A theory is a question and I invite you to ask the question with me. If there is a clear reason why this cannot be true, or some part can’t be true, let me know and I will adjust. Send me your source please. I have been adjusting since the beginning based on the best sources I can find and I publish my current understanding for the purpose of being challenged. Thank you.

Being that this is a proposal of a twenty-plus-year phenomenon, it helps to review some medium-term urbanization and disease history for perspective.

Seeking Challenges

• Where has there been a major increase in human contact with living, breathing animals indoors? This would be the strongest possible challenge, especially if the animals were the ones most commonly identified as the culprit, bats or camels.
• The strongest challenge I have received is a description of unregulated industrial-scale animal food processing having increased in the same newly-modern countries where I am blaming human indoor economy. Valid challenge, but the animals are not live, indoor, or near the same scale as the humans working indoors.
• Another challenge has been the description of mutation through hybridization between human / non-human animal viruses. Okay, this is the currently accepted explanation, but what about mutation between viruses carried by two different humans? We have a new trend and humans are the ones newly living in the conditions where the virus spreads most on a massive scale: indoor, living, breathing humans.

Summary

Coronaviruses are spreading asymptomatically among a hugely-increased population of indoor humans, developing and evolving unnoticed for years, then chance mutations are causing outbreaks. SARS in 2002, MERS in 2012, and COVID-19 – all three related coronaviruses – are connected by the same progenitor: many many indoor humans sharing “exhaled breath sewage.”

Coronaviruses have passed among humans and various non-human animals for millennia. When coronaviruses caused illness, it was mostly mild illness, little more than an inconvenience to the hosts. The relationship was mostly commensalistic – that is until humans brought the coronaviruses indoors. The coronavirus population exploded in the fertile environment of air-conditioned urban centers and it was the historically well-cultivated commensalistic relationship with humans that enabled coronaviruses to be the first evolutionary beneficiaries of the new scale of man-made air-tight-indoor-air environment. The abrupt explosion of indoor space enabled by indoor economy – especially in high-density tropical areas – propelled life on its natural evolutionary path toward new disease-causing coronaviruses. “Viral gravity” is evolutionary gravity. Three new coronaviruses have emerged in under two decades, and indoor exhaled breath sharing is not just one primary spread vector. Indoor exhaled breath sharing is the evolutionary mechanism. Large-scale indoor exhaled breath sharing is the primordial soup, the origin, the creator, the genesis. Novel coronaviruses are the very first sprouts of new life in the Anthropocene.

Assumptions

Some of the following assumptions are difficult to quantify, but I believe so extreme as to be self-evident. Even if some specific assumptions are imperfect, the trend is clear.

• Three novel viruses in under twenty years is extremely abrupt by an evolutionary time period standard. It represents a new trend and requires something common to the three for explanation that is new.
• The number of humans spending time indoors has increased abruptly in the last three to five decades. The increase has been coincident with the emergence of new respiratory viruses. Increased number of humans indoors has led in time the emergence of the new viruses sufficiently to indicate it is a cause of virus evolution.
• Guangdong Province, China, Saudi Arabia, Jordan, Qatar, and Wuhan, China all use a lot of air conditioning, in contrast to how they interacted before recent development.
• Being relatively new, many of the origin cities’ buildings are built “air-tight” for central air conditioning instead of retro-fitted. Their buildings are not drafty or leaky.
• Evolutionary genetics has shown that zoonotic transmission is involved in virus evolution. However, this has not been definitively proven to be the final mutation into a disease-causing agent.
• Are coronaviruses known to evolve quickly? I believe they are. If they do evolve quickly, it would explain why coronaviruses are the first to take evolutionary advantage of the new collective virus reservoir of the human indoor economy.
• Evolutionary science can be subjective / statistical. Evolution relies on chance and succeeds with large numbers of chances for low-probability events to occur. A “macro-view” is more effective at identifying an evolutionary cause by identifying a large number of chances for a low-probability event to occur than is a “micro-view,” which attempts to find the actual single event itself. The critical “single evolutionary event” in these cases almost always occurred “somewhere in the world, anytime, anyplace” – and at least a month in the past with no trained observer present.
• Everything the virus does is consistent with thriving indoors. Our indoor economy has domesticated a virus like an invisible indoor pet that has now grown so numerous that is has turned against us and begun to make us sick.
• We will never find a “patient zero” for a virus that seems to float on the wind, but the virus exists, and the answer can be the clearly-observable shift in the wind itself.

The Theory: “Anthropogenic Coronavirus Evolution Theory”

In the early 21st century, a new type of virus emerged causing three distinct outbreaks between 2002 and 2020. Coronaviruses, which had passed among humans and non-human animals since the beginning of time, found new fertile development ground in urban skyscrapers built air-tight with central air conditioning that allowed exhaled breath sharing to go mainstream within humanity. Human indoor economy led to a new way of sharing “exhaled breath sewage,” which in turn led to new virus evolution.

