Share knowledge Mould the mankind
When facing a complicated containing the intelligence of sticking paper or food and training the case, the infant should be much better than chimpanzee or monkey when getting the behavior of the content thing.
According to a new research, a reason among them is that children can help each other.
In the research, 8 3 reach 4 -year-old children, 8 groups of chimpanzees (Pantroglodytes) ,And a group of capuchin monkeys (Cebusapella) Trained the case for some intelligence, these cases can be opened through 3 different steps, thus get the final reward.
The result reveals, after over 53 hours, a few chimpanzees or capuchin monkeys finished all 3 steps, but half of child has only spent two and a half hours opening all cases.
In addition, researchers also find, after a person that in a group of children has solved a step of the difficult problem, they will often tell other people how to solve this problem, or let other people watch this course and imitate the method to solve problem - -But the cooperative behavior has not been found in the chimpanzee or capuchin monkey, they will often consider earnestly alone when being baffled by the case.
Culture of this kind of accumulation - -Several generations are based on innovation of their ancestors - -Only appear among the mankind. This new research indicates a characteristic of the human behavior contributes to driving this kind of difference.
Researchers point out, these discoveries can help to explain why is as time goes on, mankind's ability in accumulating cultural knowledge is the uniqueness like this. Though other animal too can study each other, human culture can generation upon generation of become more and more complicated only.
Biologist L.G.Dean and colleague in St Andrews University of Britain have reported this research results on Science published on March 2.
