An international team of researchers has discovered two networks of genes across all types of rockfish that may help to explain the differences in longevity in different species. In their paper published in the journal Science ...
Natural selection has produced mammals that age at dramatically different rates. Take, for example, naked mole rats and mice; the former can live up to 41 years, nearly ten times as long as similar-size rodents such as mice.
