SJA #23 - 12 November 2018 - HADers and The Three Pillars





AIDS/HIV Denial
Sooooo, next up on the skepdocket is AIDS/HIV Denialism, or, more popular, HIV/AIDS denial, or HAD. And that means we get to call the deniers HADers! Yay for fun with acronyms!

HAD can take a number of forms, like denying that AIDS (Acquired Immune Deficiency Syndrome) even exists, that HIV (the Human Immunodeficiency Virus) exists, denying that HIV causes AIDS, that HIV tests are reliable, and that antiretroviral medicines help AIDS patients. Really, this shit is all over the place.

First, AIDS doesn’t exist, wtf? For this bit of whackadoodle, the claim is that AIDS isn’t a disease or a syndrome, but a catch-all for a bunch of similar looking conditions. They say that what we call AIDS is just the result of malnutrition and recreational drug use taking its toll on the body, or even that it’s caused by the medicines used to treat AIDS. How would the antiretroviral drugs used to treat AIDS cause AIDS before the patient was taking the medicine? Don’t ask! We’re in denial territory, where reality isn’t real but money aplenty to be made!

So, yeah, AIDS does exist. It was first documented in the early 1980s when outbreaks of certain very rare conditions started cropping up. These diseases were only associated with severely compromised immune systems and these patients were adults without a history of immune disorders. The CDC organized a task force to investigate these outbreaks. At first the illness was referred to by several different names related to, for example, the various rare illnesses that occurred in the victims, or the common characteristics of the victims.

The press, of course, came up with an incredibly helpful method for referring to the disease that made things better for everyone and didn’t cause any problems at all: GRID, the Gay-Related Immune Deficiency.

And there we have one of the big reasons why HAD has been so popular for so long. People have come a long way in the last thirty years. In 1981, when they were still calling it GRID, gay folks weren’t simply fighting for their lives; gay marriage wasn’t even a distant dream. You could lose your job for being gay, your landlord could evict you, your family could (and probably would) disown you, you’d face hostility and discrimination in public, you’d very likely face violence in public, and when you did you wouldn’t dare call the police because they might well decide to go ahead and finish the job of beating the gay out of you.

So AIDS was associated strongly with the gay community from the very first, and the public for a long time assumed that having AIDS meant you were gay and that being gay meant you would get AIDS. And, of course, the fundagelicals leapt all over it, claiming AIDS was god’s punishment on the homosexuals.

To their credit, the CDC quickly realized that AIDS is not intrinsically related to being gay, and had coined the term AIDS by the summer of 1982, a year after the syndrome was discovered. The revelation that the epidemic wasn’t confined to the gay community didn’t calm people’s fears, obviously. It helped turn things into a different kind of panic, and birthed a lot of conspiracy theories, fear, and hatred directed at the gay community. As recently as 2013, televangelist and human skin factory Pat Robertson was claiming that gay people were using sharpened rings to cut people during handshakes so as to spread AIDS.

In 1982, that sort of thinking was everywhere, especially since the disease was spreading without apparent cause and popping up in major cities without showing up in intervening locations. Perhaps you’ve heard of “Patient Zero”? That actually comes from the epidemiological tracking as they tried to understand the disease, how it spread and developed, and how they could treat it. They asked for, and got, a surprising amount of information from infected gay men about their previous sexual partners. The coding for this information would identify partners by where they were from, and a person from out of town would be marked with an “O”.

And there was one particular out of towner… he was a flight attendant for an airline with a knack for picking men up in the cities he flew in and out of. And that’s one of the ways the disease spread so quickly, and why it showed up in major airport hubs first.

The Reagan White House didn’t help any of what was going on, not with treating the disease, nor quelling the public’s fears about this unknown plague, nor with the hatred being aimed at gay people. The White House Press Secretary spent a lot of time cracking jokes with the press corp at the gay community’s expense. It’s rather horrific.

Anyway, we now know that AIDS is caused by the HIV, and that HIV is a mutated form of a related virus, SIV, the Simian Immunodeficiency Virus. I ask you to imagine how much fun it was for the black community when it was discovered that a sexually transmitted disease had its origin in African chimpanzees. As one who was alive and marginally aware when that little tidbit was discovered, yes, people were incredibly racist about it. Just so you know, it comes from the habit of some poverty-stricken people of killing and eating chimpanzees, aka “bushmeat”.

