Sometimes I find that including more references and information creates more confusion.
For the period I am calling mid Pleistocene prehistory, in Africa I am finding references to anatomically modern man. The middle East has a few unspecified references to tools, and to some Neanderthals. South Asia has a references to Soanian culture, which is identified more with stones than bones. The Orient and Southeast Asian and Oceanic peoples have references to Homo erectus in the early period. Europe chiefly has references to Neanderthals. Eventually, I will have to broaden the connections to include more nations, subdivide the period, and find better references to clarify developments of this period. In the meantime, stone age developments and hunting and gathering peoples are chiefly applicable. There are traces of the origins of social institutions, but I consider them more speculative than substantial, and I lack good references. Pretty much the same goes for culture.
