In total, the Neanderthals endured for an astonishing 350,000 years, until we lose sight of them – or, at least their fossils and artefacts – somewhere around 40 ka. So far, so dizzying. But it‘s not just time: Neanderthals also spread across a remarkably vast swathe of space. More Eurasian than European, they lived from north Wales across to the borders of China, and southwards to the fringes of Arabia‘s deserts.
