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 ...

Researchers reveal how gut microbes shape metabolic strategies to fuel larger brains, offering a glimpse into the evolutionary biology of primates. Putative model for microbial influences on the ...

A new study reveals that changes to the gut microbiome can change the way the brain works.

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 ...

A pioneering study provides new evidence that gut microbes vary across primate species and can shape physiology in ways associated with differences in brain size and cognitive function A new study sug ...

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 birds of today descended from the dinosaurs of yore. Researchers have known relatively little, however, about how the bird's brain took shape over tens of millions of years. "Birds are one of the ...
