What is causing Dr. Nelson to make such an earth-shattering statement? His team has found male DNA inside female brains.
These findings are significant for a number of reasons. For one, the researchers found that female Alzheimer's patients have lower concentrations of "male" DNA in the portions of the brain most affected by the disease. This, of course, could have significant implications for those researching Alzheimers, and possibly other conditions.
Also, if a person can have "immigrant" DNA intermingled in his or her cells, the notion that DNA can uniquely identify an individual human being is challenged, to say the least. That undermines one of the most basic notions of genetic science, not to mention the notion that gender is identifiable and definable by DNA structure. Some might argue that such a notion might have gone by the wayside in any event, as DNA structure often has very little to do with the way terms such as "male" or "female" actually function in the world, let alone with how people actually live as men, women, boys, girls or in other gender identities.
Perhaps Dr. Nelson summed up the implications of his findings best when he said, "I think we're better off defining it [the biological self] as an ecosystem, rather than as a singular genetic template, with more genetic and cellular diversity than we previously thought."
Could this spell the end of the gender binary after all?
