Ralph Baric described synthetic viruses with artificial fingerprints as early as 2006, designed to deliberately deceive about their origin
A 2006 publication by Dr. Ralph Baric – the University of North Carolina virologist widely regarded as a leading developer of chimeric coronavirus genomes and in silico virus assembly techniques – openly describes how synthetic viral genomics could be used to digitally create viruses containing misleading genetic “fingerprints” designed to mislead researchers about a false geographic or evolutionary origin.
It would turn out that the SARS-CoV-2 pathogen of the covid-19 pandemic exhibits precisely the three characteristic spike features whose incorporation into chimeric SARS-related coronaviruses Baric and his colleagues had explicitly proposed in the 2018 DARPA/EcoHealth-DEFUSE proposal: a furin cleavage site (PRRA) at the S1/S2 junction site, targeted, human-optimized mutations throughout the receptor-binding region (including the critical residue Q498), and substitution by two prolines (V1060P/L1061P) to stabilize the spike protein in its prefusion conformation.
Also in 2018, Baric was granted US patent 9,884,895 B2 for “Methods and Compositions for Chimeric Coronavirus Spike Proteins”, which claims proprietary techniques for modular domain exchange and seamless synthetic computer assembly of coronavirus spikes.
Twelve years earlier, in the very same 2006 publication that first laid out the theoretical framework for such artificially created viruses, Baric had already described how computer-generated genomes could be specifically designed to serve as “scapegoats” and carry misleading sequence signatures that would steer any investigation into their true origin in the wrong direction.
The 2006 publication, titled Synthetic Viral Genomics: Risks and Benefits for Science and Society, appeared as part of a broader review of biodefense and synthetic biology, examining the future risks posed by synthetic genomics, reverse genetics, and recombinant virus development.
In one of the most striking passages of the paper, Baric explained that synthetic viral genomes could be deliberately engineered on the computer (in silico) to resemble the supposedly naturally circulating strains from a particular region or time period, thereby creating what he termed a “scapegoat” sequence signature.
Baric wrote:
“Synthetic virus genomes can be designed to be identical to specific virus strains that circulated in a particular location in any given year. This powerful technique offers bioterrorists the opportunity to create a ‘scapegoat’ by leaving a genetic signature that will steer investigations in the wrong direction to track down the true perpetrators of the crime.”
The statement is significant because it explicitly describes how the tracing of genomic lineages – one of the most important methods for determining the geographic origin and evolutionary history of viruses – could theoretically be manipulated through synthetic genome design.
This means that, according to Baric’s own description, a synthetically composed virus could potentially be designed to appear on the computer screen as if it naturally originated from a different country, outbreak cluster, or evolutionary lineage.
Even now, years after the covid pandemic, leading scientific journals claim that no one has succeeded in “solving the mystery of where a virus came from that is estimated to have killed more than 20 million people and cost the global economy up to $16 trillion by the end of 2022”.
Could the “scapegoat” mechanism described by Ralph Baric in 2006 – the targeted development of synthetic viruses with misleading genetic fingerprints, designed to steer investigations into the origin in the wrong direction – explain why the true origin of SARS-CoV-2 remains unclear despite years of intensive international research?
The publication described the development of viral genomes that supposedly mimic naturally circulating strains.
At the beginning of the publication, Baric described how synthetic genomics and seamless genome assembly techniques could be used to reconstruct viruses directly from published sequence databases.
He wrote:
“Every viral genome could be synthetically reconstructed from sequence databases, provided the sequence is correct.”
Baric also explained that computer-aided assembly systems made it possible to systematically construct large viral genomes while removing evidence of the assembly process from the final sequence.
The paper described “no see’m” assembly approaches in which artificially created restriction sites used during cloning could later be removed from the finished genome.
The publication states:
“No-see’m sites can be used to insert foreign genes into viral, eukaryotic, or microbial genomes or vectors while removing all traces of the restriction sites used in recombinant DNA manipulation.”
