One can understand from the passage that unlike what is commonly accepted, ----.

An application to translate chimp language may be
available in the near future! Chimpanzees can learn
to pronounce 'apple' in two chimp languages – a finding
that calls into question how unique our own language
ability is. Katie Slocombe of the University of York, UK,
and her team recorded vocalisations by a group of adult
chimps from the Netherlands before and after their
relocation to Edinburgh Zoo. Three years after the
move, the Dutch chimps has picked up the
pronunciation of their Scottish hosts. The peak
frequencies of the Dutch chimps' loud calls fell from 932
to 708 hertz to match closely with the low-toned
pronunciations of the Scottish apes. The change was
gradual and coincided with the growing friendship of the
two groups. This means that, like us, chimps can learn
foreign language to fit in with new neighbours. The
finding also challenges the prevailing theory that chimp
words for objects are fixed because they result from
excited, involuntary outbursts. The general assumption
was that animals do not have control over the sounds
they make, whereas we learn the labels for things
socially, which is what separates us from animals,
states Slocombe. But this may be wrong, it seems. "It is
the first time call structure has been dissociated from
emotional outbursts," she says
