By Aaron Hums: Recalling the 2011 film The Rise of the Planet of the Apes, Japanese and German researchers used a gene that directs stem cells in the human brain to genetic changes in those of marmoset fruit, according to New York Post.

The study found that the brains of primates injected with ARHGAP11B “became more human-like by developing larger, more advanced neocortexes, the area that controls cognition and language,”

; according to a study published in the journal Science in June. According to images published by the researchers, the modified monkey’s brain has almost doubled in size to about 100 days of pregnancy.

In the end, however, the scientists chose to abort the monkey fetus because of “unpredictable consequences.”

Nevertheless, study author Michael Heide said their hypothesis has been proven: “We have indeed found that the neocortex of the common marmoset brain is enlarged and the brain surface is folded …

The neocortex is the newest part of the brain to evolve – a sign that ARHGAP11B may have caused brain growth during human evolution, researchers say.

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