But if succeeding tests will yield the same results, there goes another myth... and this is a really, really good one indeed! Read on... ----- Posted: 12 June 2012 WASHINGTON : The offspring of fathers and grandfathers who reproduced later in life could enjoy life-extending genetic benefits, including being able to father children at an older age, a new study suggests. Researchers at Northwestern University believe the process represents an unusually rapid evolutionary adaptation in which telomeres -- DNA found at the ends of chromosomes -- lengthen, which is thought to promote healthy aging. "If your father and grandfather were able to live and reproduce at a later age, this might predict that you yourself live in an environment that is somewhat similar -- an environment with less accidental deaths or in which men are only able to find a partner at later ages,...
