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).
