Ellis. “Archaeological assessment reveals Earth’s early transformation through land use.” Science Vol. 365, Issue 6456, pp. 897-902.
Humans began to leave lasting impacts on Earth’s surface starting 10,000 to 8000 years ago. Through a synthetic collaboration with archaeologists around the globe, Stephens et al. compiled a comprehensive picture of the trajectory of human land use worldwide during the Holocene (see the Perspective by Roberts). Hunter-gatherers, farmers, and pastoralists transformed the face of Earth earlier and to a greater extent than has been widely appreciated, a transformation that was essentially global by 3000 years before the present.

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

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
