What a "Twinsidence"!
In the 1980s, Thomas Bouchard was curious about nature and nurture. So, he found a bunch of identical twins that had been adopted by different families. These twins had identical "natures" (the same genes), but had different "nurtures" (different life experiences). At the twin reunions, there were some incredible coincidences. Jim Lewis and Jim Springer were separated as infants. When they met at age 39, both were the same height and weight, had dogs named Troy, and had been married twice to women with the same first names. Some scientists see flaws in Bouchard's twin research since there have been studies of twins that have grown up in completely different homes, in different parts of the country, that have nothing in common except for their genes. But one thing everyone agrees on is that both nature and nurture play important roles.
