Did Cammie Validate Hamilton's Rule by Sharing Her Chip?
May 4 2011, 4:26 AM EDT
In 1964, biologist W.D. Hamilton proposed a precise set of conditions under which altruistic behavior may evolve, now known as Hamilton's rule of kin selection. Here's the gist: If an individual family member shares food with the rest of the family, it reduces his or her personal likelihood of survival but increases the chances of family members passing on their genes, many of which are common to the entire family. Hamilton's rule simply states that whether or not an organism shares its food with another depends on its genetic closeness (how many genes it shares) with the other organism...Previous experiments by Floreano and Keller showed that foraging robots doing simple tasks, such as pushing seed-like objects across the floor to a destination, evolve over multiple generations. Those robots not able to push the seeds to the correct location are selected out and cannot pass on their code, while robots that perform comparatively better see their code reproduced, mutated, and recombined with that of other robots into the next generation - a minimal model of natural selection. The new study by EPFL and UNIL researchers adds a novel dimension: once a foraging robot pushes a seed to the proper destination, it can decide whether it wants to share it or not. Evolutionary experiments lasting 500 generations were repeated for several scenarios of altruistic interaction - how much is shared and to what cost for the individual - and of genetic relatedness in the population. The researchers created groups of relatedness that, in the robot world, would be the equivalent of complete clones, siblings, cousins and non-relatives. The groups that shared along the lines of Hamilton's rule foraged better and passed their code onto the next generation... http://www.physorg.com/news/2011-05-robots-validating-hamilton-video.html Was JF that far ahead of his time through Cammie's selfless sharing? Do you find this valuable?

Cameron's ultimate goal was to win the war against Skynet.This meant protecting John Connor because he is key to leading the Resistance to victory. This also meant trying to destroy Skynet precursors in the present day, like getting Sarah to burn the Turk. Finally, this obviously also meant saving and allying with John Henry, who would be essential in helping the Resistance beat Skynet in the war in the future. So she protected John Connor from getting killed by Cromartie, who was the last terminator sent with the express mission of killing John Connor. She got Sarah to destroy the Turk, which was the basis for Skynet in her own future.And she realized John Henry was not going to become Skynet. Sharing her chip both saves John Henry and takes a major step in cementing his alliance against Skynet. Do you find this valuable? |

"So, she DID validate Hamilton's Rule by sharing her chip."No, not really. To quote you in the OP -- "Hamilton's rule simply states that whether or not an organism shares its food with another depends on its genetic closeness (how many genes it shares) with the other organism..." Neither Cameron nor John Henry have genes, so she can't be following this rule. Also, the rule says the basis for a decision to share depends on the (genetic) closeness of the two creatures. But the basis for Cameron deciding to share with John Henry is her goal of wanting to beat Skynet, not closeness. I would assume she would have shared resources with a creature from another galaxy if it meant Skynet would be defeated. Do you find this valuable? |

But she shared her coding, as demonstrated by Floreano and Keller in their representation of genetic coding - in it's simplest form is a binary coding.

"But she shared her coding, as demonstrated by Floreano and Keller in their representation of genetic coding - in it's simplest form is a binary coding."Even if we make the assumption that they have some similar coding, such similarity is still not the reason for her sharing resources with him. The reason remains her goal of beating Skynet. Yes, in this case, I would be willing to say that their having similar code is a coincidence. Do you find this valuable? |
