Godless Heroes

Once upon a time, in a far away desert, a priest came to visit a girl working at her poor family’s farm. He asked her, “Do you like going to the Temple?”

“Oh, yes. I look forward to it every week.” She smiled as she fed an impatient nanny goat and her kids. “The Temple is beautiful and clean and quiet.”

The priest was pleased by her answer. “Do you study the scriptures?”

“Oh, yes. My whole life.” Still smiling, she drew water from the well and tipped it out for the thirsty peppers. “The scriptures give me a lot to think about.”

He was impressed. “Do you obey God’s Laws?”

The girl paused with an egg halfway to her basket. She gave the priest her full attention for the first time. “Am I in trouble?”

The priest gave a little placating gesture and a smile. “No, no. I’ve spoken with your family. They tell me you’re old enough and ready to take your first Temple vows.”

Basket and egg were forgotten. “What kind of vows? To become a priest and look after people?”

“Of course not. Priests are all men. Your Temple vows are simply promises to God that you will obey His Laws and his priests.” He noticed her disgust. “What’s wrong? Aren’t you faithful?”

After a gaping pause, she laughed as though tickled. “Of course not. Worshipers are all mad!”

Funny thing about atheists: We enjoy ritual and song and participating in acts of community as much as anyone does. Many atheists even have a ‘spiritual’ side – an affinity for the unknown and the uncertain that leads many of us to pursue science as a path to personal enlightenment as well as a career. We seem drawn to fantasy in fiction for similar reasons.

There’s a fair amount of sci-fi in which humans discover that their deities are actually aliens, or humans insert themselves into alien pantheons in order to control their behavior. There’s certainly an abundance of sci-fi that borrows heavily from mythology for its major plot points. And while there’s still a lot of work to be done in sci-fi (and speculative fiction as a whole) with regard to race and issues of gender and sexuality, at least pantheons and priests don’t seem to dominate every other space opera on offer.

Fantasy is a different beast. There are exceptions, but it seems that the default is to tie magic with religion in fantasy worldbuilding. Not that mages are all priests in disguise, although that’s sometimes the case, but rather in worlds where magic is a fact of life, often deities are also real. Consequences of this include an unfortunate dependence upon deus ex machina to rescue untenable plots, and a disappointing shortage of compelling secular lead characters in fantasy.

At the very least, there’s a vast and virtually pristine wilderness left to explore in fantasy. There are thousands of unwritten books about brainy little girls who can think and act as well as they can heal and hurl levinbolts.

Low-tech Antiseptics, part 2

The importance of keeping wounds clean is something we take for granted now, and we have all the benefits of science and industrial production to provide us with cheap and effective antiseptics. These posts examine some reasonable options for the doctors and healers of a realistic fantasy world to have at hand.

Part 1 discussed salt and sodium bicarbonate.


Your brave character uncorks that vodka bottle with his teeth and pours it over his wound. Problem solved? Check the label first.

Surgical-grade ethanol runs from 60-90% alcohol by volume. In drinking terms, that’s 120-180 proof. Most of the stuff in the liquor cabinet tops out at 100 proof — though you can get brandies that are 120 proof and the infamous Everclear is available in 151 and 190 proof.

Simple distillation dates from the first century AD, in Europe, and methods gradually improved during the Renaissance and really took off in the 19th century. So the good news is that it’s not unreasonable for a fantasy world to know how to distill alcohol from fermented mash.

The bad news is that simple distillation (from the most primitive forms up to more complex but still low-tech moonshine stills) will not get you pure enough alcohol to be really effective as an antiseptic. For that, you need a reflux column. (For further information, Google reflex column stills and their use by backyard fuel-alcohol producers.)

Whether this is feasible in your fantasy world (the metallurgy skills, the safety issues) is for you to determine. But once you have that worked out and your healers have access to high-proof alcohol, they can be sterilizing wounds and mixing cocktails at the same time, right? Hopefully the producers didn’t opt for fermenting cheaper stuff like sawdust instead of grain (wood alcohol = methanol = blindness) and hopefully they didn’t build their still out of soft, easy-to-work lead

What about rubbing alcohol? That would be isopropyl alcohol, and it’s a good antiseptic but I haven’t been able to find a way to produce it without industrial chemistry. If you find something, I’d be curious to know.


