Long human lifespan is due in part to contributions of older adults
Updated : 3 years, 8 months ago IST
Washington [US], July 10 (ANI): According to the long-standing canon in evolutionary biology, natural selection is cruelly selfish, favouring traits that help promote reproductive success. This usually means that the so-called "force" of selection is well equipped to remove harmful mutations
