Language isn't exactly known where it originated from. What we do know is that humans evolved to speak thanks to a mutated gene called FOXP2. The gene is known to have been around us 150,000 years ago. Although a form of the FOXP2 gene is found in chimps, there is a deficit that doesn’t allow them the same lip and tongue movements to have clear speech. Homo sapiens being able to have speech created a window of opportunities. We were now able to create, store, and pass down information. Non-human communication is like call systems and sign language. Only humans can actually speak, but animals use other methods to communicate. Call systems are vocal systems of a limited number of sounds that are produced when something in particular in the environment is encountered. These calls vary in intensity and duration, and also not as flexible as having a set language because they cannot be combined. The other non-human communication method is sign language. Sign language is able to be learned by apes because there is no actual speaking using a voice, but using their hands.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
