For this discussion I would like you to find at least 3 physical features that indicate wether or not an animal is a Biped (please do not say two legs!) . Please explain in detail for each of the three you choose. You will not be able to look at others post until after you have finished yours. Please comment on your fellow students about the features you did not choose.
The point of this is to look at the physical difference of a Hominin vs a quadruped. There is a beautiful picture in the book the shows these traits.
