Discuss the relationship between sexual selection and human reproductive behaviour (8+16 marks)
According to evolutionary psychologists, sexual selection is the choice of characteristics to increase reproductive success. There are two forms of sexual selection; these are inter-sexual selection and intra sexual selection. Inter-sexual selection, also known as ‘mate choice’ is a behaviour seen between sexes to ensure reproductive success. In inter-sexual selection a mate is chosen due to the individual possessing a desired characteristic for reproduction, e.g. a male may pick a female partner with wide hips due to wide hips being associated with successive child birth and a female may pick a male partner with a well-paying job as the man will be able to provide for her offspring.
Intra-sexual selection is the competition within mates, usually males, to ensure that there are successful in passing on their genes for example, today this may involve men competing for a higher paid job in order to be resourceful to women.
