I've mentioned a couple of times how Western culture was permeated with the concept of evolution long before Darwin, and this undoubtedly had some effect on how Darwin's claims were received (this isn't meant to call evolution into question). Both times the primary example I gave was Wagner's Ring Cycle, his tetralogy of four massive operas, comprising over sixteen hours of music, which were well underway by the time Darwin published Origin of Species.
The first opera of the Ring Cycle is Das Rheingold, and the Vorspiel (prelude) with which it begins illustrates this idea beautifully. It starts with the basses playing a low E-flat which is held throughout the whole piece. Then the bassoons come in a fifth above them in B-flat. Then the brass instruments start. Slowly it builds, more instruments, more notes being added. Eventually, emanating from that low E-flat, you have an indescribably beautiful harmony, harmony in the fullest sense: many different voices, coming together without clashing with each other, and creating a greater sound through their confluence than the mere adding of their parts together.
And then some women start singing and ruin it.
Now, Wagner intended the low bass note to symbolize the flowing of the Rhine River, and the whole cycle is really an expression of paganism (as well as anti-Semitism). But I think the prelude -- with the low E-flat devloping into a complex and yet fully sonorous euphony -- illustrates the evolutionary concept that from a single and simple form of life all of the diversity of life on Earth arises, which fit together into an enormously complex ecosystem. Moreover, I also think this piece can equally illustrate God's creation of the universe: the E-flat is the ground or source or base (bass?), from which everything else flows. In that sense, it could almost be understood as neo-Platonic where all existence is an emanation or overflowing of the divine nature. Yet I still think it can be understood according to the Christian paradigm as well. You could call this piece "Genesis 1" without any incongruity.
In fact, to read even more into it, the fact that this piece can fit so easily with both interpretations may show that these two concepts -- evolution and creation -- are not in conflict at all. Indeed, when I listen to this piece, I think of God creating the universe via evolution.
You can listen to the Vorspiel here. If you're able to, turn the volume up as loud as you can, close your eyes, and make sure you're not interrupted for the next few minutes. It's just glorious.
