Scholarcy highlights

  • Married couples in four Solomon Islands tribes did not mate assortatively for body size or shape.
  • All four groups had high correlations between spouses' age and moderate correlations, 0.3 to 0.5, for age-associated traits like nose height, ear length, and grayness of hair.
  • Three brownskinned groups from Malaita showed significant assortative mating for skin color whereas the very dark-skinned Nasioi, from Bougainville, did not.
  • The positive correlations between spouses for skin color, with r's for various bodily regions ranging from 0.2 to 0.6 in the three Malaitan tribes, persisted when age was partialled out.
  • As expected with assortative mating, the Malaitans' skin color was highly variable.
