Tutkimus kertoo yhden syyn miksi ihminen eroaa muista kädellisistä henkisiltä ominaisuuksilta.
>We show that the morphology of the human cerebral cortex is substantially less genetically heritable than in chimpanzees and therefore is more responsive to molding by environmental influences. This anatomical property of increased plasticity, which is likely related to the human pattern of development, may underlie our species’ capacity for cultural evolution.

Tuo ero on kuitenkin mitä ilmeisimmin syntynyt geneettisellä mutaatiolla giologisessa evoluutiossa. Sen varaan on sitten kerrostunut valtava määrä kumuloitunutta oppimista kulttuurievoluution tuotoksina ja käyttövoimana.
Lisää juttua aivoista.
