Do humans have Lambdoidal crest?

Sagittal crests are rare in adult male chimpanzees and female gorillas, and are unknown in female chimpanzees, female orangutans, and humans and bonobos of both sexes (and are also absent in juveniles of all species). The crest provides a surface for the attachment of the large chewing muscle, temporalis.

Do humans have a zygomatic arch?

Zygomatic arch, bridge of bone extending from the temporal bone at the side of the head around to the maxilla (upper jawbone) in front and including the zygomatic (cheek) bone as a major portion. In modern humans the zygomatic arch is more prominent in some populations and is larger and more robust in males.

Why do humans not have sagittal crest?

Modern humans do not have sagittal crests because we do not have to chew tough foods like apes do or our ancestors did. While our jaw muscles end just below the ear, in a species with a sagittal crest they would extend all the way up, giving them the extra power they need to eat.
