Human longevity within an evolutionary perspective: The peculiar paradigm of a postreproductive genetics

2008

The data we collected on the genetics of human longevity, mostly resulting from studies on centenarians, indicate that: (1) centenarians and long-living sib-pairs are a good choice for the study of human longevity, because they represent an extreme phenotype, i.e., the survival tail of the population who escaped neonatal mortality, pre-antibiotic era illnesses, and fatal outcomes of age-related complex diseases. (2) The model of centenarians is not simply an additional model with respect to well-studied organisms, and the study of humans has revealed characteristics of ageing and longevity (geographical and sex differences, role of antigenic load and inflammation, role of mtDNA variants) wh…
