It’s still International Women’s Day in some parts of the world. There are still people who believe their feelings about their gender can trump biological facts. There are still people who risk their jobs if they question gender ideology. But there are also people fighting back, among them is Sall Grover: The founder of a […]

I’ve written sentences like this many times: “While biological sex is a binary, gender in humans forms more of a spectrum.” But I was never really sure what “gender” meant. I know that it’s generally synonymous with “sex”, but that is clearly not what I meant when I spoke as I did above. What did […]

I guess the number of papers and articles people send me about the definition of sex is one sign that it remains an important issue for the populace. Indeed, I think that in future decades people will see the kerfuffle about a simple and widely accepted definition (the gametic one) as a tempest in a […]

I have two announcements this morning: a.) First, next Monday, Mar 3 at 12:30 Chicago time (1:30 Eastern time), I am having a 1-1½-hour discussion with DIAGdemocrats (“DIAG” stands for Democrats with an Informed Approach to Gender. And their slogan is “Liberals guiding our party back to reason and reality.” It’s tailor made for me!) […]

Jon Klick finds that when courts in CA surprisingly invalidated a set of DEI laws, the market value of firms subject to those laws increased: California mandated that firms headquartered in the state include women (SB 826) and underrepresented minorities (AB 979) on their corporate boards. These laws, passed in 2018 and 2020 respectively, were […]

This article was mentioned in a comment by reader Ted Gold, but I thought I would highlight it just to show that when the rubber meets the road, people recognize that, yes, there are just two sexes. This is from the NYT on Feb. 25th. Click headline to read, or find the article archived here. […]

While thinking about about objections to the sex binary—usually discussed in humans but sometimes in other species—they all seem to come down to a single assertion: “Sex is complicated in both development and expression, involving chromosomes, behavior, hormones, genitals and even psychology. Therefore there are more than two sexes.” One example of this is from […]

And so we come to the last sex post of the day—about a new piece by Richard Dawkins on his Substack site, The Poetry of Reality. Richard points to what he sees as arrant hypocrisy in the statement on biological sex by the Presidents of the SSN, ASN, and SSB. As I mentioned in my […]

There will be a few posts on the definition of sex today, as everything “dropped”—as the kids say—at the same time. First, on January 20, the Trump administration issued an executive order, “Defending women from gender ideology extremism and restoring biological truth to the federal government”—an attempt to efface gender ideology from the government and […]

Six days ago I posted a group letter to the Presidents of three ecology/evolution/systematics societies who had issued a joint statement that many of us found deeply misguided. As I wrote at the time: The Presidents of three organismal-biology societies, the Society for the Study of Evolution (SSE), the American Society of Naturalists (ASN) and […]

The pdf with the numbered references is here. The paper is about how the evolution of two different types of gametes […]

As I reported recently, the Presidents of three organismal-biology societies, the Society for the Study of Evolution (SSE), the American Society of Naturalists (ASN) and the Society of Systematic Biologists (SSB) sent a declaration addressed to President Trump and all the members of Congress. Implicitly claiming that its sentiments were endorsed by the 3500 members […]
