I was on the Ethology for Writers at Arisia this weekend. Here are my notes:
Definition: study of the behavior of non-human animals.Comments: There was a comic I saw years ago. A collection of different animals such as a horse, a monkey, a human, a giraffe, an elephant. In the thought balloon over each were the words “And God created <insert animal here> in his own image…”
The definition of ethology has that same sort of arrogance. Similar to the division of animals between invertebrate and vertebrate animals—as if vertebrates, which contain humans, were the important group and all other animals lumped together regardless of heritage or adaptation.
A better approach is to include humans in ethology as another animal. Or, it’s possible, the distinction allows uncorrupted study of non-human animals and the inclusion of humans would inevitably torque the study around us.
As writers, we are writing for an audience of humans. That constrains us.
I think, for our purposes, we can list a few basic principles:
- Behavior derives from evolutionary heritage and adaptation. This does not limit its capacity but it does orient its expression. Humans have two hands and two eyes. What we do personally begins there. But it could end with an enhanced human Shiva.
- Evolutionary change is drive by variation and natural selection. Organisms retain capabilities as long as they are useful and/or are not too expensive to remove. Evolution loves to repurpose otherwise “useless” components to new purposes. Horses run on their middle finger. The other bones have been repurposed to support that effort. Our reptile ancestors have many bones in their lower jaw. Mammals have but one—the mandible. Two of those ancient bones were repurposed to the mammalian middle ear.
- My definition of “conscious” is quite broad. It means the animal is aware of the consequences of its actions as an entity. The degree of this “consciousness” varies by species and individual. My suspicion is an ant is not conscious. A cuttlefish is. Once this awareness is in place, it changes the dynamics of behavior.
- Behavior, then, can be inherited (typical of stereotypy) or learned or a blend of the two. My own feeling is as we progress upward on the axis of stereotypy we probably progress downward on the access of consciousness.
- Common categorical behavior across the breadth of a species is probably indicative of some heritability. Unique categorical behavior within species groups is likely product of a cultural aspect. (By “culture,” I mean group behavior that retains knowledge independent of biology. I.e., termite hunting in chimps or sinking ships by orcas.) In human terms, common ground might be the existence of special procreative behaviors such as marriage, music, group organization. This capability is likely inherited. The individual instantiation of these categories is not inherited but preserved in the culture.
For purposes of fiction, I think we can broadly discuss two basic aspects of how ethology can influence writing:
- Behaviors animals have in common with human beings. E.g.: mammals rear their young. Humans, as mammals, do the same. Fictionally, this allows the reader to feel common ground to the animal/alien/mythic creature in question.
- Behaviors animals that are unique to them and not common with human beings. E.g.: cattle offspring are born quite ready to walk, move, and eat—given a little start up time. Human offspring can’t even thermoregulate properly for several months. Fictionally, this creates contrast between the human and the animal/alien/mythic creature.
All animal behaviors (as well as human) exceed the bare necessity required by survival and reproduction.
The advantage of cognitive mediated behavior is that it enlarges the behavioral repertoire of the animal to handle future events that cannot easily be extrapolated from past adaptations. Evolution does not know the future. However, animals that are in general better prepared for an unexpected future do better than more specialized animals over long periods of time. However, repertoire can only derived from the animals evolutionary heritage. If it’s advantageous for humans to have a third eye that can see x-rays, we’re not going to develop one because we don’t have the biological mechanism to present it and have it honed by natural selection.
There’s another approach where a given animal is given human characteristics—the Mowgli stories, for example. The tension between the animal nature and human nature of the characters drives the dramatic tension.
Okay, okay. Enough about analysis. What can we use?
I’m in SF so I’m not going to play in the fantasy camp.
If you’re world building in SF you’re interested in ethology for three reasons: aliens, beasts, future humans. (Which is another word for aliens.)
For my money, over the last billion years or so, earth has pretty much explored all possibilities of form given the earth environment. For physiological adaptation, you can go back to Ediacaran all the way to the present. But you won’t get much in the way of behavior. It’s pretty certain that some dinosaurs nested and probably reared their young. But it’s debatable.
Behavior is the province of the present. I’d start with the character goal of the alien/beast/future human.
