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.
Per una banda, vam calcular quanta energia aconsegueix cada dia un primar ingerint menjar cru, i per altra banda, quanta energia necessita un cos d'una certa mida i quanta energia necessita un cervell amb un cert nombre de neurones, i vam buscar les combinacions de mida corporal i nombre de neurones que un primat es pogués permetre si mengés durant un cert nombre d'hores cada dia.
