We heard so much about the new coronavirus originating from the Wet Market in Wuhan. However, the study of the genomic data
https://www.researchgate.net/public...virus_SARS-CoV-2_using_the_whole_genomic_data
suggests the strain of the virus found in the market evolved from other strains found elsewhere, not the other way around:
"Did someone encounter or eat a pangolin elsewhere in Wuhan away from the Huanan Seafood Market, contract SARS-CoV-2, travel around the city infecting others, then go to the market and set off the bigger outbreak? And from that, they ended up contracting a strain of the coronavirus that originated in bats was unrelated to the research on coronaviruses in bats going on in two major laboratories in the city? It is possible, but it is a remarkable sequence"https://www.nationalreview.com/the-morning-jolt/tracing-the-viruss-origins/

suggests the strain of the virus found in the market evolved from other strains found elsewhere, not the other way around:
By applying the reported bat coronavirus genome (bat-RaTG13-CoV) as the outgroup, we found that haplotypes H13 and H38 might be considered as ancestral haplotypes, and later H1 (whose descendants included all samples from the Huanan Seafood Wholesale Market) was derived from the intermediate haplotype H3. The population size of the SARS-CoV-2 was estimated to have undergone a recent expansion on 06 January 2020, and an early expansion on 08 December 2019. Phyloepidemiologic analyses suggested that the SARS-CoV-2 source at the Huanan Seafood Wholesale Market was potentially imported from elsewhere. The crowded market then boosted SARS-CoV-2 circulation and spread it to the whole city in early December 2019.
