Scientists splice human genes into monkey brains to make them bigger, smarter

What could go wrong?

Scientists made monkey brains double in size by splicing them with human genes in a “Planet of the Apes”-style experiment.

During the study, Japanese and German researchers injected a gene called ARHGAP11B — which directs stem cells in the human brain — into the dark matter of marmoset fetuses, according to a release about the research.

They found that the primates’ brains soon became more human-like 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 brains nearly doubled in size at around 100 days into gestation.
