Spengler, Robert N., III and Natalie Mueller (2019) The Unexplored Role of Endozoochoric Seed Dispersal in the Domestication of Grain Crops. Nature Plants. 5: 656–662.
In addition to large-seeded cereals, humans around the world during the mid-Holocene started to cultivate small-seeded species of herbaceous annuals for grain, including quinoa, amaranth, buckwheat, the millets and several lost crops domesticated in North America. Continue reading

Spengler, Robert N., III, Ilaria de Nigris, Barbara Cerasetti, Marialetizia Carra, Lynne M. Rouse (2018) The breadth of dietary economy in Bronze Age Central Asia: Case study from Adji Kui 1 in the Murghab region of Turkmenistan. Journal of Archaeological Science: Reports 22: 372-381.
Over the past decade research into the paleoeconomy of Bronze Age (3500-800 B.C.) peoples in Central Asia has shown how complex the productive economy was. The agropastoral system involved an array of crops and herd animals. In this article, we present a paleoethnobotanical study conducted on sediment samples from excavation units at the site of Adji Kui, Turkmenistan. Continue reading

During the first millennium A.D., Central Asia was marked by broad networks of exchange and interaction, what many historians collectively refer to as the “Silk Road”. Much of this contact relied on high-elevation mountain valleys, often linking towns and caravanserais through alpine territories. This cultural exchange is thought to have reached a peak in the late first millennium A.D., Continue reading
Spengler, Robert N., III (2018) Vegetation History and Archaeobotany.
In the early 1980s Naomi Miller changed the field of palaeoethnobotany; her research into whether the ancient seed eaters of southwest Asia were human or herbivore opened an ongoing debate over the impact that burning of animal dung had on the formation of archaeobotanical assemblages, and how researchers can differentiate between human and animal food remains.
