Female of the species always outlives the males
Researchers examined age-specific mortality estimates for a widely diverse group of 101 species.
On average, females live 18.6% longer than males from the same species.
Much larger than the difference between men and women of around 8%.
9 out of 10 people who live to be 110 years old are female.
Differences in mammals due to a combination of sex-specific genetics and local environmental factors.
Where natural resources were consistently available there was little difference in lifespan.
