The data showed the genes in the human brain evolved much faster than those of the other species. Once this genomic evidence was acquired, Lahn and his team decided to find the specific gene or genes that allowed for or even controlled this rapid evolution. Two genes were found to control the size of the human brain as it develops.
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [40] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
Furthermore, the changes in the structure of human brains may be even more significant than the increase in size. [142] [143] [144] [53] Fossilized skulls shows the brain size in early humans fell within the range of modern humans 300,000 years ago, but only got its present-day brain shape between 100,000 and 35,000 years ago.

Scientists at the University of California, San Francisco have developed a bilingual brain implant that uses artificial intelligence to help a stroke survivor communicate in Spanish and English ...
Although the evolution and function of the human cerebral cortex is still shrouded in mystery, we know that it is the most dramatically changed part of the brain during recent evolution. The reptilian brain, 300 million years ago, was made for all our basic urges and instincts like fighting, reproducing, and mating.
The human brain can feature in science fiction, with themes such as brain transplants and cyborgs (beings with features like partly artificial brains). [225] The 1942 science-fiction book (adapted three times for the cinema) Donovan's Brain tells the tale of an isolated brain kept alive in vitro , gradually taking over the personality of the ...
The brain is the most well-protected organ in the human body, but it has a surprisingly high amount of microplastic pollution, according to a paper published in Nature Medicine on Monday.
