Describe and evaluate evolutionary explanation of human aggression

The evolutionary explanation of human aggression derives from the changes in species over millions of years. These changes work to increase their chances of survival and reproduction, these changes also known as characteristics are what are naturally selected to be passed onto offspring. Sexual jealousy is one of the main causers of human aggression and is mostly explained by evolution. Sexual jealousy derives from the idea of cuckoldry. Psychology Archer explores the evolutionary idea of paternity uncertainty whereby males are scared of cuckoldry, the name given to a man being unaware of bringing a child that is not his own due to infidelity. When looking at the evolutionary explanation of this, it is shown that men in the past who have avoided cuckoldry were more reproductively successful and thus these characteristics are passed on to offspring. Sexual jealousy is a major motivator of aggressive behaviour; evolutionary theory shows that the aggressive strategies that men employ to keep their partners are adaptive, those whom are more aggressive and use it successfully in a reproductive situation are more successful in acquiring mates and passing on these genes.
