【正文】 thanded. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 . to the 1950s. Most of the people shown in these works are righthanded, so the scientists guessed that righthandedness has always been mon through history. Today, only about 10% to 15% of the world?s population is lefthanded. Why are there more righthanded people than lefthanded ones? Scientists now know that a person?s two hands each have their own jobs. For most people, the hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person?s hands and eyes 第 5 頁 共 53 頁 work together, controls the left hand. The leftside of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be lefthanded, and studies have found that lefthandedness is twice as mon among artists as among people in other jobs. No one really knows what makes a person bee righthanded instead of lefthanded. Scientists have found that almost 40% of the people bee lefthanded because their main brain is damaged when they are born. However, this doesn?t happen to everyone, so scientists guess there must be another reason why people bee lefthanded. One idea is that people usually get righthanded from their parents. If a person does not receive the gene(基因 ) for righthandedness, he / she may bee either righthanded or lefthanded according to the chance and the people they work or live with. Though righthandedness is more mon than lefthandedness, people no longer think lefthanded people are strange or unusual. A long time ago, lefthanded children were made to use their right hands like other children, but today they don?t have to. 1.
