How did humans evolve to be predominantly right-handed?

Asked by Brian1946 (32832points) January 4th, 2011

I’ve read and it seems that about 85% of all humans are right-handed, and I wondered how and when this evolved.

I was born a southpaw and was converted to a northpaw by a Catholic school (Torquemada Elementary or so it seems).

Should there be an SLF- a Southpaw Liberation Front? Shall the British Isles and Australia(?) be the new homeland of our people? ;-)
