 Thus, a second argument attempts to ground animalism’s defense in a broader naturalistic context. The “animal ancestors argument” takes the form of a reductio. If (1) is false and we are not animals, then nor are our parents animals, in which case nor are our parents’ parents, nor our parents’ grandparents, and so on, as far back as our ancestries extend. But in that case, the falsity of animalism entails the rejection of evolutionary theory (or at least that theory’s applicability to us), since it denies that our distant ancestries includes beings who were animals. But, since the rejection of evolutionary theory is too high a price to pay, it is instead the assumption of animalism’s falsity that ought to be rejected. Whilst Blatti (2012) argues that this argument withstands a number of extant objections, it also faces challenges (Daly and Liggins 2013, Gillett 2013).
