Robots 'Evolve' Altruism

sciencehabit writes "Computer simulations of tiny robots with rudimentary nervous systems show that, over hundreds of generations, these virtual machines evolve altruistic behaviors. They begin to share small disks — a stand-in for food — with each other so that their comrades' traits are passed on to the next generation. Experts say the study sheds light on why various animals — from bees to humans — help each other out, even when it hurts their own chances to reproduce."

      You quite possibly provided the answer without realizing it--I suspect the advantage comes from the increase in genetic diversity, at least as far as species that utilize genetics are concerned. Family has nothing to do with it--species often mate outside the core familial structure. We humans are a good example. We have developed an actual taboo or disdain for mating within the family.

      The really interesting aspect of this, to me at least, is how something like this can develop without a conscious effort--it's not like every species out there even knows about genetics, so what pressures are driving such "altruism"?

      And there is the confounding variable that because society rewards altriusm (for obvious reasons), individuals will invest in appearing to be altruistic, especially if they actually are not altruistic.

    Altruism (noun): The principle or practice of unselfish concern for or devotion to the welfare of others - dictionary.reference.com

    According to the strict definition, I don't think any theory of evolution could ever explain true altruism, because for altruism in it's pure definition, there simply is no reason. If it has a personal reason, then it is, by definition, not altruism.

    Now that's out of the way, there are a number of ways that the less-strict form of altruism (let's call it 'altruistic behavior' rather) would be able to evolve. Firstly, as mentioned in TFA (yes, I skimmed it.. there were only 2 comments at the time) - it makes sense to exhibit altruistic behavior if it improves the odds of your immediate relatives to survive, thereby carrying on part your genes. The more genes your share, the closer the relative, and the more likely you are to care 'selflessly' for them.

    But in humans, carrying over genes is not the only reason. There is also the matter of respect, and trustworthiness. In order to convince your allies that you are trustworthy and 'good', you would exhibit selfless acts, with no expectation of return from the person concerned, but definite returns from those you know. By always tipping waiters more than required (selfless by any means), your partner sees your selflessness and gains trust in you. Business partners sees this and are more likely to trust you in business ventures. This all improves your chances of reproduction and survival.

    all this is made possible by our fantastic ability to remember and build mental models of specific individuals and relationships, keep tabs on how others acted in the past, and spread the word of any 'egotistic' act to other members of society by means of language. Anyone who is /not/ altruistic (at least as far as others perceives it), is therefore placing himself in distrust, and a disadvantage for carrying over his genes.

    So no, it's not much of a surprise that altruistic behavior evolves in robots with a built-in desire to spread their own genes. But it still is pretty damn cool.

    If you program a device to seek out the possibilities that garner the greatest success, regardless of how that success is defined, won't the device act based on it's programming? Now, if somehow these virtual machine robots are changing their programming as they go, that would be impressive. Of course, being computer simulations, even that feat would be based on the biases imposed in their original programming.

    Altruism has a functional definition when referring to evolution, since it's more philosophy if you want to think about animals or bacteria acting morally. I can't recall the precise definition off the top of my head, but it's something along the lines of helping another at personal cost. As I recall, there are three major theories as to why organisms do this.

    First is Kin Selection, which is what the article seems fixated upon. Bees and naked mole rats are the classic example. Essentially, it means you'd take a 10% risk of removing yourself from the gene pool to save an individual who shares 15% of your genetic material.

    The second is reciprocity. Vampire bats may give a starving individual a blood meal to save their life, and it's a lot more likely if the starving individual offered a blood meal in the past.

    The third, and most difficult for people who don't understand math to wrap their head around, is trait group selection. Natural selection has a mathematical model. This is a corollary of that model. In nature, animals form large numbers of groups, either transiently or permanently. Within a group, a non-altruist will always out-compete the altruists and reproduce at a higher relative rate. However, groups with more altruists will reproduce at a greater rate relative to groups with more non-altruists. Overall, you often can have altruists increasing in absolute number despite falling in relative concentration within each group. This process is iterated over generations or within multiple (perhaps infinitesimal) groups that the individual forms within it's life. Being a purely mathematical phenomenal, I would suspect this would emerge within any appropriately complex computer model (it did for the one I wrote for my final project in my Evolution elective back in college).

    OTOH, the entire concept of altruism seems offensive to some people. I'm not trying to say any of these are "true altruism", since they happen all the way down to bacteria secreting proteins that deactivate antibiotics, subsequently protecting nearby unrelated bacteria. It's an explanation for observable animal behavior that humans also demonstrate.

The parts were something like a computer, a welder, a gripper, a battery, a radar, and another rock-like item. The first robot was programmed to collect parts to attach to itself to duplicate itself as two similar halves as a sort of repair process back towards and ideal, and then cut itself in two, and then each separate piece was supposed to go off and do the same. But I did not think it through all the way, and the first thing the original robot did as the copy started up was to start to cut the copy in two to reuse the parts because they were the closest available that were not in itself. So, the robot was both cannibalistic and killing its own offspring.

    It goes to show how easy it is to make a mistake designing artificial life. I had to add a sense of "smell" to prevent that from happening, where the robots would set a smell on each item they used and would leave similar smelling items (in offspring) alone.
