Rather, it is more likely other copy an orangutan innovative sound because the sound serves a function. – This is a very strong indication that different sounds are learned among wild populations and not purely genetically or ecologically based, Wich said. This is a great indication that orangutans can learn sounds not in their repertoire from a different species, and they are flexible in dealing with them. .. That compares with what scientists believe Rather social learning in wild orangutan populations. For example, previous work by Dr. Van Schaik and colleagues showed that wild orangutans in one population raspberry sound when giving nest, and orangutans in another population make nest smack engage engage in the same activity.

Scientists have long known that orangutans copy physical movements of people, but shows Bonnie pipes scientists believe ability to learn from orangutans and other great apes in the auditory domain to be more flexible than previously believed, said Wich. The behavior goes against the argument that orangutans have no control over their vocalizations and the sounds are purely emotional – that is, an involuntary response to stimuli such as predators.The method reported was synchronous populations of hepatocytes, which were generated in clinically preferred conditions of with minimal use of serum and cells shuttle highly enriched populations of definitive the endoderm it HES and then.
