One of the defining features of human evolution is the steady expansion of our brains. New findings suggest this growth may be partly linked to higher levels of estrogen before birth. Surprisingly, a ...

Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of index and ring fingers — a ...

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.

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 ...

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 ...

For more than a century, scientists have treated the brain as the undisputed command center of human evolution, with the rest of the body cast in supporting roles. A wave of new microbiome research is ...

Researchers have used a new human reference genome, which includes many duplicated and repeat sequences left out of the original human genome draft, to identify genes that make the human brain ...

Brain freeze — the sharp, seconds-long headache we get from ingesting something cold — is rooted in the way our brain senses ...

The microorganisms in our gastrointestinal tract–the gut microbiome can exert a profound influence on the human body, and scientists are learning more about exactly how certain microbes can impact us.

Scientists find clue to human brain evolution in finger length: Study ...
