The Neanderthal Connection: Genetic Influence on Pain Sensitivity

Scientists have discovered that certain Neanderthal genes, specifically three variations of the SCN9A gene, are associated with increased sensitivity to pain caused by sharp prodding. These gene variants were found at a high frequency among individuals with Native American ancestry. The study, which analyzed genetic data from over 5,900 individuals across Latin America, suggests that these genes may have been passed down through interbreeding between Neanderthals and modern humans. The researchers also speculate that these genes may have provided an evolutionary advantage in coping with cold conditions. Further research is needed to fully understand the effects of these gene variants.

The Influence of Neanderthal DNA on Pain Sensitivity Revealed

Neanderthal gene variants in the SCN9A gene, which codes for a protein involved in pain detection, may increase pain sensitivity in individuals who carry them. A study analyzing genetic samples from over 5,900 people in Latin American countries found that these Neanderthal gene variants were more common in individuals with Native American ancestry. The variants were associated with increased sensitivity to pain caused by sharp objects but not heat or pressure. The study suggests that these gene variants may have been inherited from Neanderthals who interbred with modern humans migrating into the Americas. The findings provide insights into the genetic basis of pain sensitivity and its potential evolutionary significance.