At any rate, the disease spread out of Africa thanks to the Congo achieving independence in 1960. When Belgium left, they didn’t leave any experienced administrators behind and the international community reached out for help. A large number of Haitians answered the call and it appears some caught the disease at that time, taking it back to Haiti with them. This explains one of the CDC’s early attempted names for AIDS, the 4H disease: for Heroin users, Homosexuals, Hemophiliacs, and Haitians, the four most common victims of the disease. We now know that the disease is transmitted by exchange of bodily fluids, such as during sex or blood transfusion.

The significant number of Haitians who helped the Congo transition to independence brought the illness back to Haiti with them in the mid 1960s. It then appears to have been transferred to the mainland US in the late 60s or early 70s, when it established a foothold. It of course takes time for the disease to progress to the point where the immune system has become so weak that other, opportunistic diseases can infect the patient, hence why AIDS didn’t start appearing until 1981.

So we’ve already got a lot of homophobia and a healthy current of racism, can we get any other bigotries in there? Of course we can! Anti Semitism! Plenty of conspiracy theories running around out there about the origins of AIDS being a Jewish plot to something something white people something something black people something something gay people.

But despite the various conspiracy theories and despite the wide variety of nonsense the denialists throw out there, the overwhelming majority of HAD came from homophobia, at least for a long time. HAD appears to have declined somewhat, becoming a weird culty thing powered not only by homophobia and a soupçon of racism, but also with a healthy fear of any large group of experts, like doctors and pharmacists and other… well, let’s be honest, that’s where some anti-semitism comes into the equation. Conspiracy theorists love to hate on the Jews.

But there’s a weird little strain of HAD that you might not see coming. It’s chiropractors. Now, I’ll be ranting in detail about chiropractic once we get to the Cs, but let’s leave it for now that the core of chiropractic is the belief that all illness, all illness, is caused by so-called subluxations, or malformations of the spinal column. These subluxations prevent God’s Energy from up in Heaven being transmitted to all your organs by the spinal column (Heaven’s above us, right? And the energy comes in through your head and goes to your body via the spine, because logic).

To be fair, some chiropractors mix the core chiropractic bullshit with other forms of complete bullshit, and some even try to practice something approaching medicine. However, the fact remains that chiropractic is built on a foundation of manure, and that it includes the belief that the Germ Theory of Disease is wrong, and that all doctors are either ignorant quacks or paid shills.

Your life has to be pretty goddamn sad if you’re on the same side as neonazis, the KKK, and Pat Robertson and you look like the weird one because “No no no, it’s not about the Jews, it’s just that your spine is kinda bendy so God’s Magic Energy is having trouble getting to your pancreas!”

I want to go ahead and throw a lot of shade at religion here, too. One highly effective method for preventing the spread of HIV is wearing condoms, and a large number of very well funded and very politically active churches are against condoms because baby Jesus is allergic to latex or some shit. The Catholic Church naturally bears a huge chunk of blame, because they’ve always been against any kind of birth control or family planning, thus making them just a little bit genocidal because people are dying by the millions from this shit in countries where the Catholic Church has massive influence.

However, the Proddies aren’t getting off scot-free. Being in favor of birth control and abortion used to be a protestant thing, a way of distinguishing yourself from the hated Kathalicks, but that changed with the birth of the so-called Moral Majority. In response to blacks and gays and Jews suddenly becoming “people”, the fundagelicals decided to freak the fuck out and launch a moral crusade. They wanted to get the Catholics on their side, so they adopted birth control and abortion as pet issues. Little did they know that those would rapidly consume most of their energy… and not get the Catholics on their side.

Still, they’re highly energized and well funded, and they like to evangelize and try to get laws passed. We’ve been seeing the fruits of their efforts here in the US, of course, but they also do this shit overseas. Uganda, for example, has passed a number of evangelical-backed anti-gay laws. The fundagelicals are pushing as hard as the Catholics to make birth control and abortion illegal wherever they can, and their disproportionate influence in the US government increases their power, because they then wield the twin cudgels of foreign aid and military intervention to push foreign governments in the direction they want.

