家园 黑猩猩是小个那个

个头比人大的那个是大猩猩 Gorilla,这个家伙的作案工具确小。

不过按比例说,黑猩猩Chimpanzee跟人也差不到哪里去。

. The human penis is unusual in many

different respects. It is abnormally large, compared to other primate species. The average length of a human penis is five to seven inches(1). The closest genetic relatives to humans are chimpanzees. The average chimpanzee penis is about half of the size of human penises, or about three inches(1). The gorilla’s penis is the smallest, at only an inch long.
