"From the perspective of Christian theology, biological evolution and creation are by no means mutually exclusive .... None of the evolutionary mechanisms opposes the affirmation that God wanted—in other words, created—man. Neither is this opposed by the casual nature of the many events that happened during the slow development of life, as long as the recourse to chance remains a simple scientific reading of phenomena," Father Giuseppe Tanzella-Nitti, a professor of fundamental theology at the Pontifical University of the Holy Cross in Rome, said during a Vatican press conference yesterday. "I hope that the natural sciences may be used by theology as a positive informational resource, and not just seen as a source of problems."
