Thank you for engaging with the article in this depth. I might be able to help you clear up some of your concerns and will try to do so best i can.

Mounting evidence from exercise science indicates that women are physiologically better suited than men to endurance efforts such as running marathons.

This has been an ongoing discussion for years now. There have in fact been several scientists who have made the same claim. You are right to be critical here.

This study from 2015, that analysed the performance differences between men and women from 1971 to 2012, in 50 -mile to 3100-mile ultramarathons, comes to the conclusion that men outperform woman, although they point out that one reason for the gender gap might be that less women participate in marathons.

But this preprint (!) from 2023 suggests that, even with equal participation numbers, men still outperform woman.

Either way, it still is an ongoing debate. While the quoted sentence you chose is clearly not backed up by data the authors at least hint towards this by stating that "We still have much to learn about female athletic performance [...].". I still agree: the statement as made is incorrect.

I'd like to point to this article and this study, that seem to point towards men and woman using different pacing strategies in marathons, possible showing how they could have fulfilled different roles during hunting.

The article addresses a relevant point a bit further down: "The inequity between male and female athletes is a result not of inherent biological differences between the sexes but of biases in how they are treated in sports. As an example, some endurance-running events allow the use of professional runners called pacesetters to help competitors perform their best. Men are not permitted to act as pacesetters in many women's events because of the belief that they will make the women “artificially faster,” as though women were not actually doing the running themselves."

Still, i would say the evidence is at least unclear and does not back up the statement made and therefore rightfully criticised by you.

Also I’d like to point out that all of this might be of no relevance at all to the question, if woman hunted alongside men or not, since the idea that humans outran animals as a hunting techniques (e.g. "persistence hunting") has been heavily challenged and, to my limited understanding, debunked. But this is not my field, so i am not familiar with a lot of sources on the topic. I am happy to be corrected here.

I wouldn’t say “superior” like a value judgement that muscle strength is the most important thing in terms of physical ability, but I don’t think that it’s controversial that the average man is physically stronger than the average woman, or that being pregnant interferes with your ability at physical tasks. This article keeps going on about how it’s clear that there’s not any physical difference when it is blatantly clear from sporting events that (in the average, accounting for individual variation) there is.

Have a look at the sources they give in the article. This paper seems to be the main source for the article. In regards to your concerns it states that:

"While there are real, uncontroversial mean biological differences between females and males, the differences that give females an advantage are not only regularly ignored but also understudied. Because of this, science poorly understands female athletic capabilities in terms of strength, endurance, and fatigue. Until this uneven understanding is rectified, our reconstructions of past sexual divisions of labour will be biased and limit the likely broad repertoire of activities females participated in during our evolutionary past."

In regards to your question why movies and gender roles are part of the article, i would like to ask why this seems to be problematic for you? The context for both seem quite clear? "Gender" (not Sex) is, according to Gender-Studies, something "performed". Movies and how we talk about Gender-roles very much form, how people frame a Gender and assign roles to it. The article is stating (and in my opinion correctly so) that it makes a difference if a society "performers", or believes in the idea of male only hunters, as this leads to a bias in the scientific literature and field. Why would this not be included in a scientific article? Its based on quite solid science (other than the whole endurance idea they are promoting). Maybe you could elaborate a bit why you find it not relevant?

You can talk about the biology and anthropology of XX chromosome people and XY chromosome people without getting into this

But that’s not the only topic at hand, isn't it? They clearly state that in scientific literature it is not made clear when they are speaking of biological or social genders. And it makes a difference if you are addressing gender or sex. Further, it is important to differentiate between the concepts of gender and sex, because they want to make clear where they speak about biology and where they speak about the constructed (or "performed") gender of female.

What the fuck is this I feel like I’m taking crazy pills

Why? What is the crazy part to you? Do you disagree with the statement that science has been extreme male focused? As far as i can tell it indeed has been and still is. What’s crazy in pointing that out? Or do you disagree?

This was the first part that made me think, oh shit, maybe I am the wrong one, all this stuff has been valid and I’ve just been being Joe Rogan and poo pooing it all. Nope, it’s just more made up stuff. If Hitoshi Watanabe is sexist (which apparently he is), then this is off the fuckin charts.

I don’t get why it’s a bad thing when male scientists bring their biases into their papers to the point of ignoring that data and just inventing their own imagined world to fit how they like to see it (which, it is, of course, a very bad thing), but all of a sudden if a feminist does it, it turns into a good thing.

Yes! I absolutely agree. None of their three chosen examples showes any female dominating in any category, neither once or "regularly". It is bad practice to make such a claim. I wouldn’t label it as sexist. It's just really bad science. And it invalidates a lot of the very sensible and very much proven point the authors make. And I agree with you: It is not a good thing when anybody does this, regardless of agenda.
