In another dimension to sex structure biology antagonism and sexual selection, unlike the female ZW sex pairing of birds male ZZ where female selection favours male genes and hence showy sons, the XY male XX female mammals have female selection skewed to favour alleles advantageous in daughters, R4 a discovery which may explain why women appear to sex structure biology a step ahead of men in evolution, being more neotonous child-likeless hairy, and explain pronounced female sexual characteristics in breasts, buttocks, concealed estrus and ecstatic clitoris. Anne Fausto-Sterling for example Campbell R 16 claimed that an association old man wants sex low parental investment and promiscuity was just an argument for the male status quo, citing birds called sea snipes or phalaropes, in which it is the females which are promiscuous:
