How about this then -
Part of the report below - you can read in full on the link above -
" Given what’s known about the pace at which viral genomes mutate, if nCoV had been circulating in humans since significantly before the first case was reported on Dec. 8, the 24 genomes would differ more. Applying ballpark rates of viral evolution, Rambaut estimates that the Adam (or Eve) virus from which all others are descended first appeared no earlier than Oct. 30, 2019, and no later than Nov. 29.
The progenitor virus itself was almost certainly one that circulates harmlessly in bats (as SARS does) but has an “intermediate reservoir” in one or more animals that come into contact with people, Andersen said. Presumably, that reservoir is one of the species of animals at the Wuhan market thought to be ground zero for the outbreak. The ancestor of 2019-nCoV existed in that species for some unknown time, never infecting people, until by chance a single virus acquired a mutation that made it capable of jumping into and infecting humans.
The genome sequences suggest that was a one-time-only jump. “The genomes [from the 24 samples] are very uniform,” Andersen said. “If there had been multiple introductions,” including from many different animals, “there would be more genomic diversity. This was a single introduction.”
That means that what’s sustaining the spread is human-to-human transmission (suggesting that closing Wuhan’s animal market is very much an after-the-horse-has-fled-the-barn reaction). "
I’ve also read another scientific report, sadly didn’t ‘keep’, which stated categorically that because of the genome/dna the scientists were in no doubt that this was not, and could not have been created in a laboratory - that it would have been impossible. A nd that was a report by an internationakl team - not American - international.
