Summary:
- The article discusses a study that examined the lifespan differences between males and females across over 1,000 different species, including humans.
- The study found that in the majority of species, females tend to live longer than males, and this pattern has been observed throughout evolutionary history.
- The researchers suggest that this lifespan difference is likely due to evolutionary pressures that favor longer lifespans in females, as they play a crucial role in the reproduction and survival of the species.
