I'm trying to understand the scale and scope of time involved in human history, if by human we mean modern humans as biology would classify us. From what little I know, it kind of seems as if the era since we began recording human history coincides with, well, lots of rapid change, pretty much constantly.
But our species history prior to the development of writing systems and methods of recording history--was it all quite slow and relatively uneventful by comparison, or does it only seem that way because we haven't got people's written, documented accounts of their lives?
"Uneventful" seems like a fairly harsh way of describing the spread of anatomically modern humans from Africa to the rest of the world, their interaction and interbreeding with archaic hominids, survival of population bottlenecks, natural disasters, mass extinctions, and climate changes, then development of agriculture and complex settled and urban societies. All of this predates recorded history and can only be pieced together from archaeological records and genetic and linguistic evidence.
You are probably correct about technology changing slowly. This is in part because of low population density, which is often correlated with lower technological complexity.
However, on a day to day basis there would have been plenty of "interesting" events happening. Excavations of prehistoric cemeteries in Egypt and Europe have unearthed evidence of widespread interpersonal violence that seems to suggest frequent massacres if not endemic warfare.
