Making monkeys more smart and human-like, scientists have used gene-editing to insert human brain gene in a monkey. For the first time, a team of Chinese scientists made use of gene-editing techniques to make monkey brains more human-like. By the end, the monkeys, rhesus macaques, got smarter and had superior memories as compared to the unaltered monkeys. Researchers edited the human version of a gene known as ‘MCPH1’ into the macaques. The gene made the monkeys’ brain develop along a more human-like timeline. The gene-hacked monkeys showed better reaction times and improved short-term memories in comparison to their unaltered peers,...
