If You're Left-Handed — DNA Finally Revealed Why Only 10% of Humans Are

Why are only 10% of humans left-handed — and why has that number never changed in thousands of years? From Prince Albert (King George VI) being forced to write right-handed as a child, to the 2019 Oxford study that finally cracked the genetic code behind handedness, this video dives into the real science of why some of us reach for the world with our left hand. We break down the landmark UK Biobank research (1.77 million people!), the 41 genetic loci linked to left-handedness, why identical twins don't always share a dominant hand, and the wild "fighting hypothesis" that links left-handedness to violence and combat advantage in ancient societies. You'll also learn how brain wiring — not muscles — is at the center of it all, and why left-handedness may start being decided before you're even born. If you've ever been told left-handedness is "unlucky," "sinister," or something to fix — this video explains what the DNA actually says. 🧬 Genetics | 🧠 Neuroscience | 📜 History #LeftHanded #Genetics #DNA #Neuroscience #ScienceExplained #Epigenetics #BrainScience #HumanEvolution #GeneticsFacts #HandednessScience #KingGeorgeVI #ScienceDocumentary #Biology #MindBlowing #DidYouKnow
