Title: Is there a biological base to sexual orientation?
Post by: iacopo.russo on 06/10/2021 14:24:59

A listener wrote to us to ask:

Hi! There are people who identify as e.g. bisexual, homosexual etc. Is it possible that it is also biologically linked?

What do you think?

In humans: not as far as anyone knows. Among birds: some possibility of a genetic predisposition to anomalous sexual preference (expressed as triple parenting) in some species.
