I think you raise an interesting question. Let me try
rephrasing it, hopefully without destroying your intent.
Suppose we limit ourselves to the most "interesting"
results of evolution. Things that Dawkins would say
appear to have been designed for a purpose. Or,
better stated, adaptations. Cases where there seems
to be a fine-tuning between form and function.
Are there any scientific explanations for adaptations
other than natural selection?
