　　答案：　A

　　All social animals communicate with each other，from bees and ants to whales and apes，but only humans have developed a language which is more than a set of prearranged signals.

　　Our speech even differs in a physical way from the communication of other animals.It comes from a cortical (脑皮层的) speech centre which does not respond instinctively (本能地)，but organizes sound and meaning on a rational (理性的) basis.This section of the brain is unique to humans.

　　When and how the special talent for language developed is impossible to say.But it is generally assumed that its evolution must have been a long process.

The beginning of human language will perhaps remain a mystery.By contrast the beginning of individual languages has been the subject of very detailed study over the past two centuries.
