bats? how?
Charles Darwin demonstrated human's potential for sonar echo location by successfully navigating Euston Station, London whilst blindfolded in May, 1814.
Darwin, emitting a series of sharp yelps and using a paper cone to listen for resulting echoes, correctly located and boarded the 2.47pm Express to Milton Keynes, thus winning a wager with George Bernard Shaw for 10,000 shares in the Dutch East India Company
Yep the info checks out! How do you think Batman can see in the dark!!!
haha yes he can
Darwin's bet was with Keynes to Shaw station, Bob. Keynes did all the yelping, Darwin simply listened for the echo. The term "keen hearing" originated from this famous demonstration.
