Left-Genetics Theory Debunked: Biology Professors teaching outdated, obsolete bunk to their students

Richard Lewontin, a Harvard Genetics Professor, was the purveyor of F-st Fixation Index.  The theory sets forth that there is more variation within human populations than between populations.  Essentially, Lewontin supporters believe that human variation between ethnic groups is negligible, and in many ways not even worth consideration.  

Lewontin was a self-proclaimed Marxist.  Even liberal media writing in his obituary concede that his political beliefs were a blotch on his record.  But his theories have had great influence in modern genetics teachings.  Every first year Biology student learns of Lewontin's F-st.  

But emerging facts go against the Lewontin narrative.  Most especially, the emerging fossil record for hominin species, is proving that enormous variation has existed in Genus Homo and continues today.  As of Nobel Prize winning Svante Paabo's magnificent discovery of Neanderthal DNA in the Eurasian genome in 2010, we know for certain now, that modern Humans are essentially hybrid species.  Lewontin had no idea in the 1970s that Neanderthal,  Denisovan or Australopithecine DNA would one day be found in modern Humans.  Thus, his F-st hypothesis has been rendered obsolete.
