The evolution of the human species is marked by an increase in brain size. Now new research suggests that could be partly ...

What makes the human brain different from that of other primates has long been a question. A new study suggests that the answer may be in a surprising twist of evolutionary fate: one of the brain’s ...

Despite lacking a hippocampus entirely—and having diverged from the mammalian lineage roughly 400 million years ago—larval zebrafish display remarkably precise spatial navigation. Even in small ...

A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that the gut microbiome does more than aid digestion. It may also influence how ...

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 ...

The human brain's soft folds and ridges, arising in early development and continuing through the first 18 months of life, are ...

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 ...

Evidence for the controlled use of fire is rather sketchy prior to one million years ago. Well before this time, human ancestors such as Homo erectus, whose brain size fits between ourselves and the ...

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.
