To understand the environmental pressures that shaped human evolution, scientists must first piece together the details of the ancient plant and animal communities that our fossil ancestors lived in over the past 7 million years. Because putting together the puzzle of millions-of-years-old ecosystems is a difficult task, many studies have reconstructed the environments by drawing […]

New research disputes a long-held view that our earliest tool-bearing ancestors contributed to the demise of large mammals in Africa over the last several million years. Instead, the researchers argue that long-term environmental change drove the extinctions, mainly in the form of grassland expansion likely caused by falling atmospheric carbon dioxide (CO2) levels.

An international collaboration, including the Natural History Museum of Utah at the University of Utah, has discovered that early humans in eastern Africa had—by about 320,000 years ago—begun trading with distant groups, using color pigments and manufacturing more sophisticated tools than those of the Early Stone Age. These newly discovered activities approximately date to the […]

On April 20, 2016, University of Utah historical architect Charles Shepherd found something unexpected at an excavation site on Presidents Circle. At first glance in the morning light, he thought it might have been a rock. Closer inspection made it clear, though, that it was a human skull. The skull was just one of more […]

The town of Escalante in southern Utah is no small potatoes when it comes to scientific discovery; a new archaeological finding within its borders may rewrite the story of tuber domestication. Researchers from the Natural History Museum of Utah and Red Butte Garden at the University of Utah have discovered potato starch residues in the […]
