The bottle gourd (Lagenaria siceraria) has been cultivated for at least 10,000 years and was the only plant species cultivated in both the Old and New Worlds before Columbus; in this sense, it can be considered the world’s first global crop. Its durable fruit shells are used for containers, apparel and musical instruments throughout the tropics, subtropics and some temperate zones worldwide. Despite the importance of bottle gourd, its distribution across many cultures, and a long-standing...
Further evidence for a terrestrial-focused protein diet in prehistoric Rapa Nui (2015)
Previous analyses of subsistence activities on Rapa Nui generated new classes of data to explain human persistence on this remote, subtropical and ecologically-marginal island. Even compared to other small to medium-sized islands in Eastern Polynesia, Rapa Nui appears anomalous for: 1) an apparent shift away from marine protein sources, determined from stable isotope analysis of bone collagen, and 2) a far greater reliance on a single terrestrial carbohydrate (Ipomoea batatas), determined from...
Genetic Variation and Sociocultural Dynamics in Two Early Christian Cemeteries from Kulubnarti (2019)
This is an abstract from the "Ancient DNA in Service of Archaeology" session, at the 84th annual meeting of the Society for American Archaeology. Skeletal remains from two contemporaneous Early Christian Period (550–800 CE) cemeteries at Kulubnarti in Sudanese Nubia have been the subject of a decades-long biocultural research program. Craniometric and dental analyses have suggested biological similarity between members of the "R" and "S" cemetery communities, while analyses of health and...
The ones who stayed behind? Genome-wide affinities of Okunev remains from Bronze Age South Siberia and the enduring dialogue of ancient DNA and physical anthropology. (2017)
Genome-wide ancient DNA data from Upper Paleolithic Siberians and deep time series in Europe challenge many traditional models of relationships between Native Americans, West Eurasians, and East Asians — commonplace units in physical anthropology — by recasting them as fusions of prehistoric ancestry streams that may unexpectedly cross-cut or fracture these categories. We evaluate new and published genome-wide data from remains attributed to Okunev — an archaeological culture of the Middle...
West to east - the spread of wheat and barley cultivation across Eurasia (2015)
By the end of the 2nd millennium BC, the South-west Asian crops wheat (Triticum spp.) and barley (Hordeum vulgare) are being cultivated in much of Central, South and East Asia. How did these crops spread from west to east? Can we find evidence of the routes of spread through the archaeogenetic analysis of these South-west Asian cereals? We describe our analyses of Eurasian barley and wheat using microsatellite and Single Nucleotide Polymorphisms (SNPs); this data is enabling us to elucidate...
