"We used detailed phylogenetic analysis, ancestral sequence reconstruction, & molecular dynamics simulations to examine the Spike-RBD functional evolution, finding to our surprise that it has likely possessed high affinity for hACE2 since at least 2013."

biorxiv.org/content/10.110…
"If this is the case – that this viral lineage possessed the ability to bind hACE2 with high affinity
for at least the past 7 years – then why did it not emerge as a public health issue until recently?"
"One possibility is that binding hACE2 by the Spike-RBD is not sufficient, on its own, to
infect humans, and that other molecular components first needed to acquire new functions to do so."

My search for State Key Laboratory of Virology, WIV yielded some...interesting results

The main research directions of the laboratory:

To study the cross-species transmission mechanism of SARS virus, and new strategies for viral suppression of HIV, among other things (in pic)
The laboratory has the Chinese Type Culture Collection Center, Chinese Virus Resource & Information Center (the largest virus depository in Asia); 1 BSL-4 lab, 2 BSL-2 lab, 1 BSL-3, and 1 ABSL-3 animal lab located at the Wuhan University.

On December 2019, China's first "Vaccine Management Law" was officially implemented in all BSL-3 & above labs, including the ABSL-3 lab at Wuhan Uni.

So far, the ABSL-3 lab has completed AIDS, TB, SARS & other experiments on more than 1,300 monkeys.

More on Wuhan CDC:

WHCDC was only ~280 meters from the Wuhan seafood market. It is well known but what's relatively little known is that it was also adjacent to the Union Hospital where the first
group of doctors were infected during this epidemic. (See figure, bottom)
Tissue samples and trashes near the WHCDC
were found contaminated with SARS-CoV-2.

US State Department Cables in 2018 had noted safety concerns at WHCDC (and WIV).
