Scientists have identified the genes linked to left-handedness

The genes linked with left-handedness result in differences in brain structure, the scientists found.

(CNN)For the first time, scientists have identified the genetic differences associated with left-handedness, a trait found in 10% of the human population.

What's more, those genetic variants result in differences in brain structure, which might mean that left-handed people have better verbal skills than the right-handed majority.
While previous research into twins has indicated that genes are at least partially responsible for controlling handedness, the new study, conducted by scientists from the University of Oxford and published in the journal Brain, is the first to identify which genetic variants separate the lefties from the righties.
The research could suggest a potential correlation between left-handedness and superior verbal skills, said Akira Wiberg, a Medical Research Council fellow at the University of Oxford who worked on the study.
