Are Dragons Real? What Is the Reason for Dragon Myths?

Do Humans Have Dragon in Their DNA?

Dragons are mythical creatures. Dragons do not exist. Dragons have never existed. Why, then, does every culture in the world have myths about dragons?

An Instinct for Dragons

David E. Jones, an anthropologist, has a fascinating theory about the prevalence of dragon myths in all cultures: Humans have dragons in their DNA. More precisely, humans have a fear of dragons in their DNA. Dr. Jones explains his theory in his book, An Instinct for Dragons.

According to Jones, the dragon embodies an instinctive fear of the three main predators who preyed on our mammalian ancestors. The three predators are snakes, large birds of prey (raptors, eagles), and big jungle cats (lions, tigers, and leopards). Individuals who instinctively fled these predators had a survival advantage that was passed on through their genes.

These instincts, buried deep in our DNA, were eventually expressed in depictions of dragons. The specific depiction of the dragon varies from culture to culture, but the three elements of snake, raptor, and big cat are almost always present. Dragons are a combination of these three animals—the reptilian body of the snake, the wings and sharp talons of the birds of prey, and the jaws (and sometimes the haunches and paws) of the big cats.

(Some depictions of dragons seem to have a lot of crocodile in them, so crocodiles may be part of this syndrome also.)

What Is the Basis of This Theory?

David E. Jones observed vervet monkeys in the wild. He noticed that there were three distinct calls that the monkeys made upon seeing the approach of a snake, a bird of prey, or a big cat. They made a different call for each predator, and each call elicited a different response from the vervets.

If it was a snake, they would move up or down a tree away from the snake; if it was a bird of prey, they would move down the tree to avoid the bird's talons; if it was a big cat, they would move up the tree away from the cat. These actions were only taken in response to the specific call, and each action was specific to the predator.

Our mammal and simian ancestors were much smaller than human beings. The predator animals would have been all the more terrifying and dangerous to these relatively small creatures way back in our family tree. With no natural abilities to fight these predators, the only chance for survival was flight.

Any ancestor who had the ability to recognize the approach of the predator and flee just a little bit faster than others would confer this genealogical advantage to its offspring. This instinct thus became encoded into the DNA.

Eventually, the three separate predator animals merged into one, the dragon, through a process called "clumping." Scientists who study the brain and learning have observed that humans have a tendency to "clump" (group) things together for easier recall.

Are Dragons Really Dinosaurs or Lizards?

While dragons have some features in common with dinosaurs—large size, elongated reptilian bodies—there are two reasons that dinosaurs are unlikely to be the source of dragon myths.

First, primates and dinosaurs did not co-exist. Dinosaurs were extinct before primates came into existence, so early primates and dinosaurs never crossed paths.

Second, the dragon myths are much older than the discovery of dinosaur fossils. Early humans would not have encountered dinosaur fossils buried deep in the earth's strata. Further, even if they had come upon dinosaur bones, since a fossil is seldom intact and since it is only bones without any clue to the outer appearance of the animal, they would not have been able to see a dragon as it is depicted in myth.

The Komodo Dragon, a large lizard, is still extant, but it is not the source of dragon myths. It is found in only one place in the world (a few Indonesian Islands) and dragons are worldwide. It lacks many of the features of the dragon. And most importantly, it was named after the dragon, a preexisting concept, and thus could not be the source of the myth.

What About the Other Features of Dragons?

Most depictions of dragons have horns, beards, a mouth full of sharp teeth, foul-smelling breath, and a loud roar. They often breathe fire. These features most likely come from the big cats.

Imagine our monkey-like ancestor face to face with a big cat ready to pounce upon him. The terrified prey would see the cat’s ears erect (looking like horns), its ruff and whiskers (looking like a beard), and a mouthful of enormous teeth. The prey would smell the foul breath that is typical of carnivores and would feel its hot breath—breath that might have felt as hot as fire to the terrified prey.

Any animal that just managed to escape this terrifying encounter would forever associate these features with danger. Even if the predator was not seen, these other clues would signal the flight instinct.

