Telomeres and longevity: testing an evolutionary hypothesis.
Identifying mechanisms that underlie variation in adult survivorship provide insight into the evolution of life history strategies and phenotypic variation in longevity. There is accumulating evidence that shortening telomeres, the protective caps at the ends of chromosomes, play an important role in individual variation in longevity. Given that telomeres generally shorten with age, it was surp...
متن کاملTelomeres and longevity
the basic elements of telomere biology are very similar across many taxa [1], there is diversity among species, and among tissues, in telomere dynamics. Not surprisingly, given that species differ in many other relevant aspects of their biology, including the pattern of activity of the telomere-restoring enzyme telomerase simple comparisons of average telomere length across species do not map d...
متن کاملTelomeres, Atherosclerosis, and Human Longevity
Human telomere length, as expressed in leukocytes, is strongly fashioned by heritability. A number of genes that explain some of the inter-individual variation in leukocyte telomere length have already been identified. Leukocyte telomere length is longer in women than in men and in African Americans than in whites of european descent. in addition, offspring of older fathers display a longer leu...
متن کاملDoes Longevity Cause Growth? A Theoretical Critique∗
This paper challenges conventional wisdom by arguing that greater longevity may have contributed less than previously thought for the significant accumulation of human capital during the transition from stagnation to growth. This is because when parents make choices over the quantity and quality of their offspring, greater longevity positively affects not only the returns to quality but also th...
