At what level do you want an explanation? If the explanation is presented at the level of chemistry, it is reductionism. If the explanation is presented at the level of population genetics it is a just so story.

We have been around and around with this. Science investigates phenomena with the tools available at the time, and scientific explanations are sometimes just formal descriptions of relationships among phenomena.

There is nothing in the behavior of genes that suggests that their behavior can't be explained with the methods of biochemistry. There is nothing about the frequency or distribution of alleles that suggests anything is at work other than selection.

How strange. I made a reply to you - I thought - and looking back now, it is not here. I must have mashed "x" instead of "post" LOL!

I'd prefer ontological though it will be hard for us to navigate the "what is all that there is" part of agreeing to terms.
