DFrom pointing to nodding,humans use signs to help communicate when talking to each other.Apes()
also have their own special signs to show what they mean.According to a new study,humans can understand the
signs of apes
②Chimpanzees(黑猩猩)and bonobos(小黑猩猩)are two kinds of apes that are closest to humans.They
use about 80 different signs to show what they mean.For example a sign the scientists call"big loud scratch(
)"means "help pick insects off me".Scientists have learned the meanings of these signs by studying them for
years.Though the two groups of apes use different signs in a few cases,they share 90%of the same signs.
3Kirsty Graham and Catherine Hobaiter at the University of St Andrews wanted to see if humans with no
training or experience could understand the signs of chimpanzees and bonobos.They created a game for people to
play online.The game was simple.People watched short videos of apes making a sign.Then they had to choose
the correct meaning of the sign out of four possible answers.For the videos,the scientists chose 10 of the most
common signs used by chimpanzees and bonobos.5,656 people played the game.
4The scientists were surprised to find that people were able to choose the correct meaning of the signs over
50%of the time.That's twice as good as people would be expected to do by chance.For some of the signs,people
were able to choose the correct meaning about 80%of the time.One example of this was the sign of"wiping the
mouth”meaning“give me that food”.
5The scientists believe that humans may have a natural ability to understand the signs of apes.But it's not
clear why.They need to study how humans are able to understand the signs of apes They're also curious about
how humans understand other animals,like dogs.
