Acheulean Toolmakers Chose Their Stone with Surprising Precision
Geochemical analysis of 780,000-year-old stone tools from Israel suggests Acheulean (or Acheulian) hominins repeatedly sought specific basalt sources, revealing sophisticated planning and deep knowledge of their landscape.

Red Lines Dismissed As Geological Accident Turn Out To Be Britain’s Oldest Rock Art
A century after they were discovered, they're finally getting some appreciation.
If I had a hammer... it might actually be a rhino tooth
One way archaeologists learn how ancient people, including Neanderthals, did things is to attempt to do those things themselves, a process called experimental archaeology. Normally, that involves making stone tools, butchering deer, or distilling birch tar. But in a new study, it meant doing very destructive things to teeth from one of the world’s most carefully protected animals.
That's because the archeologists suspected that Neanderthals once used rhino teeth as tools. By using the teeth to make stone tools, the researchers demonstrated that Neanderthals probably did the same thing, adding to what we know about the wide range of items in their toolkits.
We need to hit some rhino teeth with rocks for science
Some Neanderthal archaeological sites in Europe and Asia seem to have many more rhinoceros teeth lying around than you’d expect. We know Neanderthals hunted a now-extinct species of rhinoceros in Europe and eastern Asia, but the people who had inhabited these sites looked like they had been collecting rhino teeth for some reason.

Largest Known Wild Chimpanzee Community Breaks Apart After Decades of Unity
Wild chimpanzees in Uganda split into two separate communities and later engaged in deadly attacks against each other. Researchers believe the conflict shows how social relationships alone can fuel polarization and violence. The world’s largest known community of wild chimpanzees has permanently divided into two separate groups. Researchers from the University of Texas at Austin [...]
Giant Stone Urns Hint at the Death Rites of a Lost People in Laos
Thousands of mysterious containers lie scattered across northern Laos. These “death jars” may have provided a form of communal interment, archaeologists reported.
Upright Walking and Larger Brains May Explain Why 90% of Humans Favor Their Right Hand
New research from the University of Oxford and the University of Reading suggests bipedalism and expanding brain size helped drive the overwhelming dominance of right-handedness in humans.
