If You're Left-Handed — DNA Finally Revealed Why Only 10% of Humans Are
Why are only about 10% of people left-handed? For centuries, scientists believed the answer was hidden in a single gene—but modern DNA research revealed a far more fascinating story. In this documentary, we explore the latest discoveries in genetics, brain development, epigenetics, and human evolution to uncover why left-handedness has remained remarkably consistent throughout history. From ancient Roman gladiators to modern neuroscience, the evidence reveals that being left-handed is not a defect—it's an extraordinary part of human evolution. You'll discover how dozens of genetic regions, early fetal development, and evolutionary advantages helped preserve left-handedness across thousands of generations, changing everything scientists thought they knew about the human brain. #lefthanded #dna #genetics #humanevolution #science #ancientdna #neuroscience #documentary #anthropology #history
