An analysis published in JNeurosci of brain scans from more than 600 children and adolescents reveals genetically-mediated associations between the size of evolutionarily novel brain regions and intelligence test scores. Genetic influences on the brain follow the patterns of evolutionary expansion of the human brain relative to nonhuman primates.

Cerebral surface area has expanded dramatically over the course of human evolution. Brain regions that have undergone evolutionary expansion tend to follow a similar pattern during individual development. Despite these trends, brain structure can vary greatly between similar people. The relative contribution of genetic and environmental factors to individual differences in cerebral surface area in children has been unclear.

    Are you saying vaccination causes insufficient exposure to sunlight?

    No, I'm saying that it has been established that insufficient sunlight during pregnancy can cause autism [spectrumnews.org].
