Is the church evolving? Relax, it's OK?

So how might scientists view the discussions in our church these days? Here's at least one take on things:

Christianity has already evolved into multiple divisions and subdivisions in its 2,000-year history. If the current crisis does indeed "permanently split the family of churches descended from the Church of England," we may be witnessing a modern instance of cultural speciation.

Citing current controversies in the Anglican Communion, the article, in Science & Theology News, says this:

When Charles Darwin had the fundamental insight that would become the theory of natural selection, he gleaned a principle not limited to biology. Rather, he put his finger on what happens to any system that makes copies of itself. Given the pressures of the environment and the imperfect transmission of traits, some alterations will inevitably prove more successful than others. Differing versions of the original will branch off. In time, entirely new systems may emerge.

All of this applies as much to non-biological phenomena as to microbes and men. Indeed, one instance of just such a "descent with modification" might be found in changing religious tradition.
