Document Summary
Modes of selection (more than just directional) Types of fitness (how does he describe inclusive fitness?) Hox genes (how do they fit into criteria for good adaptationist story?) What the fossil looks like and whether it has characteristics associated with a specific species. How do we construct a story about this fossil, we need to rely on analogies. New features we absolutely have to have ; terrestrial bipedalism and reduced canine size. Bipedalism has its pros and cons (cons= lower back pain, support of the organs is lowered as they are no longer contained in the rib cage fully, distal appendages have shifted and the longitudinal arch has shifted) We became bipeds due to our inherent aggressive behaviour, to be bipedal meant you would have your arms free to hold weapons, to hunt and to display dominance (killer ape hypothesis)