All of the above — salt, natron, and alcohol — are by no means as effective as modern antibiotics or even the stronger antiseptics like iodine or phenol-based compounds. How you use them in a story is your call, but they are not magic bullets that will realistically bring a character back from death’s door.

If you’re looking for a semi-plausible magic bullet, though: terpenes.

Terpenes are a major component of resin and turpentine (distilled resin) — both important compounds with long, pre-industrial histories. Turpentine itself was used medicinally (and still is, actually) for jobs which included wound-cleansing. (Also de-worming, though I can’t imagine drinking the stuff.) Another natural, low-tech antiseptic containing terpenes is tea tree oil.

Terpenes are compounds synthesized by trees, mostly (some bugs too), particularly conifers (cedar, firs, junipers, etc.). If one wanted a “magic bullet” healing compound in one’s fantasy world, an exotic local tree producing a terpene-packed resin could fit the bill. It can be as scarce and hard to find as the story requires, or common and widely used. Maybe it requires processing — distilling, fermenting, mixing with something else.


So: four ways to help your characters survive their adventures without invoking magic, deities, or doing something as nonsensical as boiling wine. (I wrote a little rant that started all this. It seems to have attracted some eyeballs.)

That Shy, Elusive Rape Particle

Note: This article originally appeared on Starship Reckless

[Re-posted modified EvoPsycho Bingo Card -- click on image for bigger version]

One of the unlovely things that has been happening in Anglophone SF/F (in line with resurgent religious fundamentalism and erosion of democratic structures in the First World, as well as economic insecurity that always prompts “back to the kitchen” social politics) is the resurrection of unapologetic – nay, triumphant – misogyny beyond the already low bar in the genre. The churners of both grittygrotty “epic” fantasy and post/cyberpunk dystopias are trying to pass rape-rife pornkitsch as daring works that swim against the tide of rampant feminism and its shrill demands.

When people explain why such works are problematic, their authors first employ the standard “Me Tarzan You Ape” dodges: mothers/wives get trotted out to vouch for their progressiveness, hysteria and censorship get mentioned. Then they get really serious: as artists of vision and integrity, they cannot but depict women solely as toilet receptacles because 1) that has been the “historical reality” across cultures and eras and 2) men have rape genes and/or rape brain modules that arose from natural selection to ensure that dominant males spread their mighty seed as widely as possible. Are we cognitively impaired functionally illiterate feminazis daring to deny (ominous pause) SCIENCE?!

Now, it’s one thing to like cocoa puffs. It’s another to insist they are either nutritional powerhouses or haute cuisine. If the hacks who write this stuff were to say “Yeah, I write wet fantasies for guys who live in their parents’ basement. I get off doing it, it pays the bills and it has given me a fan base that can drool along with me,” I’d have nothing to say against it, except to advise people above the emotional age of seven not to buy the bilge. However, when they try to argue that their stained wads are deeply philosophical, subversive literature validated by scientific “evidence”, it’s time to point out that they’re talking through their lower digestive opening. Others have done the cleaning service for the argument-from-history. Here I will deal with the argument-from-science.

It’s funny how often “science” gets brandished as a goad or magic wand to maintain the status quo – or bolster sloppy thinking and confirmation biases. When women were barred from higher education, “science” was invoked to declare that their small brains would overheat and intellectual stress would shrivel their truly useful organs, their wombs. In our times, pop evopsychos (many of them failed SF authors turned “futurists”) intone that “recent studies prove” that the natural and/or ideal human social configuration is a hybrid of a baboon troop and fifties US suburbia. However, if we followed “natural” paradigms we would not recognize paternity, have multiple sex partners, practice extensive abortion and infanticide and have powerful female alliances that determine the status of our offspring.

I must acquaint Tarzanists with the no-longer-news that there are no rape genes, rape hormones or rape brain modules. Anyone who says this has been “scientifically proved” has obviously got his science from FOX News or knuckledraggers like Kanazawa (who is an economist, by the way, and would not recognize real biological evidence if it bit him on the gonads). Here’s a variation of the 1986 Seville Statement that sums up what I will briefly outline further on. It goes without saying that most of what follows is shorthand and also not GenSci 101.

