When we read about Creation in Genesis, we run the risk of imagining God was a magician, with a magic wand able to do everything. But that is not so.... He created human beings and let them develop according to the internal laws that he gave to each one so they would reach their fulfilment.That is strictly the Aristotelian position. The giveaway is when he speaks of human beings having 'internal laws' that govern how they 'reach their fulfilment.' The question is how things come to be, and Aristotle gives his answer in Physics II.
Of things that exist, some exist by nature, some from other causes.... [those that exist by nature] present a feature in which they differ from things which are not constituted by nature. Each of them has within itself a principle of motion and of stationariness (in respect of place, or of growth and decrease, or by way of alteration). On the other hand, a bed and a coat and anything else of that sort, qua receiving these designations i.e. in so far as they are products of art-have no innate impulse to change.So there is a distinction being made between things that exist 'by nature' and those that are products of (human) art. Things that exist by nature have 'within themselves a principle' -- the Pope said an 'internal law' -- that governs how they come to be, how they grow or decline, and how they can change. That's why a bear and a man and a horse are different: they are governed by different natures. The bear and the man can eat more or less the same things, but their bodies will do different things with the food they intake. The bear will grow larger, stronger, faster; the man will develop reason and a form fit for manipulation of his environment to a greater degree. The horse can't eat many of the things that a man or a bear can eat, but on grass alone will grow bigger and stronger than either.
The Medieval Aristotelian position -- not only in the Church, but predating the Church's adoption in Jewish and Islamic Aristotelian philosophers such as Maimonides and Avicenna -- was that God's activity produced the world and its laws. The laws were themselves the mechanisms by which creation was effected. Maimonides goes so far as to give an account of Moses' parting of the Red Sea as a kind of understanding of the laws at work: it happened to be the one night when the wind was going to blow in just the right way, for just the right time, to craft the parted sea. Moses was a prophet, but that meant that he had come through his intellect to understand something about the laws at work.
There are a lot of philosophical and theological issues on this ground that might be hotly debated. But the point, here, is that the position the media is taking to be radical is approximately a thousand years old: and it's based on a position far older still.
