(The Sun) – Scientists have made monkeys’ brains bigger by splicing them with human genes in an experiment reminiscent of The Planet of the Apes. Experts took the gene known as ARHGAP11B – which directs stem cells in the human brain – and placed it into the brains of common marmosets.
The experiment ended up with the monkey fetuses having larger, more advanced, and more-human like brains, according to the study published in Science. Scientists however opted to abort the fetus due to possible “unforeseen consequences”. It echoes the plot of the Planet of the Apes movies series, in which a new race of genetically modified intelligent primates takes over the Earth.
Mankind carries out experiments on apes to make them smarter, only for human society to them collapse as the creatures rise up against them. Humans are then left living in a primitive and tribal society which is hunted and caged by the very creatures they helped create.
The Planck Institute of Molecular Cell Biology and Genetics in Germany and the Central Institute for Experimental Animals in Japan carried out the new experiments. Scientists said the test monkeys were left with larger neocortexes – the area of the brain linked to functions such as cognition and language.
It is the newest part of the brain to evolve and is one of the key elements that makes humans unique. Pictures published by the scientists show a comparison of a normal monkey brain, and the engorged one after being pumped with ARHGAP11B. READ MORE
