is a large focus of studies from years past until current day in order to discover more about the evolution of language, especially human language. Knowing that humans evolved from primate lines, people seem to focus a lot of research efforts towards these animals. Humans know that people are extremely social animals, but the non-human primates can be quite social themselves; these social needs encourage development and evolution of communication and language to help with survival needs. If social interaction is essential to better survival of an animal, then the need for social communication is at a high priority evolutionarily speaking.
So an important thing to distinguish when examining ability of non-human primates with communication or language is the actual defined difference between language and communication, and exactly where the definite line of distinction might be separating the two, if there even is a line to be considered when looking at so many different animals. Non-human primates have been studied and observed for both communication and language capabilities and distinction is often necessary to understand what has been discovered and what can be discovered. Many researchers of non-human primates argue that they cannot and do not have the capability of language, while others believe that non-human primates do have language, or can be taught forms of language by humans. Some researchers, that believe that non-human primates do have language or can be taught language, realize that it may not be the same level of complexity as that of human language as a whole but that it is a simple but true language form nonetheless. The reality is the definition of language and communication are what truly can determine if research can show non-human primates having language and or the ability of learning human language when trained, so each research can have potentially a different
definition.
