The linked article explicitly does not take any stance on that. What the article points out is that males are more extreme in their traits, eg. exceptionally tall or exceptionally short, which in no way means that there are average differences. Even if the deviation is different, the mean may be the same.
Not that I'm saying that those differences are or are not there, but to say that the current differences are entirely due to biological differences would seem a bit naive to me.
You managed to misquote BADLY the article to support your point.
The article opens stating that there are TWO types of gender differences, one, like Height (that you quoted wrongly) is when the mean changes.
The other (like IQ) the distribution changes.
Then the article focus on theorizing why that second type happens, and don't discuss the first (wisely for the author, the same website used to have other authors on the subject, and they were all fired after public outcry after focusing on the first type of differences).
Indeed, I wasn't really trying to quote the article when I was talking about height, I just took a bad analogy on my own (certainly influenced by what I just read, but that's not the point). Sorry for the confusion.
hence, if you sample either tail of the distribution you get on the average more men than women. and sampling one of the tails is exactly what selective schools/companies/sports clubs/etc tend to do.
More extremes in males is true, but height was exactly one problem where the mean really deviates and the curve is pretty much the same. IQ was one where males have way more extremes than women.
