Did the Clovis people domesticate dire wolves?

The description of the paper comes from Facebook via Jess Ruffner:

Jeff Saunders has been looking at canids from Clovis sites. He presented results of his work on sites in southern Arizona at the Plains Anthropological Conference in October. He noted the presence of a diminutive form of Dire Wolf in these assemblages. Could this be evidence of early dog domestication in North America? We’ll be exploring this topic in more detail over the next few months. Stay tuned.

I don’t have a copy of the paper, but if I can see a copy, I’d be very grateful.

But am I surpised?

Heck no!

I’ve already discussed the possibility of the Hare Indian dog being a domesticated coyote, and there were lots of domestication attempts with wild dog species.

Only the Eurasian domestication experience with Canis lupus, the Holarctic wolf, ever actually amounted to much.

If these animals are dire wolves, then I have always had some questions about dire wolves.

Were they actually a unique species or were they nothing more than an early wolf subspecies that evolved to be really robust? And exactly how are they related to modern wolves and domestic dogs?

Most early wolf subspecies were not particularly robust, but they later did evolve into big hulking things, including a subspecies that lived in Alaksa during the Pleistocene. This wolf subspecies, though clearly within Canis lupus, but it was more robust and had very powerful jaws that were designed for hunting very large prey. These are the exact same adaptations that the dire wolf, which lived from the Central US to Northern South America, possessed– and for exactly the same purpose.

I also wonder if dire wolves became extinct entirely or if they contributed genes to modern wolves, dogs, and coyotes. If they contributed to Native American dogs, then they are likely lost, but if they contributed to wolves or coyotes, they could still have some traces of their dire wolf ancestry. I am assuming, as is most likely from observing their modern relatives, that dire wolves were fully fertile with both Canis lupus and Canis latrans.

I have not seen any comparative studies of dire wolf dna of any sort with those of modern members of the genus Canis.  Most studies on dire wolf taxonomy glean their analysis from comparative morphology– which is quite a dubious undertaking when we’re dealing with the dog family (see the red wolf debacle!)

So there are these questions.

And the fact that we have some evidence that Clovis people domesticated dire wolves is certainly intriguing.

***

The animal featured in the image above isn’t a domesticated dire wolf.

No.

It’s actually a recreated dire wolf, which is the American Alsatian breed.

Derived from mostly German shepherd stock, its breeders have tried to turn it into something like a dire wolf in phenotype.

How many different “kinds” of cat did Noah have on the ark?

This is another example of creationist stupidity– and crappy argument tactics.

Source.

To be far, we don’t have a satisfactory definition for species, as this post at BorderWars clearly shows.

But the term species is a whole less nebulous than the term kind.

I caracals and cougars aren’t the same kind, how on earth can one say that thylacines and dogs are?

LOL.  They actually do make this claim!

The law of unintended consequences usually raises its ugly head because people don’t think. You might be under the impression that the purpose this blog is to post nice pictures of my dogs, tell stories about them, and maybe educate some people about certain doggy things. And you’d be right. But the primary purpose of this blog is to make people think.

I do (or don’t do) things that tend to make people pigeonhole me. I keep lots of dogs. I breed them occasionally. I don’t compete with my dogs. I cross-breed. (I will also add that I live off-grid out in the middle of nowhere and am clearly crazy.) All of these things, alone and in combination,

She shows how the dog fancy’s inability to adapt to scientific facts and its desire to tarnish and harass those who don’t tow the party line on dog shows/trials/blood purity are ultimately going to be its destruction.

The animal rights fascists are pushing any number of draconian laws at both the state and federal level. They are using ideas that have currency among the pet owning populace, but because the dog fancy stubbornly holds onto its various traditions and shibboleths, it cannot effectively answer these people. Instead, it goes tars anyone who wants to fix with the label “animal rights activist,” which means that no one listens.

Not listening is perfect fodder for the AR’s, who then feed off it all.

The extreme AR’s want to ban all pets ownership and all domestic animals– and if they can’t do that, they can stop…

The Canids of Jaguar Cave

Canid jaw bones with teeth that were found at Jaguar Cave in Idaho. Dog jaws are on the right. Coyote jaws are on the left.

One of the most interesting discoveries of remains of Pre-Columbian domestic dogs in North America is at Jaguar Cave in Idaho’s Beaverhead Mountains.  The site is rather famous in that it has pictographs and hearths– definite signs of human habitation– and various bones from a wide variety of North American fauna, including the bones of the American lion (Panthera leo atrox).

It also has bones of dogs, wolves, and coyotes. Among those bones  are canid jaw bones– 43 of which have been idenitified as domestic dogs, 28 as coyote, and 4 as wolf.

These bones were initially assumed to be older than 9,000 years old, because it was believed to have been naturally sealed around that time. Further, the oldest hearth in the cave was carbon-dated to over 11,000 to 12,000 years of age.

It was initially assume that the dog remains in the cave were that old, and what was most interesting about the bone is they represented two distinct breeds. One of these was quite large– Labrador retriever-sized– and the other was smaller– around the size of a beagle.

