DFM, Not all when you consider that so many early archeologists were European and American with bias against any group not related to their own ancestors.

Just recently new discoveries in Asia show development of tools making in Asia, matched the time periods of Europe and the Middle East while western Archaeologists assumed for a long time that Europe and Middle Eastern tool making predated Asian too making. The western bias has been noted for decades. Same as the Western bias against tribal societies being less complex socially, and politically than civilized societies.

I noted such bias even in high school.
