Two new scientific papers claim that the Covid19 causing coronavirus came from the Huanan Seafood Market in Wuhan, China. But lab-leak theory hasn't been disproven.

The coronavirus pandemic began in separate viral spillovers - at least two but perhaps as many as two dozen - from live animals sold and butchered in late 2019 at the Huanan Seafood Market in Wuhan, China, according to two papers published Tuesday in the journal Science.

The publication of the papers, which underwent five months of peer review and revisions by the authors, is unlikely to quell the rancorous debate about how the pandemic began and whether the virus emerged from a Chinese laboratory. And the authors acknowledge there are many unknowns requiring further investigation - most notably, which animals were involved.
