Leonid Moroz, professor of neuroscience, chemistry, and biology at the University of Florida College of Medicine, in a recent article published in The Scientist entitled “The Devolution of Evolution,” comments on Theodosius Dobzhansky assertion nearly 40 years ago that “Nothing in biology makes sense except in the light of evolution.”

If Dobzhansky’s assertion is true, “How is it, then”, Moroz asks, “that so few newly minted PhDs in the biological sciences have taken any formal graduate school courses in evolution or biodiversity?” Continue Reading
