Interesting point about the females having more docile genes. I also understand that Belyaev’s experiment was done in order to obtain knowledge but domestication of foxes has gone too out of hand. This suggests that human evolution selected for cooperation, tolerance and gentleness – and not, necessarily, for intelligence. and they also do not have any need to quickly mature since they are treated like pups pretty much their whole life (taken care of by a primary caregiver). We do not know if that is true. This article does a great job at demonstrating how foxes physical traits have changed after domestication.ex) the depigmentation, skull shape, etc. This was tested both when the pup was caged and while moving freely with other pups in a larger enclosure. As of August 2016, there are 270 tame vixens and 70 tame males on the farm. Caging a truly “wild” animal (meaning, one that has never been under selection pressure for tameness) is certainly questionable from a moral standpoint. To support its continued research, the Institute of Cytology and Genetics has turned to commercial ventures, such as selling the foxes for pelts or for pets. Would the effects be the same? Or is it merely that some foxes are more stressed (the immature foxes) while others feel safer (the frequently breeding foxes)? This made it clear that the process of domestication must place wild animals under severe selective pressure and extreme stress. More than 60 years ago, a group of researchers took a first step toward understanding the genetics of domestication by breeding wild foxes and selecting for domestication behaviors. Is it possible that we have already lost trace of certain kinds of dogs because those dogs were indocile? One example she described was a drop in the "hormone-producing activity of the foxes' adrenal glands.". Another interesting change was that the skull morphology became “feminized”—that is, the skulls of the males became smaller and more similar in proportion to those of females. But the domestic foxes carried them through into adulthood, suggesting the selection process had slowed down aspects of their development. Animals were domesticated in the past due to human necessity. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Belyayev è morto nel 1985 ma l’esperimento è tutt’ora in corso. In Russia, the famous Belyayev domestication experiment on foxes has been running since 1959. http://peakyourinterest.files.wordpress.com/2010/09/pup3.jpg?w=300&h=180.

Belyayev’s experiments were the result of a politically motivated demotion, in response to defying the now discredited non-Mendellian theories of Lysenkoism, which were politically accepted in the Soviet Union at the time. The mating season also lengthened, and some females even bred out of season, while still others bred twice a year. Their mating season was longer and they could breed out of season. straight tail, pointed ears, larger jaw and teeth) tend to do better in terms of hunting and mating than foxes which have effeminate features. Fox as a pet. If anyone, blame the fur farms that began breeding these foxes to begin with. If that is the case, then I would wonder if there are entire species that would be impossible to tame because of some inherent quality which cannot be rid of. The Belko Experiment has its fans, but clearly not enough of them showed up to see it in theaters, which is the first - and often only - factor in whether or not a sequel is greenlit. It is wrong to cage up wild foxes and new born pups just for experimenting and pet benefits. I dont believe that this experiment is sufficient to validate this theory.