Vertebrate examples:
- Stickleback fish and some other similar fish. The female leaves the eggs with the mated male. The make cares for them and doesn’t eat for the duration of the hatching and raising of the fry. If it survives the experience, it will make no distinction between the fry and other pray. Some sharks nurse similarly.
- Many reptiles are the deposit and leave them there philosophy with their offspring. Of those, some engage in cannibalism—that is, they make little distinction between same species and extra-species meals. However, some reptiles—notably alligators—make and guard the nest and will actively come to the defense of the young. At some point, the young mature enough to leave the area near the nest and from then on are considered a competitive adult.
- I like cuckoos. They are a high stereotypy—and probably less conscious—organism. The adults have little interaction except for mating. Since the cuckoo leaves its eggs in the nest, there is no rearing. Consequently, there has been shown some specialization of cuckoo subgroups towards particular species with the newly hatched young more closely mimicking the host species.
- There are many examples in primates, elephants, cetaceans, and birds where quite sophisticated behaviors and cultures exist in the absence of obvious language—at least, language as humans perceive it. Corvids have been shown to have knowledge persist across generations without the benefit of language. No one knows how.
- There’s some evidence that dolphins can project sonar images of an object under discussion. To my knowledge, this is still debatable. While it is in the bandwidth of their sonar, it’s not clear how to prove this.
- A lot of vertebrate behavior is oriented around the ecological niche they have to live in. For example, elephants have a matriarchal society. Non-forest elephants are incredibly destructive to the local are. Before they were decimated and the area around them destroyed, they had a roughly fifty year circle where they would cycle through. It’s not an accident that this is a bit less than the age of a matriarch. It gives a young elephant time to cycle through the path and then remember it for the next round.
- More on elephants: apparently, the older bull elephants tended to keep younger bulls in check. However, they also attract poachers. Without the older bulls around, the younger bulls are much more destructive.
- One thing that I wish were more explored in fiction is the cross-species cooperation. Cooperation is selected for at least as much if not more than direct competition. There are a number of examples:
- Crocodilians and wading birds. The birds tend to nest near the crocs. It’s not clear what the mutual advantages are. One hypothesis is the crocs scare off the egg stealers and get the tasty chicks that fall out of the nest. I can buy the egg stealers but the birds would have to lose a lot of nestlings to make it worth the crocs while. Also, given the normal diet of the croc, a nestling is pretty small potatoes.
- Ostriches and zebras: sight vs smell. This is a fairly obvious case of mutualism. It’s also the case that there’s no possible competition between them.
- Coral grouper and moray eel: if the grouper’s prey goes into a rock, it signals the eel to go after it. The grouper gets the shredded bits.
- Remoras and sharks: remoras have been following sharks so long that they’ve developed an attachment sucker on their head. They eat the remainder the shark leaves behind. Not so sure what’s in it for the shark.
- Coyotes and badgers mutually hunt ground squirrels.
- Tarantulas and frogs: tarantulas protect the frogs and lets them live with her. The frogs eat the ants that are trying to eat her eggs.
- Pistol shrimp and goby. The goby sees predators and alerts the pistol shrimp. The pistol shrimp digs a burrow for them to both live in. They pair bond for life. Figure that one out.
- Ravens guiding wolves to prey
- Carrion beetles with mites. Carrion beetles lay their eggs in the carcass. The mites eat any eggs other than the carrion beetles. Beetles carry the mites from carcass to carcass.
- In the 1860’s orcas drove baleen whales to a whaling station in Australia where they would be killed. The whale would be left out overnight so the orcas cold feed.
- One of the more interesting ideas to come out of paleontology in the last decade is the predator/prey relationships. If you examine something like the Serengeti, you’ll see a bunch of animals fitted closely to their niche. Small cat sized predators. Medium sized predators. Large predators. Similarly, you’ll small herbivores, medium, etc. Enormous species diversity. However, if you look at the paleontological record in the Jurassic or Cretaceous, you won’t see this. One hypothesis is that even very large animals hatched out at a fairly small size. This meant you had a single species that, as it grew up, occupied the size niches from birth to adulthood. A baby T-rex for a leopard. A juvenile T-rex for a lion. And an adult T-rex.
