Unpacking the Origins of SARS-CoV-2: A Critical Examination

By Jonathan Latham, PhD

On February 1st, 2020, Dr. Anthony Fauci, the head of the US National Institute of Allergy and Infectious Diseases (NIAID), quietly gathered a select group of international virologists to assess a critical question: Was SARS-CoV-2, the virus that had recently emerged from Wuhan, engineered? Hidden behind this seemingly innocuous gathering was an urgent desire to understand the origins of a virus that would soon upend the world.

The Initial Conversations

Recent disclosures have revealed key emails from this meeting, showcasing initial thoughts within Fauci’s circle. Robert Garry, a virologist at Tulane University, expressed confusion over SARS-CoV-2’s natural emergence, noting, “I just can’t figure out how this gets accomplished in nature… it’s stunning.” Many participants, it seems, privately leaned towards the belief that the virus was lab-altered rather than naturally evolved.

Fast forward to August 2020, Francis Collins, the head of the NIH, approached Nobel laureate Howard Varmus for insights about a specific lab escape theory, referred to as the Mojiang Miner Passage theory. This theory was critical in scrutinizing the origins of SARS-CoV-2, suggesting a possible link to a group of miners in China who had contracted severe pneumonia-like symptoms in 2012.

The DEFUSE Project and the Collaborative Landscape

The DEFUSE project illustrates the controversial interplay of US and Chinese scientific efforts. Proposed funding aimed to take coronaviruses from China and augment their pathogenicity for research purposes. This situation accentuates how the scientific and political landscapes were, and still are, subtly intertwined, especially regarding the understanding of viral origins.

Despite initial discussions suggesting plausibility for a lab leak, notable figures within Fauci’s network publicly denounced this line of inquiry. They led efforts to dismiss and undermine speculation surrounding lab origins, thus propagating a narrative emphasizing a natural zoonotic origin.

Creating an Intellectually Poisoned Environment

The push to create an environment resistant to lab leak discussions has been evident, particularly on platforms like Twitter. Prominent virologists have gained notoriety for blocking anyone engaging in conversations surrounding lab leak theories, creating a suppressed discourse around critical scientific evaluations. Accounts dedicated to tracking such blockages, like BlockedByAVirologist, have proliferated, reflecting a defensive, almost coordinated stance among certain figures in the virology community.

This prioritization of reputational management over scientific openness begs a deeper inquiry into the implications of rigid adherence to a particular narrative—especially when such narratives may lack robust supporting evidence.

Scientific Reputation Management: A Closer Look

As the conversation on viral origins evolved, it became clear that many involved in the original Fauci circle were reticent to engage in meaningful discussions of the merits concerning various lab leak theories. One prominent paper that emerged early in this debate, “The proximal origin of SARS-CoV-2” (Andersen et al., 2020), categorically dismissed a lab leak scenario but lacked substantive scholarly rigor—an assertion supported by its “correspondence” format, as opposed to a full scientific paper.

Despite the paper’s premature conclusions, it has accrued over 4,453 citations, compared to the few citations garnered by alternative theories that entertain lab origins. Conversely, critiques of the MMP theory or similar hypotheses are often met with dismissive tactics that obscure substantive debate.

The Mojiang Miner Passage Theory: A Viable Explanation

At the heart of the MMP theory is the hypothesis that SARS-CoV-2 emerged from novel strains identified in miners who developed severe respiratory illness in 2012. Subsequent research indicated that these miners provided samples to the Wuhan Institute of Virology, where they were tested, hinting at the likelihood of lab activity with coronaviruses.

This theory underscores the lack of an identified intermediate host, a significant gap in the prevailing zoonotic narratives. The absence of an intermediary species adds credence to the proposal that these viruses could have evolved directly within infected miners before being transported to Wuhan.

Virological Discourses and Social Media Dynamics

In October 2021, Andrew Rambaut, a key player in the evolutionary virology sphere, publicly challenged the MMP theory on Twitter, emphasizing an “elevated rate of evolution” seen in chronically infected individuals. This tactical move not only revealed Rambaut’s standpoint but also mirrored a growing rift in the scientific community’s engagement with lab leak theories.

The significance of Rambaut’s critique lies in the lack of substantive evidence that follows. As discussions transitioned, his arguments often misrepresented the MMP theory, critiquing invalid points rather than addressing the legitimate scientific hypotheses put forth.

The Persistence of Misrepresentation

Rambaut’s critiques repeatedly fell into mischaracterizations, portraying the MMP theory as suggesting a direct descent from a specific virus—RaTG13—while overlooking the broader implications that a mosaic of genetic influences might be at play. This simplification not only misrepresents our views but also suggests a lack of engagement with the complexities inherent in viral evolution. Through extensive exchanges, it became increasingly evident that addressing straw men rather than direct arguments was a hallmark of this discourse.

The core of the MMP theory lies not merely in pinpointing a single viral ancestor but in hypothesizing how a human-adapted virus could emerge within an isolated population, subsequently leading to the global outbreak. This points back to important unresolved questions, such as why the Wuhan Institute was conducting research on such viruses and how mishaps could occur.

Examining the Responses

Despite numerous discussions, Rambaut and others failed to offer a substantive rebuttal to the MMP theory. The persistence of this narrative—whether stemming from institutional allegiance or personal reputation—highlights a concerning trend where empirical evaluations take a backseat to preconceived notions.

Rambaut’s transition between critiques further underscores a crucial element: the acknowledgment of evolving research in the realm of coronavirus origins. The discoveries of other closely-related bat coronaviruses reveal a complex evolutionary lattice, reminding us that our understanding of these viruses is continually in flux.

Remaining Questions and Scientific Ethics

This ongoing debate raises profound questions about the nature of scientific discourse and the ethical obligation of scientists to engage with all plausible hypotheses, regardless of prevailing narratives. The MMP theory, despite being maligned, presents a coherent framework that aligns with emerging evidence regarding SARS-CoV-2’s evolutionary trajectory.

The absence of decisive rebuffs from leading scientists like Rambaut points towards an unwillingness to engage meaningfully with competing theories, challenging the foundational ethos of scientific inquiry. Should scientists prioritize reputational safety over rigorous debate?

As scrutiny of the virus’s origins continues, the scientific community must reassess its approach to discourse surrounding lab leak theories versus natural origins, fostering an environment conducive to legitimate scientific progress rather than one mired in polarized views.

This deeper examination of scientific engagement, particularly concerning the Mojiang Miner Passage theory, may offer crucial insights into one of the most pressing questions of our time—the origins of SARS-CoV-2 and the implications for future viral research and public health endeavors.
