Temperature and evolutionary novelty as forces behind the evolution of general intelligence ¬リニ

چکیده
How did human intelligence evolve to be so high? Lynn [Lynn, R. (1991). The evolution of race differences in intelligence. Mankind Quarterly, 32, 99–173] and Rushton [Rushton, J.P. (1995). Race, evolution, and behavior: A life history perspective. New Brunswick: Transaction] suggest that the main forces behind the evolution of human intelligence were the cold climate and harsh winters, which selected out individuals of lower intelligence. In contrast, Kanazawa [Kanazawa, S. (2004). General intelligence as a domain-specific adaptation. Psychological Review, 111, 512–523] contends that it is the evolutionary novelty of the environment which increased general intelligence. Multiple regression analyses support both theories. Annual mean temperature and evolutionary novelty (measured by latitude, longitude, and distance from the ancestral environment) simultaneously have independent effects on average intelligence of populations. Temperature and evolutionary novelty together explain half to twothirds of variance in national IQ. © 2007 Elsevier Inc. All rights reserved.

متن کاملGeneral intelligence as a domain-specific adaptation.
General intelligence (g) poses a problem for evolutionary psychology's modular view of the human brain. The author advances a new evolutionary psychological theory of the evolution of general intelligence and argues that general intelligence evolved as a domain-specific adaptation for the originally limited sphere of evolutionary novelty in the ancestral environment. It has accidentally become ...

| This paper is indulged in exploring the general concepts among the paradigms of Computational Intelligence , especially in Evolutionary Computation. From the viewpoint of adaptive complex systems, we generalize the characteristics of Intelligence as Complexity, Evolution, Sympathy, and Adaptation, as well as elaborate their corresponding meanings and approaches in Artiicial Intelligence. Furt...
متن کاملGene Family: Structure, Organization and Evolution
Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...
متن کاملIntroducing Novelty Search in Evolutionary Swarm Robotics
Novelty search is a recent and promising evolutionary technique. The main idea behind it is to reward novel solutions instead of progress towards a fixed goal, in order to avoid premature convergence and deception. In this paper, we use novelty search together with NEAT, to evolve neuro-controllers for a swarm of simulated robots that should perform an aggregation task. In the past, novelty sea...
