I was intrigued by your article for a couple of reasons. Isn’t this what Steven J. Gould said, that evolution is punctuated by environmental stresses that can bring about adapt-or-die changes rapidly? Also, what are the implications for the geneticists who base their mitochondrial DNA dating techniques on what they consider a fairly constant rate […]
