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 ...

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.

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 ...

Your brain is lying to you right now. Not maliciously, and not because something’s wrong with it. It’s doing exactly what evolution designed it to do, making split-second decisions about the world ...

A part of the brain called the pallium is responsible for many complex functions. In mammals, the pallium is thought to be where the neocortex forms, and gives rise to the cerebral cortex and ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

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 ...

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 ...
