The development of cognitive capacities depends on environmental conditions, including various forms of scaffolding. As a result, the evolution of cognition depends on the evolution of activities that provide scaffolding for cognitive development. Non-human animals reared and trained in environments heavily scaffolded with human social interaction can acquire non-species-typical knowledge, skills, and capacities. This can potentially shed light on some of the changes that paved the way for the evolution of distinctively human behavioral capacities such as language, advanced social cognition, (...) and elaborate forms of tool craft. In this light, I revisit several widely known—but also widely misunderstood—cases of exceptional animals and argue that each of these cases provides clues about key innovations in our own evolutionary history.

Typically in the philosophical literature, kinds of minds are differentiated by the range of cognitive tasks animals accomplish as opposed to the means by which they accomplish the tasks. Drawing on progress in cognitive ethology (the study of animal cognition), I argue that such an approach provides bad directions for uncovering the mark of the human mind. If the goal is to determine what makes the human mind unique, philosophers should focus on the means by which animals interact with objects (...) in their environments, and not on the sorts of tasks they are able to accomplish.

I argue that an explicit distinction between cognitive characters and cognitive phenotypes is needed for empirical progress in the cognitive sciences and their integration with evolution-guided sciences. I elaborate what ontological commitment to characters involves and how such a commitment would clarify ongoing debates about the relations between human and nonhuman cognition and the extent of cognitive abilities across biological species. I use theoretical proposals in episodic memory, language, and sociocultural bases of cognition to illustrate how cognitive characters are being (...) introduced in scientific practice. (shrink)

Disagreement remains about whether particular human socio-cognitive traits arose primarily as a result of biological adaptations, or because of changing cultural practices. Heyes argues that uniquely human traits, including imitation and theory of mind, are the product of cultural learning. In contrast, Tomasello argues that they are, in key respects, part of a suite of adaptations for ‘shared intentionality’. We consider how such disagreements might be resolved. We show that the kinds of consideration often used to adjudicate questions about trait (...) origins are insufficient to settle origin questions. Furthermore, humankind’s immersion in culture undermines the prospect that cross-cultural and developmental studies could resolve origin questions. Nonetheless we argue that, when cautiously interpreted, currently neglected studies of enculturated great apes (i.e. apes raised in human environments) can shed new light on trait origins, and inform mechanistic accounts of cognitive development. While acknowledging the shortcomings of enculturation research, we argue that it deserves renewed attention. (shrink)
