Sex has never been binary

(Verse 1) In the realm of Nature, a revelation unfurls, Biologists now think, we're not just boys and girls. Chromosomal, hormonal, identities diverse, We exist on spectrums, the binary's been burst. (Chorus) We've never been binary, oh can't you see, Nature and sex redefined, in harmony. Five sexes, nine sexes, models galore, The binary's been shattered, forever more. (Verse 2) Fausto-Sterling, a pioneer so bright, Five ways of measuring sex, brought to light. Moore listed nine identities, in '68, No 'male or female' answer, can this debate satiate. (Chorus) We've never been binary, oh can't you see, Nature and sex redefined, in harmony. Tests and averages, norms statistical, Our identities are complex, not just physical. (Bridge) In the arena of sport, the struggle is real, Binary forms insisted, but science appeals. Transgender athletes, in the spotlight, Fluid identities, taking flight. (Verse 3) Barr body test, a proxy for sex, But even its creators, found it complex. "True sex" indicators, they could not be, The binary illusion, we must set free. (Chorus) We've never been binary, oh can't you see, Nature and sex redefined, in harmony. Height, physiology, advantages abound, Yet only sex is tested, fairness not found. (Outro) So remember this fact, when definitions are sought, Scientists never agreed, on the binary thought. Men, women, neither, both, identities true, We've never been binary, me and you. _____ Source: "Nature and sex redefined – we have never been binary" by Dr. Vanessa Heggie The Guardian Thu 19 Feb 2015 08.07 GMT https://www.theguardian.com/science/the-h-word/2015/feb/19/nature-sex-redefined-we-have-never-been-binary
