 However, other researchers have recently contested the claim that overimitation is strictly absent in non-humans (Andrews 2017). This is one front of a much larger debate over which features of human psychology are unique to our species, and which are shared with others. Recent work relevant to norms has focused on whether and to what extent species other than humans have the capacities to sustain cumulative culture (Dean et al. 2014), with plausible cases being made that the basic psychological wherewithal is present not just in some great apes but also in songbirds (Whiten 2019) as well as whales and dolphins (Whitehead &amp; Rendell 2015). Another area of focus has been on aspects of moral cognition, where much illuminating work has explored the continuities between humans and other animals (de Waal 2006; Andrews &amp; Monsó forthcoming). Much of this is relevant to, but does not directly address, the question of whether a psychological capacity dedicated to norms is distinctively human, or which of its component mechanisms might be present in rudimentary form in other animals. Some have suggested that the propensity to punish, and especially the tendency for third party sanctioning of norm violations, is not found in other species (Riedl et al. 2012; Prooijen 2018, though see Suchak et al. 2016). Others point to humans’ exceptional ability to cooperate and their resulting ecological dominance, suggesting it provides indirect evidence for the uniqueness of our capacities for culturally transmitted norms (J. Henrich 2015; Boyd 2017). Not all are convinced, arguing that animals like elephants (Ross 2019) and chimpanzees (von Rohr et al. 2011) exhibit socially sophisticated behaviors best explained by the presence of psychological precursors to core components of the human norm system. Important preliminary progress has been made on this cluster of questions concerning non-human normativity (Vincent, Ring, &amp; Andrews 2018; Andrews 2020; Fitzpatrick forthcoming), but much conceptual and empirical work remains to be done.
