In China, a group of researchers genetically altered a dozen of monkeys to duplicate systems of autism. The researchers first conducted this research on mice, but quickly realized that a mouse’s brain is so much different from the human brain that no real results could be tested. The purpose for testing with monkeys was to develop treatment plans and to determine what some of the reasons are for why autism exists today. The monkeys showed signs of autism by displaying repetitive actions, such as walking around in a circle and a lack of socialization (Regalado, 2016). Many researchers questioned if the altered monkeys really had autism, or were they only displaying signs due to the injected gene, which is also known as the MECP2 duplication
