 | | Human Dolphin | | by Jo Oliver, Oct 4, 2008 | | How is it possible for a blind person to know where objects are at in the world, if they can not see? Echolocation is a unique ability where surrounding objects are sensed by hearing echoes from those objects. This is how dolphins and blind animals, like bats, see. It works on the same general principle as sonar. Sound hard? It is, but there are a few unique blind humans that have this ability. | | Comments(13) Liked It: 14 |
