pubmed-article:1292954 | pubmed:abstractText | A pleiotropic relationship between intelligence and myopia has been shown to exist. Large eyes (as measured by axial length) have been shown to lead to myopia, and large brains have been shown to be more intelligent. I hypothesized that the myopia/intelligence relationship could arise because a single genetically controlled mechanism affects both brain size and eye size. This hypothesis has testable implications. | lld:pubmed |
