Brain size has only a limited link to intelligence, which is shaped more by neural wiring, structure, and processing efficiency ...

Behavior that we’d consider intelligent is oddly widespread in the animal kingdom. Animals with very different brains from ours—a species of octopus and various birds—engage with tools, to give just ...

Humans owe our impressive intellect to our large brains, which are unusually sophisticated thanks to evolution. The first surge in our brain size occurred between 2 million and 800,000 years ago, when ...

Genes play a powerful role in shaping your health—you won’t believe how your DNA influences everything from ADHD to Parkinson’s disease. Here’s what groundbreaking research reveals about the ...

Human brains have been steadily growing through the decades, and that may be lowering the risk of dementia. A new study out of UC Davis Health found that people born in the 1970s had brain volumes ...

The largest animals do not have proportionally bigger brains—with humans bucking this trend—a study published in Nature Ecology & Evolution has revealed. Researchers at the University of Reading and ...

Scientists have long believed that, generally speaking, the bigger an animal is, the bigger its brain. But our recent study challenges the nature of that linear view and reveals new insights about how ...

The skull of a dog and the 3D model of the brain in it based on high-resolution CT-scanning. A recent study by László Zsolt Garamszegi from the Institute of Ecology and Botany, Centre for Ecological ...

The largest animals do not have proportionally bigger brains -- with humans bucking this trend -- a new study has revealed. The largest animals do not have proportionally bigger brains -- with humans ...