This means that the constructed assembly markers used in in silico construction would not necessarily remain visible in the final genome sequence.
Baric explained that synthetic genomics offers possibilities that go beyond traditional recombinant DNA techniques, as synthetic genomes can be assembled without retaining the obvious cloning signatures that typically remain with older molecular engineering methods.
The publication stated:
“Recombinant viruses produced using classical recombinant DNA techniques carry the signature of the parent virus used in the process, as well as new restriction sites that were inserted into the genome during the cloning process. In contrast, synthetic viral genomes can be designed to be identical to exact virus strains circulating in a specific location in any given year.”
This section immediately preceded the “scapegoat” discussion surrounding the publication.
Synthetic DNAs offered “unprecedented opportunities” for malicious purposes.
The article initially presented synthetic genomics as a system capable of constructing viral genomes with deliberately chosen sequence features.
Baric wrote:
“Synthetic DNAs and systematic assembly approaches also offer unprecedented opportunities to construct genomes of any sequence, while simultaneously opening up new possibilities for malicious purposes.”
This statement is significant because it openly describes synthetic genomics as a technology that offers unprecedented opportunities to engineer viral genomes with tailored sequence features.
Viral genome sequences as geographic “fingerprints”
Before introducing the article’s “scapegoat” concept, Baric first explained that viral genome sequences act as forensic identifiers that can be used to determine the likely geographic origin.
The document states:
“Genome sequences represent fingerprints that allow for a geographical mapping of the likely origin of a particular virus.”
According to the study, this means that researchers use sequence signatures and genome comparisons to deduce where a virus likely originated and its evolutionary relationship to other strains.
Baric then contrasted traditional approaches of recombinant DNA with newer systems of synthetic genomics.
The document states:
“Recombinant viruses produced using classical recombinant DNA techniques carry the signature of the parent virus used, as well as new restriction sites that were incorporated into the genome during the cloning process.”
This means that older recombinant methods could leave detectable genomic traces of manipulation in the laboratory, including restriction site signatures and identifiable traces of the parental genome scaffold.
The paper then compared this to synthetic genomics approaches.
Baric wrote:
“In contrast, synthetic viral genomes can be designed to be identical to exact virus strains circulating in a specific location in any given year.”
This means that synthetic assembly systems could theoretically be used to construct viral genomes specifically designed to resemble alleged naturally circulating strains from a selected region, outbreak, or evolutionary lineage.
The “scapegoat” option & scenarios of misattribution
Baric then described what he called the “scapegoat” option.
The article stated:
“This powerful technology offers the bioterrorist a ‘scapegoat’ option; it leaves a sequence signature that steers efforts to track down the true perpetrators of the crime in the wrong direction.”
This means that Baric explicitly described how synthetic viral genomes could theoretically be constructed with intentionally misleading sequence signatures in order to redirect forensic attribution to another source.
The article then further exaggerated the scenario.
Baric wrote:
“Even better: This approach could be used to sow distrust and/or trigger an open war between nations.”
The statement is noteworthy because it openly discusses the geopolitical implications of a manipulated genomic mapping.
Baric then presented a hypothetical scenario involving the foot-and-mouth disease virus (FMDV), outlining how a synthetic outbreak strain could potentially be designed to resemble viruses associated with certain foreign regions.
He wrote:
“A simple example could be the use of the picornavirus foot-and-mouth virus, which is not found on the North American continent but is endemic in Africa, Asia, the Middle East and South America.”
Baric explained that geographically distinct FMDV strains contain unique sequence signatures that allow researchers to determine the likely geographic origin.
The publication stated:
“Geographically distinct FMDV strains contain unique sequence signatures that allow for easy determination of origin.”
Baric then directly described the scenario of a synthetic assignment:
“A North American outbreak of an infectious ‘synthetic’ FMDV virus containing signature sequences reminiscent of strains found in select Middle Eastern or Asian countries considered by the US government to be terrorist states would further inflame escalating tensions and could provide a welcome pretext for military retaliation.”
