The Brain & Being Left-Handed
No-one has come up with a definitive reason for WHY some people are left-handed, but about 13% of the population around the world are, and it is thought to be genetic - it definitely runs in families. If you are left-handed, you have that gene and will pass it on through the generations.
The way the brain works is incredibly complex, but this simplified explanation will give you some understanding of where our left-hand dominance comes from. The brain is "cross-wired" so that the right hemisphere controls the left side of the body and vice-versa. If you are right-handed, your dominance comes from your brain’s left hemisphere.
It’s not strange to find people who favor the opposite hand and foot (e.g. left hand and right foot), and some people are lucky enough to be ambidextrous, meaning they can use their left and right sides with equal skill.