Have I mentioned lately how much I hate religion? Because I really hate religion.

In Sub-Saharan Africa alone, the HIV infection rate stands at roughly 8.8 percent of the population, and that rate is increasing. Tens of millions of people are dying of an illness that does not need to spread.

That’s not strictly a consequence of HIV/AIDS Denialism, but HADers have good friends in the church and the Thuglican party. Hell, some of them are prominent members of both. And the fact that HAD is wrapped up in homophobia and racism just lets it get more deeply embedded, running under the surface.

The Three Pillars
The three pillars of white supremacy, as outlined by Andrea Smith, are slavery/capitalism (the interaction of white supremacy with Africa), genocide/colonialism (white supremacy in the Americas), and orientalism/war (white supremacy in Asia).

Before we continue, some controversy. Andrea Smith is, as best I can tell, fairly well respected as an activist for women generally and women of color in particular as well as an academic working on related topics. Unfortunately, she has maintained that she is Cherokee since at least 1991 (and said that her identification as such was part of the reason she was denied tenure at the University of Michigan in 2008). However, she has no connection with any tribe and a tribal genealogist has said that she hired him twice and he found no evidence of Cherokee ancestry either time.

Many Cherokee scholars and activists have criticized or condemned her for this, saying her actions hurt the Cherokee people and Native Americans more broadly. Her response has been to continue to claim Cherokee ancestry and identity, rejecting the need to be officially affiliated with a tribe.

So, yeah, on that front, Andrea Smith is a douche. On a side note, this offers the chance to reflect on Elizabeth Warren’s related claims and position. As I understand it, Warren once identified as a Native American on a form in law school, thanks to a long-standing family belief that one of her ancestors was Cherokee. That appears to be the only way in which her story is similar to Smith’s, because she never otherwise claimed Cherokee heritage, never identified as Cherokee, and never used it to advance her career. Instead, Harvard claimed it on her behalf to defend itself against accusations that it didn’t have professors of color.

When she went on to enter politics, Warren continued to not claim Cherokee ancestry, heritage, or identity. She didn’t run on it, didn’t include it in campaign materials or ads. It wasn’t until Trump started talking politics that, once again, other people dug it up to use it for their own purposes. She has continued to maintain, and a DNA test appears to support her, that she has native ancestry, but has never claimed tribal affiliation or identity.

Anyway, Smith’s three pillars. Smith edited an anthology published in 2006, “The Color of Violence: The INCITE! Anthology”. One of the articles was her own work, “Heteropatriarchy and the Three Pillars of White Supremacy: Rethinking Women of Color Organizing”. It’s a six page article that, implicitly and explicitly, criticizes the “oppression olympics” thinking that crops in activism and organizing. The article doesn’t mention intersectionality, but looking over it, seems to respond to and criticize it. I also see a lot of bell hooks in the article, though I confess I’ve not read hooks. In short, what I see here is like that surprisingly old criticism: there is much here that is good and original; however, what is original isn’t good and what is good isn’t original. (that criticism dates back at least to 1781!) So let’s look at what Smith says here (remember, it’s only a six page article, link in the thingy, so you can easily go read it yourself).

After her introduction criticizing “oppression olympics” for stymying organizing, Smith says that white supremacy rests on three pillars, three logics, three methods of interacting with non-white populations.

  • slavery/capitalism
  • genocide/colonialism
  • orientalism/war

She then follows that with a discussion of the implications for organizing, talk about heteropatriarchy and US Empire, and her conclusion.

To start, I don’t disagree with her three categories. When Europeans exploded onto the rest of the world, they encountered different regions, with different human populations, with different cultures and technologies, and European actions against to those populations differed accordingly. However, and this critique may be unfair, their actions weren’t so easily disentangled as she seems to posit.

This critique may be unfair because this is a very brief article by Smith, not a full academic treatment. Capitalism can’t be easily linked only to slavery, genocide wasn’t limited to the Americas, Orientalism didn’t only manifest in war, and she seems to ignore Australia entirely.

