I have written a book on this intriguing subject which has just been published.
In this blog I will post excerpts and other interesting texts on this fascinating subject.

Levallois tools: did this technology originate in Asia?

Earlier this year, a paper (Kumar Akhilesh et al., Early Middle Palaeolithic culture in India around 385–172 ka reframes Out of Africa models, Nature volume 554, pages 97-101, 01 February 2018) reported finding Levallois stone tools in a site called Attirampakam, in India. These tools were about 385,000 years old, which put the date of this stone knapping technology further back in time than had been previously expected.

These Indian tools are even older than the Levallois tools found in Africa, and they predate the currently accepted date of Homo sapiens expansion out of Africa.

Modern Brains

The Levallois tools represent a shift in stone knapping know-how. Until then the Acheulian (developed by Homo erectus) technique had been in use for over 1.4 million years.

It was named after the site where they were first discovered in the 1800s: Levallois-Perret, a suburb of Paris, in France.

It is distinctive of a more brainier hominid, who developed a new technique for knapping stones to obtain sharp flint tools.

But who made them? until recently it had been suggested that they were the result of archaic Homo sapiens migrating out of Africa.

But with the Indian tools dated around 385 kya and some found in Armenia (D.S. Adler et al., Early Levallois technology and the Lower to Middle Paleolithic transition in the Southern Caucasus, Science 26 Sep 2014: Vol. 345, Issue 6204, pp. 1609-1613 DOI: 10.1126/science.1256484) aged 325 kya, this explanation seems unfounded: there were no H. sapiens at that time.

Adler writes: "Our data from Nor Geghi, Armenia... are consistent with the hypothesis that this transition occurred independently within geographically dispersed, technologically precocious hominin populations with a shared technological ancestry."

Suggesting a pre-Homo sapiens origin.

The oldest remains of Homo sapiens and Levallois tools are from a site in Morocco and they are much more recent than the Armenian and Indian tools: 315,000 years old. (Read more).

We know that the Neanderthal made them in Europe, could they be the authors of these Eurasian tools?

A paper published four days ago: Yue Hu et al.Late Middle Pleistocene Levallois stone-tool technology in southwest China, DO 10.1038/s41586-018-0710-1 ID Nature 19. Nov. 2018), reports finding Levallois tools in China:

"Here we present evidence of Levallois technology from the lithic assemblage of the Guanyindong Cave site in southwest China, dated to approximately 170,000-80,000 years ago. To our knowledge, this is the earliest evidence of Levallois technology in east Asia. Our findings thus challenge the existing model of the origin and spread of Levallois technologies in east Asia and its links toa Late Pleistocene dispersal of modern humans."

So once again who made them? This date is prior to any known H. sapiens presence in China. Were they Neanderthals? or perhaps Denisovans, who lived in Southern and Central Asia at that time?

Here we have a technological break-through that seems to have originated Out of Africa and not In Africa, our purported craddle of mankind. Did modern humans evolve outside of Africa?
