discussion. The domesticated dog's ability to form strong social bonds with human beings is directly related to the wolf's prey drive.
I would also disagree with Coppinger's idea that because dog's don't always exhibit what is supposedly the final behavior in the predatory chain -- dissecting the dead animal -- because I don't see that as part of the hunt. It's what happens after the search, the stalk, the chase, the grab bite and the kill bite.
Let me start by saying that I agree partially. Whether a dog knows or what to do with killed prey does not take away from the hunt being a prey drive thingy.
Where I disagree is the assumption that the dog gets this from the wolf because it has not yet been proven that dog descended from wolf. There's no austrolepithicus for wolf to dog, so to speak. Even wolves are not in the same form or size as early prototypical canids. Of the two prototypes, what became wolves came from a canid 2 to 3 times the size of the current gray wolf. And what became smaller canids such as foxes and coyotes came from a smaller, more agile canid that also had more omniverous tendencies. The bigger canid died out because it wasn't a fast runner. As ungulates such as deer and antelope evolved to faster runners, the big, slow canid died out but smaller ones, closer to the size of the gray wolf that could average 40 mphs for 10 minutes survived because they could run fast enough for just long enough to catch the faster prey.
But nothing in your articles or even in evolution, both radially adaptive and non-radially adaptive theories has proven that link.
And there in lies another distinction. Radial adaptation states that a creature evolves something in response to survival pressure. This has yet to be proven and, btw, it was not the intent of Darwin's work to state such. What is just as likely and explains much more is non-radial adaptation. An organism mutates. In fact, every generation produces mutations. Anyway. Generation x has a mutation that allows it to survive better and longer and breed better and more proficiently. Eventually, that mutation becomes the dominant trait in genetic survival. Organisms that don't have the mutation die out, as a species or version of a species. We are the way we are because we have mutations that allow us to survive the environment better than neanderthal and that's why we don't have neanderthals anymore, except in geico commercials.
Believe me, I don't have a religious objection or anything like that to dogs evolving from wolves, I just don't see the evidence of such. But many others have believed in it because it fits in a paradigm that they prefer. To me, that's bad science, at best, creative fantasy. And it seems to me that, in your articles and postings, it is an assumption that conveniently fits, generally, into some of your theory but is not scientific proof of your theory.
I also understand that you are trying to say that dog's social bonding with human is a side-effect of the social behavior of canids that hunt successfully by social cooperation and you may be right and that would be one of the easiest, simplest explanations. Saying that it comes from wolves is where I draw the distinction and think that's a little too much salad from one leaf of lettuce.
Just as likely, dogs are social creatures, with a higher evolved social level because of their interaction with humans, which started with the mutations of dog that could eat human leftover food and digest it and the mutation of them interacting socially with creatures outside of their species. Socially interacting to the point that they take cues from us and let us do problem-solving, something wolves do not do. So, while social behavior in canids might be general, what dogs do, across species, would be something more singular to dogs, owing to specific mutation in evolution. He who gets the resources, survives. You have to eat, you have to breed.
Also, to address neoteny. That is used to describe dog behavior as equivalent to an eternal wolf cub. That might work as an ad hoc description but it contains the inherent assumption that dog descended from wolf, which is still not proven. It would be more accurate to say that dogs exhibit the social behavior analogous to what is seen in wolf cubs, though it is not proof of an evolutionary line. It is a canid thing, not necessarily a wolf thing, in so many words.
So, what I see in your theories is not so much scientific proof as I see careful selection of bits of data, assumptions, and perspective shifts to explain something a different way but not always accurate or applicable. In essence, defining a theory and finding ways to fit evidence to fit that theory, rather than always objective data analysis and theorizing for that data.
But you are in good company. Einstein built a theory and used lorentzian transforms (such as l' = (l / (1 - v^2/c^2))) to mash data to fit the theory. Certain politically connected professors decided that man is heating up the planet and changed data to match that (climategate, specifically the info from the Hadley CRU at the University of East Anglia in England, primary source for data for the IPCC climate reports.) In addition, the intimidated dissenting scientists with threats of physical harm and censure. But I digress. Nor am I implying that you are like those fellows. Just saying that there is a temptation to filter data to fit a theory, when it should be the other way around. Collect data, form theory. If new data shows flaw in theory, adjust theory or scrap it and start a new one. At least Einstein had that going for him, even if it turned out to be wrong, or more accurately, partly wrong. And later, he succumbed to the problem of fitting data to match theory.
There are times when I think you are close to finding a real answer and other times that I am not so sure.
