Which we can all agree is both cool and a biological anomaly… much like it can happen in humans.

You should probably read the article first, before jumping into politics: “This particular example of bilateral gynandromorphy – male one side and female the other – shows that, as in several other species, either side of the bird can be male or female. “The phenomenon arises from an error during female cell division to produce an egg, followed by double-fertilization by two sperm,” he explains.

I'm not sure if it could happen in humans, but apparently it has never been observed. This phenomena is called bilateral gynandromorphism and is where the entire body shows both male and female traits (along a bilateral split). You're probably thinking of hermaphrodites (e.g. she-males) which is where the animal only has reproductive organs of both sexes.

  Chimerism exists in humans as well, and likely gynandromorphism as well. I don't think this bilateral version has ever been seen, but more subtle forms may be more common than assumed - it can only really be discovered through genetic testing of different parts of the body.

  It can, and does, I used to know a bilateral chimera, you could clearly tell which side was which by hair colour, she identified as female. Btw, 'she-male' a) does not refer to hermaphrodites, b) is an offensive term, and has been considered offensive for around 30 years, so no 'modern wokism' retort required.

    No offense intended by "she-male" - it's used in the porn industry where it's presumably meant to attract a certain audience rather than be offensive. I didn't realize that these are (always? usually?) trans women.

  The term "shemale" is usually confined to porn, where it refers to transgender women who still have their penis, rather than anything related to hermaphrodites.

I don't think there's any known example of bilateral chimerism in humans? Hermaphroditism is humans (and for that matter, in birds; the above is a really unusual case) works completely differently.

  Perhaps not such a stunning bilateral one, but two-sex chimerism definitely is: https://en.wikipedia.org/wiki/Human_chimera https://en.wikipedia.org/wiki/Human_chimera And I can really only say "perhaps". Humans have often hidden or killed their abnormalities for much of history, and birds significantly outnumber us. (edit: there's a semi-recent example of noticable partial bilateral human chimerism actually: https://www.deccanchronicle.com/lifestyle/health-and-wellbeing/060617/woman-has-two-skin-tones-after-fusing-with-unborn-sister-in-womb.html https://www.deccanchronicle.com/lifestyle/health-and-wellbei... Seems like largely a numbers game to me.)
