Bruh. Homo sapien evolution is a thing. We've spent thousands of years from one another living in completely different climates and latitudes, adjusting to different fauna, bacteria, insects and environment to exploit which led to us looking extremely different from one another. A black guy is simply much different from a swedish, iranian, aborignal, chinese or peruvian. Not just in skin colour, but in bone density, skull shape, skeletal structure and tons of other differences caused by differences in genetics.

The whole out of Africa thing is currently again debatable, but nonetheless, what do you think, happened to early primitive homo sapiens, moving from the red area in my picture up the nile towards the earasian content, where all of the sudden these homonids encountered seasonal climates, less fruit hanging around and thought like: fuck, we need to survive here. Evolution through environment selected people that were most creative, high in problem solving, delayed gratifucation, future planning and cooperation. They also needed fuckton more of cortical space for all the new motor and communication skills to be installed and remembered (4 different seasons call for 4 different approaches with nature which means more communication and collaboration within tribes. Cold means you need to have fine hand motor skills in order to make clothes out of animals, only animals there were fucking large mammoths so they needed close collaboration and incredible chucking power for spears to kill them). Caucasian brain size is statistically higher than sub saharan black brain size. Average hip weight is statistically higher in caucasian woman than black woman. We're homo sapiens, all, but still completely different peoples. Look at the pygmee's, the sentalese. That's not just a social construct, but thats the difference between a species and thousands of years of evolution that can drastically alter the expression of general homo sapien intelligence.

Alright /sci/ i'm gonna blow your mind

rocks are denser than water, and gravity pulls things that are dense down

with me so far

now, the mind blower

look at this map. There's more rock up (aka north) than down (aka south), so why doesn't the earth just flip over OR the bits of rock float down due to the gravitational rotation of the earth?

You can't explain this, ergo the earth must be flat
