How Did Humans Invent Racism?

#ancienthumans #ancienthistory Skin color is just sunlight chemistry. So how did it become the foundation of entire legal systems, empires and wars? This video traces how humans invented racism, from a tribal-brain glitch to a ledger of profit, and why the idea has a birthday, authors and a paper trail. In this video, we follow the evidence step by step: What skin color actually is: melanin, 150+ genes, UV light, folate and vitamin D The "us versus them" instinct and Henri Tajfel's minimal-group experiment What ancient Egypt, Greece and Aristotle really said about difference How the Atlantic slave trade, papal bulls and the Toledo blood purity law moved prejudice from belief to bloodline How Bernier, Linnaeus, Blumenbach and Samuel Morton turned a justification into "science" Bacon's Rebellion and the Virginia laws that built racial categories into law How Boas, Lewontin, modern genomics and ancient DNA (Cheddar Man) took the idea apart Was racism inevitable? The tribal reflex almost certainly was. The specific idea of biological race was not. Enjoyed this deep dive?
