Modern group selectionists are often explicit that it is cultural traits they are talking about, or even that they are agnostic about whether the traits they are referring to are genetic or cultural.
University of Michigan Press. In a typical experiment with repeated rounds of play, free riding takes over and the public contribution dwindles to zero. If a group is annihilated, all the people in it, together with their genes, are annihilated.
If a group acquires territory or food or mates, the windfall will benefit some or all of its members. Their pitched battles are noisy spectacles with few casualties, while the real combat is done in sneaky raids and ambushes in which the attackers assume the minimum risks to themselves.
In defence of inclusive fitness theory. Knowledge Representation The study of how knowledge about the world can be represented and what kinds of reasoning can be done with that knowledge.
Sure, some things last longer or do better in competition than others because they have traits that help them last longer or compete more effectively. Continuity and change in the evolution of warfare. If it is meant to explain the cultural traits of successful groups, it adds nothing to conventional history and makes no precise use of the actual mechanism of natural selection.
Subsequent experiments have shown that most of the behavior in these and similar games can be explained by an expectation of reciprocity or a concern with reputation.
The social conquest of earth. The surprise is that people will sometimes punish free-riders even if they have to pay for the privilege, and are assured by the experimenters that everyone is anonymous and no one will meet up with their partners again.
Her work involves applications of neural networks taking inspiration from how the brain works. And when the concept is made more precise, it is torn by a dilemma.
But do humans instinctively volunteer to blow themselves up or advance into machine-gun fire, as they would if they had been selected with group-beneficial adaptations? Secondly, making systems that could learn by themselves, for example, the GPSdeveloped by Allen Newell and Herbert Simon, which was capable of solving a greater extent of common-sense problems.
There are constraints that evolution had to meet. If you create an artificial system its not integrated with the environment and actually motivated by itself. The truly Darwinian mechanisms of high-fidelity replication, blind mutation, differential contribution of descendants to a population, and iteration over multiple generations have no convincing analogue.
None of this prevents us from seeking to understand the evolution of social and moral intuitions, nor the dynamics of populations and networks which turn individual psychology into large-scale societal and historical phenomena. That is hardly a gene that could be selected!
In that case, the most parsimonious theory would explain both human altruism and insect eusociality with group selection. Evolutionary Perspectives on War Conference. Individual bodies are simply not passed down through the generations the way that genes are. In tribal warfare among non-state societies, men do not regularly take on high lethal risks for the good of the group.
Sometimes the term is needlessly used to refer to an individual trait that happens to be shared by the members of a group; as the evolutionary biologist George Williams noted,"a fleet herd of deer" is really just a herd of fleet deer.
Compared to the way people treat nonrelatives, they are far more likely to feed their relatives, nurture them, do them favors, live near them, take risks to protect them, avoid hurting them, back away from fights with them, donate organs to them, and leave them inheritances. Altruistic punishment in humans.
Touch-tone phones have prevailed over dial phones because of their competitive advantages in telephone selection. The surprising outcome is a product of the cumulative effects of many generations of replication.
They regularly engaged in slavery, human sacrifice, sadistic punishments for victimless crimes, despotic leadership in which kings and emperors could kill with impunity, and the accumulation of large harems, with the mathematically necessity that large number of men were deprived of wives and families.
So the hard task is to know what the tasks are that you have to replicate on machines, and I think we have a huge way to go. Rather, the "success" consists of monotheistic religions having more people, territory, wealth, might, and influence.
To be sure, some extensions of natural selection to replicators other than genes are rigorous and illuminating, because they preserve the essential features of replicator dynamics. Genesis of suicide terrorism.
And if it took place in a single generation, then natural selection would be banal, since it would add nothing to ordinary physical cause and effect.Daniel C.

We ask whether computers can think in a human fashion. To arrive at the edge of the world's knowledge, seek out the most complex and sophisticated minds, put them in a room together, and have them ask each other the questions they are asking themselves.
αρχη [archê]. Greek term for beginning or ultimate principle. The Milesian philosophers looked for a single material stuff of which the entire universe is composed, while Empedocles identified no fewer than four elements whose mixture makes up ordinary things.
For both Plato and Aristotle, however, the αρχη most worth seeking would be an originating power from which the material. decision procedure.
