A few words from Pope Benedict:

Pope Benedict XVI
"Monod nonetheless finds the possibility for evolution in the fact that in the very propagation of the project there can be mistakes in the act of transmission. Because nature is conservative, these mistakes, once having come into existence, are carried on. Such mistakes can add up, and from the adding up of mistakes something new can arise. Now an astonishing conclusion follows: It was in this way that the whole world of living creatures, and human beings themselves, came into existence. We are the product of “haphazard mistakes.”
“What response shall we make to this view? It is the affair of the natural sciences to explain how the tree of life in particular continues to grow and how new branches shoot out from it. This is not a matter for faith. But we must have the audacity to say that the great projects of the living creation are not the products of chance and error. Nor are they the products of a selective process to which divine predicates can be attributed in illogical, unscientific, and even mythic fashion. The great projects of the living creation point to a creating Reason and show us a creating Intelligence, and they do so more luminously and radiantly today than ever before. Thus we can say today with a new certitude and joyousness that the human being is indeed a divine project, which only the creating Intelligence was strong and great and audacious enough to conceive of. Human beings are not a mistake but something willed; they are the fruit of love. They can disclose in themselves, in the bold project that they are, the language of the creating Intelligence that speaks to them and that moves them to say: Yes, Father, you have willed me.”
Peace,
