The nematode Caenorhabditis elegans is extensively used as a model organism in biology. The Biodiversity Research Center of Academia Sinica and international research teams, discovers a new species named C. inopinata. The high level of genetic similarity between C. elegans and C. inopinata creates a great scope for comparative studies on the biology, genetics, ecology and evolution. The result was published in Nature Communications on Aug 10, 2018.
