Religions do not evolve

You're scope is somewhat limited. I believe Richard Dawkins has addressed this issue numerous times with the subject of memes and the extended phenotype. Anything that replicates can evolve, including ideas. I would even go as far to say that the evolution of ideas provides the most compelling evidence yet that Charles Darwin's core concept of evolution is true. We have reams of written text that are analogous to the GATC of the DNA Sequence. Subtle changes to a sentence can have fundamental repercussions. Jesus once walked by the water. Then he walked on the water and set in motion 2000 years of what we now call history.

To suppose that ideas and opinions (as we've discussed before) do not have a real effect on the world is an exercise in switching one's brain off and shutting out the truth. Evolution is not simply a case of growing a third arm, or how eyeballs came into existence.

It may be true that religions eventually become quaint and irrelevant, but that proves bugger all. Red Squirrels have become quaint and irrelevant because Grey squirrels have out-evolved them. We humans are whipper-snappers of a species compared to many other lifeforms on the planet. Who's to say we won't become quaint and irrelevant in a few years time?

Now, about my "God is a computer" hypothesis.....?
