I think a bit of both, but it had nothing to do with "societal advancement." Most of the important ancient technologies already existed before this shift was made. The onset of patriarchy about 7k years ago actually disrupted "civilization" for a good long time.

"But by the fifth millennium B.C.E., or about seven thousand years ago, we begin to find evidence of what Mellaart calls a pattern of disruption of the old Neolithic cultures in the Near East.5 Archaeological remains indicate clear signs of stress by this time in many territories. There is evidence of invasions, natural catastrophes, and sometimes both, causing large-scale destruction and dislocation. In many areas the old painted pottery traditions disappear. Bit by devastating bit, a period of cultural regression and stagnation sets in.

“Thanks to the growing number of radiocarbon dates, it is now possible to trace several migratory waves of steppe pastoralists or ‘Kurgan’ people that swept across prehistoric Europe,” reports Gimbutas. These repeated incursions and ensuing culture shocks and population shifts were concentrated in three major thrusts: Wave No. 1, at c. 4300–4200 B.C.E.; Wave No. 2, c. 3400–3200 B.C.E.; and Wave No. 3, c. 3000–2800 B.C.E. (dates are calibrated to dendrochronology).7

The Kurgans were of what scholars call Indo-European or Aryan language-speaking stock, a type that was in modern times to be idealized by Nietzsche and then Hitler as the only pure European race. In fact, they were not the original Europeans, as they swarmed down on that continent from the Asiatic and European northeast. Nor were they even originally Indian, for there was another people, the Dravidians, who lived in India before the Aryan invaders conquered them.8 But the term Indo-European has stuck. It characterizes a long line of invasions from the Asiatic and European north by nomadic peoples. Ruled by powerful priests and warriors, they brought with them their male gods of war and mountains.(emphasis mine) And as Aryans in India, Hittites and Mittani in the Fertile Crescent, Luwians in Anatolia, Kurgans in eastern Europe, Achaeans and later Dorians in Greece, they gradually imposed their ideologies and ways of life on the lands and peoples they conquered.9"

The Kurgan invasions shifted much of the world from egalitarian enclaves that lived in relative peace, and worshipped a life-giving goddess as the supreme deity to a war-oriented, male dominated hierarchical culture where might makes right. Patriarchal dominance hierarchies spread quickly because they were so disruptive. Eventually they allowed the pyramids to be built, etc., but only on the backs of slaves.

Thanks for the link. I do think that power is seductive and patriarchy is so entrenched that it will be difficult to unseat it entirely. I'd just like to see us move even a little bit toward greater egalitarianism.
