Lengthy held in a non-public assortment, the newly analysed tooth of an roughly 9-year-old Neanderthal little one marks the hominin’s southernmost identified vary. Evaluation of the related archaeological assemblage suggests Neanderthals used Nubian Levallois know-how, beforehand regarded as restricted to Homo sapiens.

With a excessive focus of cave websites harbouring proof of previous populations and their behaviour, the Levant is a significant centre for human origins analysis. For over a century, archaeological excavations within the Levant have produced human fossils and stone software assemblages that reveal landscapes inhabited by each Neanderthals and Homo sapiens, making this area a possible mixing floor between populations. Distinguishing these populations by stone software assemblages alone is tough, however one know-how, the distinct Nubian Levallois methodology, is argued to have been produced solely by Homo sapiens.

In a brand new examine revealed in Scientific Studies, researchers from the Max Planck Institute for the Science of Human Historical past teamed up with worldwide companions to re-examine the fossil and archaeological file of Shukbah Cave. Their findings lengthen the southernmost identified vary of Neanderthals and recommend that our now-extinct family made use of a know-how beforehand argued to be a trademark of contemporary people. This examine marks the primary time the lone human tooth from the positioning has been studied intimately, together with a significant comparative examine analyzing the stone software assemblage.

“Websites the place hominin fossils are immediately related to stone software assemblages stay a rarity — however the examine of each fossils and instruments is essential for understanding hominin occupations of Shukbah Cave and the bigger area,” says lead creator Dr Jimbob Blinkhorn, previously of Royal Holloway, College of London and now with the Pan-African Evolution Analysis Group (Max Planck Institute for the Science of Human Historical past).

Shukbah Cave was first excavated within the spring of 1928 by Dorothy Garrod, who reported a wealthy assemblage of animal bones and Mousterian-style stone instruments cemented in breccia deposits, typically concentrated in well-marked hearths. She additionally recognized a big, distinctive human molar. Nonetheless, the specimen was saved in a non-public assortment for many of the 20th century, prohibiting comparative research utilizing fashionable strategies. The current re-identification of the tooth on the Pure Historical past Museum in London has led to new detailed work on the Shukbah collections.

“Professor Garrod instantly noticed how distinctive this tooth was. We have examined the dimensions, form and each the exterior and inner 3D construction of the tooth, and in contrast that to Holocene and Pleistocene Homo sapiens and Neanderthal specimens. This has enabled us to obviously characterise the tooth as belonging to an roughly 9 12 months outdated Neanderthal little one,” says Dr. Clément Zanolli, from Université de Bordeaux. “Shukbah marks the southernmost extent of the Neanderthal vary identified to this point,” provides Zanolli.

Though Homo sapiens and Neanderthals shared using a large suite of stone software applied sciences, Nubian Levallois know-how has not too long ago been argued to have been solely utilized by Homo sapiens. The argument has been made specifically in southwest Asia, the place Nubian Levallois instruments have been used to trace human dispersals within the absence of fossils.

“Illustrations of the stone software collections from Shukbah hinted on the presence of Nubian Levallois know-how so we revisited the collections to analyze additional. Ultimately, we recognized many extra artefacts produced utilizing the Nubian Levallois strategies than we had anticipated,” says Blinkhorn. “That is the primary time they have been present in direct affiliation with Neanderthal fossils, which suggests we will not make a easy hyperlink between this know-how and Homo sapiens.”

“Southwest Asia is a dynamic area when it comes to hominin demography, behaviour and environmental change, and could also be significantly necessary to look at interactions between Neanderthals and Homo sapiens,” provides Prof Simon Blockley, of Royal Holloway, College of London. “This examine highlights the geographic vary of Neanderthal populations and their behavioural flexibility, but in addition points a well timed notice of warning that there are not any easy hyperlinks between explicit hominins and particular stone software applied sciences.”

“So far we’ve no direct proof of a Neanderthal presence in Africa,” stated Prof Chris Stringer of the Pure Historical past Museum. “However the southerly location of Shukbah, solely about 400 km from Cairo, ought to remind us that they could have even dispersed into Africa at instances.”


Researchers concerned on this examine embrace students from the Max Planck Institute for the Science of Human Historical past, Royal Holloway, College of London, the Université de Bordeaux, the Max Planck Institute for Chemical Ecology, the College of Malta, and the Pure Historical past Museum, London. This work was supported by the Leverhulme belief (RPH-2017-087).
