The mystery of the human chin: a feature found in no other species
Every human who has ever lived shares a unique anatomical trait, yet no other animal on Earth possesses it. This video explores the biological enigma of the chin—a small facial shelf whose evolutionary purpose remains a mystery to scientists.
