Certain tools needed a certain type of thought process in order to be made. Therefore, you needed to be more educated to make more useful tools. Being more educated could indicate that communication could've been easier for certain hominids. .
Pogue also brought up the topic of human relation to apes. Apes exhibit a certain kind of behavior that's similar to laughter during their developmental stages, which mirrors the behavior of a human baby. This type of laughter occurs when the apes participate in playful wrestling. Pogue explains that this could indicate a relation between apes and humans. Apes and humans share many similar characteristics, such as laughter and communication. Non-human primates and human bone structure also shows a large resemblance between the two groups. .
This helped me to further understand chapter four of the Haviland text because it showed me how human traits, such as tool making and the development of language, are related. According to the PBS video, tool making was necessary for the development of language. The more advanced the tool making was, the more the brain developed, helping Homo erectus and Neanderthals develop a more advanced vocabulary. In the movie Quest for Fire, the film follows a Cro-Magnon tribe that relies on a guarded flame that they use to ignite larger fires. The small flame was held in a basket made of bone that contained burning coal (the only way to keep the fire alive). Eventually, the fire gets dropped and the fire stops burning. Unfortunately, the tribe doesn't know how to make fire, so the elder of the tribe sends three men on a quest to find fire. On their journey, they find a woman from a Homo erectus tribe who is far more advanced than they are. She introduces laughter, fire, and strangely, the missionary position to them. In the end, one of the men from the tribe impregnates her. .
The movie helped me further understand the development of people today because it taught me that the Neanderthals and other hominids had to interact to further their knowledge, such as acquiring fire and developing emotions/language.
