Recently we showed some concern about vampire bats and their marine, echo locating counterparts but soon humans will be able to play your game!
Humans probably used to rely on echolocation far more in the days before artificial lighting, when we had to find our way round in the dark. The readiness with which people learn sonar suggests to me it may be an inbuilt skill.This Daniel Kish guy is blind but he's using a series of clicks to find his way. This is fantastic news!
Kish is the man that is going to lead the revolution against you, you creepy Bats and Dolphins. You guys thought you could enslave humans but you're wrong. Dead wrong.
Kish's tactics and training methods will certainly lead us to victory over all echolocating enemies foreign and domestic!
Daniel Kish is our real-life John Connor.
May your wings and flippers tremble with fear.
Seriously, though, this might have some awesome functions during times of peace between dolphins and bats and humans:
