And how does growing a human make someone more qualified to shuttle kids back and forth to after school activities?

I know your question is not serious, but there are actually a large number of genetic behavioral differences between men and women that make them more easily accustomed to child care.

It's no surprise that the childcare/teaching industries are almost entirely made up of women.

My question was genuine, if absurd. And I would ask the same of you: Which “genetic behavioral differences,” specifically, make someone more qualified to shuttle kids back and forth to after school activities?

There’s also some research that over-representation of women as K-12 teachers is responsible for the growing education gap where men are falling behind women. It isn’t just women who are held back by gender stereotypes.

I think your questions assume a lot of things:

- Women do most of the shuttling of kids? I've yet to see any evidence of this.

- There are differences between the genders, but 'genetic behavioral differences' is a very broad and deep assumption regarding nature vs nurture and opens a whole other spectrum of basic questions.

- Over representation of a gender in some particular field. Being equal does not mean we all have the same aptitudes and interests.

I wonder why no one addresses the lack of representation of males in some highly female dominated sectors. For example male nurses are a minor fraction of the number of female nurses.
