The results showed that the size of our brains can best be explained primarily as a response to ecological pressures, but not exclusively. The best match for modern human brain size came when the ...

In the millions of years of evolution, humans developed strong muscles for hunting and gathering, digestion to get the most nutrients from food and the skills to make tools for all their needs. All of ...

Abstract: Increasing body and brain size constitutes a key macro-evolutionary pattern in the hominin lineage, yet the mechanisms behind these changes remain debated.

Brain organization, not overall size, may be the key evolutionary difference between primate brains, and the key to what gives humans their smarts, new research suggests. In the study, researchers ...

Temporal lobe size changes were linked to early hominins adapting to new environments. Fossil Homo sapiens had smaller temporal lobes relative to brain size, suggesting other brain regions grew for ...

Our Big Brains Have Shrunk. Scientists Might Know Why. The average brain has decreased by the size of a lime in the last few millennia, some researchers say ...

Large brains are energetically costly, especially in primates, where brain size often correlates with increased metabolic demands. Humans, with the largest brain-to-body size among primates, show ...
