Lower Paleolithic Winds of Change: Prepared Core Technologies and the Onset of the Levallois Method in the Levantine Late Acheulian

The life cycle of a successful technological innovation usually follows well-known path: slow inception, gradual assimilation the technology, an increase in its frequency up to certain peak, and then decline. These different phases are characterized not only by varying use but also degree standardization distinguishability. Levallois method, sophisticated Middle Paleolithic technology aimed at producing desired stone items predetermined morphology, is one such innovation. It has been repeatedly suggested that method originated within earlier Lower Acheulian industries, this work contributes discussion. We analyze reduction trajectory prepared cores blanks from late sites Jaljulia Revadim, adding important new evidence for origins adoption human stone-tool repertoire period Levant. Revadim provide rare opportunity study patterns early innovations. yielded rich lithic assemblages typical include handaxes mostly dominated flake production technologies flake-tools. appearance both signals, our view, inception concepts related termed here proto-Levallois, Through detailed analysis their products, we able characterize stages using it as case broader discussion innovations during times.
