Evolution doesn't stop, nothing alive now or in the past was an inherent endpoint. So this shouldn't come as that big of a surprise:
But the origin of this domestication remains stubbornly mysterious. Researchers analyzed the genomes of wolves from three likely sites of domestication (the Middle East, Asia and eastern Europe), and found that modern dogs were not more closely related to any of the three. In fact, it seems that the closest wolf ancestors of today's dogs may have gone extinct, leaving no wild descendants.
This is being widely reported in traditional media as "Dogs did not descend from wolves." Technically true, wolves are a modern species. But if you saw a member of the species dogs did descend from, calling it a wolf would probably be pretty damn descriptive.
"The dogs all form one group, and the wolves all form one group, and there's no wolf that these dogs are more closely related to of the three that we sampled," said study researcher John Novembre.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

        A hybrid of red wolves and coyotes. Going over to water a neighbors plants I noted some tracks which I think were a

        which for a dog(3 1/2"), coyote (2 1/2") or fox (1 1/2"is too much of a span for that gait.

        As for the free solo I think the training required to be able to mantle up a sheer face lifting your body with the fingers of one hand verges on a no longer completely human mutation capable of mating only with similar animals adapted for high levels of adrenaline.

      the areas like siberia where the samoyed people and their dogs were found - isolated - NO "dogs" except the sammy who had been with the people forever.  that these are considered to be a domesticated "white wolf" - the ones who adapted to living with humans for survival belies the latest "discoveries.

      yes, i'd agree, checking a chihuahua against wolf dna might show far enough evolutionary changes that the link is lost - but check out the samoyed.  there WERE no "wild dogs" to cross with the wolf - just the artic wolves.  that dna is going to paint a very different picture from the cocker spaniel andother breeds.

  •  One of the perils of imprecise language (20+ / 0-)

    It has become standard usage in the science vernacular to say that one modern day species "descended" from another modern day species, when what is really meant is that the two species have a common ancestor, which is probably not on the scene today.

    So, we get creationist knuckleheads yammering about modern day humans "descending" from modern day apes, monkeys or chimpanzees, and how they want no part of it. And nobody seems to recognize that they're actually spouting gibberish, along the lines of "I'm descended from my fourth cousin Amy." No, what is really meant is that tracing back your family tree a sufficient number of generations, you and cousin Amy share a progenitor, a common ancestor, who isn't around anymore: great-great-great-grandmother Eleanor.

    You and your present-day distant cousin aren't "descended" from each other, you share a common ancestor. Today's dogs and wolves aren't "descended" from each other; they have a common ancestor, which is probably not on the scene anymore. It's clunky to say it that way, and clangs on the ear for our present day discussions, but it clears up a whole lot of misunderstandings (both inadvertent and intentional) when we use the right language.

  •  Attacks on falsifiability (8+ / 0-)

    basically allow the bible to be a source of scientific insight.

      ....explain how the world works.

      If the model is valid, then it will not only explain all* the currently observed data, it will also make testable predictions about data that hasn't been observed yet. For example, Einstein's 1915 theory of General Relativity not only accounted for all the currently observed data, it also made predictions about data from experiments that hadn't been performed yet.  In 1919 Arthur Eddington performed an experiment on the gravitational bending of light. Einstein's theory gave the most accurate prediction of Eddington's data.

      *Relevant to the problem domain of the model. You wouldn't use General Relativity to explain data collected from observing the behavior of bacteria.

      Falsifiability plays a crucial role in the advancement and evolution of science. In 1887 Albert Michelson and Edward Morley tested the theory of luminiferous aether; but the theory failed to accurately predict the observed data. This falsification led to Einstein's theory of Special Relativity.

  •  The link on falsifiability is great - (15+ / 0-)

    particularly the comments to the article.  Author Carroll is proposing the retirement of falsifiability on the grounds that some parts of physics, like string theory, have issues with being tested/falsified.  But as I am a strong proponent of the idea of falsification, I was greatly heartened by the many comments taking issue with the author's proposal.

    I have been teaching a course on Science and Religion for over 15 years at a small liberal arts college, and falsification is a great point of comparison between the two.  And of course, the original point of Popper on the need for falsification was that it was an appropriate way to exclude religious-only thinking from science.

    Also, at the end of the article, there are about a dozen other articles referenced for other scientist's ideas of what should be retired in science.  A couple of my favorites (for retirement): IQ and the idea that scientists should just stick to science...

        Phylogenetic systematics of the North American fossil Caninae (Carnivora: Canidae).
        By: Tedford, Richard H.; Wang, Xiaoming; Taylor, Beryl E.
        Bulletin of the American Museum of Natural History  Volume: 325   Pages: 1-218   Published: 2009

        states that Canis lupus invaded North America from Eurasia about 800,000 years ago (or more) and spreading to mid-latitudes by 100,000 years ago.

