Are Humans Still Evolving?

Science Now asks the question, “are humans still evolving?”  Comparisons of genes and chromosomes between different people groups from Asia, Europe and Africa are challenging the view that there is one human genome.  Some long stretches of DNA are inverted in some groups, and women so affected seem to have more children on average, even though the section isn’t related to fertility.  Oxford statistician Peter Donnelly says of these surprising findings, “This could be the tip of several icebergs.”

So “The Human Genome” may be a myth.  Perhaps DNA storage is more dynamic than we expected.  The story does not establish any connection to evolution by natural selection except by assuming evolution and its commonly-accepted time scale.  Notice this non-sequitur: at the end, Donnelly says, “If such inversions are common, then there isn’t just one version of the human genome… this shows natural selection is still acting on us.”  Come again?  We’re here, we have differences, therefore we evolved?  Get a grip, Pete.
