One of our species’ signature capacities, Deacon argues, is symbol-usage. Symbols permeate our practices to such an extent that even our success in mating depends on our acquiring complex social skills for negotiating symbolically mediated transactions. “Thus,” he avers, “because of symbols and with the aid of symbols, Homo sapiens has been self-domesticated and adapted to a niche unlike any other that ever has existed. We have been made in the image of the word.”
