Diet breadth (Other Keyword)

Identifying the causes of spatiotemporal variation in technological richness and complexity is an important task for archaeology. James O’Connell has proposed that diet breadth can be expected to affect investment in subsistence technology and therefore the number and intricacy of subsistence tools. Narrower diets, he suggests, will be associated with lower investment and therefore fewer and/or less complex tools, while broader diets will be associated with higher investment and therefore more...
Diet Breadth Narrowing at the Pleistocene/Holocene Transition: Faunal Evidence from Dust Cave, Alabama (2015)
Paleoenvironmental data from the Younger Dryas and Early Holocene indicate that plant and animal communities in the southeastern United States changed substantially between these periods. These reconstructions indicate that during the Early Holocene, climatic amelioration and changes in forest composition may have led to increases in populations of large-bodied animals that were depressed during the Younger Dryas. Based on these data, I hypothesized that there would have been a narrowing of diet...
