In June, the World Health Organization recommended that scientists continue to research all possible origins of the Covid-19 pandemic, including a lab leak. Two newly published studies take totally different approaches but arrive at the same conclusion: The Huanan Seafood Market in Wuhan, China, was most likely the epicenter for the coronavirus.