White supremacy and, yes, heteropatriarchy, manifested themselves differently on the different continents not because they embodied different logics, but because the same logic (us = good, you = bad) was responding to different situations. White Supremacist Capitalist Heteropatriarchal Imperialism (WhiSCHI) operated via near absolute genocide in the Americas and not in Asia nor Africa not because Europeans didn’t want to enslave and profit from Native American bodies, but because European diseases repeatedly decimated native populations, beginning and enabling that genocide. By contrast, African and Asian populations had resistances to those same diseases and Europeans simply couldn’t commit those genocides.

Likewise, WhiSCHI manifested differently in Asia than it did in Africa. Africa presented an entirely different landscape of diseases and crops that Europeans had difficulty penetrating, Asia had cultures, traditions and civilizations that Europeans recognized and respected. In Africa, Europeans kidnapped individuals into slavery because they had so much difficulty controlling the landscape and surviving the climate. In Asia, they dominated politically through warfare because the path of Asian civilization had led to hierarchies that could be exploited in that fashion, which path African civilizations hadn’t taken.

In all three cases, European imperialists transformed the native population into an exotic other to be dominated, exploited, and killed as necessary. They were to be brought into the existing hierarchy as less than Europeans, which led to the invention both of whiteness and the other races/racisms that WhiSCHI exploited. Capitalism encouraged this through profit motive, racism through emotional means. Genocide, war, and slavery were all tools through which the logic of WhiSCHI operated.

European invaders didn’t develop a different perspective on Native Americans completely independent from their attitudes toward Asians. Instead, they held a single viewpoint, that they and their civilization were the peak of all humanity, and that others were lesser beings there to be used. Africans and Native Americans thus became “unintelligent savages” who were “incapable of civilization”; Africans were distinguished from Native Americans as “violent brutes” to justify holding them violently in bondage, as a way to control them. By contrast, Native Americans were denigrated as being unforgivably weak so as to justify not holding them in bondage, and instead merely driving them to extinction and taking their land.

Asian civilization couldn’t be ignored, so it had to be worked around, and the result was that WhiSCHI developed orientalism, a confusing morass of conflicting beliefs that at once praise Asian people for the unignorable facts of their long history, their historical developments, their art, culture, and science, their basic humanity while at the same time rendering them inferior, barbarian, effeminate, weak, and deserving of European domination.

Australian natives were treated in their own way, another combination of the attacks on other peoples. They were enslaved and subjected to genocide. They were kidnapped, owned, murdered, raped, “re-educated”, had their lands stolen… Their experience was different from all the others, but built on the same foundation. Perhaps the fact that their situation contains elements of both African and American colonization, preventing them from fitting neatly into her three pillars, is why Smith excluded them from her analysis. Or perhaps, like many people, she just forgot them.

In any event, no, it’s not different logics, different pillars. It’s one logic; the fascist logic of hierarchy, of believing that some people are possessed of some “essence” that renders them superior, and that this applies not only to individuals, but to whole populations and “races”. So long as they were confined to Europe, European fascist hierarchism confined itself to identifying different European populations as superior or inferior, different European individuals. When, through historical accident, Europeans burst out and began attacking the rest of the world, that same fascist hierarchical thinking was applied, repeatedly and in different directions, to the rest of the world.

And I want to stress that that fascist hierarchical thinking is not and has never been limited to Europe. That form of thinking has always been part of humanity. Wherever humans had the good luck to discover writing and wherever we have the good luck for that writing to survive to the present, we discover the same variations in human thought. All humans and all human populations have fascist tendencies, with some feeling more strongly than others the emotions that drive toward fascism.

Had historical and geographical accident driving things differently, a Chinese global empire would have exercised the same logic, intersectional thinking would instead be operating to undermine Han Supremacist Capitalist Heteropatriarchal Imperialism. Perhaps the Queen of Sheba would have implemented a heteromatriarchy.

Like I said, I’m seeing a lot in this article that owes a great deal to intersectional thinking and perhaps bell hooks. I’m not excessively impressed by Smith’s analysis, and I have to roll my eyes at her apparently complete lack of self-awareness in writing about white people appropriating native identity during the section on genocide and native erasure. She builds on marxist critique, on intersectional critique, on the work of actual women of color, but doesn’t appear to add anything new.

