| For years scientists have been arguing about whether nature or nurture (后天) decides what people will be like. Is it nature-what people are 1 with-that decides what they will be like? 2 is it nurture -what 3 to people when they are born -that decides what they will be like? Scientists have been studying twins to 4 if they can find the answer, because twins start out with the 5 DNA. Sometimes twins don't live together at birth and grow up in different 6 and different places- so the nature is the same for both, but the nurture is different. When scientists 7 these twins in their later life, they some times find some surprising 8 . Jim Springer and Jim Lewis were adopted (收养) by two different families at birth. They first met each other again thirty-nine years 9 and discovered they had a lot in 10 . Both had been 11 twice. Their first wives were both named Linda and their second wives were both named Betty! Each twin had a son - one called his son James Alan and the 12 called his son James Alan, too. Their children each had a dog called "Toy". They even arrived at their first 13 in the same color of car. So far twin 14 seem to show that both nature and nurture are important.
