Full-genome evolutionary analysis of the novel corona virus (2019-nCoV) rejects the hypothesis of emergence as a result of a recent recombination event

Does he mean recombination event in nature or event in a lab.

Thanks for the link. The conclusion says this:

Conclusions:

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.

______________________________

So, let me, as a lay person make this observation:

1) There are known two variants: 2019-nCoV and RaTG13

2) 2019-nCov is the one that caused the current worldwide outbreak and it originated from bats.

Which leads to this question : what about the other variant: RaTG13?

* Do we KNOW of any human infection cases coming from this strain?

* Where did RatG13 originate from? Lab grown?
