THE SAME, BUT DIFFERENT

Identical twins have the same physical appearance. Look at this photo of identical twins—they both have short, straight dark hair, and dark color eyes. They are the same height, and they both wear braces. On first impression, identical twins look the same, but there are some differences in their looks. Patrick Flynn, a computer scientist from the University of Notre Dame, in the United States, uses computer technology to look closely at identical twins. This technology can see small differences, such as freckles or the shape of the eyes. The personalities of identical twins can also be different. One twin may be shy, while the other twin may like to talk a lot. Researchers believe that things such as education and the environment can cause these differences as identical twins grow up.
