That's when the dinosaurs went extinct, that's when 75 percent of the animal and plant species went extinct, and that's when mammals overtook their ecological niche, and to anthropomorphize, biological evolution said, "Hmm, this neocortex is pretty good stuff," and it began to grow it.
Tada su izumrli dinosauri, tada je 75 posto životinjskih i biljnih vrsta izumrlo i tada su sisavci zauzeli svoju ekološku nišu i da antropomorfiziramo,  biološka evolucija je rekla: "Hm, ovaj neokorteks je odlična stvar", i počela ga je razvijati.