It is scientifically incorrect to say that:
1. we have inherited a tendency to rape from our animal ancestors;
2. rape is genetically programmed into our nature;
3. in the course of our evolution there has been a positive selection for rape;
4. humans brains are wired for rape;
5. rape is caused by instinct.

Let’s get rid of the tired gene chestnut first. As I’ve discussed elsewhere at length, genes do not determine brain wiring or complex behavior (as always in biology, there are a few exceptions: most are major decisions in embryo/neurogenesis with very large outcomes). Experiments that purported to find direct links between genes and higher behavior were invariably done in mice (animals that differ decisively from humans) and the sweeping conclusions of such studies have always had to be ratcheted down or discarded altogether, although in lower-ranking journals than the original effusions.

Then we have hormones and the “male/female brain dichotomy” pushed by neo-Freudians like Baron-Cohen. They even posit a neat-o split whereby too much “masculinizing” during brain genesis leads to autism, too much “feminizing” to schizophrenia. Following eons-old dichotomies, people who theorize thusly shoehorn the two into the left and right brain compartments respectively, assigning a gender to each: females “empathize”, males “systematize” – until it comes to those intuitive leaps that make for paradigm-changing scientists or other geniuses, whereby these oh-so-radical theorists neatly reverse the tables and both creativity and schizophrenia get shifted to the masculine side of the equation.

Now although hormones play critical roles in all our functions, it so happens that the cholesterol-based ones that become estrogen, testosterone, etc are two among several hundred that affect us. What is most important is not the absolute amount of a hormone, but its ratios to others and to body weight, as well as the sensitivity of receptors to it. People generally do not behave aberrantly if they don’t have the “right” amount of a sex hormone (which varies significantly from person to person), but if there is a sudden large change to their homeostasis – whether this is crash menopause from ovariectomy, post-partum depression or heavy doses of anabolic steroids for body building.

Furthermore, as is the case with gene-behavior correlation, much work on hormones has been done in mice. When similar work is done with primates (such as testosterone or estrogen injections at various points during fetal or postnatal development), the hormones have essentially no effect on behavior. Conversely, very young human babies lack gender-specific responses before their parents start to socialize them. As well, primates show widely different “cultures” within each species in terms of gender behavior, including care of infants by high-status males. It looks increasingly like “sex” hormones do not wire rigid femininity or masculinity, and they most certainly don’t wire propensity to rape; instead, they seem to prime individuals to adopt the habits of their surrounding culture – a far more adaptive configuration than the popsci model of “women from Venus, men from Mars.”

So on to brain modularity, today’s phrenology. While it is true that there are some localized brain functions (the processing of language being a prominent example), most brain functions are diffuse, the higher executive ones particularly so – and each brain is wired slightly differently, dependent on the myriad details of its context across time and place. Last but not least, our brains are plastic (otherwise we would not form new memories, nor be able to acquire new functions), though the windows of flexibility differ across scales and in space and time.

The concept of brain modularity comes partly from the enormously overused and almost entirely incorrect equivalence of the human brain to a computer. Another problem lies in the definition of a module, which varies widely and as a result is prone to abuse by people who get their knowledge of science from new-age libertarian tracts. There is essentially zero evidence of the “strong” version of brain modules, and modular organization at the level of genes, cells or organ compartments does not guarantee a modular behavioral outcome. But even if we take it at face value, it is clear that rape does not adhere to the criteria of either the “weak” (Fodor) or “strong” version (Carruthers) for such an entity: it does not fulfill the requirements of domain specificity, fast processing, fixed neural architecture, mandatoriness or central inaccessibility.

In the behavioral domain, rape is not an adaptive feature: most of it is non-reproductive, visited upon pre-pubescent girls, post-menopausal women and other men. Moreover, rape does not belong to the instinctive “can’t help myself” reflexes grouped under the Four Fs. Rape does not occur spontaneously: it is usually planned with meticulous preparation and it requires concentration and focus to initiate and complete. So rape has nothing to do with reproductive maxima for “alpha males” (who don’t exist biologically in humans) – but it may have to do with the revenge of aggrieved men who consider access to women an automatic right.

