Among the many traits that distinguish humans from their primate relatives, the near-universal preference for the right hand has long stood as an unexplained curiosity. A team at Oxford University, drawing on data from over two thousand primates across forty-one species, now argues that this ancient asymmetry is not accidental but is written into the very architecture of what it means to be human — shaped by the moment our ancestors rose onto two legs and the long expansion of the thinking brain that followed. The finding invites us to see something as ordinary as which hand we reach with as a
