The thread is supposed to be about the genetics of dogs making them vicious.
Now we hear its about how bad the owners of some dogs are.
I am inclined to believe the purpose of the genetics argument is to show how the genetics of say, black people, make us dumb and criminals.
But a favored dodge around saying that is to say we, black people, make horrible parents.
So there is a parallel, but not in the breeding but arguing.
What I find really interesting is that this so called scientific arguement keeps popping up in a politics forum.
Shouldn't genetics vs environment be a better discussion?
Dogs are very different than humans. For thousands of years, humans have been deliberately breeding dogs to select for desired behaviors and instincts as well as for specific physical characteristics.
Terriers were specifically developed to be hunters of vermin, with some breeds specifically developed to go down holes after their prey. Nowadays, most terriers are pets rather than ratters. Herding dogs were specifically developed to herd/manage livestock, with different breeds developed specifically for different types of livestock. Hunting dogs: pointers were developed to locate or point certain game birds; retrievers to bring back birds which had been felled. Both types of dogs were specifically developed to have a 'soft' mouth: one that would not harm the game animal they bring back to the hunter. There are guard dogs breeds and some which were specifically developed to fight bears. These are just a very few examples of types of dog breeds developed for specific purposes.
I have seen some of these characteristics appear in puppies of only a couple of months old because a particular instinct was so well developed through breeding--that is, genetics. These characteristics are further enhanced through training. Or trained away from if the dog is a pet rather than a working dog. This holds true in modern dogs as well as ancient breeds.
Currently, there is a trend in at least my corner of the US to 'adopt' vs 'purchase' a dog from a rescue agency although as far as I can tell, there is significant money exchanged. People who don't really know better talk a lot about how much healthier mixed breeds are vs well developed breeds. The truth is that a good dog breeder will select for physical and mental HEALTH over all else with temperament, and breed conformation coming in second and third, ideally temperament coming in a very, very close second to physical health. Of course there are plenty of bad breeders who breed for looks first (whatever is in fashion) and puppy mills simply breed with no regard for anything other than volume. Mixed breeds may avoid some known genetic predispositions to some diseases--or they may exacerbate the worst of these diseases and temperaments. It's not fashionable to say so and people who 'adopt' mixed breed animals from shelters, etc. are quick to blame their dogs' shortcomings, health and temperament, on their early disadvantages rather than any genetics, genetics gone wrong or their own lack of training of the dog. At once, they over anthropomorphize their dogs and simultaneously absolve themselves of any responsibility for the dog's behavior and quirks.
I could go on but I don't think that is the intention of this thread.
Humans are quite different as there is and never has been as far as I can tell any planned breeding scheme to select for specific temperamental characteristics or talents. We do not destroy human babies which are born with serious deformities; we do not neuter or spay humans we deem unfit for breeding at early ages. Or against their will (historically, some exceptions have existed, though). We strongly disapprove of human eugenics, or at least almost all of us do, and many of us strongly disapprove, explicitly or implicitly of NOT practicing genetically planned breeding for dogs and other animals.
Within human beings, there are some behavioral characteristics which have some heritability: shyness being one that leaps to mind. There is some evidence that talents can be inherited although there is often such a strong reinforcement through exposure to sports, music, art, science, etc. that it is not clear where genetic influences start and where environmental influences begin. There is some suggestion that intelligence is at least partially inherited yet there are certainly many easy famous examples of offspring of famously brilliant parents not achieving nearly so high a level of expertise. Albert Einstein's offspring are easy examples of the limits of any inheritabilty of intelligence
But I think what Athena is getting at is that some people like to assign blame for inequality of groups of people, especially racial groups, to other people: either genetics or upbringing rather than acknowledge and accept the role that society as a whole and specific segments of society play in human intellectual and human social development.