What is undeniable is that humans are extremely social and bend themselves to fit context norms. This ties to Arendt’s banality of evil and Niemöller’s trenchant observations about solidarity – and to the outcomes of Milgram and Zimbardo’s notorious experiments which have been multiply mirrored in real history, with the events in the Abu Ghraib prison prominent among them. So if rape is tolerated or used as a method for compliance, it is no surprise that it is a prominent weapon in the arsenal of keeping women “in their place” and also no surprise that its apologists aspire to give it the status of indisputably hardwired instinct.

Given the steep power asymmetry between the genders ever since the dominance of agriculture led to women losing mobility, gathering skills and control over pregnancies, it is not hard to see rape as the cultural artifact that it is. It’s not a sexual response; it’s a blunt assertion of rank in contexts where dominance is a major metric: traditional patriarchal families, whether monogamous or polygynous; religions and cults (most of which are extended patriarchal families); armies and prisons; tribal vendettas and initiations.

So if gratuitous depictions of graphic rape excite a writer, that is their prerogative. If they get paid for it, bully for them. But it doesn’t make their work “edgy” literature; it remains cheap titillation that attempts to cloak arrant failures of talent, imagination and just plain scholarship. Insofar as such work has combined sex and violence porn as its foundation, it should be classified accordingly. Mythologies, including core religious texts, show rape in all its variations: there is nothing novel or subversive about contemporary exudations. In my opinion, nobody needs to write yet another hack work that “interrogates” misogyny by positing rape and inherent, immutable female inferiority as natural givens – particularly not white Anglo men who lead comfortable lives that lack any knowledge to justify such a narrative. The fact that people with such views are over-represented in SF/F is toxic for the genre.

Low-tech Antiseptics, part 1

These posts brought to you by the recurrence of the search term “boiling wine” bringing people to my little rant on the use of same on wounds in GRRM’s A Song of Ice and Fire series.

Magical healing aside, basic sanitation is the one thing that will most increase your characters’ chances of survival when they’re injured. Stitches are helpful. So are herbs. Splints are important for broken bones. But if that cut gets infected, abscesses, and gangrene sets in, all the willow bark tea in the world isn’t going to save you.

In real-world history, the importance of keeping wounds clean was not fully realized until only a few hundred years ago. Why your fantasy world’s physicians know they need to do this is up to you. I’m going to look at how to do it in a world without industrialized chemical analysis and synthesis.


Gargling saltwater for a sore throat and old recipes for toothpaste made of salt and baking soda (more on that later) work because salt does kill microbes when it’s concentrated enough. This is why pickling and salting work as food preservatives.

Pickled characters

Brine recipes call for anywhere from a half cup to a cup of salt per gallon of water, which would be 3 – 6% salt by volume. Seawater tends to be more like 3 – 4%.

Depending on where your characters are, seawater could be easy to get and a reasonable thing to wash a wound with — if the seawater has been filtered and hopefully boiled as well. It does contain microbes that are acclimated to salty water, after all.

Brine prepared from salt and boiled water is a viable option if your characters have access to economically priced salt. Or maybe it’s a rare and expensive way to treat wounds, reserved only for those who can afford it. Either way, I recommend Mark Kurlansky’s Salt as an excellent overview of salt production over the course of history.

Character jerky

Given a supply of fairly pure salt, why not just pack the wound with salt? Yes, that’s been done in the past. Especially with abscesses, it seems. The packing needs to be changed a few times a day, and after the salt’s done its job the wound will need to be closed by whatever method and given a chance to heal. You don’t actually want to make jerky out of your character.

Sodium bicarbonate

You know it better as baking soda. Combined with salt and a little water, baking soda makes for a nasty-tasting toothpaste but it’ll kill those germs and even bleach your teeth a little.

Naturally occurring bicarbonate is one of several compounds found in natron, which the Egyptians used for cleaning, an antiseptic, and to preserve mummies. Natron is mined from natural deposits, which can be found in a variety of places — not just deserts. Perhaps this would be a viable industry for your fantasy kingdom on top of its medical uses.

Baking soda mouthwash recipes range up to 25% concentration but tend to fall more around a teaspoon per half pint of water which would be… 4%? As with salt above, your healers could use either a brine to wash wounds or pack the wound directly with natron — bearing in mind that we don’t want to mummify the characters just yet. Natron is a drying agent, which means it draws out moisture from the tissues. This makes the tissues less hospitable to bacteria… and life in general.

Stay tuned for the more accurate use of alcohol (not by boiling wine, for crying out loud) and an antiseptic wild card.

