The evolutionary history of the human brain shows primarily a gradually bigger brain relative to body size during the evolutionary path from early primates to hominins and finally to Homo sapiens. This trend that has led to the present day human brain size indicates that there has been a 2-3 factor increase in size over the past 3 million years ...
The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately seven million years, [ 1 ] from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago.
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 ...
Vision allows humans to process the world surrounding them to a certain extent. Through the wavelengths of light, the human brain can associate them to a specific event. Although the brain obviously perceives its surroundings at a specific moment, the brain equally predicts the upcoming changes in the environment.
A study last year suggested that our ability to store information externally in our social groups meant we no longer needed large brains - and our brains shrunk accordingly.
A new analysis of the 25-foot-long (7.6-meter-long) bridge inside Genovesa Cave has revealed that humans lived on Mallorca, one of the largest islands in the Mediterranean, much earlier than ...
