Oxford academics assess why we are left or right-handed

Researchers at Oxford University believe they are a step closer to understanding why people are either left or right-handed.

They have discovered a biological process that happens when an embryo is developing, could determine which hand you will use to write or play sport with.

William Brandler, a PhD student at Oxford University, said genes involved in determining which hand people will prefer influence the brain.

Famous "lefties" include Prime Minister David Cameron, President Barack Obama and tennis star Rafael Nadal.
