Evolutionary explanations of reproductive behaviour

AO1/AO2

• Males seek females at peak fertility. BUSS's cross cultural study of 37 cultures and found that in all of them males preferred mates that were younger. He also found that on averages, males would choose a mate that was in her mid 20's (close to prime of physical attractiveness and relative youth, more than females. This supports the theory of evolution as it provides evidence for males looking to mate with females in their fertility prime.
• An issue with the theory is that it is deterministic. By suggesting human reproductive behavior is
• The evolutionary theory also states that males should be more jealous in relationships than females as they have a greater uncertainty of parenthood. Because of this, they should be more concerned with their partner's infidelity in order to maximize the chances that it is their genes being passed on. Further supporting evidence for the evolutionary theory comes from another study by BUSS. Results from this study showed that males exhibit more signs of stress if they imagine their partner being sexually unfaithful than females did.
