In conclusion, although this theory provides an adequate explanation of human reproductive behaviour with many supporting research such as Buss this theory can also be described as deterministic a it states that all men and woman possess these characteristics.

For example, a physically stronger and larger male will be able to fight off his competitors for access to the female, so he will produce physically stronger sons.

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.
