  • In support of the Trivers & Willard model of adaptive variation in birth sex ratio, recent research showed that high-ranking female domestic pigs, Sus scrofa, gave birth to a greater proportion of sons than low-ranking females. Differences in maternal nutritional status caused by differential access to food of high- and low-ranking females, or differences in adrenal activity as the result of stress experienced during agonistic encounters are two possible mechanisms underlying these findings… CONTINUE READING
