Okay, this is going to be short as I'm really not a rabbi.
But the short of it, is NO, it's not apikorsus.
Basically, how the world was created et al, and with what process, isn't relevant. The point is that there is a god who created it behind it. If you look at what they write, they say that there isn't, it just happened, there is no way for it to just happen, no way for anything to just happen. If you want can send this on, I think I actually will, but basically, yes, it is fact that the fittest survive.
I will send this on because I want you to have real answers, I definitely don't know enough and am way too confused about enough that I could never really answer
