A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that ...

Gut Microbes may have helped fuel the evolution of large human brains, shaping brain metabolism and gene activity, new ...

The microorganisms in our gastrointestinal tract-the gut microbiome, can exert a profound influence on the human body, and ...

Human evolution is a long and winding tale that goes back millions of years, but one aspect of our anatomy shaped up quickly compared to other mammals: our large brains and flat faces. As these ...

A pioneering study provides new evidence that gut microbes vary across primate species and can shape physiology in ways ...

By transplanting gut microbes from humans, squirrel monkeys and macaques into germ-free mice, scientists reveal that microbiome composition directly influences brain gene expression.

The placenta and the hormones it produces may have played a crucial role in the evolution of the human brain, while also leading to the behavioral traits that have made human societies able to thrive ...

Researchers discovered that autism’s prevalence may be linked to human brain evolution. Specific neurons in the outer brain evolved rapidly, and autism-linked genes changed under natural selection.

A groundbreaking international study changes the view that exposure to the toxic metal lead is largely a post-industrial phenomenon. The research reveals that our human ancestors were periodically ...
