>Not sure if your thing about engines is even true, feel free to prove it. Google is your friend. >Just because an ecosystem is complex doesn't mean it's not built from simple rules. It also doesn't mean those simple rules will create simple or expected results. Moving a vortex shedding from a wing tip .5mm inboard can mean the difference from an aero device on the other side of the vehicle working properly or not. >The norm in nature is a high birth rate and death rate, almost all species have higher rates of birth and death than modern humans, and the higher the rate of birth and death, the faster selection works. That's not true though. The fruit fly lives two weeks and hasn't physically evolved in 5 million years give or take. >There's about 30,000 years of natural evolution between Eurasians, Africans, and Native Americans, at least 10,000 years between different major Eurasian groups, and a few thousand years between different European nationalities, plenty of time to explain the amount of differentiation between different racial and ethnic groups within humanity. You mean forced race mixing due to war?
