Explain evolutionary influences on aggression. - Scottish Highers Psychology - Question 8(a) - 2019

Evolutionary influences on aggression can be explained through several key concepts.

First, aggression is often viewed as a survival trait that enhances reproductive success. According to evolutionary theory, individuals who exhibit aggressive behaviors may be more successful in competition for resources, such as food and territory, which in turn can secure their survival and that of their offspring. This perspective posits that aggressive individuals can ensure better access to essential resources, enabling them to protect their kin and increasing the likelihood of passing on their genes.

Secondly, aggression plays a role in mate selection. Males who demonstrate aggression may be perceived as having desirable traits such as strength and dominance. These traits can make them more attractive to potential mates, as they signal the ability to provide protection and resources. Consequently, aggressive males may have a better chance of mating and ensuring the propagation of their genetic material.

Furthermore, the concept of sexual selection highlights that aggressive behaviors can serve adaptive purposes. Aggression may help individuals defend their mates from rivals and thus maintain their reproductive opportunities.

In summary, evolutionary influences on aggression underscore its importance in survival and reproductive strategies, indicating that aggression is an adaptive behavior shaped by the pressures of natural and sexual selection.
