A seven hundred thousand-year-old elephant molar from the Gesher Benot Ya'aqov site in northern Israel shows that early humans lived alongside giant forest elephants in a landscape of forests and swamps that has now completely vanished, according to research reported on October 9. The tooth belonged to Palaeoloxodon antiquus, a forest elephant that could stand more than four metres tall, and stone tools found near the remains show humans shared the same ground.
The reconstruction works from two kinds of evidence in one object. CT scans and wear patterns on the molar, together with chemical traces in its enamel, record what the animal ate and the environment it moved through, while pollen preserved in the site deposits rebuilds the vegetation around it. The result is a water-rich corridor, interpreted by the researchers as a possible migration route between Africa and Eurasia, populated by animals considerably larger than anything in the region today. A single molar cannot carry a whole landscape on its own, and it is not being asked to: it is the latest specimen in a long-studied site, adding diet and environment data to a record built from tools, sediments and earlier finds. That is how palaeontology normally advances, one dated, analysed object at a time.
Science advances by claims that survive checking. The Science desk reads for the structure of the evidence, what was measured, in what system, with what uncertainty, and reports preliminary findings as preliminary. That caution is not a lack of enthusiasm. It is how the desk protects the reader's trust for the findings that turn out, on replication, to be real.
Where early humans lived, what they lived beside and which corridors they travelled are the basic questions of human origins, and they are answered environmentally. A green, watered route out of Africa, used by elephants and humans alike, is a different story from a desperate desert crossing, and it explains different patterns in the fossil record.
More specimens and tighter dating will test the corridor idea, and comparisons with other Levantine sites will show whether Gesher Benot Ya'aqov was typical or unusually rich. The tooth itself, scanned and published, joins the permanent record other teams can reanalyse as methods improve.
