A recent study revealed that interbreeding with Neanderthals has caused lasting genetic effects, resulting in notable differences in tooth size and shape among ethnicities, particularly Europeans.
The research involved analyzing dental crown measurements from 882 Colombian volunteers, uncovering 18 genome regions influencing dental characteristics, with a distinct genetic variant linked to Europeans.
Lead author Dr. Kaustubh Adhikari clarified that while a specific gene leads to thinner incisors in some Europeans, it does not correlate with increased dental sensitivity or damage.
The study demonstrated that the variation in incisor thickness among carriers of this gene is modest and does not imply any dental health issues or risks.
