Outline the specific differences in the pelvis and the femur that are associated with bipedalism in the human skeleton.
Step by step
Solved in 2 steps
- a) Name one feature present in the foot that are associated with bipedality. b) Name one feature present in the foot that is inconsistent with bipedality.Explain how the structure of the skeleton is adapted to suit these functions: - Haematopoiesis Protection Movement SupportDetermining age at death for sub-adults is achieved by looking at the degree of epiphyseal fusion in several bones from the same individual. Forensic Anthropologists create a chart to illustrate the overlap between the ages at which various fusions occur: Example: the proximal end of the humerus fuses between the ages of 14-23 years old. The distal end of the humerus fuses between the ages of 11-18 years old. If the recovered human remains humerus has an proximal end that is almost but not quite fused and a distal end that is fused solid, then we can estimate the age at death as between 14-18 years old.
