Genetic variation, brain, and intelligence differences

Causal Genetic Variation Underlying Metabolome Differences.

An ongoing challenge in biology is to predict the phenotypes of individuals from their genotypes. Genetic variants that cause disease often change an individual's total metabolite profile, or metabolome. In light of our extensive knowledge of metabolic pathways, genetic variants that alter the metabolome may help predict novel phenotypes. To link genetic variants to changes in the metabolome, w...

Genetic contributions to human brain morphology and intelligence.

Variation in gray matter (GM) and white matter (WM) volume of the adult human brain is primarily genetically determined. Moreover, total brain volume is positively correlated with general intelligence, and both share a common genetic origin. However, although genetic effects on morphology of specific GM areas in the brain have been studied, the heritability of focal WM is unknown. Similarly, it...

Social life, evolution of intelligence, behaviour and human brain size

Social life is one of the most critical factors of the evolution of the behavior of non-human primates and humans. Several factors, such as an increase in brain size, adaptive modules, and grooming, are related to the complexities of social groups. Although some scientists have mentioned foraging as a rival hypothesis for the evolution of behavior, in this research, we tried to investigate the ...

Emotional Intelligence and Gender Differences

The present study investigated Emotional Intelligence among male and female. The research sample was comprised of one hundred and sixty subjects (N = 160) who were categorized in two groups.. They were eighty males (n = 80) and eighty females (n = 80) from N.W.F.P. Snowball sampling technique was used to select subjects. Personal information sheet was used to obtain the demographic information....
