Sapiens 9.0分
读书笔记 The Great Leap Forward
Awkward Being

Green monkeys use calls of various kinds to communicate. Zoologists have identified one call that means ‘Careful! An eagle!’ A slightly different call warns ‘Careful! A lion!’ When researchers played a recording of the first call to a group of monkeys, the monkeys stopped what they were doing and looked upwards in fear. When the same group heard a recording of the second call, the lion warning, they quickly scrambled up a tree. Sapiens can produce many more distinct sounds than green monkeys, but whales and elephants have equally impressive abilities. A parrot can say anything Albert Einstein could say, as well as mimicking the sounds of phones ringing, doors slamming and sirens wailing. Whatever advantage Einstein had over a parrot, it wasn’t vocal.
