Evolution vs. Creationism

It is amazing to me that some church bodies still continue to argue about evolution and creationism. As much as I try to tune out all of the noise made about this, at times the volume is too high to ignore. Even the Roman Catholic church has not been immune to the controversy. The following are some comments by Jesuit Father Edward Oakes, a theology professor at the University of St. Mary of the Lake. (The emphasis in bold is mine.)
The Church has no "doctrine" on evolution, any more than it has a doctrine on tectonic plates or a magisterial teaching on how human consciousness arises from the electrical firings inside the neurology of the brain. These matters are both beyond the competence of the magisterium and are irrelevant to salvation, anyway. . . .
If "creationism" means six-day creation as a few Christian fundamentalists still hold, then there is no chance in the world that the Catholic Church will join that cause. But "creationism" can also refer to the total ontological dependence of the universe on God's creative act of will, and nothing in the theory of evolution can threaten that essential doctrine of the Catholic faith.
. . .

If evolution simply means "descent with modification," then I would agree that evolution must be regarded as confirmed by scientific "fact" -- meaning by that tendentious word a reality that no one can afford to deny, except at the price of obscurantism.

Defined in that way, the theory of evolution claims that all life began about 3.5 billion years ago as a single-celled, self-replicating organism from which we are all descended. Since everyone now reading this sentence once began his or her existence as a single-celled organism, I hardly see how such a theory can be regarded as inherently implausible. Plus, let's not forget that the biological basis of the Church's opposition to abortion is based on the single-celled origin of human life.

And once one traces the transmission of life all the way back, using the science of genetics as one's marker, and once one follows the paths of life back to life's remotest beginnings, one sees how the various life-forms are interrelated. Moreover, using genetics, one can roughly spot when each branch of life broke off from its parent-branches.

The problem comes from the conflation of Darwinism with evolution strictly defined. Now Darwinism asserts not just the fact of "descent with modification"; it also claims to know the "how" of evolution: Evolution occurred, it claims, by means of something it calls "natural selection."

Again, if that term is strictly defined, it simply means that only those organisms that reach reproductive age get to transmit their genes; and if those genes were somehow "responsible" for helping that organism reach reproductive age, then that "helpfulness" will likely contribute to later success as well.

As with the doctrine that all life began as a single-celled organism, I hardly see how such an obvious insight can be regarded as controversial. But then again, we have to ask: How much does the concept of natural selection actually explain the "how" of evolution? Certainly, this question is a very controversial point among philosophers of biology.
