Mass extinctions have served as huge reset buttons that dramatically changed the diversity of species found in oceans all over the world,

ffxiv gil, Scientists had once thought species diversity could help buffer a group of animals from such die-offs,
ffxiv gil, either keeping them from heading toward extinction or helping them to bounce back.
wow gold, But having many diverse species also proved no guarantee of future success for any one group of animals, given that mass extinctions more or less wiped the slate clean,
