  Karl Sims: Artifical Evolution for Computer Graphics
Evolution is now considered not only powerful enough to bring about biological entities as complex as humans and consciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design.
Artificial evolution of these expressions is performed by first generating and displaying a population of simple random expressions in a grid for interactive selection.
Artificial evolution has been demonstrated to be a potentially powerful tool for the creation of procedurally generated structures, textures, and motions.

Artificial intelligence theory also draws from animal studies, in particular with insects, which are easier to emulate as robots (see artificial life), as well as animals with more complex cognition, including apes, who resemble humans in many ways but have less developed capacities for planning and cognition.
Artificial intelligence began as an experimental field in the 1950s with such pioneers as Allen Newell and Herbert Simon, who founded the first artificial intelligence laboratory at Carnegie-Mellon University, and McCarthy and Marvin Minsky, who founded the MIT AI Lab in 1959.
The vision of artificial intelligence replacing human professional judgment has arisen many times in the history of the field, in science fiction and today in some specialized areas where "expert systems" are used to augment or to replace professional judgment in some areas of engineering and of medicine.

 Artificial Life   (Site not responding. Last check: 2007-10-26)
The purpose of this conference is to bring together researchers in neurosciences, ethology, cybernetics, artificial intelligence, robotics, and related fields to improve our understanding of the behaviors and underlying mechanisms that allow animals and, potentially, robots to adapt and survive in uncertain environments, and to simulate those mechanisms in robots and autonomous synthetic systems.
The idea is based on ecology-inspired artificial life models in which a distributed population of intelligent information agents (infospiders) survives by searching and retrieving documents online, on behalf of the user, in networked information environments such as the Web.
The main aim of the CAM-Brain Project is to build/grow/evolve an artificial brain by 2003 with a billion artificial neurons.

 Artificial Evolution
Evolution may have been triggered by new viruses arriving on earth from space and some think that these mechanisms may have been used by advanced alien geneticists to produce modifications to existing forms of life or producing new forms of life.
In light of my previous article on “Life Begins in Space” which refers to Fred Hoyle’s hypothesis on space bacteria incorporated into protoplanetary dust, the further potential for seeded life to evolve into the diverse forms of multicellular organisms through such mechanisms as recombination and gene transfer becomes an item of interest.
The SET states that the evolution of eukaryotes from prokaryotes involved the symbiotic union of several previously independent ancestors.

 From Artificial Evolution to Artificial Life
An artificial evolutionary system called Cosmos, which provides a virtual operating system capable of simulating the parallel processing and evolution of a population of several thousand self-reproducing computer programs, is introduced.
The results of this work, and consideration of the existing literature on artificial evolutionary systems, leads to the conclusion that artificial life models such as this are lacking on a number of theoretical and methodological grounds.
It is suggested that the study of open-ended evolution can lead us to a better understanding of the essential properties of life, but only if the questions being asked in these studies are phrased appropriately.

 Evolution - A-Z - Artificial selection   (Site not responding. Last check: 2007-10-26)
Artificial selection is the selective breeding carried out by humans to alter a population.
It is a procedure often used in agriculture: artificial selection has been used to alter the number of eggs laid by hens, the meat properties of bullocks, and the milk yield of cows.
A kind of artificial selection has generated almost all our agricultural crops and domestic pets, such as this labrador pictured opposite.

 Evolving AI-Life by Natural Selection (Alastair Channon's Artificial Life)
An (artificial) environment containing simple virtual autonomous organisms with neural controllers has been created to satisfy these requirements and to aid in the development of an accompanying theory of evolutionary emergence.
Purely artificial selection models, such as traditional genetic algorithms, are argued to be fundamentally inadequate for this calling and existing natural selection systems are evaluated.
Abstract: The traditional fitness function based methodology of artificial evolution is argued to be inadequate for the construction of entities with behaviors novel to their designers.

 Moshe Sipper, The Artificial Self-Replication Page
Description: Langton observed that although the capacity for universal construction, as studied by von Neumann and Codd, is a sufficient condition for self-replication, it is not a necessary one.
The embryonics team developed an artificial cell, dubbed biodule (biological module), that is used as an elementary unit from which multicellular organisms can ontogenetically develop to perform useful tasks.
A major contribution of the thesis was to analyse the reasons for failure, to identify weaknesses (both methodological and theoretical) of this kind of study of self-replicating programs in general, and to suggest ways for improving evolvability in future systems (see refs 1 and 2).

 Kevin Kelly -- Chapter 15: Artificial Evolution
After a few hours of operation, Tom Ray's electric-powered evolution machine had evolved a soup of nearly a hundred types of computer viruses, all battling it out for survival in his isolated world.
With a fl box that contained evolution he could demonstrate the historical principles of ecology, how a rain forest descends from earlier woods, and how in fact ecologies emerge from the same primordial forces that spawn species.
Ray's solution to the problem of making an electronic evolution machine was to start with simple replicators and give them a cozy habitat and plenty of energy and places to fill.

 Measuring the Dynamics of Artificial Evolution
At present, measuring adaptation and fitness is one of the main issues in evolutionary theory and artificial life.
The notion of splitting the evolution of the system into epochs presented here is consistent with the notion of "epochal evolution" proposed in [20].
Epochal evolution assumes existence of subbasins of attraction in the genome phase space; these are connected by portals.

 Feature Article - The Evolution of Artificial Intelligence
Artificial intelligence has long been considered an interesting plot device for science fiction stories—but not much more.
The origins of the concept of artificial intelligence can be traced back decades in popular science fiction, but as a true scientific pursuit it is a very young area of study.
If the human could not determine which of its conversations were with a person and which were with the machine, the test had been passed and the machine would be considered intelligent-now known as "artificial intelligence," a phrase later coined by John McCarthy, co-founder of the MIT AI lab in 1956.

 Adaptive Dynamics Network - Evolutionary Algorithms and Artificial Evolution
As a case study in evolutionary computation, the ADN program is exploring evolutionary algorithms for the artificial synthesis of controllers that are represented by neural networks.
A major feature of such a scheme is that the evolutionary 'learning' in populations of these networks does not only modify weights and thresholds within a given network architecture, but at the same time alters and improves architectures themselves.
In view of the intricate relation between the structure of a neural network and its function, the evolution of neural controllers also serves as an interesting example of complex genotype-phenotype mappings.