On the other hand, maybe my perspective is too limited, too distant, too ill-informed. I could easily be biased in that I’m an outsider who really only knows about the best, strongest, most useful portions of critical race theory, of intersectionality that are filtering out to the broader population. Smith’s article is more than a decade old, and I have the advantage of not being down in the weeds with the real intellectuals. I could easily be treating Smith unfairly.

Anywho, links in the thingy; lemme know what you think about Smith and about my reading of her work.

Evolution Myths Part II

So I already covered a number of myths about evolution. Now I'll cover some more. They won't complete the entire list of erroneous things people believe, but maybe it'll flesh out our understanding both of evolution and of the weird crap people believe about it.

Of Course There Are Monkeys
The denialist loves to ask, "If we evolved from monkeys, why are there still monkeys?" Part of this is to deliberately set up the notion that evolution declares an equivalence between humans and monkeys to drive a wedge between the audience and evolution. However, this myth at its core misunderstands speciation.

Some species lives in a region A. It spreads, it grows in number, it explores the limits of its environment, then spills over into a second region B. Over time, geology happens and regions A and B are separated, isolating the two groups. Geology continues to happen, climate slowly changes, the environment changes. Perhaps region A becomes wetter and turns into a marshland while region B becomes more arid and turns into a grassy area with some stands of trees. The population of our species lives and adapts to each of these new climates. They mutate, they change. Their physical forms change and less obvious biological changes occur within. Eventually the two have changed enough that they can no longer interbreed. You now have two species where before you had one. At no point could you look at either and say, "Ah, this is clearly different to what came before." The change is always very slow, very gradual, and there will never be a clear dividing line.

Regions A and B don't even need to change for speciation1 to occur. Simple separation will be enough. Random changes will still accumulate in both groups and eventually genetic drift (also known as allelic drift) will build up to the point where the two groups will be chemically infertile. The geographical separation doesn't need to be drastic; it doesn't have to be something like a mountain chain springing up or an island separating from the mainland; simple distance will suffice. A ring species is one that has a long enough range that divergence has occurred between the individuals at either end. Subspecies A can interbreed with B, which can mate with C, which can make babies with D, which can totally start a family with E, but A and E are far enough apart that they're they're no longer interfertile. That's speciation in progress.

Another key item to note is that speciation doesn't mean that you start with species A and all of a sudden you have species B branching off of it. You begin with species A, then species A will split into subspecies B and subspecies C, still similar enough to interbreed but separated by geography2. They will continue to diverge until you have two separate species. They will still be obviously related, like the many species of cats alive today, and they'll also be clearly related to the ancestor species (with which they may or may not be able to interbreed; like ring species, but with time instead of space).

As for humans, we share a common ancestor with the two species of chimp, the common chimp and the bonobo. We share a more distant ancestor with the other great apes, the gorillas, and even more distant with the orangutan. None of those ancestors were the same species as any extant species.

The question above "why are there still monkeys" is like asking, "If you came from your grandparents, why are your grandparents still alive?", and what they're really asking is "If you came from your grandparents, why do you have cousins?"

Evolution Is Not a Tautology
Denialists like to claim that evolution doesn't contain any information. Natural selection chooses the fittest to survive, right? But how do we know which are the fittest? They're the ones who survive! It's circular! Like a donut!

Fitness has an actual definition. It's the relative propagation of a trait in a population. It's actually a mathematical definition. If the relative abundance of a trait increases from one generation to the next, then fitness is greater than one. If it decreases, it's less than one. For a single organism, it's defined as the relative contribution by the individual to the gene pool for that particular trait. Fitness is a multigenerational consideration and has to do not merely with how well an organism survives, but how it thrives and contributes to the survival and alteration of its species.

Evolution Does Not Predict Chimeras

Behold, the mighty crocoduck! That particular mythical creature is the favorite of Kirk Cameron, erstwhile child actor cum fundamentalist rabble-rouser. The denialist believes that speciation means mermaids and catdogs. That between species A and its successor species B, you'll find something that is literally half of species A stitched to species B. Evolution does NOT predict this. It definitely doesn't predict a transitional form that's two halves of modern species. This is a gross misunderstanding of the nature of transitional forms.

