Early humans are thought to have wandered around without any clothing and spoke in languages that lacked any syntax, orating one-liners to get information across. Obviously, humans didn't suddenly develop modern levels of intelligence.

This Wikipedia article basically goes over how advances in human intelligence were consequences of hardships faced by humans, giving plenty of credence to the idea that Eurasians are more intelligent than black Africans due to the fact that life was simply more difficult in Eurasia. (North Africans are the descendants of Eurasians.)

I still can't think of a clever paragraph or two to spam whenever I see someone online saying racial differences in intelligence don't exist that makes it look ridiculous to even question the non-existence of racial differences in intelligence. Ryan Faulk has produced some great videos, but those are long videos and filled with to the brim autism. Also, plenty of normies aren't going to want to watch his videos when the name Alt Hype sounds very similar to alt right, and a lot of the symbols he uses are from politically fringe elements, thus making him look like a nut from the eyes of people who are familiar with those symbols.
