Right-handed bias not left of field

PEOPLE who are right-handed outnumber those who are left-handed nine to one, and a recent study of fossilised teeth has shown this phenomenon goes back at least 500,000 years.

Scientists studied the scratch patterns on fossilised front teeth that had been accumulated over the individuals’ lifetimes. 

The oldest were from Neanderthal remains found near Burgos, Spain.

The researchers found right-handedness in 93% of individuals.
