Ph.D Fernando, Harvard Professor of Genetic Epidemiology, knows a thing or two about Twins. He must know as he is head of the Twin Research Department where he works with about 3,500 pairs of identical twins, researching the influence of a person's genes on everything from the probability of being obese, whether or not they have religious beliefs, and, how, do they fall into sentimental issues. Anyone who is a twin, or who has ever met a pair of identical twins, can attest to how remarkably similar they are to each other, even in the rare cases of adopted twins raised in separate homes.A recent article begins with an introduction to two middle-aged twin sisters called Susan and Polly, one of the pairs of twins in the study group of the Department of Research of Harvard. Although they were treated almost as a single person growing up, with cuts from identical hair and clothes, the twins began to diverge in their teens as they they gained the freedom to make their own…
