    ‘Humans were not centre stage’: how ancient cave art puts us in our place
    In our self-obsessed age, the anonymous, mysterious cave art of our ancient ancestors is exhilarating. By Barbara Ehrenreich

    In 1940, four teenage boys stumbled, almost literally, from German-occupied France into the Paleolithic age. As the story goes – and there are many versions of it – they had been taking a walk in the woods near the town of Montignac when the dog accompanying them suddenly disappeared. A quick search revealed that their animal companion had fallen into a hole in the ground, so – in the spirit of Tintin, with whom they were probably familiar – the boys made the perilous 15-metre descent to find it. They found the dog and much more, especially on return visits illuminated with paraffin lamps. The hole led to a cave, the walls and ceilings of which were covered with brightly coloured paintings of animals unknown to the 20th-century Dordogne – bison, aurochs and lions. One of the boys later reported that, stunned and elated, they began to dart around the cave like “a band of savages doing a war dance”. Another recalled that the painted animals in the flickering light of the boys’ lamps seemed to be moving. “We were completely crazy,” yet another said, although the build-up of carbon dioxide in a poorly ventilated cave may have had something to do with that.

    This was the famous and touristically magnetic Lascaux cave, which eventually had to be closed to visitors lest their exhalations spoil the artwork. Today, almost a century later, we know that Lascaux is part of a global phenomenon, originally referred to as “decorated caves”. They have been found on every continent except Antarctica – at least 350 of them in Europe alone, thanks to the cave-rich Pyrenees – with the most recent discoveries in Borneo (2018) andCroatia (April 2019). Uncannily, given the distances that separate them, all are adorned with similar decorations: handprints or stencils of human hands, abstract designs containing dots and crosshatched lines, and large animals, both carnivores and herbivores, most of them now extinct. Not all of these images appear in each of the decorated caves – some feature only handprints or megafauna. Scholars of paleoarcheology infer that the paintings were made by our distant ancestors, although the caves contain no depictions of humans doing any kind of painting.

          • 'Ghost' DNA In West Africans Complicates Story Of Human Origins

            About 50,000 years ago, ancient humans in what is now West Africa apparently procreated with another group of ancient humans that scientists didn't know existed.

            There aren't any bones or ancient DNA to prove it, but researchers say the evidence is in the genes of modern West Africans. They analyzed genetic material from hundreds of people from Nigeria and Sierra Leone and found signals of what they call "ghost" DNA from an unknown ancestor.

            Our own species — Homo sapiens — lived alongside other groups that split off from the same genetic family tree at different times. And there's plenty of evidence from other parts of the world that early humans had sex with other hominins, like Neanderthals.

            That's why Neanderthal genes are present in humans today, in people of European and Asian descent. Homo sapiens also mated with another group, the Denisovans, and those genes are found in people from Oceania.

            The findings on ghost DNA, published in the journal Science Advances, further complicate the picture of how Homo sapiens — or modern humans — evolved away from other human relatives. "It's almost certainly the case that the story is incredibly complex and complicated and we have kind of these initial hints about the complexity," says Sriram Sankararaman, a computational biologist at UCLA.
            The scientists think the interbreeding happened about 50,000 years ago, roughly the same time that Neanderthals were breeding with modern humans elsewhere in the world. It's not clear whether there was a single interbreeding "event," though, or whether it happened over an extended period of time.

            The unknown group "appears to have split off from the ancestors of modern humans a little before when Neanderthals split off from our ancestors," he says.
