"For the first time, scientists have used gene-editing techniques to make monkey brains more humanlike.
...
The team of Chinese scientists edited the human version of a gene called MCPH1 into the macaques. The new gene made the monkeys’ brains develop along a more human-like timeline. The gene-hacked monkeys had better reaction times and enhanced short-term memories compared to their unaltered peers, according to China Daily."