Zoonotic leap among humans, bats, camels, palm civets, raccoon dogs, ferret badgers, pangolins, and domestic cats in markets and other various locations of human / non-human animal interaction was originally theorized as the primary evolutionary requirement and origin of the viruses. Matching the virus to infected animals along with genetic markers suggested that animals were the primary reservoir. However, it was later determined that human breath sharing on a large scale in dense, newly-developed, warm-weather cities with skyscrapers built air-tight for central air conditioning was the primary reservoir and original source for all affected species in these outbreaks. Humans indoors first developed viruses with mostly asymptomatic spread hyper-enabled by large air-tight buildings. Humans passed viruses to animals, some of whom got sick, but not until humans got sick did humans finally look in the animals, find matching viruses, and point to the animals as the source.

However, as the novel coronaviruses repeatedly appeared and developed into a trend, humans noticed that the small change in human-animal live indoor contact was insufficient to explain multiple similar occurrences of indoor live human respiratory viruses. Zoonotic transmission therefore lost favor as an explanation for evolutionary development of novel coronaviruses.

The Virus Reservoir and Evolutionary Mutation

The fact that the three new viruses are all suspected to have an excellent ability to circulate among humans without causing disease indicates that asymptomatic spread among indoor humans is the reservoir. The evolutionary mutation is that the virus mutates from a benign virus to a disease-causing virus. The new scale of the indoor humans reservoir is providing the large number of chance events required for evolution.

We have three new viruses. The viruses are related. There has to be a new type of reservoir to explain it. The animals have not changed a lot. The human coronavirus reservoir has changed a lot! The critical mutations are among millions of human-human transfers and multiplication.

Naming Note

• The alternate names for the viruses of “EBSRS-CoV-1,” “EBSRS-CoV-2,” and “EBSRS-CoV-3” are used to illustrate the point and unify the viruses. The names refer to SARS-CoV-1, MERS-CoV, and SARS-CoV-2 respectively.

2019: Exhaled Breath Sewage Respiratory Syndrome Coronavirus 3

• AKA EBSRS-CoV-3 (formerly SARS-CoV-2)
• First identified in Wuhan, China.
• Wuhan China lies near 31 degrees north latitude and has more than 3.5 months per year with average daily high temperature above 27°C.
• Wuhan China ballooned in population from 3.5 million in 1990 to over 8 million in 2020, massive new urbanization and indoor economy.
• EBSRS-CoV-3 is known to transmit well through aerosols asymptomatically among humans, consistent with many transmission events for evolutionary purposes, especially in enclosed rooms.
• Zoonotic transmission not yet conclusively verified despite global effort.
• Cruise ships are a known vector, with their closed ventilation systems.
• There are wet markets in Wuhan, but the virus seemed to “spread everywhere quickly out of nowhere,” with no clear connection to animal contact.

2012: Exhaled Breath Sewage Respiratory Syndrome Coronavirus 2

• AKA EBSRS-CoV-2 (formerly MERS-CoV)
• First identified in Saudi Arabia. Later determined that it possibly circulated in Jordan as well. https://www.cdc.gov/coronavirus/mers/about/index.html
• Saudi Arabia is a petro-state (cheap energy for air conditioning) that has experienced a population explosion since 1980. Now 80% of its inhabitants live in 10 major urban centers, mostly in the southwest of Saudi Arabia, well within the tropics.
• Qatar was another potential origin, a very hot petro-state country.
• EBSRS-CoV-2 is also thought to pass asymptomatically among humans.
• Known to infect camels and bats. Transmission from camels to humans has been observed, but no “patient zero” identified in relation to camel contact.

2002: Exhaled Breath Sewage Respiratory Syndrome Coronavirus 1

• AKA EBSRS-CoV-1 (formerly SARS-CoV-1)
• Outbreak started in Guangdong Province, China.
• Guangdong Province lies in latitude very near the Tropic of Cancer.
• Just north of Hong Kong, Guangdong Province is home to two of the top four Chinese cities by GDP. Guangdong Province’s GDP is larger than Spain’s GDP, and would be the 13th country in the world by GDP. Lots of humans working indoors. Indoor economy.
• This first outbreak appears to have been more closely and reliably connected to markets and wild animals than the later two outbreaks. However, the origin is inconclusive due to CCP blocking of WHO officials for several weeks or months after the emergence of the outbreak.

Question: were the first cases in “air conditioning months” in all three outbreaks?

Question: does polluted air contribute?

