I won’t pretend to know anything intricate about biology.I find it remarkable people still haven't realized nature is messy and sloppy, and black and white only exists to what can see them. And for all we know, it still laughs at us when we realize we know less than we did we tried to figure it out. It laughed at so hard that it dwarves anything we used to think as the totality of Creation. We're wrong and wrong again and wrong some more.
And it every way possible, it doesn't give a damn what we think about it.
But there seems to be a disconnect between the acknowledgement of the nuances existing in the human species and humans being either male or female
Which may be due to the religious aspect in society, I sincerely don’t know. Not American. Just an observation.
Either way, I’m forcibly reminded of literally the first thing I had to copy from my high school biology text book
And I quote
“It is scientifically impossible for a population of humans to be comprised of males which are all 100% male and females which are all 100% female.”
Basically acknowledging that intersex conditions exist, among other “anomalies.”
