There are outstanding evolutionary questions on the recent emergence of human coronavirus SARS-CoV-2 including the role of reservoir species, the role of recombination and its time of divergence from animal viruses. We find that the sarbecoviruses—the viral subgenus containing SARS-CoV and SARS-CoV-2—undergo frequent recombination and exhibit spatially structured genetic diversity on a regional scale in China. SARS-CoV-2 itself is not a recombinant of any sarbecoviruses detected to date, and… Expand

Figures from this paper

On the origin and evolution of SARS-CoV-2
TLDR
The spike (S) protein of SARS-CoV-2, which enables the virus to enter host cells, exhibits signatures of both purifying selection and ancestral recombination events, leading to an effective S protein capable of infecting human and many other mammalian cells. Expand
Recombination and lineage-specific mutations linked to the emergence of SARS-CoV-2
TLDR
Recon reconstructing the evolutionary events that have accompanied the emergence of SARS-CoV-2, with a special emphasis on the RBD and its adaptation for binding to its receptor, human ACE2, suggests that the recombination event involving ancestral strains of SAR's co-infected strains led to an increased affinity for hACE2 binding and that alleles 427N and 436Y significantly enhanced affinity as well. Expand
Recombination and lineage-specific mutations linked to the emergence of SARS-CoV-2
TLDR
Common mechanisms involved in the emergence of human-infecting SARS-like viruses are demonstrated, by acquiring a common haplotype in the RBD through recombination, and further, through increased specificity to the human ACE2 receptor through lineage specific mutations. Expand
The evolutionary history of ACE2 usage within the coronavirus subgenus Sarbecovirus
TLDR
It is shown that the lineage that includes SARS-CoV-2 is most likely the ancestral ACE2-using lineage, and that recombination with at least one virus from this group conferred ACE2 usage to the lineage including Sars- CoV-1 at some time in the past. Expand
Evolutionary trajectory of SARS-CoV-2 and emerging variants
TLDR
The origins of all known HCoVs are highlighted, and a map positively selected for mutations within HCoV proteins is mapped to discuss the evolutionary trajectory of SARS-CoV-2. Expand
Exploring the natural origins of SARS-CoV-2 in the light of recombination
TLDR
It is concluded that there has been relatively recent geographic movement and co-circulation of these viruses’ ancestors, extending across their bat host ranges in China and Southeast Asia over the last 100 years or so. Expand
Mapping genome variation of SARS-CoV-2 worldwide highlights the impact of COVID-19 super-spreaders.
TLDR
Phylogenetic analysis indicates a TMRCA for SARS-CoV-2 genomes dating to 12 November 2019 - thus matching epidemiological records and revealing a rather uniform mutation occurrence along branches that could have implications for diagnostics and the design of future vaccines. Expand
A novel SARS-CoV-2 related coronavirus in bats from Cambodia
TLDR
The identification of SARS-CoV-2 related coronavirus in two Rhinolophus shameli bats sampled in Cambodia in 2010 is described and it is suggested that Southeast Asia represents a key area to consider for future surveillance for coronaviruses. Expand
Synonymous mutations and the molecular evolution of SARS-CoV-2 origins
TLDR
A detailed analysis of the synonymous divergence, which is less likely to be affected by selection than amino acid divergence, between human SARS-CoV-2 and related strains suggests that the vast majority of nonsynonymous mutations currently segregating within the human strains have a negative impact on viral fitness. Expand
No detectable signal for ongoing genetic recombination in SARS-CoV-2
TLDR
The extant genomic diversity of SARS-CoV-2 is analysed and it is shown that, to date, there is no detectable hallmark of recombination, which is a key assumption behind the application of phylogenetic inference methods. Expand

Expand
Emergence of SARS-CoV-2 through recombination and strong purifying selection
TLDR
Evidence of strong purifying selection around the receptor binding motif (RBM) in the spike and other genes among bat, pangolin, and human coronaviruses is shown, suggesting similar evolutionary constraints in different host species. Expand
Evidence of significant natural selection in the evolution of SARS-CoV-2 in bats, not humans
TLDR
The results suggest the non-human progenitor of SARS-CoV-2 was capable of human-human transmission as a consequence of its natural evolution in bats, and the role of positive selection and recombination in the Sarbecoviruses in horseshoe bats is contrasted. Expand
Natural selection in the evolution of SARS-CoV-2 in bats, not humans, created a highly capable human pathogen
TLDR
The results demonstrate the progenitor of SARS-CoV-2 was capable of near immediate human-human transmission as a consequence of its adaptive evolutionary history in bats, not humans. Expand
Isolation and characterization of a bat SARS-like coronavirus that uses the ACE2 receptor
TLDR
These results provide the strongest evidence to date that Chinese horseshoe bats are natural reservoirs of SARS-CoV, and that intermediate hosts may not be necessary for direct human infection by some bat SL-CoVs, and highlight the importance of pathogen-discovery programs targeting high-risk wildlife groups in emerging disease hotspots. Expand
Discovery of a rich gene pool of bat SARS-related coronaviruses provides new insights into the origin of SARS coronavirus
TLDR
It is hypothesized that the direct progenitor of SARS-CoV may have originated after sequential recombination events between the precursors of these SARSr-CoVs, and highlights the necessity of preparedness for future emergence of Sars-like diseases. Expand
Identifying SARS-CoV-2-related coronaviruses in Malayan pangolins
TLDR
The discovery of multiple lineages of pangolin coronavirus and their similarity to SARS-CoV-2 suggests that pangolins should be considered as possible hosts in the emergence of new coronaviruses and should be removed from wet markets to prevent zoonotic transmission. Expand
Isolation of SARS-CoV-2-related coronavirus from Malayan pangolins
TLDR
It is shown that a coronavirus isolated from a Malayan pangolin has 100%, 98.6%, 97.8% and 90.7% amino acid identity with SARS-CoV-2 in the E, M, N and S proteins, respectively, which suggests that the latter may have originated from a recombination event involving Sars-related coronaviruses from bats and pangolins. Expand
A SARS-like cluster of circulating bat coronaviruses shows potential for human emergence
TLDR
A potential risk of SARS-CoV re-emergence from viruses currently circulating in bat populations is suggested, and robust viral replication both in vitro and in vivo is demonstrated. Expand
