    I wonder if the data set allowed a comparison of chore overlap. As in, perhaps it was less about gender roles and more about disagreements over shared chores.

    I can find Science… Sort of and The Titanium Physicist on the xbox store for my Windows 8 phone. But you are not there and that isn’t good. Can you fix?

    As to the potential knowledge loss should pubic lice go extinct: I can’t recall now where but I read an article that said that the divergence of head lice from pubic lice helped establish when we started wearing clothes. Our hairless midsections developed and segregated the species for long enough to get divergent evolution.
