To be fair it does sound a lot like evolution with civilisations as the unit of reproduction. Not getting wiped out by the war-like tribe next door is pretty much the only metric for survival. All the other stuff like self induced climate change is for long term civilisations
Although I do tend to look on these civilisations as being run by the bully at school who was beaten up by his dad and had no real idea why he was angry so much. If he was big clever and angry he could take over a tribe pretty quick and self select.
