A sweeping new study exploring lifespan across mammals reveals that female animals tend to live longer than males—on average 18.6% more in the wild.

 

Researchers analysed age- and sex-specific mortality data from 134 populations across 101 mammal species to reach this conclusion. 

 

This female advantage is not simply due to differences in ageing rates; it's driven by lower mortality risk for females throughout adulthood. Potential mechanisms include genetic factors (like the “unguarded X” hypothesis), hormonal and mitochondrial resilience, and the different pressures of reproduction and behaviour. 

 

Behaviour also plays a role. In many species, males engage in risky behaviours such as competition, conflict, or extravagant displays that increase mortality. Parental investment differences and ecological stressors further contribute to lifespan gaps. 

 

 

 

While humans also show a female longevity advantage (around 7–8% on average), the disparity in many wild mammals is much larger.

 

The new research challenges simplistic explanations and pushes us to consider how sex, genetics, behaviour and environment conspire in shaping lifespan.

 

 

 

Key Takeaways

 

In 60 % of studied mammal populations, females live longer than males—mean advantage ~18.6 %. 

 

The lifespan gap stems not from slower ageing in females, but consistently lower mortality risk during adulthood. 

 

Genetic safeguards (e.g. double X chromosomes), hormonal & mitochondrial resilience, plus male behavioural risks all likely contribute to sex differences in longevity.

Hold my beer…….watch this…….my car is faster wanna race….to name a few and that’s not even touching on work.

What! This article suggests confirms that there are only two genders.  No mention whatsoever of non-binary chimpanzees and their life expectancy.

 

Heresy !!!!!

Are there gay animals?lol ?

Females nag men to death!
