Human longevity and early reproduction in pre-industrial Sami populations
Abstract Senescence is predicted to be associated with the intensity and timing of reproduction at an earlier age. Here, we examine the phenotypic association between reproduction and post-reproductive survival in three pre-industrial human populations that lived in Northern Scandinavia during 1640–...

Abstract Senescence is predicted to be associated with the intensity and timing of reproduction at an earlier age.
