8 In many primates, including bonnet macaques and rhesus monkeys, the offspring of high-ranking individuals have better fitness and thus an increased rate of survival. It has previously been established that the dominance hierarchy within the species is dependent on the highest ranking female (queen) and her ability to suppress critically important reproductive hormones in male and female sub-dominants. "Female dominance in blue-eyed black lemurs". Thus, individuals with higher social status tend to have greater reproductive success by mating more often and having more resources to invest in the survival of offspring. "Evidence that primer pheromones do not cause social suppression of reproduction in male and female naked mole-rats". Dominant individuals in this case are known as queens and have the obvious advantage of performing reproduction and benefiting from all the tasks performed by their subordinates, the worker caste (foraging, nest maintenance, nest defense, brood care and thermal regulation). Citation needed Hierarchy results as an accumulation of individual interaction, group dynamics, and sharing of resources, therefore group size and composition can affect the dominance decisions of high-ranking individuals and hierarchy type. Similarly, the status of a male Canada goose is determined by the rank of his family. London: Chapman and Hall, 1987 page needed Samuels,.; Silk,.

Subsequent research however, suggests that JH is implicated in the manifestation of dominance, though it only exerts dominance-type effects on certain individuals. The manifestation of intrasexual conflict can be observed in one of two systems. "Reproductive physiology, dominance interactions, and division of labour among bumble bee workers". This reduced fitness due to the alpha position results in individuals maintaining high rank for shorter periods of time and having an overall reduced health and longevity from the physical strain and costs of the position.

That is to say, group members who behave submissively when talking to someone who appears to be in control are better liked, and similarly individuals who display dominant behaviours (e.g., taking charge, issuing orders) are more liked when interacting with docile, subservient individuals. "Influence of insect hormones on the establishment of dominance hierarchies among foundresses of the paper wasp, Polistes gallicus". 46 In some ant species such as the carpenter ant Camponotus floridanus, eggs from queens have a peculiar chemical profile that workers can distinguish from worker laid eggs.
