Turner, J G discussed on The Best of Stuff


That was the point of comparison he was trying to make, and so Darwin writes that in domesticated strains of animals we constantly see examples of adaptation quote, not indeed to the animals or plants own good. Good, but to man's use or fancy, some variations useful to him have probably arisen suddenly or by one step, so it has probably been with the turn spit dog so we know that in the middle of the eighteen hundreds when Darwin's writing about this would have been a common enough like a well-known enough phenomenon to have a turn spit dog working in a kitchen that he could just casual reference to it and people would know what he was talking about. Oh. Yes, that dog that is! is so well adapted to turning a wheel. Kitchens so, but the question kind of becomes. Is the turns bit dog like a are? These dogs bred for this work or you? Merely selecting dogs to fulfil the role of the turns fit right, and I think it's possible. Some combination of the two right that dogs with initial bits of characteristics were selected for the job early on, and then maybe they were bred to bring out certain characteristics that made them especially good wheel. Turner's right in this. This would be the same process that you would get. Say a good rat chasing dog, right? You can imagine like early on people. Saying I need some dogs to go get those rats. Give me some short legged dogs right, and then you know the the the breeding commences, and you get increasingly breeds of short legged dogs that have a real tenacity for chasing rats right? If you've got a batch of maybe the two that catch most rats, you breed them together, and that makes the next generation. At the time and author named J G would mentions the turns bit dog in his illustrated natural history in eighteen, fifty three, but he writes that by his time the dog had become rare, and while it had previously been very common, then existed only in isolated regions, but in the seventeenth and eighteenth centuries turns..
