There’s no question of our biological sex

There’s no question of our biological sex, by Colin Wright and Emma Hilton. Colin Wright is an evolutionary biologist at Penn State University; Emma Hilton is a developmental biologist at the University of Manchester.

“The idea of two sexes is simplistic,” an article in the scientific journal Nature declared in 2015. “Biologists now think there is a wider spectrum than that.”

A 2018 Scientific American piece asserted that “biologists now think there is a larger spectrum than just binary female and male”.

And an October 2018 The New York Times headline promised to explain “Why Sex Is Not Binary”.

The argument is that because some people are intersex — they have developmental conditions resulting in ambiguous sex characteristics — the categories male and female exist on a spectrum, and are therefore no more than social constructs. If male and female are merely arbitrary groupings, it follows that everyone, regardless of genetics or anatomy should be free to choose to identify as male or female, or to reject sex entirely in favour of a new bespoke “gender identity”.

To characterise this line of reasoning as having no basis in real­ity would be an egregious understatement. It is false at every conceivable scale of resolution.

Sex is digital, not analogue:

In humans, as in most animals or plants, an organism’s biological sex corresponds to one of two distinct types of reproductive anatomy that develop for the production of small or large sex cells — sperm and eggs, respectively — and associated biological functions in sexual reproduction. In humans, reproductive anatomy is unambiguously male or female at birth more than 99.98 per cent of the time.

The evolutionary function of these two anatomies is to aid in reproduction via the fusion of sperm and ova. No third type of sex cell exists in humans, and therefore there is no sex spectrum or additional sexes beyond male and female. Sex is binary.

There is a difference, however, between the statements that there are only two sexes (true) and that everyone can be neatly categorised as male or female (false). The existence of only two sexes does not mean sex is never ambiguous. But intersex individuals are extremely rare, and they are neither a third sex nor proof that sex is a spectrum or a social construct. …

The time for politeness on this issue has passed. Biologists and medical professionals need to stand up for the empirical reality of biological sex. When authoritative scientific institutions ignore or deny empirical fact in the name of social accommodation, it is an egregious betrayal to the scientific community they represent. It undermines public trust in science, and it is dangerously harmful to those most vulnerable.

Yet another case of reality versus politically correct fantasy. This fantasy seems to be most harmful to kids in puberty, some of whom make irreversible changes that render them unable to have children — all on a PC fad. The big winners are the sexual revolutionaries, who seem to be grooming kids on an industrial scale.