If these bones were that old, it would strongly suggest that Native Americans entered North America with both large and small dogs. Indeed, they may have very well have had both large and small dogs when they came into the continent.

But the dogs of Jaguar Cave are not evidence for them.

When the jaw bones were directly dated, they were found to be only 1,000 to 3,000 years old.

Not ancient idigenous North American dogs.

But definitely Pre-Columbian.

However, the finding of these Labrador-sized Pre-Columbian Native American dogs that were indigenous to what is now Idaho put to rest the commonly held assertion that Native American dogs were always coyote-sized or smaller.  This is the assertion posited on my least favorite site on Native American dogs, you know, Kim La Flamme’s site, which, among other things, claims that all domestic dogs derive from coyotes– and claims that all the DNA evidence we’ve now compiled on dogs proves it!

There is no mention of the Jaguar Cave dogs on this site– because they are in direct contradiction to the assertion that Native American dogs were all mid-sized or smaller.

Some of the coyote or wolf remains at Jaguar Cave may be those of domestic dogs.  In hunter-gatherer societies, there was often only a paltry difference between a wolf and a dog, and in the early days of domestication, one would not be able to tell the difference between wolves or dogs– which is one reason why it’s been so hard to find good fossil evidence of early dog domestication. There is always an assumption that dogs will have shorter jaws and domed heads, but the early domestic dogs would not have these features– and neither would any dogs that happened to cross with wild wolves in those days.  These coyotes could have been semi or fully domesticated, as could have been the case with the Hare Indian dog. Or they could have been domestic dogs with a coyote phenotype.

The notion that the only Native American dogs that ever existested are those that were like coyotes is one of the most bizarre assertions I’ve yet encountered.

It’s also unusually racist.

Native Americans were not ignorant savages. They were not noble savages either.

They were highly skilled people who were able to master this continent, its mercurial climate, and its wildlife.

They were also skilled dog breeders, who produced all sorts of different dogs that ranged from diminuative techichis and Tahltan bear dogs to large moose-hunting dogs that belonged to the Mi’kmaq of the Maritimes. There were the wool dogs of the Salish that produced unusually thick wool and were kept on islands and fenced in caves to keep their bloodlines pure.

These people were more than capable of breeding dogs to fit their purposes.

The reason why someone would make the claim that all Native American dogs were of a very narrow phenotype is two-fold.  First of all, that particular site offers coyote-like domestic dogs for sale. If one says that all the dogs of the Native Americans were of that type, then one would be better able to market these coyote-type dogs. Further, the larger Native American dogs would have been the first ones killed off following European conquest.  The big dogs would have definitely been a threat to livestock. These big dogs also could have melded back into the wolf population more easily, and they also could have been absorbed into massive influx of Newfoundlands and other large working breeds that were swarming across the continent.

That would mean that the only dogs that likely would have survived near reservations would have been smaller but no so small that they would have been killed by larger dogs or wolves. Native peoples truly suffered as a result of colonization. Their whole existence was distrupted, and they couldn’t invest so much of their energy into maintaining different breeds or types.

Not a single dog in existence today is predominantly Native American in ancestry. The closest one can get to dogs that have a lot of that ancestry are the Carolina dog, which remained isolated on an island in the Savannah River between South Carolina and Georgia but probably was already heavily contaminated with Western dog blood by the time it got isolated, and the different sled dogs of the arctic, including the Alaskan malmute. These arctic dogs tend to belong to the various people called Inuit and Eskimo, which are not Native American in that they derive from the earliest Siberian colonizers of the Americas. They come from a later wave of migration.

The Labrador-sized dog of Jaguar Cave shows that should not believe everything that is written on the internet. You have to be willing to look at every claim a objectively. Some things are just wrong, but they sound so good that you want to believe it.

Don’t believe. Find out if it’s true.

The moose in Pennsylvania

According to Henry Wharton Shoemaker, moose were once found quite far south in Pennsylviana.  In his Pennsylvania Deer and Their Horns (1915), he describes historical accounts of Moose in the Lehigh and Delaware Valleys and in the Alleghenies between Pittsburgh and Altoona.

Alces americanus Jardine as a frequent visitor to Pennsylvania until the beginning of the nineteenth century is now fully established. Many old hunters aver that it was a permanent resident until its extermination, although S. N. Rhoads, the authority on such matters, can find no supporting evidence. In Colonial times the moose was called in Pennsylvania the Black Moose, to distinguish it from the Gray Moose or Wapiti [what we call the elk], but quite a few hunters gave it the quaint name of “Original.” An aged Indian hunter, Tahment Swasen, who wasadmired by the gifted Thoreau, and who hunted in Pennsylvania, has explained the meaning of the name. The moose was supposed to be the ancestor or “daddy” of the entire deer tribe. Hence, was the original representative of the species on earth. This was proved, he said, by the fact that the Moose is found pretty much all over the Northern hemispheres of the world. De Kay says that Moose is a corruption of the Indian word mosee or “wood-eater.” Dr. Schoepf, the distinguished German traveler, mentions the Black Moose as occurring in Northampton County in 1783.It was also reported to him as being prevalent on the Alleghenies between what is now Altoona and Pittsburg [sic]. West of Fort Pitt it had lately been extirpated. H. Hollister, in his fascinating “History of the Lackawanna Valley,” mentions Black Moose being killed in the Capouse Meadows near the present city of Scranton during the last decade of the eighteenth century. James Hennessy, a farmer residing at the Tamarack Swamp in Northern Clinton County, dug up several pairs of fresh looking moose antlers on his property about fifty years ago, showing that the animals had ranged through that region in comparatively recent times.

