Experts can tell if an ancient Egyptian mummy or aprehistoric human was a boy or a girl just bylooking at the skeleton.

The human skeleton offers insight into a person's life:
人类骨骼展现了人一生的生活轨迹:
it will show the signs of disease, malnutrition, and injuries, as well as aging and sex.

Experts can identify a skeleton's sex by looking at two key areas: the skull and the pelvis.

而在脸部区域,有更大的眉弓,更厚的下颌和颧骨,
and the chin is more square than afemale's chin, which is generally more pointed.
下巴则比女性的更厚,通常更为尖锐。
On the other hand, well, not hand, there's the pelvis.
另一方面,不是手,而是通过骨盆。
The female pelvis is shaped like a wide, oval bowl with a large opening at the top and aslightly smaller opening at the bottom.
女性骨盆形状像一个宽的,椭圆形碗，开口顶部大，底部小。
If a female has had children, the pelvis will also show this.
如果一位女性已经生育过,骨盆也将展现出这一点。
