Early Paleo-Indians in North America are historically hypothesized to have been large-game specialists. Despite decades of research, Early Paleo-Indian diets are alternately portrayed as of either specialist or generalist. Though some suggest that these terms are not useful, debate over the nature of these diets continues. Authors who have studied Early Paleo-Indian archaeofaunas from North America have analyzed either a conservative dataset, consisting only of taxa whose remains meet criteria indicating they were part of Early Paleo-Indian diet, or a liberal dataset which includes all taxa regardless of the presence or absence of evidence that represented taxa were part of the diet. Camp sites are assumed to be more indicative of long-term, average Early Paleo-Indian diet, but single-event kill sites and multiple-event kill sites are included in analyses. Richness, evenness, and heterogeneity of mammalian taxa and of body size classes for conservative and liberal datasets show that many assemblages cannot be categorized as representing either specialist or generalist diets regardless of dataset used or diversity measure employed. Early Paleo-Indian diet breadth was diverse and in some cases more diverse than during the subsequent Archaic.
