Great Minds Think Alike: Bats & Dolphins Evolved Same Gene For Echolocation

Bats and dolphins are two of the most celebrated users of echolocation, employing high-frequency sounds to locate prey, find their way, or to communicate. Now a new set of findings in Current Biology show that not only do the two different kinds of mammals use the same method, they also evolved nearly the exact same molecular means for hearing at high frequencies. That second part was a surprise, study author Stephen Rossiter says:
