Document Summary
Finding the way: locomotion is a way to find and attract mates, locomotion helps find food. Why consider locomotion: general theme of limitations of different physical environments. For example terrestrial environments there were overheating in larger animals. The increase in volume was a higher increase than surface area. Here you are thinking of the cross-sectional area that supports the animal. For example if you are thinking of the cruds that supports the bones. The limit is that there needs to be a large mass to support the increase of cross sectional area. Increase in mass supported by increase in cross sectional area: the choice of locomotory adaptations there are costs involved. How are muscles and bones working together to reduce cross: why is running more costly for animal (figure) an animal of the same size, running is more costly. We are looking at overall evolutionary trends. Make sure you can interpret this each other. graph.
