The cerebral cortex, the brain’s outermost region responsible for higher cognitive functions, depends on a highly ordered, ...

You are a child who grew up. The inevitability of a child’s growth is both celebrated and mourned. Under normal circumstances, parents can do little but stand back and watch as shoe sizes climb, ...

Add Yahoo as a preferred source to see more of our stories on Google. Hobbits are exceptions to the rule that older ancient humans had proportionally larger wisdom teeth and smaller brains. Jim Watson ...

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 ...

Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold. As a rule, mammals and birds have the largest brains in relation to their body size, ...

Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found. The study ...

One of the defining features of human evolution is the steady expansion of our brains. New findings suggest this growth may be partly linked to higher levels of estrogen before birth. Surprisingly, a ...

Next time you're trying to size someone up, take a look at their thumbs. If they have particularly long thumbs, they might be especially clever, a new study suggests. Scientists at the University of ...

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 ...

Over the last decades, research has proven that aging isn’t just about our years in birthdays. Instead, we may be better served by knowing how organs and cells have handled those years. This powerful ...

Scientists have long tried to understand the human brain by comparing it to other primates. Researchers are still trying to understand what makes our brain different from our closest relatives. Our ...
