How did humans become smarter than other apes? One out of the box idea suggests that that it could be possible due to a slowdown of our brain growth during fetal development. Published in the Nature it entails of growing embryonic-like stem cells in a dish and coaxing them to turn into nervous system cells until they form pea-sized three-dimensional clumps called organoids. These “mini brains” seem to replicate real neuron behaviour more closely than when brain cells are grown in a flat layer. Researchers used stem cells from humans, chimpanzees and macaque monkeys to make mini brains for each species and observed that after four months, the nerve cells in the chimp and monkey organoids were more mature.
