Are genes becoming more important with increasing age?

15.11.2006 admin

I found an apparent paradox between two studies. John Whitfield did a twin study in Australia and concluded that shared environmental effects decreased with age (from about 50% to 10%) while additive genetic effects increased. The new Sardinian study found higher heritabilities among younger individuals and explained that by an increase of environmental insults with age. Nice said, but who is right?
