This is why there has been a lot of attention on certain animals, such as raccoon dogs and minks. It turns out that a lot of the early infections linked to the various Wuhan markets were from shop owners and employees who either sold or were in close contact a small number of animal species. It also turns out that these animals can be infected by SARS-CoV-2. See https://ncrc.jhsph.edu/research/animal-sales-from-wuhan-wet-....
The issue is that (as far as I'm aware) there's no immediate evidence that SARS-CoV-2 jumped to humans from any of these animals, only that there was an (again, as far as I'm aware) unknown intermediary species. However, because the animals at the wet market were disposed of, there's no way to definitively link SARS-CoV-2 to them.
