what did buss and shackleford find?
they found that compared to women, men reported a significantly higher use of threats. e.g threatening to beat up the other man.
Women reported a greater use of verbal possession signals. indicating that there man was taken.
they also found that males with younger female partners put more effort into mate retention tactics.
The findings of buss and shackleford say that males with younger female partners devote more effort into mate retention tactics. this supports the evolutionary theory, why?
Younger women are more desirable and more fertile. This means that they are more likely to become pregnant and therefore the risk of cuckoldry is higher. So to account for this the male must put more effort into mate retention tactics.
