Biodiversity in Agriculture
Origins of African Plant Domestication
The Origins of Agriculture and Settled Life
Crops & Man
Evidence for cultivation of sesame in the ancient world
Lettuce and the Sycomore
The Distinguished economic botanist award 1985
Patterns of morphological variation insesamum indicum
Introduction of soybean to North America by Samuel Bowen in 1765
Nuba agriculture and ethnobotany, with particular reference to sesame and sorghum
The Garden of the Lord
The first urbanization of the Palestine region began in the late centuries of the fourth millennium B.C. East of the Jordan, urbanism collapsed at the end of Islamic Medieval times and tent dwellers largely occupied the land until World War I. The seven or so centuries without urban disturbance provides an excellent trajectory for visualizing the situation as it probably was before urbanization began. Nineteenth century travelers have given excel…
Origins of African Plant Domestication
Literature review and numerical taxonomy ofEragrostis tef (T’ef)
The Origins of Cereal Agriculture in the Old World
The morphology and domestication of pearl millet
The sorghums of ethiopia
Farming in Prehistory
Caudatum sorghums and speakers of Chari-Nile languages in Africa
Our study of caudatum sorghums in Africa and the ethnography, history, and archaeology of regions where caudatum sorghums are grown has led us to the following conclusions. The distributions of caudatum sorghums and Chari-Nile-speaking peoples coincide so closely that a causal relationship seems probable. Caudatum sorghums appear to be a product of selection by Chari-Nile-speaking peoples for a hardy crop which will produce a large amount of grai…
Weeds and Domesticates
On the Quality of Evidence for Origin and Dispersal of Cultivated Plants [and Comments and Reply]
Sources of evidence for origin and dispersal of cultivated plants are tabulated and classified. All items are qualified, and the level of confidence with which an item of evidence can be accepted varies accordingly. Qualifications are listed as (1) authenticity, (2) abundance, (3) kind, (4) interpretation, and (5) integration. Theories proposed are often based on evidence of very dubious quality; it is suggested here that a more disciplined appro…
Agricultural Origins: Centers and Noncenters
I propose the theory that agriculture originated independently in three different areas and that, in each case, there was a system composed of a center of origin and a noncenter, in which activities of domestication were dispersed over a span of 5,000 to 10,000 kilometers. One system includes a definable Near East center and a noncenter in Africa; another system includes a North Chinese center and a noncenter in Southeast Asia and the South Pacif…
