Showing off, Foraging Models, and the Ascendance of Large-Game Hunting in the California Middle Archaic

Abstract
In a recent paper in American Antiquity (2002:231-256), Hildebrandt and McGuire argue that archaeofaunal patterns in California document an ascendance of artiodactyl hunting during the Middle Archaic. They also suggest that such a trend is inconsistent with predictions derived from optimal-foraging models. Given the apparent failure of foraging theory, they advance a “showing off” model of large-game hunting. While their presentation is intriguing, we do not see a theoretical warrant for predicting that show-off hunting would have increased during the Middle Archaic. We present here an alternative hypothesis for the increase in artiodactyl abundances and the hunting-related patterns they identify. That hypothesis follows directly from the prey model itself under what appears to have been a dramatic artiodactyl population expansion after the drought-dominated middle Holocene period.
