Scientific American dedicates its September issue to The New Science of Sex and Gender, and sociobiologists haven't been in this kind of tizzy since the Emmy-nominated Bill Nye episode about sex and gender.
Above: the usual suspects getting upset.
From the intro to the issue by the editors:
To varying extents, many of us are biological hybrids on a male-female continuum. Researchers have found XY cells in a 94-year-old woman, and surgeons discovered a womb in a 70-year-old man, a father of four. New evidence suggests that the brain consists of a "mosaic" of cell types, some more yin, others further along the yang scale.
These findings have far-reaching implications beyond just updating the biology textbooks. They have particular bearing on issues of personal identity, health and the economic well-being of women. That is because arguments about innate biological differences between the sexes have persisted long past the time they should have been put to rest.
