Is forcing domestication simply for the sake of companionship morally just? Thus, selecting for “tameness” would produce systematic changes that result in the “domesticated” set of traits. From the richly-plumed red fox to the big-eared fennec fox, foxes look adorable. We became friendlier first, and then got smarter by accident. Belyaev began his experiment by taking 30 male foxes and 100 vixens from a commercial fur farm, bypassing the initial steps of domestication since these foxes were already tamer than ones from the wild. In particular, one under-appreciated point about our species is that we have, essentially, domesticated ourselves. That is intriguing, because serotonin is "thought to be the leading mediator inhibiting animals' aggressive behaviour." meet, and the fox bows back to her. The fox experiment showed that just by selecting for friendliness, all these other changes, including an increase in social skills, happened by accident." I think that these experiments are interesting and could bring positive outcomes or usefullness to humans, but it could reduce the excitement of visiting zoos because we have the choice of having a lion in our home. If anyone, blame the fur farms that began breeding these foxes to begin with. A remarkable resource for understanding the behavioral and morphological changes associated with early domestication is the so called “farm-fox experiment,” which has been conducted for the last 50 years at the Institute of Cytology and Genetics of the Russian Academy of Sciences (ICG) in Novosibirsk, Russia. In the late 1950s, Russian fox-fur-farmer-turned-geneticist Dmitry Belyaev set up a long-term experiment to find out whether he could selectively breed the … "The fox farm experiment was crucial, in that it told us that domestication can happen relatively quickly in the right circumstances," he says. So these pups slow down in development and heads are shaped round (definitely “cuter”) for instance: Essentially, he has turned over 700 foxes into a group of docile, human loving creatures. The aggressive and fear avoidance responses were eliminated from the experimental population. Also the article was really interesting, because his experiment somewhat paralleled the domestication of humans as well. The population of conventional farm-bred foxes is still maintained in Novosibirsk. Since mammals (and indeed, many vertebrates) share many things in common between these organ systems, it makes sense that breeding for this one trait would cause similar changes in all of them. Additionally, I wonder if there are larger implications for domesticating these wild animals in that it could offset the ecosystem. What I couldn’t stop relating this to, was babyness that infants have in order to create a nurturing reaction from caregivers. "Possibly the reason was that the cat was domesticated at a similar time, and supplanted the fox as a possible candidate to be domesticated.". It remains to be seen how much further in the domestication process the foxes can go. A forgotten Russian experiment in fox domestication By Jason G. Goldman on September 6, 2010 A Silver fox named Eblis. Foxes, like … He believed behavioural responses were "regulated by a fine balance between neurotransmitters and hormones at the level of the whole organism". The former goes to suggest that the pups are stunted in their growth and/or do not need the physical changes brought about by maturity whereas the latter suggests that the domestic environment is actually better for development than their natural environment. These foxes were called the "elite of domestication", and as the generations passed the proportion of these elite cubs grew. This review is a summary of recent research focusing on the current knowledge of the genetic contribution to behavior in the Canidae family. Wouldn’t setting animals free into an environment to which they would be significantly maladapted be just as questionable as keeping them in this manner? http://www.youtube.com/watch?v=GjqkBcZLwVY, http://peakyourinterest.files.wordpress.com/2010/09/pup3.jpg?w=300&h=180, http://fubini.swarthmore.edu/~ENVS2/S2007/llam1/horses1.html, Adam Miklosi's Lab (Eötvös Loránd University, Budapest), University of Florida's Canine Cognition & Behavior Lab. In this experiment, not 100% of the foxes were domesticated, which makes me wonder, would this margin of error just be a typical margin of error that every experiment may have? Domestication only happens over a long period of time through selective breeding. Belyaev’s Hypothesis. So pet foxes are not generally a good idea. Unlike dogs and cats, the different species of fox have not been domesticated. In contrast to the dog that was domesticated prehistorically, the fox was domesticated in controlled farm conditions. They also attempted to touch or pet the foxes when they were two to two-and-a-half months old, for strictly measured periods at a time. While these theories are most certainly plausible, I couldn’t help but think that maybe the feminine traits of the more docile foxes are closely tied to the success of a fox in the wild– that is, the more ‘aggressive’ looking foxes (i.e. At an experimental farm in Novosibirsk, Siberia, geneticists have been working for four decades to turn foxes into dogs. http://peakyourinterest.files.wordpress.com/2010/09/pup3.jpg?w=300&h=180. In addition, genes had to be responsible in part for an animal’s tamability. Also could the experiment work backwards? In other words, genetic variation at other loci (areas of the genome) could suppress or alter the effects of a gene. Read about our approach to external linking. For example, the drooping ears of the domesticated foxes might be a result of slowing down the adrenal glands. An even higher-scoring category emerged in the sixth generation, foxes in Class IE known as the “domesticated elite” demonstrate the following behavior: By the tenth generation, 18% of the pups were elite; by the 20th, 35% were elite; today 70-80% are considered elite. Belyaev believed that these changes were the result of selection for domestication. Just a thought! This would mean that our prosocial skills, the skills that allow for cooperation and friendliness, were what made us successful.". Meanwhile, Britain's urban foxes are often described as being