Which mystery fossils are Neanderthal?

The images below show the skulls of a male and female primate from the same species. Based on the physical characteristics, determine which skull (A or B) is male or female, and the probable social system these primates (2 points). Describe the testicle to body size ratio for males in this social system and briefly explain why you would expect this ratio (2 points).   

You are in the field in South Africa and discover the remains of a fossil primate. Upon measuring the long bones of this primate, you find the results shown in the chart below. Use the appropriate equation to calculate the intermembral index and determine the pattern of locomotion used by the primate. Provide your numerical answer and the pattern of locomotion in your answer. Show your work!
