=== Benefits ===
 
Being subordinate offers a number of benefits. Subordination is beneficial in agonistic conflicts where rank predicts the outcome of a fight. Less injury will occur if subordinate individuals avoid fighting with higher-ranking individuals who would win a large percentage of the time — knowledgetime—knowledge of the pecking order keeps both parties from incurring the costs of a prolonged fight. In hens, it has been observed that both dominants and subordinates benefit from a stable hierarchical environment, because fewer challenges means more resources can be dedicated to laying eggs. In groups of highly related individuals, kin selection may influence the stability of hierarchical dominance. A subordinate individual closely related to the dominant individual may benefit more genetically by assisting the dominant individual to pass on their genes.<ref>{{cite book |last1=Pusey |first1=A.

Alpha male [[baboon|savanna baboons]] have high levels of [[testosterone]] and stress; over a long period of time, this can lead to decreased fitness. The lowest-ranking males also had high stress levels, suggesting that it is the beta males that gain the most fitness, avoiding stress but receiving some of the benefits of moderate rank.<ref name= "Gesquiere"/> The mating tactics of savanna baboons are correlated with their age. Older, subordinate males form alliances to combat higher-ranking males and get access to females.<ref>{{cite journal |last1=Noe |first1=R. |last2= Sluijter |first2=A.
