Getting help with the kids slows down ageing in female birds

(University of Groningen) Seychelles warblers live and breed in family groups on the tiny island of Cousin. In each group, a dominant female and male reproduce. When helpers assist the with incubation and feeding of chicks, the dominant female breeders age more slowly and live longer, a study by biologists from the University of Groningen and colleagues shows. The results indicate how cooperative breeding -- which also occurs in other species, including humans -- can increase life span.
