Sexual Dimorphism Discussion

I’m stuck on a Science question and need an explanation. Comparative Anatomy: Discuss sexual dimorphism as it applies to humans. Discuss at least three specifictraits observable in the cranium or post-cranial skeleton where males and females differ explain the differences. Nowcompare human sexual dimorphism to the degree of sexual dimorphism found in great apes. How does this correlate with our social organization? How do some or all of the traits you describe reflect evolutionary trends?
