What Criteria Would Archeological Information Have To Meet To Be Considered Evidence Of Complex Thought?
One of the most important pieces of evidence in the archeological record that points to complex thought is stone tools. In fact, we even associate the classification of our early ancestors to that of tool making. For example, Homo habilis means “handy man” was chosen. Because this species is thought to is the originator of the many stone tools found at habilis sites. If these stones were indeed created by habilis, then the species had a marked advantage in terms of complex thinking.At about that time, there were at least four hominid species living in East Africa; competition would have certainly been fierce. The ability to make and use tools would have been a significant advantage in competing for food. Hominid skull fossils from this time show a marked encephalization (increase in brain size). Bigger brains require more metabolic energy and using tools to extract more calories from their environment would certainly have helped the first hominid species to discover Stone Age technology.
