Exploring How Identical Twins Can Have Different Sexual Orientations



This video (highlighted by Sully) is a fascinating piece by National Geographic that explores the possible explanations for why one identical twin can turn out straight while the other turns out gay:



One thing that irks me about the start of the piece is how it refers to the "controversial question" of "Are people born gay?".

I suppose that it's accurate to describe it as a "controversial" question, but only in the category of controversial questions like "Did humans evolve from monkeys" or "Is the Earth more than 6,000 years old?".

The only reason the "controversy" exists is because nuts peddle religion-inspired nonsense that seeks to refute all scientific evidence to the contrary.

The only true "controversy" in scientific circles on this question is what specific combination of biological factors (e.g., genetics, hormonal levels in the womb, epigenetics, etc.) come together to produce The Gay.

There is no serious debate as to whether being gay is a product of a volitional choice after birth.

Anyway, that's it for my rant. Very good video otherwise :).
