How Much Hard Evidence Do You Need?“[T]hree dopamine genes … examined, the dopamine transporter gene (DAT1), the dopamine D2 receptor gene (DRD2), and the dopamine D4 receptor gene (DRD4), had small but reliable effects on educational attainment, such that those with a higher ‘dopamine index’ tended to attain less education…. But what’s much more interesting is that they found significant differences in the prevalence of the alleles of theses genes between the White and the Black subjects, with Blacks having tending to have higher dopamine indices.” – from jayman (at his new location!).

“Gene Activity in the Brain Depends on Genetic Background”“Taken all together, the data from the study demonstrate that closer genetic relatives exhibit fewer differences in gene expression patterns, whereas more distant relatives show greater variation. Interestingly, the researchers found that the expression variations between genetic strains were more likely to be found in areas of the brain that evolved more recently. These regions are most commonly linked to higher order functions such as cognition, social behavior, learning and memory.”

“A thirst for excitement is hidden in your genes”

“Sensation seeking—the urge to do exciting things—has been linked to dopamine, a chemical that carries messages in your brain. For a new study published in Psychological Science, a journal of the Association for Psychological Science, scientists analyzed genes in the dopamine system and found a group of mutations that help predict whether someone is inclined toward sensation seeking….”