Our Epic Prehistory

Neanderthal reconstruction by Kennis & Kennis/Photograph by Joe McNally

I love me some Tolkien. But for everything that The Lord of the Rings has done for the fantasy genre, it has also been so overwhelmingly influential and compelling that it is has spawned entire franchises set in worlds imitating Middle Earth, and has stifled the genre’s creativity. Unless otherwise specified, fantasy is assumed to be set in a medieval European setting and populated by humans, elves, dwarves, orcs, and halflings. Dwarves are always assumed to be great craftsmen and miners who live underground in halls of stone and favor geometric patterns in their art and writing. Elves always inhabit verdant forests, are skilled in magic and craft fine weapons and armor with leaf shapes and magical properties. Orcs are brutish and primitive and wear spiky black armor and wield spiky black weapons. I am hardly the first person to make these observations, and in recent years there has finally been some real progress in emerging from the shadow of Tolkien, but we have a long way to go. I would like to propose just one alternative that not only bucks some of the trends that Tolkien started, but also has some science at its heart.

In most fantasy settings, there are several intelligent species coexisting in the same world, each with a distinctive culture and appearance. In our modern world of course, there are humans of cultures and appearances that vary beyond anything seen in most fantasy, but there are no other similarly advanced intelligent species for us to interact with. This was not always the case. In the course of human evolution, we coexisted with several other species of human, including Neanderthals, Homo floresiensis, and the recently discovered Denisova hominin.

Hominid evolution is a complicated and rapidly changing field, and my summary here will likely make archaeologists and anthropologists cringe, but I hope it will also kindle some ideas for speculative fiction writers looking for something a bit different.

I will start with homo erectus, a species that originated in Africa around 1.8 million years ago and spread across much of Asia into India, China, and Indonesia. Homo erectus was clearly quite successful, and there is evidence that they used stone hand axes and fire, and were probably one of the first hunter-gatherer societies. They stood about as high as modern humans, but their skeletons are more robust and they were more heavily muscled. It is not clear when homo erectus went extinct, but they may have lasted in isolated pockets until relatively recently, and may have interacted or even interbred with early homo sapiens. In fact, Homo floresiensis, which lived in Indonesia as recently as 12,000 years ago, shows some similarities to homo erectus, although homo floresiensis is smaller.

Model of Homo erectus from Museum of Archaeology, Herne, Germany

The most famous hominid that coexisted with humans is the Neanderthal. Neanderthal remains have been discovered throughout Europe and as far east as the Altai mountains. They lived from 600,000 years ago until about 25,000 years ago. Despite the stereotype of Neanderthals as dumb brutes, evidence suggests that they may have been just as intelligent as humans. (In fact their brains were larger than ours!) They made wood, bone, and stone tools, and the discovery of healed fractures in some skeletons suggests that they cared for their sick and wounded. They buried their dead and may have used body paint, and they constructed large shelters out of animal bones. (They also may have practiced cannibalism, but then, so do some modern humans so you can’t hold that against them.) Neanderthals have long been thought of as pure carnivores, surviving by hunting mammoths and other big game, but recent discoveries show that they ate plants too.  Evidence in a cave in Gibraltar, the most recent Neanderthal site, shows that they even foraged from the sea, much like the humans who used the cave thousands of years later.

There is good evidence that Neanderthals used language, and there are even some speculations that their language pre-dated the separation between speaking and music – that it was a hybrid of the two – something that just screams (sings?) to be used in fiction.

So why did the Neanderthals go extinct if they were as smart as we are, significantly stronger, and geographically widespread? There are several theories. One, put forward in the book “The Humans Who Went Extinct: Why Neanderthals Died Out and We Survived” by Clive Finlayson, is that they were simply unlucky. It appears that Neanderthals hunted primarily in wooded areas, ambushing their prey using short spears and relying on their strength to bring the animal down. As the climate changed, the forests receded and gave way to wide steppes. Ambush hunting is less effective out in the grassland: it favors a hominid species specialized for long-distance walking or running, who use projectile weapons. That’s us.

Simulation of the spread of modern humans into neanderthal territory, beginning 1600 generations ago. Neanderthal territory is light gray, homo sapiens territory is dark gray, and the black band indicates areas of coexistence.

