The human brain is without a doubt one of the greatest masterpieces of Evolution. At the same time, researchers from all over the world are trying to understand for decades how the human mind developed over millions of years and more has developed. Equally interesting is how controversial an Experiment, the Chinese and American scientists some years ago in a purpose-built research centre in southern China. Also, you want to find out which genes change the human brain. For infected first, almost a dozen rhesus monkey Embryos with a Virus carrying the human Version of the gene MCPH1. This, you suspect that it plays in the maturation of the nervous system a role. At the end of March, they published in the journal “National Science Review,” first results of their work.

Small achievements, big ambitions

Accordingly, the study involved a geneticist Bing Su and his colleagues agreed that the transgenic monkeys a better short-term memory. In addition, the five primates have shown a shorter response time than that of the wild rhesus monkeys in the control group. From further experiments, the researchers hope to gain even deeper insights as to what makes the people and his brain so unique. In addition, they wanted to focus on neurodegenerative diseases such as Alzheimer’s disease and social behavior disorders, says the study. This will be investigate in other ways very difficult to reports, the researchers at the Kunming Institute of Zoology, the Chinese Academy of Sciences, the University of Carolina, and other facilities. However, the work of the international Teams is not without controversy.

geneticist: “Need to know what we want to know”

back in 2010, warned scientists in front of it, for example, chimpanzees, human brain genes to plant, because these are the people similar. It is disputed whether the monkeys are cared for in the Chinese laboratories is appropriate and whether this type of research should be the future of evolution research. “I don’t think that is a good direction,” says Martin Styner from University of California. “When we do experiments as such, we need to know exactly what we want to know this in order to help the society,” said Styner. This is not the case here. And With five specimens of transgenic monkeys could not come anyway to robust results.

Su and his Team want to explore in spite of the headwinds. For this, he incorporated apparently, it is not the Gene with the name of SRGAP2C in the monkey “”.
