Now I won’t dispute the inferiority of congoloids and melanoids. But Africa has the worst Geography besides Antarctica lol. There are no native solutions. Study geography. Like formally. Africa is perfectly centered over the equator. Within the equator belt is also where tons of tropical disease spreads. What is the best habitat for breeding mosquitos? Farm land lol. Slash and burn like South America which loses more farmland every year than one can wrap their head around? Right outside the equator belt, which will rain about half the time also makes productivity challenging and keeps farmland prime breeding grounds for mosquitos, are the doldrums, aka the horse latitudes aka the desert belts. Caused by high pressure which makes cloud formation impossible. Jack shit for wind. No water vapir being carried up high in the sky but instead the atmosphere just pushes down and holds the massive heat built up all day. Nothing anyone can do about that. I’ll skip a ton of other large scale inherent handicaps Africa offers human development and end with these last two. Africa doesnt have native species suitable for agriculture. All the livestock animals of Africa were brought there and diffused within the continent after being introduced. And a North-South Axis is terrible for diffusion. Crops diffuse along latitude lines with uniform photoperiod. Most land trade and historical movement of people, crops, tech etc on the Earth were along lattitude libes. Getting crops and tech to move North-South across 2 giant desserts and rain forest over like 5k miles at least from the Mediterranean to South Africa for premodern people would be rough no matter your race. Africa is the only fucking continent hit twice by those dessert belts created by the Earth’s wind belt systems. Ever notice ~ 30’N/S anywhere on Earth relative to geomorphology and Earth’s tilt? Have you ever been to Africa? It really is a very inhospitable shithole with no real resource base for developing without outside inputs. The white man’s progression was adaptation to white man land. Africa didn’t have a wheel until there were domesticated animals to pull them came at the same time. Africans are dumb bc of their geography. Evolving there would fucking stunt you and make you have to be all muhdik just to survive. Bro you couldn’t do shit even with modern equipment anyways so shit the fuck up lol.