Look at red and yellow on the rainbow. In between you'll find orange. Zoom in some more and you'll find a color between red and orange. Zoom in further and you'll find another color, neither red nor orange, nor red-orange, but red-red-orange. Zoom in further and you'll find something that's redredorange-redorange in between the two. You'll never find a discrete line dividing any two colors. you'll also never find a color that's a bit of red stapled to a bit of orange.

As it is with the colors, so it is with evolution. When A changes to B, it does so very slowly, very gradually. Tiny, incremental changes accumulate. A lizard gives birth to a dizard that gives birth to a bizard that gives birth to a bzard that gives birth to a bzrd that gives birth to a burd that gives birth to a bird, and it all takes millions of years. You never see something with the head of lizard and the tail of a bird. A transitional form is something like this:


That's an archaeopteryx. Discovered just two years after Darwin published On the Origin of Species it was a stunning confirmation of exactly what his theory called for: a transitional form between reptiles and birds. You can see that it has feathers, wings, and scaled hindlimbs like both bird and lizard. However, it still has a toothy snout like a reptile, along with a long, reptilian tail among those feathers. You can also see differentiated fingers on its fore-limbs, which aren't yet wings; birds will lose those fingers to create a fully functional wing. The archaeopteryx is an actual example of a transitional form. That's why evolutionary theory took the world by storm; it accounted for all the facts and made incredible and accurate predictions like this. That's what a theory does.

The chimera is not the prediction of evolution. It's the prediction of religion and myth, a magically created creature with no antecedents in the fossil record and no natural way of appearing.


Humans Are Still Evolving
The last myth I'll cover here, and one I haven't put on the TVTropes page yet, is that humans are somehow above evolution.

Lots of people, even people who are fully willing to accept that evolution occurs, that the earth is 4.5 billion years old, that the universe is 13.7 billion years old, and that humans actually aren't the be-all and end-all purpose of creation in a universe so vast that we don't even count as lint... they just don't accept that we're evolving. I believe it's related to the notion that we're rational animals (not really), smart enough to avoid stuff like that (we're really not), and that we've seized control of our destiny thanks to our intelligence (absolutely false. It is to laugh).

We're totally evolving. As I said last time, each of us is born with dozens of mutations. We can't know where we'll end up. Hopefully we'll end up without some of awful crap I mentioned last time. Who knows, maybe we're turning into this guy.




Well, that's it for now. There are tons of myths out there about evolution, but these have been some of the most popular. Maybe later I'll talk about global warming denialism.



1 - The term for the formation of a new species.

2 - Geography is too specific a term. I should be saying that their habitats become separated. If one group spends all its time on the ground and the other spends all its time in the tree tops, then they can still be isolated enough to speciate.

Evolution Myths

There are those who deny that evolution happens. Or they admit that it does happen, but only a little bit. Or, fine, it happens, but not to people. Or maybe it happened to people in the past, but we're too smart for that now. There are degrees of evolution denialism, just as there are degrees to religious fundamentalism. People who don't like evolution have their silly little beliefs; these are they, and why they're wrong.

Some of you may notice a lot of overlap between this page and the Useful Notes -- Evolution page over at TVTropes. That's because I wrote a significant chunk of that, and I make no bones about it. Other people have also contributed to it, not least they made it not look like ass. They also tidied up the verbiage and corrected quite a bit of my biology. Anyway, on to destroying some myths!


Evolution Has No Goal
Evolution is a stochastic (non-deterministic) process. It's not building toward anything in particular; hell, it's not building toward anything at all; hell, it's barely even building. Evolution moves around randomly, sampling the landscape of potential forms and behaviors. It fills every niche. In so doing, it creates new niches, then it fills them, creating new niches to fill! Leave it to a nineteenth century poet to say it:

Great fleas have little fleas upon their backs to bite ’em,
And little fleas have lesser fleas, and so ad infinitum.
And the great fleas themselves, in turn, have greater fleas to go on;
While these again have greater still, and greater still, and so on.

De Morgan: A Budget of Paradoxes, p. 3771

Evolution is sort of like a gas; it expands to fill the space it's in. But it's also simultaneously creating that space. It's a weird, squirmy, umpty-dimensional gas. Wibbly-wobbly, timey-wimey. But it doesn't have a goal. It doesn't pick winners.