        So compared to a lot of other large mammals they are fairly recently arrived in North America.  However they have been here over an order of magnitude longer than humans.

        •  Interesting. (3+ / 0-)

          I see on the wikipedia page that Canis lupus is thought to have colonized North America during the late Rancholabrean era, which was between 240,000 and 11,000 years ago, which would match with ban nock's comment. But the reference for that is a bit older (Mech, L. David; Boitani, Luigi (2003). Wolves: Behaviour, Ecology and Conservation. University of Chicago Press. ISBN 0-226-51696-2.) It also says that the Gray Wolf's most likely ancestor is Canis lepophagus, from North America. I guess there was a gap in between where maybe the ancestors of the Gray Wolf moved to Eurasia, and then some eventually came back to North America.

            •  I've pasted in the abstract of the paper I cited (3+ / 0-)

              I don't have enough knowledge of the area to comment on different arguments.

              I will comment that both Mech and Geist are ecologists and wildlife biologists.  The authors of the paper I cited are paleontologists and systematists.  In other words evolutionary history is their area of expertise.  Not to say that automatically makes them right but all else being equal I'm inclined to give them the edge on being more likely to be correct.

              The canid subfamily Caninae includes all the living canids and their most recent fossil relatives. Their sister taxon is the Borophaginae with which they share an important modification of the lower carnassial, namely the presence of a bicuspid talonid, which gives this tooth an additional function in mastication. Contributing to this function is the enlargement of the posterolingual cingulum of M1 and development of a hypocone. The Caninae diverged from the Borophaginae in the narrowing and elongation of the premolars separated by diastemata and placed in a shallow ramus and narrow muzzle. These latter features allow the Caninae to be recognized in the fossil record as early as the beginning of the Oligocene (34 Ma) and constitute evidence that they represent a monophyletic group. In striking contrast to the history of the Borophaginae, the Caninae remain confined to a closely similar group of fox-sized species (Leptocyon spp.) throughout the Oligocene and showing very limited cladogenesis into the end of the medial Miocene (12 Ma), a span that saw marked adaptive divergence in the Borophaginae and the origin of all its major clades. By 12 Ma (beginning of the Clarendonian Land Mammal age) few fox-sized borophagines remained and most of those held hypocarnivorus adaptations. At that point the Vulpini appear both as mesocarnivores (Vulpes spp.) and hypocarnivores (Metalopex spp.) reproducing, on a much smaller scale, the range of adaptations shown in the initial radiation of the Borophaginae. By the end of the Clarendonian (9 Ma) the first members of the tribe Canini appear. Initially this group was represented by the genus Eucyon, largely by a single widespread North American species E. davisi. Our cladistic analysis predicts that the roots of the South American clade subtribe Cerdocyonina, sister taxon to E. davisi and Canis species (together, subtribe Canina), must also have been present, but taxa representing this group do not appear in the North America record until the earliest Pliocene (latest Hemphillian, 5 Ma). Species of three genera (Cerdocyon, Chrysocyon, and possibly Theriodictis), now confined to South America, appear in the fossil record of the southern United States and northern Mexico prior to and just after the opening of the Panamanian Isthmus (ca. 3 Ma), indicating that important cladogenesis within the South American clade took place in North America. Species of Eucyon make their appearance in the Old World in the late Miocene, and E. davisi has a Pliocene record in Asia. Species of this genus undergo a modest adaptive radiation in Eurasia during the Pliocene. In the late Miocene and early Pliocene two species of Canis appear in North America (C. ferox and C. lepophagus), representing the initial cladogenesis within the genus. These animals are all coyote-sized and represent a broadening of body size range within a mesocarnivorous dental adaptation. Toward the end of the Pliocene and into the Pleistocene in North America a curious and rare group of jackal-like species (C. thooides, C. feneus, and C. cedazoensis) seem to form an endemic clade arising near C lepophagus. These taxa are dentally similar to jackals, especially C aureus, but share no synapomorphies with them. The early cladogenesis of Canis in the Pliocene of North America produced a somewhat larger form, C. edwardii, that appears in the late Blancan at ca. 3 Ma. It also seems to have a sister relationship with C. lepophagus and with the coyote C. latrans, which appears much later in the record (late Irvingtonian) and quickly becomes distributed across the United States. The golden jackal (C. aureus) shares synapomorphies with the coyote and C. edwardii but does not appear in the fossil record until the early Pleistocene of North Africa. Canis edwardii is extinct by the end of the Irvingtonian. Large wolflike species of Canis seem to be the products of evolution in Eurasia. They appear early in the North American record as immigrants of the crown group of Canis that augment the essentially stem group native species of the New World. The first of these is Canis armbrusteri, which appears early in the Irvingtonian, initially in