The Bronze Age—Iron Age transition in Central Asia (ca. 800 BCE) was a period of significant cultural change that heavily influenced by greater population interaction and mobility. Indeed, scholars have increasingly emphasized the role “food globalization prehistory” has played defining this period. In mountain foothills Kazakhstan, culinary traditions from across Eurasia were combined through ...
Maize (Zea mays ssp. mays) is among the world's most important and ancient domesticated crops. Although the chronology of its domestication and initial dispersals out of Mexico into Central and South America has become more clear due to molecular and multiproxy archaeobotanical research, important problems remain. Among them is the paucity of information on maize's early morphological evolution...
Until recently, domestication has been interpreted as a rapid process with little predomestication cultivation and a relatively rapid rise of the domestication syndrome. This interpretation has had a profound effect on the biological framework within which investigations into crop origins have been carried out. A major underlying assumption has been that artificial selection pressures were subs...
Our understanding of the evolution of domestication has changed radically in the past 10 years, from a relatively simplistic rapid origin scenario to a protracted complex process in which plants adapted to the human environment. The adaptation of plants continued as the human environment changed with the expansion of agriculture from its centres of origin. Using archaeogenomics and computationa...
