Researchers are splitting human genes into monkey brains to make them bigger and smarter

By Aaron Humes: Reminiscent of the 2011 film, “Rise of the Planet of the Apes,” Japanese and German researchers used a gene that directs stem cells in the human brain to genetically alter them from marmoset fetuses, according to New York Post.

The study showed that the brain of primates injected with ARHGAP11B “became more human by developing larger, more advanced neocortexes – the area that controls cognition and language,”

; according to the study published in the journal Science in June. According to images released by the researchers, the modified monkey brain almost doubles in size around 100 days of pregnancy.

In the end, however, researchers chose to discontinue the monkey fetuses because of “unpredictable consequences.”

Nevertheless, study author Michael Heide said that their hypothesis was proven: “We actually found that the neocortex in the common marmoset brain was enlarged and the brain surface folded …”

The neocortex is the newest part of the brain that has evolved – a sign that ARHGAP11B may have caused brain growth during human development, the researchers said.

The study was conducted by the Planck Institute of Molecular Cell Biology and Genetics in Germany and the Central Institute for Experimental Animals in Japan
