Would Darwin be a moral naturalist?

His following qoute is often recycled, that goes something like, 'had we been reared under the conditions of hive bees.. we would think it moral to do x' 
The point is, it seems to me, that something about our inherited nature constrains or determines what is moral for a being like us. So, would Darwin have taken this to mean that we ought to be anti-realists - because moral goodness is fixed to our nature and since nature could have been anything, so could have our concept of goodness been anything - OR would this be a kind of mind-independent natural fact - it is true by definition that we moral goodness is X for beings like Y, and X is therefore true independently of Y.

Moral realism is the position that moral sentences express propositions that refer to objective features of the world. Darwin's observations about where our moral beliefs come from have no bearing on whether moral realism is true or not. This is because an explanation of why someone believes X is not the same as an explanation of why X is (or is not) true.
