New findings from the La Brea Tar Pits in southern California suggest human-caused wildfires in the region, along with a warming climate, led to the loss of most of the area’s large mammals.
Ancient microbes likely produced natural products their descendants today do not. Tapping into this lost chemical diversity could offer a potential source of new drugs.
The ancient cave paintings have only begun to tell us about the lives of the earliest people who lived in Australasia. The art is disappearing just as we are beginning to understand its significance.
Several theories have suggested either humans, climate change or both drove megafauna extinctions in Southeast Asia. Our newest work suggests otherwise.
One avian track, probably made by a large gull or a small goose, was found in sediments that have been dated to about 400,000 years. That makes it the oldest avian track reported from southern Africa.
Given that we know humans moved across these landscapes, we wondered whether there might also be evidence of other forms of human activity on these surfaces of sand.
The Indian summer monsoon rainfall affects the lives of over a billion people. By looking at how prehistoric climate changes affected it, scientists can contribute to its future prediction.
A team of archaeologists strived to improve the reproducibility of their results, influencing their choices in the field, in the lab and during data analysis.
Large birds once lived across Australia, only to become extinct around the time that giant marsupials and other megafauna died out during the Pleistocene “ice ages”.
