The operational definition of aggression may be influenced by moral or political opinions. For example, the axiomatic moral vision, called the principle of non-aggression, and the political rules that govern the behavior of one country towards another.  Some forms of aggression may also be punished in competitive sports or in the workplace, and others may not.  Aggressive behavior is associated with adjustment problems and several psychopathological symptoms such as antisocial personality disorder, borderline personality disorder, and intermittent explosive disorder.  In mammals, the hypothalamus and peridotic gray of the central brain are critical areas, as shown by studies in cats, rats and monkeys. These areas of the brain control the expression of behavioral and autonomic components of aggression in these species, including vocalization. Electrical stimulation of the hypothalamus causes aggressive behavior  and the hypothalamus has receptors that help determine levels of aggression based on their interactions with serotonin and vasopressin.  In rodents, activation of neurons experimenting with estrogen receptors in the ventrary part of the ventrotic hypothalamus (VMHvl) was found to trigger aggression in both men and women.   The areas of the midbrain involved in aggression have direct links to the brain nuclei that control these functions and to structures such as the amygdala and prefrontal cortex. Many researchers focus on the brain to explain aggression. Aggressions can also occur to protect themselves or their offspring.  Aggressiveness between groups of animals may also have advantages; For example, hostile behavior can force an animal population into a new area, where the need to adapt to a new environment can lead to increased genetic flexibility.
 In a non-mammalian example of genes related to aggression, the sterile gene in fruit flies is a crucial determinant of certain sexually dimorphic behaviors, and its artificial alteration can lead to the reversal of male and female stereotypes in combat. Many circuits within the neocortic and subcortical structures play a central role in controlling aggressive behavior, depending on the type, and the exact role of signaling pathways may vary depending on the type of trigger or intent.   From this perspective, there are no concepts such as persuasion, aggression, violence and criminal violence that exist as separate buildings, but along a continuum in which moderate levels of aggression are most adaptable.  These scientists do not consider this a trivial difference, as they find that many traditional researchers` measures of aggression can measure outcomes in the lower continuum, at adaptive levels, but they generalize their results to non-adaptive levels of aggression and thus lose accuracy.  In mice, the candidate genes for distinguishing sexual aggressiveness are the sry gene (Y region determining sex), which is located on the Y chromosome, and the Sts gene (steroid sulfatase). The Sts gene encodes the enzyme sulfate sulfate, which is essential for regulating the biosynthesis of neurosteroids. It is expressed in both sexes, correlates with the level of aggressiveness in male mice and increases significantly in women after participation and during lactation, depending on the onset of maternal aggression.  At least one study found a possible epigenic signature (i.e., decreased methylation at a specific cpG location in the promoter region) of the serotonin 5-HT3a receptor associated with maternal aggression in human subjects.  Most behavioural specialists believe that aggression has biological benefits. Aggression can help an animal secure its territory, including resources such as food and water.
Aggression between men often occurs to ensure mating opportunities and leads to the choice of a healthier/stronger animal. .
