If You Have Gap Teeth — DNA Finally Revealed Where They Really Come From

In the mid 1960s, a young model walked into New York’s top agencies and was told to fix the small space between her front teeth, or never come back. Lauren Hutton refused, and that gap went on to grace dozens of Vogue covers. But here’s what no one told you: that space isn’t a flaw, a bad habit, or an accident. Geneticists have traced it to named genes, a jaw that has been shrinking for 12,000 years, and a story that began long before you were born. And that’s just one thread in a much bigger story about what DNA reveals about your face, your family, and your deep ancestry. In this video, we break down: ✅ Why nearly every child has a gap, and why some keep it for life ✅ How scientists proved the gap is inherited, with heritability around 0.32 ✅ The “arithmetic of the mouth”: jaw size vs. tooth size, inherited separately ✅ The genes behind it: MSX1, PAX9, AXIN2, WNT10A ✅ The frenum factor, and why the gap is multifactorial ✅ How farming shrank the human jaw and created an evolutionary mismatch ✅ Why the Yoruba prize the gap, the French call it “the teeth of happiness,” and Chaucer gave it to the Wife of Bath Your gap was never something that happened to you; it’s an inheritance you carry. 🔔 Subscribe to The Gene Archive for more DNA stories that reveal where we really come from 👍 Like this video if you or someone in your family has a gap 💬 Comment below: who in your family shares your smile? #GapTeeth #Diastema #DNA #Genetics #AncestryDNA #HumanEvolution #TheGeneArchive
