For serious discussion of the controversies, approaches and enigmas surrounding the origins and development of the human species and of human civilization. (NB: for more ‘out there’ posts we point you in the direction of the ‘Paranormal & Supernatural

"The idea that civilization advanced in a linear fashion is somewhat of a misnomer as before such long lasting continuous cultures like Dynastic Egypt, Babylon, and China came about, I think most, including concurrently with these cultures, would be best characterized as successive. For example, Akkad was already their own thing, a tribal confederate, before they took over Sumer and it was only after that they became unified, the "Akkadian Empire", which after the fact having absorbed Sumerian culture continued on their merry way as something "new". Same thing with Assyria and Babylon after Akkad fell. There were already people there which they absorbed Akkadian culture, augmented by migrants and expats, and became something more than they were before. I think what is linear is the medium of civilization not necessarily the people who later came to benefit from it."
I suggest that time should be considered just one of the axis of the investigations into human history. The other axis, the far greater, is represented by 'space'. Space is all the discoveries about the development of the material culture and expansion of people and what they did.
People do have a tendency to build moral criteria into the axis of time, societies improved, the cultures were better, smarter, more scientific, evolved.
Don't forget the axis of space!