This means that Baric openly discussed the possibility that synthetic genomics could theoretically be used to create genetically misleading outbreak strains that could trigger geopolitical consequences or enable false attribution.
The article also stated that synthetic reconstruction methods could potentially make it possible to assemble infectious viral genomes without needing direct access to physical virus stocks.
Baric wrote:
“It is conceivable that a bioterrorist could order genome segments from various synthesis facilities in different countries worldwide and then assemble an infectious genome without ever having access to the virus.”
The article described the possibilities and implications of synthetic genomics and reverse genetics.
Throughout the article, Baric repeatedly described how advances in synthetic biology, reverse genetics, and genome assembly technologies created unprecedented opportunities for the design and modification of viruses.
The text at work stated:
“There are tools to modify genomes simultaneously in such a way as to increase virulence, immunogenicity, transmissibility, host range and pathogenesis.”
The paper continued:
“Synthetic biology expands all the possibilities offered by recombinant DNA research. The main advantages of synthetic genomics over classical recombinant DNA approaches are speed and mutagenesis capacity, which enables cost-effective design of the entire genome.”
The article covered the following topics in particular:
- the synthetic reconstruction of viruses from sequence databases,
- the assembly of full-length coronavirus genomes,
- the production of recombinant SARS-CoV,
- seamless “no see’m” genome assembly systems,
- the synthetic reconstruction of spike glycoproteins
- as well as the ability to create viruses that intentionally carry misleading genomic signatures.
“Humanization” of zoonotic viruses
Baric’s article also discussed the low cost and high speed of synthetic construction systems.
Baric wrote:
“The project costs would likely be less than $50,000, including synthesis, extraction and distribution.”
The article then discussed further technical possibilities related to the adaptation of zoonotic viruses.
According to the article:
“Another possibility could be to improve replication efficiency by optimizing for human codon use, which is particularly useful in the ‘humanization’ of zoonotic viruses….…”
This means that the work openly discussed the modification of viruses of animal origin to improve their compatibility with human cell systems.
It is striking that the SARS-CoV-2 virus genome, which was handed over to us by Chinese cooperation partners Baric at the end of 2019, exhibited precisely the human-adapted spike features that Baric had discussed in 2006: an insertion of a furin cleavage site and mutations of the receptor-binding domain optimized for binding to human ACE2 – exactly what he and his colleagues had explicitly proposed incorporating into chimeric SARS-related coronaviruses as part of the 2018 DARPA/EcoHealth DEFUSE proposal.
In the 2006 publication, Baric then emphasized how these synthetic systems could assemble a genome “within weeks”.
The publication states:
“In both examples, standard recombinant DNA approaches would be difficult and laborious, whereas synthetically produced genomes could be easily manufactured within weeks.”
Conclusion
Ralph Baric’s 2006 article provided a detailed blueprint for how to digitally construct a virus that could never be traced back to its true creator.
He described how viruses are reconstructed directly from sequence databases, seamlessly assembled using “no see’m” techniques that erase all traces in the lab, and deliberately given misleading “scapegoat” genome signatures to steer any investigation into the origin in the wrong direction.
In 2018, the very year that Baric and his colleagues proposed, as part of the DARPA/EcoHealth-DEFUSE project, to insert the furin cleavage site, human-optimized RBD mutations, and 2P stabilization into chimeric coronaviruses, Baric also received US patent 9,884,895 B2 – a patent claiming proprietary methods for modular domain exchange and seamless synthetic assembly of coronavirus spikes.
These three manipulated features first appeared together in SARS-CoV-2.
But despite years of international investigations, the origin of the virus, which killed millions of people and cost the global economy up to 16 trillion dollars, remains officially unclear.
Now the question arises: Was the ongoing “mystery” surrounding the origin of SARS-CoV-2 the predictable result of precisely the scapegoat mechanism that Baric described in 2006?
