Abstract

In developmental terms, the human hand is at the same time both specialised and primitive. Its manipulative ability, though somewhat better than that of the apes and monkeys, has lost strength compared with hands of recently extinct species of Man, and shows some evolutionary characteristics seen in reptiles of 250 million years ago. Its evolution, as presently understood, is described.

摘要

从发育角度来看，人类的手同时具有特化和原始的特点。其操作能力虽然比猿类和猴类略强，但与近代已灭绝人种的手相比，力量有所减弱，还展现出一些两亿五千万年前爬行动物所具有的进化特征。文中描述了目前所理解的其进化过程。
