L. Newson et S. Lea, The limits imposed by culture: Are symmetry preferences evidence of a recent reproductive strategy or a common primate inheritance?, BEHAV BRAIN, 23(4), 2000, pp. 618
Women's preference for symmetrical men need not have evolved as part of a g
ood gene sexual selection (GGSS) reproductive strategy employed during rece
nt human evolutionary history. It may be a remnant of the reproductive stra
tegy of a perhaps promiscuous species which existed prior to the divergence
of the human line from that of the bonobo and chimp.
