WILLIAM M. BRIGGS on that new “gay gene” study: “This appears to be a theory in search of facts; that is, some folks start with the theory that SSA [same-sex attraction] is genetic and work backwards. Women who mate with SSA men, it is suggested, are more fecund: they pump out more babies. What we have is a balancing act. Is it because the women who ‘go for’ SSA men are more fertile, or is it the male gametes from SSA men are causing greater fecundity? And how much more fertile must these women be (by whatever cause) to match the rate of baby making seen in women who mate with non-SSA men?”