Invertebrate examples
These are a lot harder to tease out. There have been a few studies of the neurology of invertebrates showing that just random chemical variation can present multiple options for given behavioral decision. Some have interpreted this as “free will” or evidence of sentience. I’m not in this camp. It’s not at all clear to me that a planarian can possibly have free will.
We can’t conceive of exercising memory without consciousness. Therefore, it’s very hard for us to imagine how that happens. Instead, we place the burden of consciousness on the organism to make us feel better.
It’s fairly clear one can have multiple behavior options and intelligent decision making in the absence of consciousness. We see it in ChatGPT, for example. And, given such a system, there is a potential to select for intelligence as this gives better long term viability for the organism.
Thus, you can have complex behaviors without any associated consciousness.
- Cephalopods. You can’t have a discussion of invertebrate behavior without octopuses and cuttlefish. It’s not just a good idea. It’s the law.
- They have strong ability to solve problems.
- They modify their behavior based on the circumstances. During mating there are big tough guys and little not so touch guys. While the big guys are displaying, the little guys slide in and get the girl.
- Not sure they are actually conscious but they are the best candidate we have in the invertebrate world.
- They have a networked brain—this gives some credence to the idea that intelligence arises inevitably above a certain neural complexity. Or, at least, it presents the opportunity for evolution to select for intelligence.
- They do not have a social existence. Both O’s and C’s are solitary except at mating time. This violates a long standing hypothesis that intelligence arises from social interaction. Certainly, that correlation is viable in vertebrates.
- They no not have long lives. Neither O’s nor C’s live all that long. Breaking another hypothesis that long lives are necessary for intelligence.
- So, we have intelligent behavior in a non-social animal. This means that though it might have sophisticated behavior, that behavior is not oriented around a social existence. O’s have been shown to engage in behavior that might be construed as play. How does play help a non-social animal?
- Insects are another group being investigated. A lot of work has been done with honeybees and bumblebees. They learn. They appear to have the capacity to mitigate a behavior based on a previous state. I.e., they can have an “emotional” state going into a task and have that state affect the outcome.
- Cost/benefit analysis is rampant in invertebrates. It’s been demonstrated over and over again. Crayfish make informed decisions when presented with a positive appetite reward coupled with a potential predator signal. This sort of behavior is shown time and again in cockroaches, bees, ants, etc.
- Eusocial insects (bees, ants, termites) do seem to have an “intelligence” that is embodied in the group rather than in individuals. That is, interactions between members of the group produce positive outcomes even though the individual actions may be quite simple.
Examples in fiction
There was a very interesting story I read a long time ago about a frog-like alien and a human teaming up for a goal. All of the story from the set up to the finish are lost to the mists of time but the character of the frog alien contrasting to the human remains. The frog alien only responded to its own self interest. It was not interested in friendship with the human, did not care for him—did not care at all. The frog had only self interest in mind. He was the perfect rational economic person. The human, on the other hand, had feelings of honor, obligation, and friendship.
By the end of the story the maguffin was achieved (that is another panel) with the human baffled and confused and the frog alien, having achieved its goal, moves on. I think there might have been a sort of coda where the frog alien decides it’s in his own best interest to maintain a relationship with the human.
The point of the story were the irreconcilable differences between frog and human. They could achieve their goals together but had little common ground.
Larry Niven and Jerry Pournelle postulate an elephant derived alien where the behavioral paradigms were based on acts of dominance and submission—which humans kept screwing up. The aliens were clearly vertebrate mammalians—much closer to us than other phyla.
In my own work, I invented the Centaurs for the Future Boston anthology. Centaurs resemble a preying mantis top stuck on a sow bug body. They were context driven—that is, were a more digital kind of conscious rather than our continuous analog version. They were also laid their eggs in the sea and the survivors returned to their ancestral home as larvae which pupate into an adult. Thus, there are no Centaur children and only intellectual husbandry to keep the adult population from eating the offspring. I got this from a lot of invertebrate groups and the way some vertebrates care for their young by not eating rather than eating them. When the “not eating” period is ended, the offspring might be fair game.
