Genetic Similarities Between Fins and Limbs -- Evidence for Evolution, Maybe, but Not for Darwinism

In a recent New York Times article, Carl Zimmer described new research from Neil Shubin's lab at the University of Chicago on the developmental genetics of fish fins. He rightly points out that the work reveals (or more properly confirms, as previous evo-devo work points in very much the same direction) that very deep similarities exist between the development of fins and limbs. This is not surprising. It has been acknowledged since the time of Richard Owen, 160 years ago, that the lateral a...
