Differences between men and women

I've often argued along these exact lines:

While Darwinian thought has no impact on the priority we give to equality as a moral or political ideal, it gives us grounds for believing that since men and women play different roles in reproduction, they may also differ in their inclinations or temperaments, in ways that best promote the reproductive prospects of each sex. Since women are limited in the number of children they can have, they are likely to be selective in their choice of mate. Men, on the other hand, are limited in the number of children they can have only by the number of women they can have sex with. If achieving high status increases access to women, then we can expect men to have a stronger drive for status than women. This means that we cannot use the fact that there is a disproportionately large number of men in high status positions in business and politics as a reason for concluding that there has been discrimination against women. For example, the fact that there are fewer women chief executives of major corporations than men may be due to men being more willing to subordinate their personal lives and other interests to their career goals, and biological differences between men and women may be a factor in that greater readiness to sacrifice everything for the sake of getting to the top.
