我覺着進化(論)是機制之一，或階段之一，而遠非全部成因；但也不可能不是成因之一。

Forming of the physical world is probably way more intricate and subtler than the way in which our mind attempts to manipulate it.  There are many mechanisms that can't be abruptly identified as "evolutionary".

The human mind tends to simplify things.  One can see this in the developments of physics and mathematics. Biology shouldn't be expected to be an exception.
