Calling ourselves human is our way of categorizing ourselves as a superior species. Although we are distinctly different, we should accept that we are in the same family as chimpanzees. Acknowledging that fact doesn 't mean you are calling yourself a chimp. For example, a dog isn 't a wolf even though they are from the same family. We are humans. What is it about our physical and behavioral traits that enable us to develop uniquely human capabilities? Traits like language, hunting skills, spiritual and ritual beliefs, bipedalism, and brain capacity
The human language might not be universal among humans, but the physical traits that make language possible are universal. About 300,000 or more years ago, the basicranium started evolving to a more flexed or bent position. The basicranium is the floor of the brain 's case. With the basicranium flexed, the larynx (voice box) is low in the neck so we can produce more speech sounds. The basicranium is an indicator of how well an animal can articulate sounds. Other evolutionary, corporeal indications are the position and shape of the hyoid bone that anchors muscles connected to the jaw, larynx, and tongue. The Broca 's area of the brain controls these muscles as they function to produce speech sounds. These, and other, adaptations like breathing control, vertebral canals larer, tongue innervations and length of the pharynx are all physical characteristics of communication. The evolution of language also enhanced human intelligence. Having the ability to communicate allowed for the uncomplicated transferring of complex ideas and allowed for teaching. Having the intelligence facilitated by language is a main quality that makes us human.
When it comes to language chimpanzees, our closest living relatives communicate verbally using a variety of hoots, grunts, screams, pants, and other vocalizations. But, a majority of their communication is done through gestures and facial expressions. Chimps
