Orangutans Helping Discover Our Evolution

Posted by michael on from the hints-from-heloise dept.

DiZASTiX writes "An article at MSNBC says, Orangutans share distinct "tricks of the trade" for feeding, nesting and communicating. Scientists say these behaviors represent humanlike culture. The discovery offers tantalizing new clues about our own evolution. By documenting these behaviors scientists are finding more and more information on our past. We may be more related to monkeys than we think."

  3. Enabling Cultural Evolution by airuck · · Score: 4, Interesting

    The Science article makes the case that observed orangutan behavior is more closely correlated with geographic location and opportunities for direct transfer of skills than to habitat (independent innovation). The authors then speculate that the common ancestor of all the great apes could have had this ability, and therefore, the beginnings of hominid culture could extend back 14 million years.

    I find it interesting to speculate that something in our neural circuitry enabled early primates to learn from each other. I wonder if anyone within the human brain project is considering this area of research.

  4. Your missing the point by Cy+Guy · · Score: 5, Interesting

    The fact that they have these types of social interactions is not new, what is new is that distinct geographically isolated populations have different ways of accomplishing the same thing.

    NPR ran a nice piece on this today, and used the example of a fruit which one population eats by getting it open with a stick (a picture is included in the MSNBC article). A neighboring population seperated by a river, either eats the fruit by bashing it on rocks (much more inneficient) or by ignoring it as too hard to bother with. i.e. one population has learned to use a tool for specific task and has passed that information on the other Orangs in the community. Its the passing on of this knowledge, and the fact that it couldn't be passed to the neighboring population that makes this 'culture'.

    From a SlashDot perspective, one could speculate that on the one side of the river, the solution for eating the fruit has been open sourced. But on the other side of the river, the solution was either never discovered, or if it was found, was closed source and died with its dicoverer(s).

    Other examples given are a Kiss-Squeek gesture & sound, and "snag riding" a demonstration of male virility of breaking off trees and holding on to them while they fall, jumping off before they hit the ground (Orang candidates for the Darwin Awards perhaps?).

      Well, then you have un-cultured cats, as we always suspected. :) I wonder at the tendency of science to quantumize everything. Why does a species have to intelligent or not, be cultured or not, have consciousness or not? I suspect it's more analog, from none to a little to some more to a lot. Unless they are cats. Then all bets are off.

    2. Re:man, that's a low standard by hal9000 · · Score: 2, Interesting

      It's not only learning that the orangutans have shown here. They also displayed long term memory, the ability to recognize the advantages of their actions (e.g. tools used for opening a fruit husk, arbitrary male displays that attract females). Many creatures do this sort of thing, but it's generally believed to be hard-wired. That behavior varies geographically in orangutans clearly shows that this is evolution on the memetic, software level -- a phenomenon that humans have long believed was our own.

      What the orangutans also show is a desire to provide their fellows with these memes (i.e. to teach). That these memes exist, not in terms of individual orangutans, but in terms of *groups* of orangutans, in which individuals come and go, is what makes this a display of culture. In essence, orangutans have meme pools.

      It's funny, because I just finished Chris Lavers' Why Elephants Have Big Ears: Patterns of Life on Earth and I was wondering about a differe dichotomy. Paleontologists are obsessed with the question of whether dinosaurs were warm-blooded or cold-blooded. I couldn't help but think to myself, "Why does it have to be one or the other? Why not in some middle ground, where they regulate their temperature to a limited extent?"

  6. Must everything be about Open Source? by bill_mcgonigle · · Score: 2

    From a SlashDot perspective...

    You're right about the topical matter, but I just wanted to point out that it's OK to talk about science by itself, without trying to find an analogy to benefit the free software movement. Slashdot is supposed to be about nerdy stuff, not just Open Source software, however fun and nerdy that is.

    Back on topic, the NPR story refers to apes as our 'ancestors', which of course they aren't, so be careful, and remember that convergent evolution is a common pattern in nature, so the anthropological benefit of this research still has some proving to do.

    Of course, ignore my .sig for this particular comment. :)

      the NPR story refers to apes as our 'ancestors', which of course they aren't,

      I think you are misinterpretting the article. The quote you refer to "the finding appears to whittle away a little more of the divide between humans and their ape ancestors." the way I interpret it is referring to the common ancestors of both the Great Apes and Modern Humans.

      In the case of orangs, they mention that they split off from our common ancestors 14 Million years (which I think was earlier than Gorillas and much earlier than Chimpanzees and Bonobos - elsewhere I've seen 8, 6, & 5.5 Million years ago as the approximation of these splits). By finding that all living descendants of these common ancestors share a common characteristic, they are inferring that the common ancestor(s) also shared the characteristic (in this case - culture). Of course there is no way of knowing whether this is true or whether each of the living species developed it independently at some point in their evolution since the split.

  7. Culture dominant by airuck · · Score: 2

    Precisely, it has now been demonstrated in all great apes that culture can dominate over independent innovation (not that it always dominates). Something in our evolutionary line facilitated the jump from individual innovation to group learning (culture), something that preceded language and human brain structure.
