Homo artifex
While stone tools provide only the narrowest keyhole view of the lives of our ancestors, new theory and methods that explicitly focus on the interaction of organisms and environments over time—niche construction, the evolution of development, phenotypic accommodation, and gene–culture co-evolution—provide opportunities for squeezing “mind” from enigmatic stones. Tool-making, like language and theory of mind, is a culturally transmitted skill acquired through extended practice. It is also a key component of a human cultural niche that supports our unique adaptive strategy of large brains, cooperative breeding, and extended development. As discussed in this chapter, by deploying methods from the neural and behavioral sciences to better understand this archaeologically visible behavior, we can hope to more broadly illuminate the evolution of the human mind, brain, and culture.
