Ancient Krakens Making Self-Portraits? 135

First time accepted submitter Sanoj writes "Strange patterns of ichthyosaur bones have been found on an ancient deep-water seabed. One paleontologist has put forward the theory that these could have been the work of giant cephalopods who were eating the swimming dinosaurs and then arranging the vertebrae to resemble their own tentacles. Sound far-fetched? Apparently, the modern octopus also does this."

      I can also well imagine the intermediate steps in the evolution of such an adaptation.

      Every action does not need to have a direct evolutionary benefit. For example humans still have sex long after they have lost their reproductive ability.
      Some mammals play for no known reason. (Otters slide down into water just to run up and reepat the action.)

      Evolution does not optimize away unnecessary traits, only those that hinders reproduction. If making scarecrows doesn't prevent reproduction then it can occur as a mutation and stay.

        • Evopsych != natural selection. People really need to stop imagining that all the complex social shit has a demonstrable effect on allele composition and effect. Turning off geriatric sex drive would simply have to have a greater positive effect on reproduction than a negative one. Apparently it doesn't, and in fact no post-fertility behavior can impact genetic traits downstream except where it involves the care for the young (which by extension includes survivability).

            Group selection has been debunked. Only genes that reproduce have effects. The end.

            How do you account for the existence of non-breeding worker ants?

            • You're conflating kin selection with group selection. Beyond that, far as I'm concerned all the sterile offspring of an ant queen are for most intents and purposes extensions of the queen as a superorganism. The sterile workers don't have a separate existence, and are almost as much a part of the queen as another animal's armor or other biological adaptation.
              • by slim ( 1652 )

                But surely group selection is a weaker shade of the kin selection you're describing.

                In a close-knit family, the grandmother is as much a part of the child "as another animal's armour or other biological adaptation". Albeit, the child has inherited (some of) its genes from the grandmother, rather than vice versa.

                To look at it from a Selfish Gene perspective, the gene for "protect your grandchild" is increasing its own chances of being reproduced, by protecting a vessel that contains instances of itself.

      One speculation is that if the octopus litters the sea floor near its turf with octopi-like shapes, then predators will be "trained" to ignore octopi-like patterns, reducing or delaying the chance of attacks against it. The fake patterns keep "calling wolf".

      Delaying the predator would give the octopus time to react or drum up adrenaline (or it's equiv.) when a predator starts sniffing around. After attacking dummy rock patterns in the past, predators will take longer to investigate, if they even bother.

      "And, says McMenamin, there is one modern predator that does exactly this - the octopus. He suggests that the remains may indicate the existence of a giant octopus, similar to the Kraken of kegend."

      I'm surprised their spell-checker didn't catch the mis-spelling of "legend", but my point is that he's talking about the possible existence of an undiscovered animal. If it hasn't been discovered, it hasn't been given a name, so it makes sense to compare it to something people can relate to. An octopus has no bones, so I'm not sure what kind of fossils we'd be able to find from an ancient giant octopus. Maybe a giant beak?

Since I'm not a lawyer, I wouldn't feel the need to bu ultra-clear by expli

          • A simple reference to the "Kraken-like creature" would have sufficed. The author should have refrained from treating the creature as if it were an actual Kraken and instead continued to refer to it as "Kraken-like" to make it clear that it s an unknown type of creature that is similar to a Kraken. Just saying "the kraken" implies it is a Kraken, and not just something like one.

      No, I'm very pleased with his ability to communicate in a way that is perfectly understandable to normal people. I don't see you complaining about his using the term "octopus" which is just as much a nickname as "kraken" since neither of them is the scientific name of the animal in question.

      If someone discovers a large dinosaur that matches any of the various representations of dragons through the ages I'd have absolutely no problem with them calling by that name.

      To be less snarky about it: Communicating scientific information to the public and to the press is always a tricky endeavor and there is a balance to be found between speaking 90% latin and between super-sensationalism. I thought this article struck a decent balance between the two.

    This is why Science is so $#@%ing awesome. As Samuel Clemens put it best, “There is something fascinating about science. One gets such wholesale returns of conjecture out of such trifling investment of fact.” This will be a very tough hypothesis to sell, but the researcher says his evidence is ready to take on all skeptics.

    There are incredible stories waiting to be revealed in the fossil record and stories we have already uncovered. There's the footprints of Austrolopithecus, which were preserved in volcanic ash, large and small, male and female, close together as if they were huddling--perhaps the male had his arm around his mate, and the female's footprints lopsided as if she were carrying an infant. Imagine what it was like for them, walking fearfully across a landscape raining ash from a distant volcano... This story is drawn in this famous diorama [flickr.com].

    Or the Taung child [si.edu], whose skull bares the scars of an eagle attack. The child was carried away by a bird of prey. A story both fantastic and tragic at once.

    Or the stories of Homo erectus , who was the velociraptor of our human ancestors. She was a total badass, which is why I love this statue of her [flickr.com] at the Smithsonian Hall of Human Origins carrying a rotting caribou carcass across the Serengeti.

    Science has thousands of these stories that we have already discovered, and an infinite supply of them in store for us if we keep exploring. Knowing this, I simply don't understand how people can be so impressed with a book covering a few hundred years of human history and consider it sacred. The sacred is all around us, written in the natural world waiting for us to read it.
