Scientists have identified a series of genes that may influence whether you are right handed or left handed. Oxford University researchers have found the genes involved in the early development of an embryo, may help establish left-right differences in the brain, which in turn influence whether a person is left or right handed.

And while these findings don’t completely explain right and left handed differences in people, the team believes it contributes toward which hand we will favor.

About 90% of people are right handed and humans are the only species with such a strong bias in handedness.
