Are some people born gay? It's a question that filmmaker Bryce Sage has always wondered about, especially after he first came out of the closet 11 years ago.
"It doesn't seem to scientifically make sense," Sage, 30, says during a visit to the offices of The Nature of Things in Toronto. "You know, the majority of us didn't grow up in environments where being gay is an easy or a desirable thing."
Sage grew up in Omemee, Ont. -- a small community within Kawartha Lakes and the childhood home of musician Neil Young -- but he came out in Toronto, shortly after he moved there to attend university.
"Instinctively, to me, being gay doesn't feel like a choice. I mean, we don't reproduce, so from an evolutionary perspective, why does homosexuality exist?"
It's a question that has confounded many scientists, but Sage reveals that there may finally be some answers.
His personal journey to discover the science behind his sexuality is the subject of his Nature of Things documentary, "Survival of the Fabulous." In the doc, he meets with leading scientists and even participates in their cutting-edge research.
"I went In expecting to find that there is one single gay gene, a simple explanation for why homosexuality has survived," he says. "I've had to come to terms with the scientific process being much more complicated than that. Any form of human behaviour is not going to be explained by a simple gene. It's much more interplay between genes and the environment."
But the big question is whether Sage found the answer to the big scientific question he posed.
"Is there an answer for why homosexuality exists? Yes, there is, but you'll have to tune into The Nature of Things to find out," he laughs.
