english: Instead, random genetic mutations cause some giraffes to be born with longer necks, and that gives them a better chance to survive than the ones who weren't so lucky, which brings us to "survival of the fittest".
non_english: Zapravo, slučajne genetske mutacije dovode to toga da se neke žirafe rađaju sa dužim vratovima i to im daje bolje šanse da prežive nego one koje nisu imale toliko sreće, što nas dovodi do "preživljavanje najsposobnijih".