The most tragic consequence of this myth is what it did with the notion of the superior race, which was around long before Darwin developed his theory. The Nazis were the most famous purveyors of this myth, but it was widespread among many groups in many nations until the Nazis demonstrated how utterly horrific it is when taken to its natural conclusion. This myth, and its natural end, are both used by opponents of evolution as an argument against it, but evolution doesn't predict this.

A human, a tree, a sea slug, and an E. Coli bacterium are all highly evolved organisms, flourishing in their environments and striving to pass on their genes. None is superior to the others, none more highly evolved. A cheetah is particularly well adapted to running down fast prey, but it will never outfight a bear, which will never be as deft with its paws as a raccoon, who can't swim with the fishes, who don't know how to do math. We are each of us what we are, with nearly the same 3.5 billion years of evolutionary history behind us. And a tree won't have nukes, anger and lower back problems2.

Evolution: More than Mere Chance
Evolution is an unguided, stochastic process with randomness at its heart, but randomness isn't the only thing their is. Natural selection is an incredibly powerful tool that immediately weeds out negative changes and strongly favors positive.

Imagine 1000 people flipping coins. If they flip every five seconds, how long before they come up all heads? On average, 1,697,702,940,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years. That's 10^284 times longer than the universe has been around.

Now, imagine that they all flip and keep the heads. Everyone with tails flips again, and they keep the heads. Anyone who has tails flips a third time, and so one. How long before we have all heads? 500 + 250 + 125 + 62 + 32 + 15 + 8 + 4 + 2 + 1 + 1 = 1000 heads in 11 flips, on average, for a total of 55 seconds. Flipping randomly hoping to get a particular outcome is unrealistic, but once you throw in the power of selection, you take away the sting.

Whether life on our planet is as dramatic as my coin toss example depends on the power of your imagination.

Evolution Promises Very Little
Evolution doesn't promise us the best of all possible worlds. It promises us the bare minimum to get where we are right now. That's why we have lower back problems. And wisdom teeth that get impacted. And a tiny piece of intestine that likes to crawl up its own ass and die. And then there's the pregnancy thing. And the pelvis thing. And our knees. And we're blind and deaf. And our children are completely fucking helpless for about a decade and a half. And have I mentioned that we can't run very fast? And we're no good in the cold. Or the hot. Or the water. And man alive the desert will kill us so fast.

And that's just what's wrong with human beings. Evolution isn't magic. It'll find solutions for all of our problems, but it'll take a few thousand generations, and it'll find new problems along the way.

Evolution is About How Life Changes
It isn't how life began. The origin of life is called abiogenesis. ('a' - not, 'bio' - life, 'genesis' beginning. 'abiogenesis' - how life came from non-life). Evolution is about how life, once it's here, has developed and changed. Descent with modification and natural selection is the theory that explains the observed process of change in life already extant.

Abiogenesis is a hella interesting field that lies in the borderland between geology, chemistry, and biology. So far we know that it took at most about half a billion years for life to appear on Earth, however it formed, because we have fossils of bacteria nearly four billion years old. We can know something about the conditions, and geology and chemistry and physics are all working together to piece together those conditions and give us a clearer picture. Then biochem steps in and works out how you get from those to how life can appear. It's a wonderfully fascinating endeavor.

But it's not evolution.

I'll be honest; we might not ever know exactly how life evolved on Earth. If we're phenomenally lucky, then perhaps we'll get to observe it happening on another planet, or maybe we'll make incredible breakthroughs in theoretical chemistry and physics and develop a fantastic model of the early Earth. I don't know; ignorance actually is an acceptable position to take in science. "I don't know" is always the starting position, and a possible finish line. It's never a satisfying position, but it's acceptable in the face of little or no evidence.

But abiogenesis and the current state of that field of study have no bearing on evolution. Evolution is so well established that trying to overturn it is like trying to overturn gravity. When I say we have tons of evidence for it, I mean literal tons. We're talking about actual rocks here.



We'll cover more myths in part II.


1 - The line originally appeared in a poem by Jonathan Swift, who was mocking the idea of self-similarity in fractals. What I quoted is from a mathemetician later in the century who was also discussing fractal self-similarity. But it works.

2 - Those three lines I lifted right from the TVTropes page. I wrote the original, but it's been edited since, and I have to give props to user memememememe for fleshing it out.
