english: 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.
non_english: Toen stierven de dinosaurussen uit, en daarbij nog eens 75 procent van alle dier- en plantensoorten. Toen namen de zoogdieren hun ecologische niches over. Mocht de evolutie kunnen denken, zou ze zeggen: "Hmm, die neocortex is best goed spul, we gaan die wat laten groeien.”
