of one of our closest living relatives , which is the orangutan, and also the locomotion of all of the apes and the common ancestor of humans and the other apes. And in that area, we have had a big problem traditionally , and we know a lot about how they move around the forest. We've been out in the forest and spent a year recording the different types of locomotion they use, but we have no idea about the energetic cost of how they move around the forest and the solutions that they find to problems of moving around the canopy. What we're doing here is using the park and the athletes as an analogy for a large-bodied ape moving around a complex environment and getting them to move around in a course that we've made that they've never seen before. And we're going to record their energetic expenditure while they're doing it.
