The researchers suggest that this behavioral difference may be rooted in small motivational differences between humans and other species.
In a study of wild field crickets, males are found to protect females from predators, increasing their chances of survival. In exchange, paired males sire more offspring with each partner, suggesting that this 'chivalry' may have evolutionary benefits. The findings challenge traditional interpretations of male guarding behavior.

A UCLA study found that hysterectomized women have higher brain iron levels than non-hysterectomized women, comparable to men. This may explain why men develop age-related neurodegenerative diseases earlier than women. The research suggests that reducing peripheral iron levels could lower disease risk and improve brain health.
