Man's hand in evolution.
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.
