Until Homo floresiensis was discovered, scientists assumed that the evolution of the human lineage was defined by bigger and bigger brains. Via a process called encephalization, human brains evolved ...

Modern humans are evolutionary survivors, thriving generation after generation while our ancient relatives died out. Now, new research into our brain chemistry suggests that an enzyme unique to Homo ...

UC San Diego researchers have found high levels of lead in the teeth of both Neanderthals (left) and modern humans (right). However, a gene mutation may have protected modern human brains, allowing ...

A new study in the lab of Jason Stein, Ph.D., modeled brain development in a dish to identify cells and genes that influence ...
