关于骨頭

刚刚讨论,男人是否比女人多一支骨?Google 一下,找到几种答案。。。

圣经上说:
上帝说 这样吧
很简单
我从你的体内拿一支骨出来
用你的这支骨造一个女的
这样应该能够使你们 在一起才对

科学上的答案模糊不清,没找到正确的答案。

...There are many differences between the male and female human skeletons. Most prominent is the difference in hip bones, owing to differences related to the process of reproduction, and very likely also to the biological process of sexual selection. Men tend to have slightly thicker and longer limbs and digit bones, while women tend to have narrower rib cages, smaller teeth, less angular mandibles, less pronounced cranial features such as the brow ridges and occipital protuberance (the small bump at the back of the skull), and the carrying angle of the forearm is more pronounced in females.

这个没讲多少支... 下一个有...

...How many bones do humans have?
When you were born you had over 300 bones. As you grew, some of these bones began to fuse together. The result? An adult has only 206 bones!

对吗?你懂吗?
