Shared intentionality may have been favored by persistence hunting in Homo erectus.

Abstract

Shared intentionality is the derived hominin motivation and skills to align mental states. Research on the role of interdependence in the phylogeny of shared intentionality has only considered the archeological record of Homo heidelbergensis. But ethnographic and fossil data must be considered, too. Doing so suggests that shared intentionality may have been favored in Homo erectus to support persistence hunting.
