Sure, here you go: https://arxiv.org/abs/2005.06199 https://arxiv.org/abs/2005.06199 This uses a rigorous bioinformatic analysis to demonstrate that the SARS-CoV-2 spike protein has dramatically stronger binding affinity for human ACE2 than any other known version of the protein. This is the case for the version of the protein observed at the very beginning of the outbreak. The virus evolves slowly, so this implies a very long period of transmission in human cells, which is compatible with a zoonotic transfer much earlier than expected (possibly many years) or gain of function experiments in cell cultures. As a biologist, I find this to be sufficient factual information to motivate a discussion about the possible origins of the virus.
