Is there something hardwired in us that results in a more significant portion of people being right-handed?

Maybe this is a common misconception but as a leftie I've noticed I'm one of the few in my classes who suffers from smudged writing and bumping elbows with people at the table. Is there a reason behind right handedness being the default?

We don't really know *why* this is the case yet, but we do know the shift did occur in early humans 

Some have argued that it all comes down to language. Just as most people are right-handed – a trait, remember, controlled by the left side of the brain – so do most people do the bulk of their linguistic processing in their brain’s left hemisphere. Indeed, this left-brained specialization for language is even more common than right-handedness – which might suggest that as the left hemisphere evolved for language, the preference for the right hand may have intensified simply as a side effect. This is called the Homo loquens hypothesis: lateralization in general was driven by the evolution of an upright, bipedal stance, while the rightward preference was driven, some time later, by the evolution of language.
