The larger size of our brain is a defining factor of what makes a human indeed human.
Modern research has shown that the large size of the human brain is due to one specific gene, called ARHGAP11B.
This gene is found only in humans and triggers an increased production of brain stem cells which makes the brain bigger.
This has been discovered by the researchers at the Max Planck Institute
of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden.
Researchers have inserted the human-specific gene to the undeveloped fetuses of marmosets, which in turn caused the monkey’s brains to grow larger.

You can watch fetal marmoset brains grew larger than usual with the help of a human-specific gene.
The marmoset fetuses were delivered by c-section after 100 days, 50 days before the normal birth date.
The experiment was stopped at this stage since production of genetically
modified monkey's ethically immoral and potentially unsafe for humanity.
