Sexual selection and intelligence: Does sexual reproduction drive the evolution of intelligence?
چکیده انگلیسی

The basal hypothesis discussed here is the idea that brain architecture could be plastic on a very basal, genetic level due to sexual recombination and reassortment of alleles of genes related to brain development, e.g., neuronal cell adhesion molecules (NCAMs) and others.The role of sexual reassortment leads the study of brain development, species behavior and intelligence to a new version of the so-called “Red Queen Hypothesis”: using the mechanism described here, a kind of runaway selection mechanism seems to arise. Even if NCAMs are almost constant within an individual, they seem to act very differently at the population level and so the role of reassorting polymorphic NCAM- (and other) genes gets particularly clear. If several NCAM–NCAM combinations cause extreme behavior and intelligence variability in a population, these combinations also represent a use of sexual selection. This mechanism of NCAM allele assortment seems to be important for the process of speciation by mutual selection of individuals. Therefore NCAM variants and their associated behaviors are thought to be important for the development of intelligence, in that they promote the attraction of individuals with already high intelligence, leading to the speciation of super-intelligent groups.
