Where did the first people come from? The case for a coastal migration from southern Africa

A coastal migration up and out of Africa was more likely to succeed than an overland journey.

Tiny cut marks on animal bone fossils reveal that human ancestors were in Romania 1.95 million years ago

Researchers reexamining fossils identified telltale marks made by human ancestors cutting meat from bones. The discovery pushes back the date hominins started living in Europe by 200,000 years.
The fossil deposits at the La Brea Tar Pits in Los Angeles have well-preserved remains of many prehistoric animals that got stuck in natural asphalt seeps over the past 60,000 years. Cullen Townsend, courtesy of NHMLAC

A changing climate, growing human populations and widespread fires contributed to the last major extinction event − can we prevent another?

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 DNA preserved in the tooth tartar of human fossils encodes microbial metabolites that could be the next antibiotic. Werner/Siemens Foundation

Reconstructing ancient bacterial genomes can revive previously unknown molecules – offering a potential source for new antibiotics

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.

How climate change is erasing the world’s oldest rock art

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.
These fossil trackways resemble the tracks left by flamingos today, but are bigger. Just above the scale bar one can see (more faintly) the ‘tramline traces’ made by the ancient birds’ stomping action. Charles Helm

Fossil tracks reveal which birds once roamed South Africa’s Cape south coast

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.
