Why aren't all human beings ambidextrous? Is there an evolutionary advantage to handedness?

I was told by a Neurologist that one side of the brain is usually a bit larger the  other side. When he tested my 9 month old child's brain he stated the only thing he found was her right side brain was a tad larger than the left. He told she would definitely be left handed and she is.
