Source? Definitely some experts think it is not impossible that it was brought to the wet market very early in the outbreak, that's not implausible at all. But the idea that it was circulating globally or widely at all before that is not backed by the evidence.

There are some Brazilian researchers in the process of mapping the whole genome of some samples collected and frozen back in November 2019 that they believe to be SARS-CoV-2.

It will be interesting to see how that compares to a Wuhan sample and see if it had most of the novel features of COVID-19, but is maybe missing one thing like how it binds to ACE2 which is probably implicated in all the cardiovascular issues it causes.