Exhaled Breath Sewage Coronavirus Evolution Theory Explains the Following Better than the Zoonotic Transmission Theory

• Why both EBSRS-CoV 2 and 3 spread so well asymptomatically among humans. Asymptomatic spread was required for virus evolution months or even years prior to identification as a disease-causing agent. People often reference the idea that a disease spreads more successfully with a low mortality rate because the host is alive to spread. Asymptomatic spread is zero mortality, which is commensalistic, which is the ideal relationship for evolving.
• Why all three of the viruses originated in relatively warm, newly-developed cities with exploding indoor economy partially enabled by air conditioning.
• Why three new respiratory diseases have emerged in just 20 years coincident with urban population explosion in warm regions with air-tight buildings and air conditioning.
• Why the three new coronaviruses, that supposedly came from zoonotic transmission from different animals, are so closely related to each other. We have a very specific trend, there is probably a very specific, related cause.
• Why EBSRS-CoV-3, the most transmissible of the three new viruses, is so mild. It gradually increased in severity as it evolved quickly until concentrating in a large city, Wuhan, China, which may or may not have been the true origin.
• This theory is not completely at odds with zoonotic leap being an evolutionary aid to the virus development.
• Maybe there are multiple, even hundreds, thousands, or millions of significant virus mutation events. Maybe the world has been widely infected with a mostly benign, asymptomatic form of the virus that teeters on the edge of a disease-causing mutation that occurs relatively often. Maybe any pandemic involving a brand new virus acts differently from a long-time established, maturely evolved virus. Maybe a new virus relies more on mutation and evolution continuously and therefore acts differently in predictable as well as inherently unpredictable ways. We are not dealing with a turtle virus, established in its ways after having survived millions of years of evolutionary change with its simple “head in the shell” trick. We are dealing with a young rabbit being chased by a puppy darting in every direction not knowing where to go and therefore going everywhere changing frantically at every random turn.
• Maybe the vitamin D deficiency correlation with COVID-19 fatality does not mean vitamin D deficiency is a comorbidity but rather a second, related symptom that is correlated with being indoors and having been exposed to a higher infectious dose of the virus.

Zoonotic Transmission Virus Evolution Theory Explains the Following Better

Update: somebody help out here because trying to describe zoonotic transmission evolution theory makes it a joke. It is absolutely laughable we humans are trying to point to animals as a source.

But I will try, here we go:

• The zoonotic transmission theory says that a virus circulates among an animal population as a reservoir until it mutates by chance and gains the ability to infect humans. Once it infects humans, it causes disease.

Or

• Two similar viruses, one human and one non-human animal, infect the same cell in a host, hybridize by replicating together, and henceforth infect humans causing disease.

And…

It makes perfect sense so far, but I’m at a loss attempting to seriously continue:

• Human-animal contact has increased on an unprecedented scale along with mass global urbanization. The viruses have started in poor countries with under-regulated food processing industries. The new scale of these markets yields enough increased zoonotic transfer to produce three new viruses in 20 years.
• OK, but live human-animal contact? Indoors?
• Are there new indoor markets? Why airborne? Why the seemingly lightest fastest aerosol-borne viruses possible?
• Humans have gotten sick with a virus that spreads primarily indoors. If we want to say this came from animals, we need to see live camels and live bats breathing indoors, enclosed with humans. This virus did not crawl from dead bat meat into somebody’s mouth and then suddenly in just a few virus generations spread tiny virus wings and infect the world of humans, airborne, indoors all at once. Did flying fish get stranded on land, sprout lungs in a generation, and lo! mammals? No. Did some ancient monkey-sailors get caught at sea, sprout a blowhole on top of their head and start swimming, lo! whales? No. We need an intermediate environment. Unless you can show me some large-scale enclosed indoor breathing animal markets, you’re debunked. I can show you plenty of indoor breathing human virus markets: they are called cubicles, call centers, housing complexes, public transit, skyscrapers – modern human cities and also clearly recognizable as Every. Single. Confirmed. Serious. COVID-19 outbreak.
  • Note: Don’t suddenly tell me hoards of people are hanging out in bat caves. Show me a modern widespread market-driven caveman-bat-batman movement of at least 10 million people and we’ll talk. It still would not explain the camels anyway. Does the Arabian Peninsula have tons of closed-air camel garages for the wealthy now? They have never heard of Ferrari’s? The camel shit is whisked off the floor by robots or what? Would the camels even put up with that? Would humans hang out for hours in such a garage? I’m not buying it.
• The only reason wet markets and China’s under-regulated food processing industry exist at the scale at which these species transfers are more likely is the world’s mass urbanization.
• Genetic history marker studies? Do the zoonotic transmission claims based on genetics hold up to the scrutiny that they have been influenced by pervasive confirmation bias from the beginning? We lack conclusive cause-effect evidence to support critical genetic assumptions.
• Hybridization by a single host being infected with two coronavirsuses, which hybridize as they multiply together within the cells? Okay, but three times in 20 years? Roll snake eyes three times in a row, go. I’ll be checking your dice.
• Does zoonotic leap novel coronavirus evolution stand up against the idea that it still could play a secondary role in the evolutionary process? Does zoonotic leap fit in as only 10% of the process instead of 90%? I think it fits just fine in 10% of the solution, second-place to the obvious.
• The supporting evidence for the zoonotic transmission origin theory is scant relative to the monumental efforts at collecting it. I feel justified being unsatisfied.
• This theory appears to be an outdated assumption that has survived only by momentum of past convention. “Of course, humans get new viruses from animals,” – that is until they give new viruses to animals.
• Observed recent changes in human-animal contact is not new enough or extreme enough to explain a major new evolutionary trend of three new viruses. This is especially true with respect to indoor human-animal contact. It is more especially true also when compared with the recent explosion in indoor human-human breath sharing contact.

