The recency and geographical origins of the bat viruses ancestral to SARS-CoV and SARS-CoV-2
Recombination-aware evolutionary analyses of the entire genomes of SARS-CoV-1-like and SARS-CoV-2-like viruses indicate that SARS-CoV-1 and SARS-CoV-2 descend from bat coronaviruses that circulated as recently as one to six years before their respective dates of human emergence. These inferred virus ancestors likely needed to travel faster than closely related bat viruses in order to reach their respective sites of emergence.
