Final answer:
Intralocus sexual conflict over human height examines how the same genetic factors affect males and females differently in terms of sexual attractiveness, with cultural preferences potentially influencing average height differences between populations.
Step-by-step explanation:
The concept of intralocus sexual conflict over human height refers to the evolutionary biology principle that the same genetic factors can have different effects on the fitness of males and females. The mention of Stulp et al. likely references a study examining how such conflicts can be manifested in human traits like height, where what is considered sexually attractive or advantageous in one sex may not be in the other. This principle can potentially influence population-level differences in traits like height, as sexual selection pressures differ across cultures. For instance, in some cultures like historical China, certain traits such as small feet in women were prized, whereas in others like the Netherlands, this preference did not exist, which could contribute to differences in average height due to selective mating over generations.
