Sorry, but Humans can echolocate, just not very well. Have you ever heard a sound and turned your head to locate the direction that the sound was comeing from, That is echolocation. There was an episode of 'Truth or Consenquences' where a contestant was seated and blindfolded and asked to determine the direction of a small bell without turning her head. She had great dificulty till she was able to turn her head to track the sound, and then it was quite easy. Humans do Echolocate both in direction and distance, but not as accurately as some other animals.
