Before he became Pope Benedict he hsa stated on the subject-
"Since it has been demonstrated that all living organisms on earth are
genetically related, it is virtually certain that all living organisms have
descended from this first organism. Converging evidence from many studies in the
physical and biological sciences furnishes mounting support for some theory of
evolution to account for the development and diversification of life on earth,
while controversy continues over the pace and mechanisms of evolution."
