Until Homo floresiensis was discovered, scientists assumed that the evolution of the human lineage was defined by bigger and bigger brains. Via a process called encephalization, human brains evolved ...

The natural and the social world shaped the evolution of each. Knowing whom to invite to dinner is as important as knowing how to cook.

The brain is the most complex organ in the human body. Now, a new study has brought us closer to understanding some of its evolution. It shows that human brains decreased in size approximately 3,000 ...

The human brain, weighing roughly three pounds, runs the full spectrum of cognition, motor control, sensory processing, and emotional regulation on a power budget estimated at 10 to 20 watts. That is ...

Brain scientists have long debated when, and how strongly, sex starts to shape the human brain. A growing body of imaging work now points to a clear answer: measurable differences in brain size and ...

The coordinated expansion of these brain regions accounts for much of the variation in brain size across primate species. Given their role in fine motor skills and spatial processing, these areas were ...

What unique processes conspire to create a healthy, functional human brain? How can we be so genetically similar to, say, chimpanzees, and yet be light-years more sophisticated cognitively and ...

A new study suggests AI systems could be a lot more efficient. Researchers were able to shrink an AI vision model to 1/1000th ...
