Abstract
In Homo
sapiens and other species, promiscuity,
risk-taking, and aggression are less matters of sex (having XX vs. XY)
than gender (giving PI vs. resources and/or genes). Classic role
reversals include: sea-horses, polyandrous birds, and a few heiresses
in England and Rome. Unlike other females, but like many males, they
are assertive, they take chances, and they are not chaste.