Another theory says that Neanderthals competed – perhaps violently – with homo sapiens and that we eventually won. This scenario is appealing from a fictional point of view because it goes against preconceptions and lends itself easily to the tale of a noble species of intelligent (perhaps even musical) Neanderthals being wiped out by a smaller, more devious species of humans: homo sapiens.

Of course, you can go completely in the other direction too. Another theory is that Neanderthals and humans interbred to the point where we stopped being different species. Some Neanderthal remains are sufficiently well-preserved to extract DNA, and the DNA of non-African humans include some portions that match pieces of the Neanderthal genome. Recently, DNA recovered from a 41,000 year old finger bone found in Denisova cave, Russia, shows that it came from a species that is distinct from both Neanderthals and humans, but which shows some degree of interbreeding with both.

My suspicion is that all of these theories are at least partially correct. It is conceivable that even as Neanderthals were dying out as their forests receded, humans could have accelerated their demise. And, knowing human nature, I wouldn’t be surprised if some interbreeding occurred even as our species was killing off the Neanderthals.

All of this evidence for coexistence between humans and other hominids is a ripe setting for fiction much like modern fantasy but with the added benefit of being somewhat realistic. Add in the various exotic mammals that still roamed the world and the changes in climate that drove the migration or extinction of entire ecosystems, and the stories practically write themselves.

The wide geographic range of earlier species like homo erectus, and the persistence of pockets of similar species until quite recently, also spark the imagination. Almost every culture in the world has tales of human-like creatures that live in remote locations on the fringes of civilization. Could these stories be rooted in our distant past when they were not fiction at all? Could the revulsion triggered by the “uncanny valley” be a deep-seated instinct based on a time when there were other humanoids out there, competing with us?

There’s no reason that fantasy has to be confined to a pseudo-medieval Europe populated by the same old fantasy races. Long ago, our planet really was home to multiple species of human, and they fought and loved and explored and invented and sang songs into the night. Let’s hear their stories.



Building the Dragon II

Part II (Part I is here)

Continuing the question: will it breathe fire?

I threw out the idea of fire-breathing being a mating display, as there isn’t any biological need for a creature to breathe fire. Let’s put aside the question of why and look at how.


One commenter brought up hydrogen gas, which has the double advantage of being both flammable and lighter than air — it can be used to lighten your dragon for easier flying, whether by storing it on hollow bones or a gasbag (like a bullfrog’s throat pouch, or perhaps by going all the way to designing a zeppelin-like dragon).

However, hydrogen gas isn’t as common in nature as one might hope. Generating it by splitting water is simple — if you have electricity. Electricity-generating organs do exist in nature, of course, but most of them generate only mild fields. A small, specialized organ generating enough current to split water into component gasses could work, given a ready supply of water and enough metabolic energy to generate enough gas.

Hydrogen can be produced by some forms of algae (there has been some research on that in the bio-fuels field) but those require sunlight and the inside of a dragon is notoriously dark (or can you fix that?) Some sort of symbiotic microbe in the dragon’s gut, generating hydrogen from yesterday’s lunch, may be your best bet — your dragon gets his gas with minimal effort.

One more side note: no need for your dragon to eat rocks. Hydrogen is everywhere. It’s just a matter of separating it out.


Far less sexy than hydrogen, admittedly, but methane has the advantage of being easy to generate using existing microbes. It’s generated in the gut by bacteria which require neither light nor air, and could be accumulated in a specialized organ for siphoning back toward the head for ignition.

Or, you could be really brave and let the methane continue on its way to be expelled in the usual manner with a less-than-usual ignition organ under the tail… so that both ends of your dragon are equally dangerous… hey, it could still be a heck of a mating display.

And a non-flammable option


Hydrochloric acid, as produced in the stomachs of meat-eating animals, is quite able to burn exposed skin and eat through fabrics. More potent acids like sulfuric or nitric acid aren’t produced biologically but if one can invent a tough enough organ to store the stuff, I think it could be made quite plausible.

Unlike fire being a mating display, acid spraying makes more sense as a defensive mechanism along the lines of secreting surface poisons or explosive defecation. An acid-spraying dragon may well be short on the fangs and claws and other armaments, eat things that don’t need intensive hunting and killing, and be subject to predation by bigger, scarier monsters.

