Yes, true.
A theory is as valuable in accordance with how much it explains.
I do not count miraculous explanations as a theory. Saying "and then a miracle happened" is not a theory. It is an article of faith.
Articles of faith have a different sort of validity, but are not science.
I tend toagree with that. I would like a more coherent theory explaining the Cambrian explosion for example.
Behavirial evolution makes more sense that the straight darwinian variety...I think.
