A while ago, I happened upon an extremely interesting news story on malaysiandigest.com, “Are You A Hairy Diabetic Smoker Who Suffers Stomach Cramps? Blame Your Neanderthal Ancestor“, in which they describe the links between remnants of Neanderthal DNA and several modern health problems.
Do you have Type 2 diabetes, lupus, Crohn’s disease and biliary cirrhosis? These are some of the illnesses and conditions linked to Neanderthal DNA.
The Neanderthal DNA has also been linked to inherited traits such as tough skin, nails, and thick hair.
People of sub-Saharan Africa who did not migrate out and breed with Neanderthals, have very little or no Neanderthal DNA.
As genealogists, we do understood that traditional genealogy research techniques and tools can only take us back as far as a couple of centuries with any certainty.
DNA testing, however, opens up a whole new wealth of information about our ancestries that can be valuable in genealogy, but especially in determining, predicting and managing certain health conditions and traits.
The malaysiandigest.com article explains the connections in greater detail.
