Evolution of the human capacity: The symbolic evidence

Abstract

Rare instances of symboling and problem-solving in the archaeological record of the European Acheulian and Mousterian suggest highly evolved potentially variable hominid capacities. These are aspects of capacity not evidenced in the lithic industries and habitation site complexes, and they cannot be determined from studies of comparative morphology or genetic distance. This sparse artifactual evidence cannot be quantified and is, in fact, statistically insignificant. Nevertheless, the internal cognitive contents and complexity evident in these unique materials reveal the presence of highly evolved skills and conceptual capacities involving the evaluation and use of diverse materials and processes. They also reveal a capacity for planning and mapping or modeling the territory and culture in time and space. Significantly, the evidence for these behaviors is richer in Europe during these early periods than in other areas of late hominid presence, including the Middle East and Africa where forms of anatomically modern humans were developing. It is possible that these early European efforts represent incipient and preparatory innovations that in some measure led to the regional “creative explosion” of the following European Upper Paleolithic. It is suggested that hominization selected for certain types and classes of problem-solving and symboling capacity and that the Neanderthals and anatomically modern humans each represent progressive advances over the evolved erectus capacity and its cultural manifests. It is also suggested that these late hominid capacities ultimately and evolutionarily derive from still earlier potential and variable problem-solving and conceptual capacities comparable to those found among the great apes.