the Southwest but later in the eastern United States where it survived into the early Rancholabrean of Florida. This is a large wolf, a sister taxon of C. lupus, whose appearance early in the Pleistocene predates the earliest midcontinent occurrence of C. lupus by nearly 1 m.y. In the New World C. armbrusteri gave rise to the native dire-wolf (C. dirus), as evidenced by intergrading morphologies of late Irvingtonian examples that show the transformation to the more hypercarnivorous giant form. The earliest evidence of C. dirus is in the midcontinent and it appears to have displaced C. armbrusteri into the eastern part of the continent while it expanded westward and particularly southward into South America during the late Pleistocene. Canis lupus itself does not appear in midlatitude North America until the late Rancholabrean (0.1 Ma, last glacial cycle), although it was a resident of Arctic North America since the mid-Pleistocene (ca. 0.8 Ma). North America has a limited record of canine diversity during the Pleistocene. Most clades of vulpines and canines that reached the Old World during that span underwent significant cladogenesis so that the canid fauna of Eurasia was always more diverse than that of the New World. From time to time waifs from the Old World centers of origin wandered south into midcontinent North America to briefly enrich the fossil record: Xenocyon spp. in the late Irvingtonian; Cuon alpinus and Canis lupus in the late Rancholabrean, along with the living fox species Vulpes vulpes (late Rancholabrean) and perhaps the swift-fox earlier in the Pleistocene. The center of evolution of the Caninae thus shifted to Eurasia and to South America when avenues of dispersal to those continents were available at the end of the Cenozoic. Because of the diversity of Old World forms that became resident in North America, our analysis of the New World fauna has been expanded to include relevant Old World taxa and to present a broader phylogenetic reconstruction than could be offered only on the basis of strictly New World evidence. This expanded view brings in a greater diversity or morphology, which allows LIS to better separate homoplasy from true homology. We have considered only Old World taxa that are represented by the most complete material so that missing data are kept to a minimum in our analysis. This still affords sufficient taxa so that the major structure of the phylogeny of Canis can be discerned. Our cladistic analysis Found two robustly recognized crown clades within Canis: the mesocarnivorous lupus clade, and the hypercarnivorous Xenocyon clade. The first contains the wolf, C. lupus, and its sister taxon C. armbrusteri + C. dirus, with the latter showing some dental features related to hypercarnivory as an autapomorphy. The Chinese late Pliocene wolf C chihliensis appears to be a stern group in the Lupus clade and may be closely allied to C. armbrusteri. The Xenocyon clade is also Eurasian in origin and is marked by character reversals to states primitive within Canis. Its earliest record is in the medial Pliocene of eastern Asia (Xenocyon dubius), after which it dispersed to western Eurasia in the early Pleistocene (X. lycaonoides). In the Pleistocene Xenocyon achieved a Holarctic distribution including midlatitide North America (X. texanus and X. lycaonoides). During this episode of expansion the sister taxa Cuon and Lycaon arose in Eurasia and Africa, respectively, most likely from isolated Xenocyon Populations. In the latest Pleistocene Cuon alpinus expanded its range into the middle latitudes of the New World. A number of Pliocene and Pleistocene wolf and coyote-sized Eurasian Canis species (C. arnensis, C. etruscus, C. palmidens, C. mosbachensis, and C. variabilis) were included in our cladistic analysis, but the relationships of those forms were difficult to resolve beyond their paraphyletic relationship to the crown clade.

                I wish the "Rancholabrean" especially the "late Rancholabrean" were a little more specific.

                I think by saying lupus didn't come to N America until recently that's the time period they (Mech, Geist) mean, not the arctic at .8 Ma (maybe that means 80K years? 800K?) I have never heard of any controversy either, probably just different take on things rather than warring camps of scientists.

                Whatever things were like before they're likely to be very different looking forward into time. Yesterday I was up high with my kid with blowing snow wind etc., I remarked to him then that things might be different in his lifetime.

        Canis lupus colonized North America during the late Rancholabrean era.[
        The Rancholabrean North American Land Mammal Age on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from less than 240,000 years to 11,000 years BP

        canines mix and change and interbreed. I too have heard they originated here (lupus) became extinct, and were re established via the land bridge.

        Many mammals we consider native are actually very very recent arrivals. Griz, our elk, wolverine, etc. Somewhere I'm sure there is a list.

      Besides in our world there is no longer any such thing as safety, We all grew up knowing we were doomed and it was just a matter of time, so why not live life instead of invest in a belief in going to a better place after you die?

          Not to belittle the climber's effort too much, but the article does explain that he had made the climb several times with the protection of a rope before doing the free-solo climb.  In other words he had it wired.

