“Springer and Lewis both have peculiar elements to their headaches,” said Dr. It has long been thought to be without genetic basis, but scientists now postulate that heredity may indeed be a factor in this viselike pain caused by muscle contractions, the most common type of headache. Jim and Jim were undoubtedly the catalysts.”Īmong the medically significant findings in the study of Springer and Lewis is a form of headache called “mixed headache syndrome,” a tension headache that turns into a migraine. “The University of Minnesota will literally be the world center for the study of twins reared apart. “It could be the most dense volume of data ever gathered on any group of people,” said Bouchard. Nearly 20 other such pairs have come to the attention of the Uniirersity of Minnesota researchers, and at least eight of them have already been enrolled in the study (others are being courted assiduously for their participation). The publicity surrounding the meeting between the Ohio twins may well have set the stage for the most extensive study ever to be performed in the United States on “MZa's,” the scientific notation which describes longseparated identical twins (monozygotic, or single‐egg, twins reared apart.) In fact, I'm flabbergasted by some of the similarities.”Įven more interesting to researchers about twins like Springer and Lewis, however, is the fact that they are a “living laboratory” in which it is possible to examine closely the relative influence of heredity versus environment on the medical and behavorial aspects of human development. But when you start to compound the coincidences, they become highly unlikely very quickly. “The probability of two people independently being given the same name is not that rare.
Bouchard Jr., director of the Minnesota Study of Twins Reared Apart Project, a team that gathered to look into Springer, Lewis and other twins separated in childhood. “If someone else brought this material to me and said: ‘This is what I've got,’ I'd say I didn't believe it,” said psychologist Thomas J. “A lot of times, I'll start to say something, and he'll finish it!” (Researchers said when asked about this phenomenon that identical twins are known to have remarkably similar brain waves, which may contribute to the perception that such twins “think alike.”) Doctors and scientists were equally surprised by the findings. “We even use the same slang,” Lewis added. “This is really blowing our minds,” said Springer. ■ Their smoking and drinking patterns were nearly identical.