bold and brazen around humans, compared with their countryside cousins. Through the work of a breeding programme at the Institute of Cytology and Genetics at Novosibirsk, in Russia, he sought to trace the evolutionary pathway of domesticated animals. In the late 1950s, a Russian geneticist called Dmitry K. Belyaev attempted to create a tame fox population. I also wondered if after training these foxes or any undomesticated animals to be domesticated, is it possible if their offspring would be naturally domesiticated or human friendly without tranining? What types of ecological consequences could result from this domestication? Such disruptions are due to selectively breeding for what is essentially a behavioral, not a quantitative, trait. Caging a truly “wild” animal (meaning, one that has never been under selection pressure for tameness) is certainly questionable from a moral standpoint. I dont believe that this experiment is sufficient to validate this theory. The fox experiment showed that just by selecting for friendliness, all these other changes, including an increase in social skills, happened by accident.". This article does a great job at demonstrating how foxes physical traits have changed after domestication.ex) the depigmentation, skull shape, etc. ", It was not just the foxes' personalities that were changing. “Dugatkin and Trut have collaborated to produce a well-written and engaging account of one the most influential biological studies ever: the fox farm experiment. The silver fox is a coat color morph of the red fox (Vulpes vulpes). Belyaev's aim was to create a genetically-distinct population, so he simply selected for particular behavioural traits. However, perhaps the most influential physical change was not an immediately observable trait, but rather a shift in the timing of development. They will stand and stare at passers-by on the streets and even approach people with food. The youngest fox, a vixen called Hetty, is extremely shy around people – even though she was captive-bred, and Bowler and his partner fed her through the night from when she was one week old. I also understand that Belyaev’s experiment was done in order to obtain knowledge but domestication of foxes has gone too out of hand. The domesticated silver fox kits started to appear in a variety of colors: piebald fox kits appeared out of nowhere, somewhere along the ninth generation. Others who have tried living with foxes report the same thing. Change ). The foxes at the fox-farm were never trained to become tame. He travelled to Russia on the Trans-Siberian railroad to visit the farm, in order to compare fox cubs with dog puppies for a study published in 2005. Many facts were learned about genetic selection. Are we forcing these animals in a situation that contradicts their nature? The interplay between behavioral genes and physiology and morphological development is significant. While the conditions imposed by the experimenters do seem harsh compared to what we are used to seeing, remember that the Class III foxes are still far more tame than wild foxes. Belyaev died in 1985, but the project is still ongoing. With the downturn of the Russian economy, the fox population is dwindling without the financial means to support it. Those that hid in the corner or made aggressive vocalisations were left in the farm. I agree with Becky that it would be interesting to do the same experiment on other animals. Figure 1. This could be potentially dangerous. As a result, these foxes, which are artificially selected for, happen to pass down their genes to the next generations, thereby giving the dog-like domesticated fox we see today. "We always assume that intelligence is responsible for our success," says Hare. All these changes were brought on by selecting for one trait: tameability. For example Belyaev has cages, bountiful food, medicine etc. In summary the results from this experimented demonstrated that wild foxes can be quickly domesticated within nine generations to have traits that allow them to be handled as tame “pets” of humans.

In fact, Belyaev and Trut soon found that it was not just the foxes' personalities that were changing. Really thorough and interesting article, guys. Even though Flossie was not happy to see the fox, she was polite. such as we don’t argue that a bear has every right to eat fish, we have every right to preform acts that benefit us, without using absurdly inhumane methods that is. They started to sell the foxes only after they began to lose funding (a better alternative, in my mind, than selling them back to the fur farms). The foxes could 'read' human cues and respond correctly to gestures or glances. Therefore it is following the laws of nature that allows us to do so, therefore its the foxes role to comply. They also argue that the dominant traits they observed could not have been “hidden” in the heterozygosity of parent foxes. Here on a farm, outside the city of Novosibirsk, the experiment still continues today, overseen by Dr Lyudmila Trut. Brian Hare is associate professor of evolutionary anthropology at Duke University in Durham, North Carolina and author of the 2013 book The Genius of Dogs. If all or most animals have similar genetic components to domesticity, it might make locating the genes for it easier. Stalin's death in 1953 gave scientists more freedom, but in the early years Belyaev nevertheless worked under the cover that he was breeding foxes to make better fur coats. In accordance with that, it also seemed contradictory to say that pedomorphosis is due to the “stresses of captivity” while also saying that female foxes had bigger, earlier, and more frequent litters, insinuating that the foxes felt more secure and comfortable mating in domesticity. "The current situation is not catastrophic, but not stable at the same time," writes Kharlamova. Also, their new owners may not be able to care for them, which may lead to a large number of orphaned foxes. Animals that were friendlier and tolerant to human touch, even to a small degree, were picked out. The vocalisations they made were different to wild foxes. They are not trying to create the next pet craze. The domesticated foxes had floppier, drooping ears, which are found in other domestic animals such as dogs, cats, pigs, horses and goats.
