Daniel Adler suggests that the coexistence of bifacial and Levallois tools at the site provides the first clear evidence that local populations developed Levallois technology out of existing bifacial technology, and that the artifacts found at Nor Geghi reflect the technological flexibility and variability of a single population. He further concludes that this challenges the view that technological change resulted from population change, and suggests instead that Levallois technology developed independently from existing technology within different human populations who shared a common technological ancestry.<ref>Prehistoric Stone Tools Evolved Independently Within Local Populations, Say Researchers".
