If you are of European or middle eastern ancestry you have some high quality, get the job done, hard headed Neanderthal genetics. Be thankful.
German & Austrian descent here with some Irish sprinkled in. One of the last known genetic defects of the Neanderthal race is identified as HLA-B27, an indicator for Ankylosing Spondylitis, which is a spontaneous fusing of the spine and joints, along with characteristics of a protruding chin and oversided knuckles. HLA-B27 explains much of why Neanderthals were portrayed with protruding chins and hunched backs. Ankylosing Spondylitis causes spontaneous fusion followed by curvature of the spine.
As luck would have it, I have that gene. Researched it to the hilt, it was spread by the Noords who, upon invading much of Europe "spread their seed" including primarily what are now known as German's Austrian's French and the like. Speculation was the Noords also routinely inter-bred with the Neanderthals, who, generations later bred with the Germans, Austrians, Irish, French, etc..
So when my wife calls me a knuckle dragging neanderthal, I simply grunt and say "yep."
Exactly.... the most sucessful civilizations have evolved from those of mixed genetic heritage.
