english: Our brain weighs between 1.2 and 1.5 kilos, but elephant brains weigh between four and five kilos, and whale brains can weigh up to nine kilos, which is why scientists used to resort to saying that our brain must be special to explain our cognitive abilities.
non_english: Naši možgani tehtajo med 1,2 in 1,5 kilograma, slonovi možgani med 4 in 5 kilogrami in kitovi možgani tudi do 9 kilogramov, zato so se znanstveniki  zatekali k trditvi, da so naši možgani nekaj posebnega. Tako so lahko razložili  naše kognitivne zmožnosti.
