I have something of a different take on it.
Theistic evolution to me doesn't really suggest Darwin's evolution.
But rather, how religion itself evolves over time.
Example, a religion usually starts small. Sometimes, such as in Christianity, it starts out with different sects. Then one sect dominates the other sects or wipes them out, becoming the dominant religion. Then over time people become dissatisfied and some rebel against it creating a protestant movement. And more and more sects of the religion are created. Some of those religious beliefs even affect society and government and continue to to this day.
Because for me, evolution is not compatible with creationism. Creationism states that God creates everything out of thin air at every single step of the way, rather than small incremental steps over time.
Which, incidentally, beats me why he would require humanity to give birth since he can just poof things out of thin air. In a similar vein, if he can just poof things out of thin air, why would he have the need to require things to change slowly over time?