A curious Indian legend recounted in “More Pennsylvania Mountain Stories,” by the author of these pages, explains the existence of Moose in the Tamarack Swamp. Before the white men came to Pennsylvania Black Moose doubtless bred in the State. They were found all over its extent, judging from accounts of reliable persons. They had their favorite paths, most of which led in a southwesterly direction across the State. They had favorite streams for bathing, like the elk. The Moshannon Creek in Centre County was formerly called Moose-hanne, or Moose stream. In its deep pools they were said by the Indians to perform religious rites when the moon was crescent shaped. There are two Moose Creeks in Clearfield County. They crossed the Delaware River from New York State, near, where the town of Narrowsburg now stands, for after the native stock had been destroyed they came as migrants from the North. “Driven thither by cold, dogs, or wolves,” says Rhoads. From the Delaware they traveled in a westerly direction to Moosic Lake, in Lackawanna County. Great numbers were killed by the first settlers on the slopes of Mount Cobb, or Moosic Mountain,—the “Imperial Moosic” of the poet Caleb Earl Wright. From that region they ventured further South through the Wind Gap in the Blue Mountains, where they were slaughtered by the German pioneers in Northampton and Lehigh Counties.

The name “Original” is remembered by old people along the West Branch of the Susquehanna in Clinton County, showing that they must have crossed that river in the vicinity of Renovo to Keating on their way to their favorite Moshannon. Mr. Rhoads says, that Bartram in his “Miscellanies” refers to the Wapiti as the Original. But it was the name mostly given to the Black Moose. Dr. Merriam, in his splendid “Quadrupeds of the Adirondacks,” a book which no nature lover or sportsman can afford to be without, states that the last Moose in the Adirondacks was killed in 1861. The height of this last specimen, which was a female, was seven feet at the hump and weighed 800 pounds. Among the last men in New York to kill a moose was Hon. Horatio Seymour, Governor of the State, and the antlers were much admired for many years at his home at Deerfield in Oneida County.

Verplanck Colvin in his report on the Adirondack Wilderness in New York, transmitted to the Legislature in April, 1874, says: “As a matter of zoological and general interest, I may mention that in a few of the most remote portions of the wilderness we have met with indications of the Moose, which, to some of the guides seemed unmistakable. This gigantic deer is, however, almost extinct in the Adirondacks, and I would suggest that it be made, in future, unlawful to kill or destroy the animal at any season.”

Those who have heard the old-timers speak of the Original in Pennsylvania say that it was a creature of appalling size. It stood close to eight feet at the hump, and bulls often weighed a ton. The spread of the horns was tremendous, but the creatures handled these appendages with great dexterity (pg. 36-39).

One should not assume that moose were just creatures of the boreal and mixed northern forests.

At one time they were found quite far south in Europe.  The only relict population in Central Europe is the population that is found in the southern Czech Republic, but they were once found throughout central Europe, including much of Germany into the Low Countries.

It would make sense that their original range in North America would have been much more southerly than it currently is. It would simply be fitting with what was once exhibited with moose in Europe.

Caribou were once found throughout Northern New England, as well as northern parts of New York State.  They were also found on Michigan’s UP and in northern Wisconsin and Minnesota. Today, their range in the Lower 48 is restricted to the Selkirk Mountains of Idaho and Washington State.

Moose, like the caribou, could have lived south of where they currently range.

Shoemaker’s work is full of these little anecdotes that challenge conventional notions about historical biogeography.

One should take his work with a grain of salt, but one should realize that he spent a lot of time talking to old pioners in the mountains of Pennsyvlania– and not all of them were the grandaddies of all liars. Some of them certainly were, but others could have been telling accurate stories– well, accurate enough when one understands how limited their zoological knowledge actually was.

If moose lived this far south, they probably never will again.  Before Europeans came to North America, white-tailed deer were not the dominant deer species in Eastern North America. That title would go to the wapiti or “elk.”

Both moose and wapiti evolved in Eurasia and came across from the Bering Land Bridge into North America. Because they had to come so far north to enter North America, they spent generations evolving in environments without temperate parasites.  White-tailed deer were always living in these parasite ridden enviroments, and they carry a lot of deer-specific parasites now.

Wapiti eventually developed a resistance to the parasites, but moose never did.  Moose cannot survive very well in habitats that are full of white-tailed deer.

That area in Pennsylvania is now full of white-tailed deer. White-tailed deer now exist in numbers that far exceed their original numbers, and that means that moose will never be able to thrive in the region.
