Three teams of researchers working independently have conducted three specific studies of ruminants—a class of mammals that obtains nutrients from plants by fermenting it in chambered stomachs. The work was part of an overall project called, quite naturally, the Ruminant Genome Project. All three teams were made up of members from several institutions in China and a few other countries. All three groups have published their findings in the journal Science. Also, Dai Fei Elmer Ker and Yunzhi Peter Yang with the Chinese University of Hong Kong and Stanford University, respectively, have published a Perspective piece outlining the work by the three teams in the same journal issue.