Why Are Dragons Often Associated With Water, Maidens, and Treasure?

The association of dragons with water probably arises because the predator animals are most likely to be encountered near water. All animals must drink—the monkeys must leave the safety of the tree to get water. And when they do, they might encounter a thirsty—and hungry—predator.

Dragons seem inordinately fond of taking maidens captive or preying upon them. Could this not be because of the importance of young women to the group? Young women, in particular, must be protected. Not only are they smaller and weaker than the males, but they bring forth the next generation. Any group that did not have an instinct to protect its maidens would soon cease to exist. The instinct to protect the child-bearers and rearers is necessary to ensure the survival of the species.

Dragons guarding treasure may reflect predators preventing the simian from reaching food. The fruit in the upper levels of a tree might be unobtainable because of fear of the raptor, and food on the ground (like roots, berries, insects) would put the simian in danger from snakes and big cats.

Why Are Chinese Dragons Different From Other Dragons?

In most cultures, dragons are fierce, evil, and bringers of death, but the Chinese see dragons as symbols of good luck and success. This different perception of dragons may be due to the fact that China was for centuries mostly isolated from contact with the rest of the world.

The Chinese people had fewer threats from outside of their own world, so they could "tame their inner dragon." There might also be some identification-with-the-aggressor and/or denial going on: We need not fear the dragon; he is our protector.

The Chinese dragon also differs from other dragons in that it is more like a sinewy snake with less of the bird and cat features.

Why Are Dragon Myths Most Evident During Certain Eras?

The ancient sea-faring civilizations had plenty of dragon myths, often sea dragons. Dragons may have symbolized the terrors of sea voyages. When a huge wave suddenly rose from the sea and engulfed a sailor's boat, could it not have seemed like a dragon?

Dragons were widely believed to be real during the middle ages. Knights often had to go out to slay them to save their town and country. The Middle Ages was a time of great social upheaval when humans first began forming communities larger than the family or tribe. The stresses and difficulties of this time of transition were personified as dragons. During this era, coats of arms and flags often depicted a dragon—it was a way to claim the dragon's fierce prowess for one's own.

Our civilization today is also under great stress. We may not believe dragons to be real, but they can become symbols of our fears of war and terrorism and so many other things that threaten our survival but are out of our control. I believe that games and stories about the killing (or taming) of dragons are a way for us to vicariously triumph over these threats.

Dragons are very popular. Hundreds of books, movies, games, and merchandise items feature dragons. There is even a genre of romance novels featuring shape-shifting dragons that can take human form.

Sometimes the dragons are monsters to be vanquished, and sometimes they are transformed into helpful companions, even pets. They have even been made cute and cuddly for kids.

I believe that whether we tame them or kill them, dragons symbolize our triumph over our inner fears.

Interesting stuff!

EbrithBowser: Birds so far as I know are not mammals. They lay eggs. mammals give birth to live young. I don't think I said anything about dinosaurs in this article. Small mammals (non-primates) did exist during the reign of the dinosaurs. Once the dinosaurs were gone, they were able to thrive and evolve into the mammals we know today.

EbrithilBowser on April 18, 2016:

I stopped reading when it said mammals came into existence long after dinosaurs died out. Not only did they co-evolve in the Triassic age, but mammals stayed small while dinosaurs started dominating every ecosystem, but also dinosaurs never went completely extinct because there are still birds around.

I think that it is possible that fears are hardwired into our brains. In his book, Jones discusses experiments that show babies will express fear if a shadow of an eagle passes overhead, but not for other shadows. As for me, I et scared if a cat crosses my path never mind a komodo dragon.

Susanna Duffy from Melbourne Australia on October 05, 2014:

Here there be dragons! Jones has an interesting theory although I wonder if ancestral fears are hardwired in our modern brains. Mind you, meeting a large Komodo dragon on a morning stroll is a frightening experience which certainly reduced me to the level of a gibbering ape

tony55: I see we share a fascination with dragons. If the thesis in this hub is correct, perhaps we like dragons because it is a way of dealing with our innate fear of the predators the dragon represents.