Which could be just as interesting as your standard-issue dragon, of course.

Building the Dragon

Part I (Part II is here)

Everybody loves dragons. And while wingless ones built along the lines of Komodo dragons or alligators can be a viable part of your fantasy ecosystem, let’s admit it. We want them up in the air and breathing fire or electricity or something fun.

A quick survey of existing flying creatures: the flying fox can get as large as 2.5 to 3 pounds and a wingspan of nearly four feet. The harpy eagle‘s wingspan can be 6 to 6.5 feet and they top out at 20 pounds or so.

Mind you, I would not want to meet a 20-pound dragon with a 6.5-foot wingspan, or be on the wrong side of its talons. And a hero would look really bad-ass when his pet swooped down to land on his (steel-reinforced) falconing glove.

Quetzalcoatlus scale comparison, by Matt Martyniuk (Dinoguy2), Mark Witton and Darren Naish, courtesy of Wikimedia Commons

In green, the Quetzalcoatlus northropi, with a human for comparison. Modified from a diagram featured in Witton and Naish (2008).

Let’s aim higher.

Quetzalcoatlus is the largest flying dinosaur discovered so far. Estimates vary, but it seems safe to assume a wingspan of 30 to 35 feet (9-10.5 m). Weight estimates have varied from as light as 150 to over a thousand pounds (68-453+ kg) (in a 2010 estimate generated mathematically). The first question is, of course, can this creature get into the air? Ostriches are the only current birds of similar weight — and they top out at 300 pounds.

Will it fly?

The issue was addressed by Witton and Habib in a 2010 paper on giant pterosaur flight dynamics. Their analysis of existing fossils and reconstructions of musculature led to some interesting possibilities. For their analysis, they settled on a Quetzalcoatlus of 32-36 foot (10-11 m) wingspan and 400-550 pound (180-250 kg) weight. Witton and Habib assert that these giant pterosaurs had sufficient bone strength and muscle for flying — with some mild caveats.

  • Assisted launching. The pterosaurs may have launched themselves with a strong jump followed by vigorous flapping. You can find a wide variety of birds using this strategy, especially larger ones like eagles. Others have suggested that pterosaurs may have used the running-start approach to launch or jumped off cliffs to get that initial burst of speed. Witton and Habib lean toward the jumping method, though.
  • Soaring. Rather than flapping constantly, pterosaurs may have done most of their flying by finding thermals and winds to soar on. Albatrosses and vultures do this a lot — it saves a great deal of energy, and when you’re big you need to save energy.
  • Moving on land. Pterosaurs were not built for it. But the authors theorize that they may have been able to get about by hopping/jumping (saltation, as sparrows do) and possibly bipedal walking (many birds do this — ducks, robins, hawks…).

What does it eat?

Witton and Naish wrote a 2008 paper on morphology, in which they addressed some of the questions of the morphology and ecology of giant pterosaurs, including Quetzalcoatlus. It’s good reference material, but chances are you aren’t building a dragon with a stork-like beak and a neck that’s long like a stork but less flexible — like a lizard. They lay out some reasonable options for such creatures, but a traditional dragon with a shorter muzzle, teeth, and greater neck flexibility will have more predatory options.

Bearing in mind the three rules of predators as formulated by me (and only me): 1. Don’t get hurt. 2. Don’t work too hard. 3. If it gets you food, do it. Also bear in mind that while an earth-bound predator can gorge on a kill and then slink away to digest, a flying predator can’t eat so much at once that he can’t fly away if threatened. Many small meals throughout the day are probably the best strategy.

  • Fishing. This is a perfectly good way to acquire a relatively large amount of calories with a reasonable amount of work. Given the general structure of a Quetzalcoatlus-based dragon, I would think that divebomb-style fishing (as done by ospreys and eagles) could work.
  • Carrion. It’s not glamorous, but it fulfills rules 2 and 3.
  • Traditional airborne hunting. This could be hunting birds, other dragons, or earth-bound prey, as falcons and hawks do. But bear in mind the stipulation about over-eating and the fact that it’s easier for a rabbit to hide in a forest than for a fish to hide in a lake. Hunting animals that congregate in large groups in meadows (or other open terrain) will make hunting easier… but also remember that we’re talking about a 30-foot wingspan dragon blotting out the sun. It’s difficult to miss that flying overhead, one would think. Or can you find a work-around for that?

