All dogs are actually wolves. They are the same species of wolves but they are variety of looks. That's variation. All humans are just variation, but we are the same species. Like different breeds of dogs. German Shephard, Bulldog etc

So what is your point? Dogs and wolves have been studied using MtDNA just as people have. This was done at UCLA and I called them to get the results first hand when I read it in the newspaper. An Italian scientist (grad student) who was actually running the research told me that wolves fit within the dog range of variation. I told him I had rasied a wolf and now had a malamute. He said they tested malamutes and all wolf-like dogs as part of their research. The results of a genetic clock was that wolves and dogs seperated about 100,000 years ago. Most sources say dogs originally came from Asian wolves. This may mean dogs were first domesticated by Neanderthals. The only wolf in Africa is the Ethopian wolf. It looks like a jackel. There is no mistaking an Asian and an African wolf, at least phenotypically.
Wolves are wild. Dogs are domesticated, neontonous wolves. Humans domesticated themselves though culture. Wolves, it seems, resemble Neanderthals in relation to H. sapiens in some ways. The time frame is similar and in both dogs and H. sapiens, a degree of pedemorphism exist. Wolves and dogs interbreed freely.
If you look at the differences between wolves and dogs you see that the difference is quite huge at all.
Same is withe the physical and psychological characteristics of dog races which differ in very important features very from each other.
If you say thats the same with humans, it would be just one more argument against losing the generally better features/or useful regional adaptations with panmixing the races.
Sometimes breeded dogs are quite degenerated, but there are also vey good breeds/"races" and mixing them with f.e. degenerated races just means to lose this positive features.
And of course there was some effect via self-domestication in humans from at least from the Neolithization on, and some contraselective effects too...

According to the following article Homo sapiens sapiens domesticated the dog from an Asian wolf only 15,000 years ago. But that's about 100,000 years in dog years.Originally Posted by Dr. Solar Wolff

Dogs come directly from the Grey Wolf(canis lupis) not the jackal or any other type of wild doglike creature.
The joke with the dog years is not so false because the real important thing for evolution and mutations are the generations and dogs generate themselves and can be breed much faster than humans.Originally Posted by dishdawg
I dont know the exact age of dogs when they are fertile but its very early.

A mitochondrial study only establishes maternal lines, so I don't see how it can exclude the possibility of local grey wolf admixture, or admixture from other species of dog (all species of Canis can, I think, interbreed).
Human races are much older than dog "races", with more genetic differences. Most dog breeds are also manmade, something not really achievable with humans since we value freedom.
Here's an article, Solar, collaborating what you were talking about: http://story.news.yahoo.com/news?tmp...volving_fido_6
Unfortunuately, this article doesn't go into much detail. But even if domestic dogs' most recent common ancestor through the mtdna line lived 100,000 years ago, that doesn't mean they were domesticated that long ago. Perhaps a percentage of Asian wild wolves also share that mtdna. That's if they used mtdna; that article doesn't say what they used to make this determination.
This immediately enters "top five" in racialism.All dogs are actually wolves. They are the same species of wolves but they are variety of looks. That's variation. All humans are just variation, but we are the same species. Like different breeds of dogs. German Shephard, Bulldog etc
If accept it as truth then some human races are superior than others, because
German Schepard, Bulldog etc are definitly superior than pincher or puddel.