            What I always used to wonder about was what happens when you forget a move and have to back down from someplace that you had committed to with stretches and leaping grabs. Then I watched some of these people climbing up a shear face or an overhang upside down, hanging by their toes and decided I was just looking at an alternative reality.

            As for  Alex Honnold's the kid who did this you would think that ego wise after you solo half dome you could rest on your laurels, I guess it must be more than that . The number of free solo climbers who have died is starting to rival Everest.

            Jimmy Jewell, 31 October 1987, fell to his death from Poor Man's Peuterey (Severe) at Tremadog, North Wales. Ironically he was using the route as a shortcut from a local pub to his climbing club hut. The route was well below his usual grade and capability.

          indeed many approaches or descents require some soloing. Of all the people I know who soloed at 5.10 or higher with regularity only one took the plunge while soloing, and I believe his problem was more late afternoon thundershowers than the climb itself (sentinel)

  •  When ever I run into a rabid creationist here in (11+ / 0-)

    Texas--the kind of person who swears that God created every kind of being there now is on the earth during that busy first week--I simply ask "Then where did the Chinese Crested Dog come from? Where did the Great Dane come from? Where did the Pekinese and the Greyhound come from?"

    Because the answer, of course, is that we created them, using the same process that nature uses. We look for random genetic mutations--large size, small size, a certain type of coat, a certain type of color, etc.-- and we select for those mutations that please us. The only difference is that nature selects for those mutations that tend to help an organism stay alive long enough in a certain, specific environment  to reproduce and pass on that mutation. Since environments change, nature's selections change.

    The Chihuahua and the Irish Wolfhound...those are the proof of the mechanism of evolution.

  •  If I was going to pick an idea in science .. (10+ / 0-)

    that needed retirement it would certainly not be falsifiability! I fully realize that historical science cannot be easily falsified (although it can be altered by new geological or paleontological evidence.)  Still some standard is needed in order to define true science from fantasy.  Otherwise spoon-bending, alien abduction, the Loch Ness monster, Bigfoot, etc. are ideas that are as good as gravity, relativity and natural selection.

    Actually, Popper was not the first to use falsifiability as a prerequisite for a scientific question.  John Stewart Mill is credited with that invention.  Popper formalized it in more detail, if I understand right.

    No wonder theoretical physics is in such a muddle these days!  I guess that we all must be holograms and that matter itself must not exist (it is a sort of illusion in reality, as only the strong forces hold things together in a way that makes matter seem solid, most being empty space - still one would be a fool to run into a brick wall thinking that you could pass through it.)

    It seems to me that dispensing with falsifiability is a misinterpretation of Post-Modernist thought in which all ideas are equally worthy of investigation. In my opinion, in that way lies madness.  Even if we cannot always test a theory directly at the present time, falsifiability remains a worthwhile and indeed, necessary, goal.

    I expected the "diamond blue lava" link to be talking about a planet or protostar thousands of light-years away.  Instead, it's right here on this planet, and the pictures are spectacular.  And it's because of sulfur!

    I loved that article on scientific ideas which should be discarded.  Cause and effect?  Quantum jumps?  And of course, falsifiability.  Great reading that causes is associated with serious thinking.

      science.

      Today's limitations preserve tomorrow's opportunities.  Who knows? With enough shoulders of enough giants, perhaps every real phenomenon is falsifiable.

      I agree 100% with the expressed concerns about turning science into faith and scientists into priests and prophets.

      If some things remain -- even temporarily -- beyond the reach of science, then so be it.  Science without rigor becomes a glorified creationist museum.

    Miners carry between 176 and 220 pounds of sulfur chunks per trip and sell the pieces for around 2.5 cents per pound. Yahoo reports they average two loads every 24 hours, thereby doubling their salaries amid sulfurous flames that can reach 16 feet high
    220 lb x 2 loads/day x 2.5 cents/lb = $11 dollars a day

    That is insane.

    is in order. Kawah Ijen is not "spewing blue lava." There is a sulfur concentrating operation in an area of high degassing inside the crater. The fumaroles have been utilized for sulfur collection for many years. The activity is actually protected by the government because so many people make their living by collecting the solidified sulfur, packing it down the volcano and selling it to a local sugar refinery.

    The pipes running up the rocks allow the sulfur fumes to condense into liquid sulfur, which flows both out of the pipes and from cracks in the rocks. The sulfur has been ignited off and on over the years, I suspect because it makes an otherworldly sight for tourists.

    The lake in Ijen's crater is one of the most acidic bodies of water on Earth, with a pH of 0.5.

    As they breathe the acrid fumes using little or no protection, workers expose themselves to erosion of their teeth and destruction of their lungs.

    YouTube has many videos of the mining operation and acid lake.
