No evidence here, but it shouldn't be dismissed either.

In 2005, a group including researchers from the Wuhan Institute of Virology published research into the origin of the SARS coronavirus, finding that China's horseshoe bats are natural reservoirs of SARS-like coronaviruses.[6] Continuing this work over a period of years, researchers from the Institute sampled thousands of horseshoe bats in locations across China, isolating over 300 bat coronavirus sequences.[7]
In 2015, the Institute published successful research on whether a bat coronavirus could be made to infect HeLa. A team from the Institute engineered a hybrid virus, combining a bat coronavirus with a SARS virus that had been adapted to grow in mice and mimic human disease. The hybrid virus was able to infect human cells.[8][9]
