Update of Coronovirus research…
Searched https://www.biorxiv.org and got 60 hits. Keep in mind that this is a preprint site and these papers aren't vetted.
Noticed this in one paper:
Title: Full-genome evolutionary analysis of the novel corona virus (2019-nCoV) rejects the hypothesis of emergence as a result of a recent recombination event
But the conclusion says:
The levels of genetic similarity between the 2019-nCoV and RaTG13 suggest that the latter does not provide the exact variant that caused the outbreak in humans, but the hypothesis that 2019-nCoV has originated from bats is very likely. We show evidence that the novel coronavirus (2019-nCov) is not-mosaic consisting in almost half of its genome of a distinct lineage within the betacoronavirus. These genomic features and their potential association with virus characteristics and virulence in humans need further attention.
"Very Likely" is not a rejection of he hypothesis of emergence as a result of a recent recombination event. Having levels of geneti similarity between the two strains doesn't mean it can't be man-made in some areas.
But I'm not a medfag, just an engineer who can read science papers.
Maybe a real medfag can do some digging into these papers? No one seems to be quoting actual research papers in the media discussions (not surprised).
