Scientists Close To Solving the Mystery of Where Dogs Came From 167

sciencehabit writes: For years researchers have argued over where and when dogs arose. Some say Europe, some say Asia. Some say 15,000 years ago, some say more than 30,000 years ago. Now an unprecedented collaboration of archaeologists and geneticists from around the world is attempting to solve the mystery once and for all. They're analyzing thousands of bones, employing new technologies, and trying to put aside years of bad blood and bruised egos. If the effort succeeds, the former competitors will uncover the history of man's oldest friend — and solve one of the greatest mysteries of domestication.

            Whilst technically true, your statement is also misleading (if you meant to imply foxes are more closely related to cats than they are to dogs). Wolves, jackals, dogs and foxes are all Canids [wikipedia.org]. Foxes are also more closely related to seals, otters, skunks, weasels, red pandas, bears and walruses than they are to cats (the Caniformia [wikipedia.org] suborder contains all these, felines are in a different suborder).

            You may be thinking of Hyenas, which are more closely related to cats than dogs.

            • The modern taxinomy might call them canids, but they are not related in any way to them, besides being mamals.
              By coevolution they look like dogs, but they aren't. Ofc they are not felidae either.

        • That was a pretty interesting study, and does show that the underlying behaviors of canids and humans have some degree of compatibility and overlap, and it does not require a large amount of breeding to produce domesticated canids. The fox experiments (I think they were done in Russia) demonstrate that the domestication of wolf progenitor populations into dogs was probably fairly rapid, which also raises the likelihood (strongly hinted it in the molecular data) that there were multiple wolf domestication ev

      • by pubwvj ( 1045960 )

        The evidence for multiple domestications is overwhelmingly strong. Denial of it is like climate change denial. There may always be someone with their pet unified domestication theory but it's simply wrong.

    • I think there is enough evidence to suggest that domestication happened independently in at least three different places: Eurasia, Australia and America. Why are they trying to narrow it to a single place?

      Since the dog is supposed to be the first animal domesticated, maybe we're overlooking something unique. Maybe it's not just the dogs that could get along well with humans had a greater chance of surviving, but also that humans who could get along well with dogs also had a greater chance of surviving. There's no reason why natural selection wouldn't prefer such an evolutionary preference in both humans and dogs. It's not like humans are immune to the effects of natural selection.

      • I'd say that's a good point, and probably not necessarily overlooked. In Guns, Germs, and Steel the author makes a point about animal domestication as a precursor for dominant cultures. He had an amusing example of how different history would have gone for Africans if rhinos could've been domesticated into cavalry. In tribal conflict a pack of loyal dogs would be a huge boon to those that had them. Dogs also tend to be very protective of human children in my anecdotal experience.
        • Dogs are instinctively protective of babies and children. Every family with kids should have a big mutt to prevent child abuse.

          Dogs and humans are also the only animals known that prefer the other species company to their own species.

  • by pubwvj ( 1045960 ) on Friday April 17, 2015 @09:19AM (#49493147)

    There is a huge amount of evidence that domestication did not happen once or in one place but many times in many places around the world. This evidence points back as far as about 135,000 years and as close as about 15,000 years for each of these events in time where wolves domesticated humans. It is speculated that wolves did this for two reasons: fire and thumbs for scratching.

    It is not surprising that there would be multiple domestications. A human plus a wolf are far more powerful at defense and offense, at hunting and guarding than either species alone. Our social structures are very parallel and our physical abilities complement each other.

      If you read the article (I know, I know), you would have seen that the evidence for multiple domestication events can be misleading (as was first believed in pigs, and then disproved). This research will hopefully get to the bottom of it.
      • by pubwvj ( 1045960 )

        Yes, I did read the article and still see strong evidence and logic for the multiple domestication. For example, some strong domestication results are within the 15K BP timeframe but people also took domestic dogs with them to Australia which is much greater than that frame. It's complex. I doubt this will solve it.

        • The dingo only originated about 5000 years ago (a dog that hopped on a boat from Asia). It's a dog gone wild, nothing to do with the original domestication/s.
          • by pubwvj ( 1045960 )

            Yes, that's the point but your date is off. The immigration to Australia included dingos but was further back.

    • Now, this is a theory, a thesis. It seems plausible, but you haven't advanced any data to see if it is indeed true.

      This is precisely what these folks are trying to do.

    Thus it would be a surprise if dog domestication happened only once.

        He does, and so do the Russians that domesticated foxes. His point is that if foxes domesticate so rapidly, wolves likely do as well.

        • Ofc they do, you need perhaps ten to twelve generations.

          However foxes become more dog like and lose their 'foxyness', at least that happened in Russia (I assume you refer to those 'blue foxes').

          • Exactly, and wolves lost their 'wolveness' and become what we call today dogs.

            • Erm, I don't see much difference between a wolf and a dog.
              The foxes in russia, became like dogs, too. That us what I mean they lost their foxyness ... a dog and a wolf are extremely similar, a domesticated fox and a ferral fox are not, domesticated foxes even bark like dogs.

    • The Russian experiment was extremely interesting for a number of reasons (the way floppy ears and lower brain capacity came with selecting against aggression for example. There is evidence to suggest that humans have self-domesticated over the years leaving us friendlier, cuter, and a bit dimmer than our distant ancestors; but I digress), but it's hard to see how it has much to do with the original domestication of the dog (you need cages and scientists and 50 years of a completely useless animal before you
      • Well, the standing hypothesis for domestication is that it wasn't really conscious, it just happened to be beneficial for both species - but for wolves first. Presumably they started by scavenging on edible remains left in the vicinity of human camps. The wolves that were less shy (so they approached the camps more) and exhibited less aggressiveness (so they would be chased away less) had an evolutionary advantage in that population, and so they bred for those traits. At some point that could have produced

      • by sshir ( 623215 )
        Simple - wolves are useful even in untamed form for defense: put one on a chain (well, rope) to growl at everybody approaching. Then allow captive ones to breed because capture is labor intensive. Then ask your kids who are playing with pups which one to keep (cute, friendly and cuddly of course) . ...and BAM! You've got a dog!
        • by dwye ( 1127395 )

          For a rather leisurely definition of BAM. It took around ten generations for the silver foxes, so I expect that it took a lot more generations for any wolf devoing to produce an acceptable "hound" that could be brought into the camp (after all, the hunters didn't KNOW how to do it before they tried).
