The above is a schematic chart showing what we humans regard as "progress." The move from left to right is roughly logorithmatic.  The chart is a grossly pictorial and schematic representation that illustrates the social evolutionary process. 

The red line beginning to your left represents the hunting-gathering world-view and way of life and the dotted extension its mainstream departure from the mainstream.  The blue line shows the branching off and rise of the "Hunting technological world- view system" and  what academia titled "the cro-magnon man." This marks the beginning of human groups becoming larger than the basic hunting-gathering groups we evolved to live in through millions of years of evolution. This also marks the acceleration of human social-evolutionary-developed- technological progress.

The Hunting WV belief system later declined due to over-kill, leading to the amplifying of the woman's gathering role and the beginning of an agricultural-based "fem-fertility belief system."  Later, with the last "burgeoning," patriarchal- monogamous systems evolved that enabled the formation of government and thus the organizing of the communal groups into civilizations.

NOTE THAT THE CHART STOPS AT THE PRESENT

Below is a symbolic representing of the chart showing two possible divergences from the present.

The narrow verticle line represents the present. The divergence represents the future.

 These are the choices we have . . . .

The black line represents the Kurgan barbarian world-view system and the barbarian belief systems that followed it.

There is no such thing as "barbarians," only barbarian world-view and way-of- thinking belief systems.
