  The other option is to meet the challenge head-on and argue in the case of a particular moral theory that core moral truths in this theory would be stance-independent and also compatible with the Darwinian evolution of morals. David Copp (2008) pursues this course of argument using his society-centered moral theory sketched earlier. He argues that because moral truth on his theory concerns the needs of human society, one can expect that under propitious conditions the more biologically fit moral inclinations would tend to track (or “quasi-track,” his term) certain core moral truths. Copp’s argument is complex, but it presents a possible avenue of defense that is worth consideration.
