Did the 12th century B.C.E. -- a time when humans were forging great empires and developing new forms of written text -- coincide with an evolutionary reduction in brain size? Think again, says a UNLV-led team of researchers who refute a hypothesis that's growing increasingly popular among the science community.

Last year's study was sharply criticized by a team of scientists from UNLV, who found many ambiguities in it.

New research has demolished previous theories about evolution, as researchers find that human brains did not shrink 3,000 year ago.

Think again, says a UNLV-led team of researchers who refute a hypothesis that’s growing increasingly popular among the science community.

In previous research released in Frontiers in Ecology and Evolution, experts asserted that the human brain shrank amid a transition to modern urban societies nearly 3,000 years ago.

Our human ancestors roamed the Earth 6 million years ago. However, where is the earliest site containing archaeological evidence of their existence?

The candidates make the Giza pyramids and Stonehenge seem young.

Homo sapiens, commonly referred to as Homo sapiens sapiens, is a highly intelligent species of primate that includes all living humans.
