It is widely thought that causal cognition underpins technical reasoning. Here we suggest that understanding causal cognition as a thinking system that includes theory of mind (i.e., social cognition) can be a productive theoretical tool for the field of evolutionary cognitive archaeology. With this contribution, we expand on an earlier model that distinguishes seven grades of causal cognition, explicitly presenting it together with a new analysis of the theory of mind involved in the different grades. We then suggest how such (...) thinking may manifest in the archaeological or stone tool record and techno-behaviors of the last three million years or so. Our thesis is threefold: (a) theory of mind is an integral element of causal cognition; (b) generally speaking, the more advanced causal cognition is, the more it is dependent on theory of mind; and (c) the evolution of causal cognition depends more and more on mental representations of hidden variables. Ultimately, the final or seventh grade of causal cognition allows us to reason from a network of hidden variables that, amongst other things, enables the learning, manufacture, and use of complex technological systems. It also facilitates the seamless mapping of knowledge between personal (egocentric), physical, and social networks that allows for newly devised and innovative technical and social outcomes.

After we die, our persona may live on in the minds of the people we know well. Two essential elements of this process are mourning and acts of commemoration. These behaviors extend well beyond grief and must be cultivated deliberately by the survivors of the deceased individual. Those who are left behind have many ways of maintaining connections with their deceased, such as burials in places where the living are likely to return and visit. In this way, culturally defined places (...) often serve as metaphors of social association and shared experience. Humans are the only kind of animal that buries their dead, and this gesture is preserved in Paleolithic sites as early as 120,000 years ago. Though not the only method of honoring the dead in human cultures, the emergence of burial traditions in the Middle Paleolithic implies that both Neandertals and early anatomically modern humans had already begun to conceive of the individual as unique and irreplaceable. Claims of primitive mortuary behavior in earlier periods than the Middle Paleolithic fall short in that they lack any signs of positive social-spatial associations between the deceased and survivors. The archaeological evidence for burial behavior in the Middle Paleolithic provides the first clear translation of mourning into a stereotypical action. These burials therefore may represent the first ritualized bridge between the living and the deceased in human evolutionary history. (shrink)

Recently theorists have developed competing accounts of the origins and nature of protolanguage and the subsequent evolution of language. Debate over these accounts is lively. Participants ask: Is music a direct precursor of language? Were the first languages gestural? Or is language continuous with primate vocalizations, such as the alarm calls of vervets? In this article I survey the leading hypotheses and lines of evidence, favouring a largely gestural conception of protolanguage. However, the “sticking point” of gestural accounts, to use (...) Robbins Burling’s phrase, is the need to explain how language shifted to a largely vocal medium. So with a critical eye I consider Michael Corballis’s most recent expression of his ideas about this transition. Corballis’s view is an excellent foil to mine and I present it as such. Contrary to Corballis’s account, and developing Burling’s conjecture that musicality played some role, I argue that the foundations of an evolving musicality provided the means and medium for the shift from gestural to vocal dominance in language. In other words, I suggest that an independently evolving musicality prepared ancient hominins, morphologically and cognitively, for intentional articulate vocal production, enabling the evolution of speech.
