The vocal apparatus is located near the base of the skull and is made up of soft tissue which is connected to bones. The shape of those bones and their position in the throat determine the sounds which are able to be produced. (Park, 2011) Even the earliest humans were able to make sounds, but was positioned in a way that would resemble that of chimpanzees, however around the time of Homo erectus, the vocal apparatus would be positioned lower in the throat comparable to modern humans, and would allow for similar vocal communication. (Park, 2011) Nevertheless, the ability was there, but knowing if language was used, is still a …show more content…
5th Edition McGraw-Hill/Irwin 5) What is the general focus of sociobiology (also known as evolutionary psychology and behavioral ecology)? How is this applied to human behaviors? Sociobiology is, defined by Park as, the scientific study that examines evolutionary explanations for social behaviors within species.

Park goes on to describe a scenario using sociobiology to try to explain why people would kill their offspring. The behavior can be seen in other animals, as well. Male lions kill the offspring of other males to guarantee genetic success within the pride. In some cultures, people have been known to kill their female infants, due to the need of male warriors. (Park, 2011) Another example would be in the reasons why there is attractions between the opposite sex yet inbreeding is often avoided and considered taboo. Through these examples, culture and biology are entwined.
