The emergence of complexity and novelty in the human fossil record
Outside of possible evidence for more complex social practices (e.g. longevity post-trauma, preserved infant remains), the fossil record of human evolution is limited in its ability to address the transition towards transcendental forms of wisdom. Indeed, it is difficult to equate our modern intellectual condition with deep past biological indicators at all. Nonetheless, arguably the best and most visible evidence for biological changes that might be precursors to these abilities are in the form of increasing complexity and/or novelty. These patterns are seen in the hominin fossil record most strongly at the emergence and diversification of our genus, and in the Middle to Late Pleistocene record with the emergence of our species. This chapter will first give a brief overview of the human fossil record, and will then focus on these two time periods and the question of what produces such complexity/novelty.
