Right-handedness is most common. Right-handed people are more dexterous with their right hands when performing tasks. A variety of studies suggest that 70-90% of the world population is right-handed, rather than left-handed or any other form of handedness.

Left-handedness is less common than right-handedness. Left-handed people are more dexterous with their left hands when performing tasks. A variety of studies suggest that 10% of the world population is left-handed.

Ambidexterity is exceptionally rare, although it can be learned. A truly ambidextrous person is able to do any task equally well with either hand. Those who learn it still tend to sway towards their originally dominant hand.

So left is for the more accurate things, and the right is more for brute force, in general.

I think lefties have a better connection between brain hemispheres, but that is just a theory.

i searched all over but couldnt find why in the human population, is right-handedness so dominant, up to 90% of the world population. in other species, sometimes it is almost always left-handed or (left-clawedness) that is the norm.

what is your theory?

Historically, the left side, and subsequently left-handedness, was considered negative in many cultures. The Latin word sinistra originally meant "left" but took on meanings of "evil" or "unlucky" by the Classical Latin era, and this double meaning survives in European derivatives of Latin, and in the English word "sinister". Alternatively, sinister comes from the Latin word sinus meaning "pocket": a traditional Roman toga had only one pocket, located on the left side. The right hand has historically been associated with skill: the Latin word for right-handed is dexter, as in "dexterity", meaning manual skill. Even the word "ambidexterity" reflects the bias. Its intended meaning is "skillful on both sides". However, since it keeps the Latin root dexter, which means "right", it ends up conveying the idea of being "right-handed at both sides". This bias is also apparent in the lesser-known antonym "ambisinistrous", which means "clumsy on both sides".[8] In more technical contexts, "sinistral" may be used in place of "left-handed" and "sinistrality" in place of "left-handedness".[9]