Will it breathe fire?

Scientifically, the problem with breathing fire has always been the question why does it need to? Anne McCaffrey came up with one of the best answers (we bred them to do it) but in strict ecological terms, teeth and talons are quite sufficient for all your hunting needs. And if a feature isn’t useful to a creature’s survival, it isn’t done. Right?

Well, except for things that the opposite sex finds attractive. Such as peacock tails, silly dances, and the ability to compose sonnets.

Your mission, should you choose to accept it: imagine fire-breathing (or lightning bolts, what-have-you) as a mating display. We will get back to this in Part 2.

Life, Death, and Water Mythology

I’ve been anxiously awaiting the release of Disney’s Pirates of the Caribbean: On Stranger Tides for some time. The movie is loosely based on Tim Power’s  novel by the same name. In anticipation of this event, I talked my fearless editor into letting me celebrate with a post or two.

While chatting about potential topics related to the movie centering around water and the fountain of youth, she mentioned water myths in the context of space travel. I was surprised at first. I so seldom think about such things when I consider space exploration. Sure on alien lands, encountering alien cultures I can absolutely see it. I just don’t think of any kind of belief system in relation to spaceships and travel. The one exception might be John Scalzi’s  The God Engines.

Ok so let’s try an experiment. I am going to share with you locations, creatures, and ideas both real and fantastic that belong to our collective human mythology involving water. They will be direct quotes from various sources.  As you read over them, try and think how they might fit into stories involving space travel. Are you with me? Good. Read the rest of this entry »

Big Speculation – Fat Fiction

 More people on Earth are overweight than underweight. Yet the trajectory of human body size in science fiction and fantasy could be graphed with a line sloping sharply in the opposite direction. Where’s the fat? 

Authors, we’re not doing anyone favors by dodging the facts of life. Fiction’s greatest purpose is to address reality in a way that frees readers to relate to it without suffering it directly. We certainly don’t make our writing any better by preempting the fat (or dark skin, or women, or children). If anything, we sabotage our stories by depriving our characters of experiences that matter to real people living in the real world. 

Of course this problem has complex origins. Western fat bias is going global, and escapism will always have wide appeal, after all. However, I suspect part of the problem stems from a generally poor understanding of what fat is, how it works, and why it’s important. 

Here’s the skinny on fat: Every cell in our body requires cholesterol to function. We need fat to live, so there’s no point demonizing it or pretending it has no place in speculative fiction. Furthermore, fat cells – collectively, adipose tissue – do so much more than store excess calories. Fat behaves like the other organs of the body; it actively participates in metabolism, yes, but it also influences our neurochemistry and immune system

There is more to talk about than weight loss when it comes to fat. Isn’t it curious that different types of fat deposits predict different long term health outcomes? Isn’t it more interesting that one’s sense of satiety, of ‘fullness’, depends more on the brain’s ability to receive certain chemical signals from the gut than it does on how much is eaten? Isn’t it downright fantastic that, once upon a time, being fat was socially advantageous? 

When I browse a bookstore, I see vast expanses of neglected frontier. Even the science fiction and fantasy sections are narrow and homogenous. If our art imitated life, I’d see two covers with ample main characters for every one featuring an athletic lead. It makes me want to write in the gaps. To fill the void in our fiction with fact. And fat. 

Five minutes of speculation later, and I already have more ideas than I have time to develop: 

- Aliens make first contact and assume that the widest person on Earth is our leader. 

- A zombie epidemic starts with an appetite suppressant, and only the obese outlast the horde. 

- Santa Claus trims up and loses his powers, and is nightmarishly replaced by Rumpelstiltskin. 

- It turns out that the fatter one’s body, the greater one’s magic, but because using magic burns calories at a phenomenal rate, nearly all magic is applied to agriculture.

What’s your big speculation?

(W)hole Hearted

In preparation for this month’s post, I’ve been reading up on the heart. The post was inspired by my friend, Francesca Forrest’s, recommendation that I read The Sublime Engine: A Biography of the HUMAN HEART by Stephen Amidon and Thomas Amidon, MD. NPR had done a piece on the book discussing the man that toured Europe with a hole in his chest that allowed folks to see his heart hard at work deep within his chest. I was intrigued.
