    I believe that this "news" has been known for nearly all of the 20th century. I'm not sure where the article gets off talking about:
    recently proposed trees of mammalian evolution indicating that primates (human, chimpanzee, baboon) are more closely related to rodents (mouse, rat) than to carnivores (cat, dog) or artiodactyls (cow, pig).

      According to the Tree of Life Web Project [tolweb.org], all the animals mentioned (rodents, felines, humans) belong to the infraclass Eutheria [tolweb.org](placental mammals).

      If you look closely at the tree, you will see that the Tree of Life does indeed have order Rodentia closer to the order Primates. I recall learning this in high-school biology, also.

      Yes this does seem to be a bit of old news.

        Tha part of the tree you refer to is unresolved , a polytomy.

        What is important in a phylogenetic tree is branching order. When the branching order is uncertain or ambiguous, a polytomy is put in place. The placement of the branches in a polytomy are usually arbitrary, or in alphabetical order.

        From the tree, you can tell that primates are most closely related to tree shrews, and that the group (primates + tree shrews) in turn is most closely related to bats and colugos.
    • That same bit of text jumped out at me as well. This article is hyped as saying we're closer to rats then anything else, but really, it's still just saying that primates (human, chimpanzee, baboon) are closer to rats then we are to cats, dogs, cows, and pigs.
      Thanks, I couldn't have figured that myself. I suppose the follow up article is that cats, dogs, cows and pigs are closer to rats then they are to fish.
      What a non story.

      The interesting point is that junk DNA has some still-unknown function, so the disappointing figure of 30,000 genes isn't as bad as we feared.

      Regarding mice-etc, primates began as shrews who climbed trees and developed their eyesight, mammalian carnivores like cats evolved much later from the shrews that stayed on the ground.

    The blurb from "fygment" must have been written by a mouse, as there's hardly a complete sentence in that jumble of incoherent fragments. I find this situation has become all too common on slashdot recently. If you can't be bothered to write a cohesive paragraph with complete sentences, then stop submitting to slashdot. You may not think it's important, but when you write things that will be read by a number of people it is essential. Use whatever style you want in email or IM but if you're going to submit something for public consumption you should take the time to learn how to use English, otherwise you just come off looking like a rambling idiot.

    • Could be worse. I work with people who can't conjugate verbs, use the wrong 'to' and just can't speak English. They send countless internal documents based on previous mail messages where they cut and paste the same piss-poor spelling and grammar.
      Example:

      They make ol' fygments (sic) look like a Pulitzer.

        Bad example. In defense of "effective-enough communications", I'd like to point out that the error you highlighted didn't detract from my understanding of the message.

        I can understand how someone in a hurry (or without a college-level education) could add the "to" and put "look" in the infinitive. In fact, if I go to look at the sentence long enough, it looks just fine!
    • I don't play Grammarian very often, but you've got a valid (if offtopic) point. But you really don't go far enough:

      Use whatever style you want in email or IM...

      I disagree with this premise, because "practice makes perfect" only works if you're practicing perfectly (you can thank my daughter's piano teacher for that one). I don't care if it's email, IM, or a sticky-note on your monitor... what's it going to hurt to do it right?

    In fact, they are the protrusions into our dimension of hyper-intellegent pan-dimensional beings. These beings are in fact responsible for the creation of the Earth."

    You can browse the tree of life [tolweb.org] starting from its root [tolweb.org]. If we descend to mammals [tolweb.org], we'll see that lines that lead to rodents, primates and carnivors all start in the same point. Of course, it's unlikely that several branches start in the same point of evolution. It's more likely that the tree divides into two branches and then divides again.

    Perhaps this research will allow to make some adjustments to the tree. However, there are already interesting facts in the current version. For example, bats are closer to primates than most other mammals. On the other hand, armadillos must have branched very early, although they did it after opossums.

    The mammalian line forks into one group that goes on to split into felines and canines, and another that further splits into rodents and primates.

    Next this poster will post an article that says Birds are closer to reptiles than to humans. I'm no biologist but I can tell when someone tries to pass an encyclopaedia fact for a breakthrough news.

    As an owner of pet rats, one thing I've noticed is their sometimes disturbing similarities to humans in habit.

    At one point, my two female rats were constantly squeeking and making noise at night. No problem, nocturnal animals, they're just more active in the dark. However, I also noticed that oftimes when I turned on the lights, that the rodents were "cleaning each other" in a position often labelled as a number just shy of seventy.
    Now, at first I dismissed this, thinking that I was imagining things. However, after talking to several rat owners and a few petshops, I have garnered that this can indeed be more than simply a hygienic practice.

    Afterwards, I'd throw things at the cage when they made too much noise to shut them up. At least until one morning after I found they'd dragged in the shirt I'd thrown and perforated it for nesting material. I liked that shirt too.

    Now, I've got two new rats. They don't often exhibit the same behavior as the old ones, but sometimes they will. I'm considering breeding one of them (baby rodents being quite cute 'n all), and I wonder if this will change their behavior towards each other after the babies have grown (and one rat has had an encounter of the opposite sex as opposed to the same). And of course, if I got enough rats perhaps I could make some of this [halfbakery.com]
