english: So the reason why the human brain costs so much energy is simply because it has a huge number of neurons, and because we are primates with many more neurons for a given body size than any other animal, the relative cost of our brain is large, but just because we're primates, not because we're special.
non_english: Razlog, da človeški možgani porabijo toliko energije, je v tem, da imajo  veliko število nevronov. Ker smo primati z dosti več nevroni glede na velikost telesa kot katerakoli druga žival, je tudi povprečna poraba možganov velika, toda le zato, ker smo primati, in ne, ker smo posebni.
