Evolutionary approaches explain human behaviour in terms of adaptiveness and reproductive success. These approaches argue that if a behavioural feature (for example, aggression) has been genetically inherited by one generation from another, then it must have a specific value for human species; it might either help humans adapt better to the environment and survive (natural selection) or might.
There are many theories that try to explain relationships between sexual selection and human reproductive behaviour. Evolutionary theory is one such theory. Evolutionary theory is one such theory. There are many different species in the world which, according to Darwin, all came from one source, e.g. a bacteria or organism.
Discuss the relationship between sexual selection and the human reproductive behaviour (24 Marks) Intrasexual selection is the evolutionary process by which members of one sex (usually males) compete with each other for members of the opposite sex.

For AO1 credit candidates may outline the background to research on sexual selection and human reproductive behaviour in terms of evolutionary theory, selfish gene etc. Also relevant would be a description of the detailed processes involved in sexual selection, including intrasexual (mate competition) and intersexual (mate choice) selection. Other.

The relationship between sexual selection and human reproductive behaviour (AO1) Darwin’s theory of sexual selection is based on the assumption that characteristics are selected because they increase reproductive potential, for example, make the individual more attractive to the opposite sex or more able to compete for mates and so increase the individual’s chance of reproduction.
Natural selection and reproductive behaviour. Natural selection places a premium on the evolution of those physiological, morphological, and behavioral adaptations that will increase the efficiency of the exchange of genetic materials between individuals. Organisms will also evolve mechanisms for sensing whether or not the environment is always permissive for reproduction or if some times are.

Discuss the relationship between sexual selection and human reproductive behaviour. Reproductive success is at the very heart of the evolutionary process. Among early humans, those who failed to mate also failed to become ancestors. For our ancestors, successful mating was a complex business, involving selecting the right mate, out-competing rivals and then engaging in all the right.
Indicative content in the mark scheme is provided as a guide for examiners. It is not intended to be exhaustive and you must credit other valid points. Students do not have to cover all of the points mentioned in the indicative content to reach the highest level of the mark scheme.
The evolutionary explanations for partner preferences, including the relationship between sexual selection and human reproductive behaviour. Factors affecting attraction in romantic relationships: self-disclosure; physical attractiveness, including the matching hypothesis; filter theory, including social demography, similarity in attitudes and complementarity.
Hence one can affirm that social, personality and cognitive aspects determine the differences between masculine and feminine behaviour. To conclude; sex refers to one’s physical anatomy and the sexual orientation of a person is determined by a combination of genetic and hormonal influences. In opposition, gender is shaped by culture, social.
