Human Echolocation

An article in September’s Reader’s Digest had an article about Human Echolocation which was amazing! It seems Brian Borowski who was born blind, has developed his senses to navigate the world through echolocation. Bats use echolocation by emitting a sound and waiting for the sound waves to bounce back in order to give the bat an ‘image’ of their environment. He emits clicking sounds with his tongue or jingles coins in his pockets to produce the sound he needs to create an echo.

According to scientists, everyday folks are able to utilize human echolocation but the only reason we are unable to is because we never developed our sense of hearing for that purpose. Practice makes perfect and someday we might evolve enough to be able to move about in the dark.

The person in the article was born blind therefore he didn’t really have an option but most probably for something to evolve with this ability, it would probably have to have a heavy dependency on it. Bats are apparently quite blind so sound helps them ‘see’ in a sense. There was also a documentary once about someone being able to ‘see’ through their skin. I’m guessing his sense of touch and feel is behaving like his eyes by feeling changes in the air currents and temperature around him to create an image in his brain.
