Secrets of the ‘lost crops’ revealed where bison roam

Research from Washington University in St. Louis helps flesh out the origin story for the so-called “lost crops” of the Midwest and Northeast. These plants that may have fed as many Indigenous people as maize, but until the 1930s had been lost to history. Natalie Mueller, assistant professor of archaeology in Arts & Sciences at Washington University in St. Louis, shares evidence that bison were “co-creators” — along with Indigenous peoples — of landscapes of disturbance that gave rise to greater diversity and more agricultural opportunities.

More questions than answers as mystery of domestication deepens

A recent interdisciplinary conference that led to the publication of a special issue of PNAS on domestication raised more questions than it answered. Washington University in St. Louis scientists Fiona Marshall and Ken Olsen, who participated in the conference and contributed to the special issue, discuss some of the key questions that have been raised about this pivotal event in human history.

A review of recent research on the domestication of large herbivores for “The Modern View of Domestication,” a special feature of PNAS, suggests that neither intentional breeding nor genetic isolation were as significant as traditionally thought. 

Rice domestiction confiirmed genetically

Jason Londo, Washington University in Arts & Sciences biology doctoral candidate, and his adviser, Barbara A. Schaal, Ph.D., Washington University Spencer T. Olin Professor of Biology in Arts & Sciences, ran genetic tests of more than 300 types of rice, including both wild and domesticated, and found genetic markers that reveal the two major rice types grown today were first grown by humans in India and Myanmar and Thailand (Oryza sativa indica) and in areas in southern China (Oryza sativa japonica).
