人体是个复杂的生物化学系统,表面看上去似乎所有器官都是有用的,而事实上,我们很多人生来身上就带有一些退化器官,很多返租现象或特征都可能重新出现在现代人身上,人体已被证明的多余器官竟总共约有90个之多。
The human body is a complex biochemical system that looks like all the organs on the surface are useful. In fact, many of us are born with some degenerative organs, and many rentback phenomena or features are likely to reappear in modern people. The human body has been found to have about 90 extra organs in total.
