If the origin of human beings can be explained by a biological evolution, does that mean that we are no more that robots following a predetermined course? How can human beings be free and responsible? How can we still talk in terms of the action of a Creator where everything seems to be determined by biological and chemical mechanisms? Here a group of scientists who are also Christians presents the result of several years reflections on the origins of life, the increasing autonomy of living beings, the emergence of humanity and human freedom, our relationship with the Creator, and the drama of evil and death. To shed some light on these mysteries, they show how evolution can be read as a demonstrations of the creative activity of God.
