Longer telomeres imparted by older fathers may forestall senescence

Proceedings of the National Academy of Sciences “Delayed paternal age of reproduction in humans is associated with longer telomeres across two generations of descendants”

Science Daily “Offspring of Older Fathers May Live Longer”

What I find fascinating here is the hypothesized adaptive value of this genetic discovery: telomeres may be a molecular mechanism by which the risk of the environment can be gauged, allowing longer-living males to place their bets on offspring who make larger investments in forestalling senescence.
