Well, I wasn't the one who brought up biology and in fact in my brief mention suggested there were some questions. The larger issue is trans-historicly men tend to be, well, pioneers, and women tend to follow and build civilization. To the extent that there is a biological inherent risk aspect, it is because of differences in timeframes to establish a family. Men and women are different in this regard biologically. Men can have kids when relatively old while women cannot. For this reason if you expect someone to take risks while young, this favors men over women, particularly if the risk is that one might not be as established by the time one is, say, 30 years old. It is different, for example, to require an extensive post-doc program followed by a lengthy tenure track in order to get a coveted academic position if you are a man and can delay getting married and having kids than if you are a woman.
