Why are some people ambidextrous?

Ambi-what?! An ambidextrous person is able to use both hands effectively, rather than being left- or right-handed. But how come?

According to certain studies, people who write with their right hands tend to have brains in which the left-hemisphere is dominant, or stronger … but scientists have yet to prove this. But what about someone ambidextrous? In an article on www.lifeslittlemysteries.com, scientists suggest that neither hemisphere is dominant in an both-handed person’s brain. According to the article, there are generally four variations of handedness: right-handed, left-handed, mixed-handed (when people prefer using their left hand for some tasks and their right for others) and people who are truly ambidextrous.

While numerous studies have been done to find out what exactly causes hand-dominance, no firm conclusions have been made. A very popular theory is that the left side of the brain controls most of the communications functions and therefore would naturally control the hand a person uses to write.

Interestingly, one in every hundred people is born ambidextrous, but don’t cry if you’re not one of them. It’s possible to develop this impressive skill just by practising your fine motor skills – like writing – with the hand you don’t normally use. Just don’t try it out in your exams until your weaker hand catches up …
