50 Years of Domesticating Foxes For Science

gamebittk writes "In 1959, Soviet scientist Dmitri Belyaev set out to breed a tamer fox that would be easier for their handlers in the Russian fur industry to work with. Much to the scientist's shock, changes no one had expected emerged after just 10 generations. The foxes began behaving playfully, were smaller in size, and even changed color — much like dogs." Belyaev died in 1985, but the experiment continued (PDF) in his absence, and to this day provides strong evidence to parts of evolutionary theory. The experiment eventually branched out to involve other species as well.

  1. Playing God by Potor · · Score: 4, Informative

    All our science and technology is based on the idea that we can understand, control, and improve nature.

    Playing God, in the Xn tradition, is creatio ex nihilo. Tweaking nature - even with catastrophic results - is not playing God.

    Yeah, well, you started it, didn't you? Of course, like all master race discussions, yours appears to start with a couple of false assumptions and goes from there.

    "As I read through the article, blue eyes, fair skin and hair were as indicated as behavior."

    No, they weren't. Even the short article notes that Belyaev selected foxes based on which ones snapped at him when he offered his hand. Changes in coat colour (similar to those observed in dogs vs. wolves) were noted as a surprising incidental result. The more recent actual paper also linked mentions that those changes are likely a side effect of general changes in the timing of development, and are similar to mechanisms seen in dogs.

    "And in the articles, it was by selective breeding with these patterns in mind, that these new foxes and rats were created."

    No, it wasn't.

    "I am trying to avoid presenting this as an argument for racism, but I think it is almost instinctive that darker skinned people are more feared than lighter skinned people."

    All your arguments for this belief are heavily based on what is likely your society of origin, the US, which has and continues to have a very uneven relationship with people who have dark skin.

    Oh you creationists are so determinedly ignorant.

    Secondly, it is not clear even from a biological point of view how a new complex system can arise by random chance, such as developing an entirely different organ for example in a very gradual way.

    It's perfectly clear how organs can result from evolution in a gradual series of steps. Here Richard Dawkins explains exactly for the evolution of the eyeball in so simple a way a way a child could understand. You'd benefit from watching the whole thing, but if you want to cut to the chase, the eye section starts at about 23 minutes in.
