50 Years of Domesticating Foxes For Science 347
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.
