Male bighorn sheep are susceptible to local environmental factors in ways that females are not
A new study that looks at lifespan in wild mammals shows that females live substantially longer than males.
The research finds that, on average, females live 18.6% longer than males from the same species.
This is much larger than the well-studied difference between men and women, which is around 8%.
The scientists say the differences in these other mammals are due to a combination of sex-specific traits and local environmental factors.
In every human population, women live longer than men, so much so that nine out of 10 people who live to be 110 years old
