Similar to humans, our closest relative, chimpanzees also work together and share food with their close relatives, reciprocating partners or potential mates (Hogenboom, …show more content…
The anatomical prerequisite for humans to gain the ability to speak such as the absent and present of the air sac in hominids. Morphological changes of the face structures such as the growth of the supralaryngeal vocal tract and the descent of the larynx are the anatomical aspect of the possible contribution to the human speech. Bart de Boer (2012) studied the anatomical structure that involves the loss of air sacs serves as the possible evidence to why modern humans can produce complex language. The air sacs are present in apes and absent in modern humans and Homo neandethalensis is the interesting piece to why we and the Neanderthal are capable of speaking while the others cannot. de Boer (2012) concluded having an air sac sitting in the vocal tract results in a blockage of clear
