Go to Virtual Skeleton pay special attention to the differences you see in the skull and bones based on race and gender. You must use Safari for your browser for this. Write a blog describing some of the differences you see

Caucasoid skulls have a protecting chin form, high and peaked nasal cross section, a small degree of facial prognathism, a rounded and elongated oval sagittal outline, and a narrow pointed mastoid process. American Black skulls have an elongated sagittal outline, a low and broad nasal cross section, a high degree of facial prognathism, and an oblique mastoid process. Asian skulls have a medial and slightly peaked nasal cross section, a rounded sagittal outline, a broad pointed mastoid process, and a low degree of facial prognathism. Male skulls have a more robust occipital protuberance, pronounced superciliary arches, a larger and more distinct temporal line, and a larger and more downward protuding mastoid process. Male skulls' zygomatic ridge extends beyond the external auditory meatus. Female skulls have parietal bossing, which are often seen in gracile male or female Caucasoids. Female skulls also have a smaller, less downward projecting mastoid process and a vertical and rounded frontal. The zygomatic does not extend past the external auditory meatus, unlike the male skulls.
