I don't know if all societies have it. Some researches showing that ancient people did not have sex-based labor division and that there is actually less gender in primitive societies pop up from time to time. You can generally notice that the difference in appearance (nonbiological traits) and behaviour between women and men are the biggest where women's reproductive exploitation is the strongest. When women are primarily exploited as work force the same as men, there's very little difference between women and men if any. See how the fashion was changing from early to late middle ages, when the witch hunts were happening, and the purpose of witch hunts was to turn women into a reproductively exploited class. What protective function does gender serve?
