     Are we getting more intelligent? The fact is that IQ scores have increased sharply in many countries of the world, Britain, the USA, Argentina, China and Canada to name only a few. The average child today is as bright as the near genius of 50 years ago."This destroys our belief about the rigidity of IQ, "says Prof Neisser of Cornell University. Even if we do not consider the problem of whether IQ is a satisfactory description of intelligence, we still have to find an explanation for this increase. Neither nature nor environment alone answers the question. Some research indicates that genetics accounts for 75% of the difference between one individual and another. So there's not much room for environment. But in a group of people genes do not change fast enough to explain the rise in scores over the last 50 years. And in any case most psychologists continue to believe that genes explain the differences in IQ. A recent study by Dickens and Flynn suggests that genes do indeed have an important effect, because they encourage people to look for certain environments and certain life experiences. Biologically bright children tend to enjoy school, books, puzzles, asking questions and thinking abstractly. All these things tend to increase brainpower. You will probably study more, choose bright children of the same age as friends, thus boosting your intelligence even more. A child who loves stories will ask his parents to read to him night after night. This will improve his cognitive skills and he will perform better at school. On the other hand a child biologically less gifted may get frustrated at school and come to hate learning, thus reinforcing his genetic tendencies.

     There are two groups of people who live in the rain forests of Africa—Bantu villagers and Pygmy hunters. The two groups have very different ways of life. But they have learned to survive in the rain forest by depending on each other. 
     The Pygmies live as hunters in the rain forest. They live in large groups of families and hunt with nets. The men go to an area where they know there are animals. They hold up nets and the women and children spread out and drive the animals into the nets. 
     Hunting is a full-time job for the Pygmies, so they cannot always stay in villages. But over the years, the Pygmies have learned to enjoy some of the luxuries (奢侈品）of village life. Their forest foods of meat, fruit and nuts are enough for them. But they also enjoy some village foods—like rice, beans, peanuts and vegetables. They also need some metal tools that are made by the villagers.
     The villagers are Bantus. They stay in the clearings（空地）in the rain forests. The Bantus cannot keep cattle in the rain forest. There is not enough room for the cattle to feed. So the Bantus are given meat by the Pygmies. To the Bantus the rain forest is a dangerous place. But to the Pygmies it is familiar. So the Pygmies fetch firewood and guard the village fields from wild animals.
     The Bantus must work very hard to clear their fields. Once they are cleared, the villagers must fight continually to keep the rain forest from taking over again. The soil of the rain forest is so poor that the farm crops soon wear it out. Then the villagers must give the land back to the forest after a few years' farming and clear more.
