For as long as humans have reflected on their own nature, the near-universal preference for the right hand has stood as a quiet enigma — too consistent to be coincidence, too complex to yield easily to explanation. A new study now traces this tendency to its deepest roots: the asymmetrical architecture of the human brain, shaped by millions of years of evolutionary pressure favoring precision, tool use, and survival. What once seemed a cultural quirk reveals itself as a biological inheritance, written into the very structure of how human minds are built. The discovery opens a wider door into u
