Evolution of Mammals Reveals New Genes for Longevity.
Summary: Researchers identified 2,000 genes that are linked to human longevity. These genes are linked to biological mechanisms which drive the extension of life in mammal, such as DNA repair, coagulation and immune response.

What factors determine the life expectancy for each species? The field of science has been fascinated by this fundamental, complex question throughout history. According to evolutionary theory, these differences are primarily due to their adaptations in the environment. Life expectancy, for example, is higher in species that are adapted to live in trees, underground or have a large body mass. This is because these adaptations reduce the mortality rate by predators.
