Matthews found a German study which looked at what he called 'mixed-handedness',that is,the capacity to use both left and right hands equally.It looked at mised-handedness in 40 musicians on a variety of instruments.Researchers examined a number of variables,e.g. type of instrument played,regularity of practice undertaken and length of time playing instrument...and found the following:keyboard players had high levels of mixed-handedness,whereas string players like cellists and violinists strongly favoured one hand.Also those who started younger were more mixed-handed.

Matthews also reports studies of handedness in apes.Apes get a large proportion of their food by 'fishing' ants from ant hills.The studies show that apes,like humans,show handedness-though for them right-and left-handedness is about equal,whereas about 85% of humans are right-handed.Studies showed that apes consistently using the same hand fished out 30% more ants than those varying between the two.
