Jerry A. Coyne and Luana S. Maroja, academic biologists, have presented an excellent overview piece about the war in biology, a part of the cultural wars. This refers to the march of Left wing thought through the institutions, and now penetrating into the sciences themselves. They discuss the issue of race, which I know the most about in their topics, but I think there is much more to be said, but we have covered this in other blog pieces. Of greater interest to the hot topics of today is the gender agenda, particularly the biological propositions that the trans lobby have promoted, such that the human sexes are non-binary, and exist on a spectrum. They refute this argument by pointing out that the vast majority of people have either male or female bodies, defined via genetics, male XY, female XX chromosomes. Then there are primary sexual characteristics, such as genitalia, and secondary sexual characteristics, such as bodily features such as breasts in females.
The counter made by the trans proponents is that intersexual exist, people who have male and female parts. That is true, but that does not show that the sexes do not exist, but instead presupposes the very categories of male and female that are supposedly rejected, so their argument is inconsistent. There are organisms which are neither plants nor animals, such as fungi, but that does not show that the plant/animal distinction does not exist.
