>Birds with bigger genomes survive to a ripe old age
>SIMILAR-sized animals have wildly different genome sizes, but no one has known
>why. Now researchers from Glasgow University have found that, in birds at
>least, genome size is related to longevity.
>In vertebrates, genome size, known as the C-value, varies enormously, from 0.4
>picograms in a pufferfish to 142 pg in the African lungfish. This variation,
>mainly due to differing amounts of non-coding DNA, seems unrelated to an
>animal's complexity, a puzzle dubbed the C-value paradox.
