Alan Sanders, an associate professor of psychiatry at Northwestern, will be looking at the whole genome of about 1, gay brothers using the genetic marker technique that Hamer used. A sample that big should eliminate the statistical weaknesses that plagued Hamer.
When two brothers come from the same mother and father, about 50 percent of their genes should be identical. He has already started mapping the first and estimates that by mid the world will know where—if anywhere—to find the gay gene. If either Bocklandt or Sanders is lucky enough to spot the genes responsible for homosexuality, there will most likely be more questions raised than answered.
Even if social pressures through the ages led some gay men to have some children, the significantly lower rate of reproduction would eventually lead to the disappearance of the gene as Hamer does note in his book, The Science of Desire: Possible explanations abound, but an ingenious one was recently put to the test.
Perhaps, the theory goes, some genes, when found in men, make them more likely to be gay and when found in women make them more likely to have children. The increased number of grandchildren that a parent might have through such a superfertile daughter would offset whatever loss of genetic posterity comes from having a gay son.
Whatever the mechanism, it turns out that an Italian study found that women with gay family members have more children than women with all straight relatives. Andrea Camperio-Ciani, a professor of ethology and evolutionary psychology at the University of Padua, interviewed 98 gay men and straight men and found that the mothers of gay men had an average of 2.
That study has been criticized in some circles for the same old reason: The sample size was not big enough. But the man with the generous sample size hopes to answer that question too. How many do they have compared to the relatives of straight men?
Wilson first put forward this idea of kin selection as an explanation for homosexuality inbut for some time now it has been considered an unlikely scenario. Michael Bailey conducted a study in to find out if gay uncles treat their nephews and nieces any better than straight uncles treat theirs.
Thinking that Bailey did not control for the income level of the uncles surveyed—richer uncles tend to be more generous—Qazi Rahman, a professor of psychobiology at the University of East London, tried to replicate the study in England.
But 21st-century Western society, and the homosexuals therein, could be something of an anomaly in human history, according to Paul Vasey, an associate professor of psychology at the University of Lethbridge in Alberta.
Another problem with kinship selection studies that look only in England and, in particular, the United States, is that kinship ties for homosexuals might not be as strong as they would be elsewhere.
These men, who grow up to dress and act like women and are extremely integrated into their society, would be offended to find themselves described as homosexual. To make sure that these traits do not merely reflect a more general fondness for all children, Vasey will soon head back to Samoa to refine and, with luck, replicate the study.
The more intolerant the society, the more likely it is to maintain gay genes. This is especially true if gay genes are also responsible for making women more fecund. Imagine, for instance, that for every extra child that such a gay gene—carrying woman has, a gay man can have one fewer and the balance necessary for the survival of the gene is still maintained.
The more children he has, thanks to what his contemporaries demand of him, the less evolutionary pressure there is for his female counterpart to have more.For Aravosis, and many gay activists like him, the public will only accept and affirm gay people if they think they were born gay.
And yet the available research does not support this view. Contrary to the typical argument that homosexuals are "born gay" as "who they are" and cannot change, the APA officially recognized sexual orientation change in Born Gay: Truth and Circumstances.
