english: We calculated on the one hand how much energy a primate gets per day from eating raw foods, and on the other hand, how much energy a body of a certain size costs and how much energy a brain of a certain number of neurons costs, and we looked for the combinations of body size and number of brain neurons that a primate could afford if it ate a certain number of hours per day.
non_english: Izračunali smo, koliko energije primati dobijo na dan s surovo hrano, koliko energije porabi telo določene velikosti in koliko energije porabijo možgani z določenim številom nevronov. Iskali smo kombinacije velikosti telesa in števila nevronov, ki bi si jih primati lahko privoščili, če bi določeno število ur dnevno porabili za prehrano.
