The coronavirus pandemic circling the globe is caused by a natural virus, not one made in a lab, a new study says. The virus’s genetic makeup reveals that SARS-CoV-2 isn’t a mishmash of known viruses, as might be expected if it were human-made. And it has unusual features that have only recently been identified in scaly anteaters called pangolins, evidence that the virus came from nature, Kristian Andersen and his colleagues report March 17 in Nature Medicine.
