- An adult Volvox consists of around 2,000 body cells, whose job is to move the organism around using their flagella, and 16 cells capable of reproducing. 一株成年团藻由大约2000个体细胞组成,它们用它们的鞭毛移动整个团藻,而16个细胞具有繁殖功能。
- It was also around this time that mankind's direct ancestor, Homo erectus, the species considered to be the first true human being, appeared in Africa and Asia after replacing more primitive ape-like creatures such as Australopithecus africanus. 也正是在那个时候,人类的直接祖先直立人--据认为是最早的真正的人类--在非洲和亚洲出现,取代了非洲南猿等类猿生物。
