The entire COVID-19 genome has been sequenced and compared to known viruses.
"Phylogenetic analysis of the complete viral genome (29,903 nucleotides) revealed that the virus was most closely related (89.1% nucleotide similarity) to a group of SARS-like coronaviruses (genus Betacoronavirus, subgenus Sarbecovirus) that had previously been found in bats in China" [0]
"This phylogeny shows evolutionary relationships of HCoV-19 viruses from the ongoing novel coronavirus COVID-19 pandemic. All [148] samples are still closely related with few mutations relative to a common ancestor, suggesting a shared common ancestor some time in Nov-Dec 2019. This indicates an initial human infection in Nov-Dec 2019 followed by sustained human-to-human transmission leading to sampled infections."[1]
