Soybean adoption came early by many cultures: Human domestication of soybeans is thought to have first occurred in central China some 3,000 years ago, but archaeologists now suggest that cultures in even earlier times and in other locations adopted the legume (Glycine max).
Comparisons of 949 charred soybean samples from 22 sites in northern China, Japan and South Korea - found in ancient households including hearths, flooring and dumping pits - with 180 modern charred and unburned samples were detailed in the journal PLoS ONE. The findings, say lead author Gyoung-Ah Lee, an archaeologist at the University of Oregon, add a new view to long-running assumptions about soybean domestication that had been based on genetic and historical records...
