english: They were evolved for a world in which people lived in very small groups, rarely met anybody who was terribly different from themselves, had rather short lives in which there were few choices and the highest priority was to eat and mate today.
non_english: Boli vyvinuté pre svet, kde ľudia žili vo veľmi malých skupinách, málokedy stretli niekoho príliš odlišného, mali relatívne krátky život, v ktorom sa rozhodovali len zriedka a ich najvyššou prioritou bolo jesť a páriť sa a to čím skôr.
