We all have Neanderthal genes in us, apparently some more than others.
In a significant advance, the researchers mapped most of the Neanderthal genome—the first time that the heredity of such an ancient human species has been reliably reconstructed. The researchers, able for the first time to compare the relatively complete genetic coding of modern and prehistoric human species, found the Neanderthal legacy accounts for up to 4% of the human genome among people in much of the world today.
So sometime in our past, Neanderthals and Homo Sapiens interbred. Which probably explains the line of DNA resulting in Rush Limbaugh, Bill O’Reilly, Glenn Beck and quite a few Republicans.
