english: In this picture, I've put a bush with a center branching out in all directions, because if you look at the edges of the tree of life, every existing species at the tips of those branches has succeeded in evolutionary terms: it has survived; it has demonstrated a fitness to its environment.
non_english: Na tento obrázok som dal krík doprostred a vetví sa na každú stranu, pretože ak sa pozriete na okraje stromu života, každý jestvujúci druh na konci tých vetvičiek v evolučnom zmysle uspel: prežil; dokázal, že sa do tohto prostredia hodí.
