A 1.8-million-year-old fossil may belong to the oldest right-handed human

As any lefty knows well, our world is largely built for righties. Basic items from scissors and knives to cameras and computer mice are all designed to suit the roughly nine in 10 people who are right-handed.

New evidence suggests this lopsided split may date back more than a millennia, according to an international team of anthropologists.

Researchers said a 1.8-million-year-old fossilized jaw bears the scratches of a person who was right-handed. This finding could help scientists better understand how the human brain developed and when we first developed language.
