Neil S, Montgomery J, Evans J, Cook GT, Scarre C. 2017. Land use and mobility during the Neolithic in Wales explored using isotope analysis of tooth enamel. American Journal of Physical Anthropology
The nature of land use and mobility during the transition to agriculture has often been debated. Here, we use isotope analysis of tooth enamel from human populations buried in two different Neolithic burial monuments, Penywyrlod and Ty Isaf [see Nearby Site list above - Ed], in south-east Wales, to examine patterns of land use and to evaluate where individuals obtained their childhood diet.
The strontium isotope results suggest that the majority of individuals buried at Penywyrlod did not source their childhood diet locally. One individual in this group has strontium isotope ratios that exceed all current known biosphere values within England and Wales. This individual is radiocarbon dated to the first few centuries of the 4th millennium BC, consistent with the period in which agriculture was initiated in Wales: the results therefore provide evidence for migration during the transition to farming in Wales. In contrast, all individuals sampled from Ty Isaf post-date the period in which agriculture is considered to have been initiated and could have sourced their childhood diet from the local region in which they were buried
