A group of scientists from the University of George Washington (USA) proved that experiments on artificial transformation of a chimpanzee into a more intelligent species of animals should be stopped. In them there is no sense, because the monkey will never be able to pass the path of evolution and become human.
The fact that the human brain being very plastic, able in the shortest possible time to adapt to the new environment. This is not to say the nervous system of chimpanzees and other monkey species.
If the human brain is largely formed after birth under the influence of external factors, the chimpanzee brain and its characteristics are caused by genes, and after the birth, it occurs almost no change.
