Detecting spatially local deviations in population change using summed probability distribution of radiocarbon dates (2017)

DOCUMENT Citation Only Enrico Crema. Stephen Shennan.

The increasing availability of large radiocarbon databases encompassing continental geographic scales (e.g. CARD, EUROEVOL, AustArch, etc.) is now opening new possibilities for evaluating spatial variation in prehistoric population. We have, for the first time, the opportunity to determine whether and when different geographic regions experienced distinct demographic patterns using an absolute chronological framework. This line of research is however hindered by spatially uneven sample sizes...

MID-LATE HOLOCENE POPULATION TRENDS AND MARITIME RESOURCE INTENSIFICATION IN WESTERN ALASKA (2017)

DOCUMENT Citation Only Andrew Tremayne. William Brown.

Population growth has long been argued to play a critical role in promoting cultural evolution, operating both through adaptation to population pressure and increasing social network size and transmission frequency. We present a model of mid-late Holocene Alaskan population size based on a temporal frequency analysis of 902 site occupation episodes dating between 6000 and 1000 radiocarbon years BP, with two objectives: (1) identify factors that influenced Alaskan population dynamics over this...