Confirmation Bias Toward Zoonotic Transfer Evolution

• There is a strong – bordering on fanatically blinding – confirmation bias for the zoonotic leap virus evolution theory among the scientific community. A single piece of evidence for zoonotic transmission or discovery of similar virus in non-human animals is often regarded as the “case closed smoking gun.” This prevents further research and discovery of the true cause.
• There is a natural aversion to identify humans as a “virus reservoir.”
• “Viruses are nature. Viruses have to come from nature. We are not nature, we are people!” Recognize that? Pretty familiar. That is people being ridiculous.
• It is so widely ingrained into our psyche that, “If a virus were there, we would be sick,” that we ignore asymptomatic spread as the potential evolutionary origin of new viruses.
• No definitive patient zero has been identified in any of the three new coronavirus outbreaks. Connection to markets and animals was inevitable due to the strength of the confirmation bias.

Humans Indoors as a Spread Vector Versus Humans Indoors as the Evolutionary Mechanism

• “Transmission vector” has been poorly separated from “evolutionary cause.” Air-tight buildings as a new transmission vector could indeed easily explain why zoonotic-leap-generated respiratory viruses are now suddenly a worse problem. Air-tight buildings would spread new zoonotic leap viruses fast. True. Of course. However, this easy explanation prevents people from recognizing that asymptomatic transmission is essentially equal to an evolutionary cause. Asymptomatic transmission can enable evolution, not just virus spread after evolution.
• If indoor exhaled breath sewage evolution theory is correct, one might expect COVID-19 to be seasonal and peak in the summer. However, this confuses spread vector with evolutionary mechanism. Still, if air conditioning is enabling evolution, opening the windows should be moved up the list of COVID-19 prevention measures.

If True, Exhaled Breath Sewage Evolution Theory Would Suggest

• That though reducing contact with animals might possibly slow evolution, new coronavirus respiratory viruses will continue to emerge with or without animal contact as long as humans spend a lot of time in buildings breathing each other’s exhaled breath sewage.
• The global response to COVID-19 will (eventually!) include sanitation of indoor air. Sanitizing indoor air will not only slow the spread of COVID-19, it will slow the development of future respiratory viruses.
• Sanitation of indoor air should be the primary prevention measure against COVID-19 because it would also eliminate the evolutionary source of new disease-causing coronaviruses.

Air Conditioning Versus Heating – What’s the Difference?

Long story short, I cannot make an argument that there is a big difference between air conditioning and heating. Both air conditioning and heating lead to people spending time indoors sharing exhaled breath. The only difference with air conditioning is the recent increase in human-hours spent breathing indoors as a result of increased population in places that use air conditioning. Air conditioning enables large indoor economy.

• baseboard heat would not sanitize air
• The origin cities may not be rich enough for widespread air conditioning and I do not have that data to support.
• Is this valid: When a building is heated, heating sanitizes the air from viruses much better than cooling the air does? In a heater, the temperature spikes up in the furnace heat exchanger above where viral RNA survives well – what about baseboard heating though? In an air conditioner, the temperature spikes down when cooled, failing to break down viral RNA. Therefore, heated air-tight buildings do not act as a collective virus reservoir like air-conditioned buildings do. Is this true? Is this true enough? Questions on this one: types of heating, types of air re-circulation, actual amount of AC in origin cities, difficult to get this data. Is air conditioning simply providing the sheer indoor human numbers required and is independent of the type of indoor climate control?
• Too many details to make a separation between air conditioning and heating. Thanks to all the people who challenged me on this. This theory stands without it and is stronger without the weak link, which was never necessary.

Some Optimism – An Existing Prevention Measure Becomes the Solution

• Can entire cities open the windows in the summer and “sweat the curve flat”? This confuses evolutionary origin with spread vector, but still connected.
• A global standard of indoor air sanitation could completely eliminate the evolutionary virus reservoir “primordial soup” and stop the recent trend (three in just two decades) of novel coronaviruses. An air sanitation standard would certainly benefit in the fight against COVID-19.
• N95 air conditioner filters anybody?
