chimps have good manners

Did you know bonobos  are found in the wild  only in the democratic republic  of Congo. A brilliant bonobo A 40 year  old male bonobo named Kaniz communicate  with  humans using  book of lexigrams (symbols  that correspond to words) On an outing to a forest touched the symbols fro marshmallow and fire  when given marshmallow and matches Kaniz make a fire and toasted the  marshmallow. Kinzi  just as humans  say hello and goodbye  to one another before and after year get together researchers have found that some apes use similar signals to start  and  end their social interactions  An international team led by Dr  Raphael  Hessen  of the University of Neufchâtel  in Switzerland studied more than 1,200 interaction involving chimpanzees  and their close relatives bonobos in captivity. Focusing on how the ales began and ended activities like grooming and play the researchers found the apes often exchanged a look or and certain noise just before. sometime they would  butt heads touch each other or hold hands as a way to break the ice. bonobos embrace the researchers say these signal are the star of a joint commitment an agreement to cooperate toward a common goal of some sort. In humans an exchange  of hellos can signal willingness  to have conversation and something similar seems to happen among apes. It is the first time that sign of this joint commitment have been seen in on humans species. Overall bonobos wren  more  polite than chimps  swapping hello signal  or grooming before play 90% of the time.(chimps said hello in about two third of cases.) both auspices were careful  about the end of interaction thought exchanging goodbye signals about nine times out of 10. chimp usually go through a full greeting  ritual with whomever they are interacting with. Bonobos however are more likely to shorten their greeting  with close pals. Dr Hessen pointed out that this is another similarity with humans. When your'er interacting with good friend you 'er less likely to put a lot of effort into communicating politely she said bonobos have few social ranks than chimps and  this may behave more  casually among friends. from celled book the week junior.
