• Resumen

  • This article examines the loss of smelling acuity in the human nose during evolution and efforts to find out why this is happening. Scientist have long suspected that the ability to smell different scents is partially hereditary and research backs up that belief. Theories as to why humans have lost some of their sense of smell are discussed from not needing it for survival, to better eyesight to better verbal communication.
