The results of the study show that the two genes act in a finely tuned interplay: one ensures that the progenitor cells of the brain multiply more, while the other causes these cells to transform into ...

Compared to other large primates, humans have unusually big brains. Now, scientists have suggested that the large size of our brains may have been influenced by the gut microbiome. The microbes in the ...

How did humans get such big brains – the answer might lie in the gut. A recent study from Northwestern University in the US is the first to show that gut microbes from different animals can shape ...

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 ...

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 ...

Longer thumbs mean bigger brains, scientists have found—revealing how human hands and minds evolved together. Researchers studied 94 different primate species, including fossils and living animals, to ...

The first hint of a brain developed on Earth around 600 million years ago, and now, some version of the organ can be found in nearly every animal in the world. Humans have the largest brain size ...
