It seems that every year or two there is an article somewhere that some scientist or doctor has identified a biological "cause" for being gay or transgender. These kinds of things seem to get a significant amount of attention and then fade into obscurity until the next bombshell discovery is made. In 1993 there was much fanfare over an article published in Science magazine about the discovery of a "gay gene." Did that settle the question of whether or not sexuality is biological or learned? Of course not. That investigation continues today.
