They believed handedness might be tied to how social people have turn out to be over time. It’s not simply biology—it’s conduct, too.
“The extra social the animal — the place cooperation is very valued — the extra the final inhabitants will pattern towards one aspect,” Daniel Abrams, an assistant professor at Northwestern’s McCormick College of Engineering and Utilized Science, advised LiveScience
He added that for any society to perform properly, individuals should work collectively, explaining that this robust want for cooperation doubtless formed human conduct over time, making it extra frequent for individuals to make use of the identical dominant hand.
In consequence, most individuals at this time are right-handed.

Dwelling proudly as a left-handed individual
Regardless of being within the minority, left-handed individuals proceed to indicate resilience and brilliance.
They’ve needed to study to adapt, usually discovering inventive options to on a regular basis issues.
