INTRODUCTION At both ends of the new Jordan Science Hall on the Notre Dame campus, engraved in large medallions in the floor, is an often repeated statement of geneticist Theodosius Dobzhansky (1900-75), published 2 y before his death: "Nothing makes sense in biology except in the light of evolution" (Dobzhansky 1973). This statement on the floor of a hall with statues of two Holy Cross priests--physicist-philosopher Rev. John Zahm (1851-1921), and fellow priest-scientist, Belgian-born botanist and chemist Fr. Julius Nieuwland (1878-1936)--above its main entrance would certainly have pleased Fr. Zahm, the individual most responsible for the development of the scientific research side of the University of Notre Dame. This would be especially true since this familiar statement from Dobzhansky was the title of an article in which the great geneticist and evolutionist argued for the compatibility of evolution and a sophisticated understanding of "creation" that ended with praise of another priest-scientist and enthusiast for evolution, the French Jesuit Pierre Teilhard de Chardin (1881-1955).
