    Human brain developed 80,000 years ago. 200000 years ago, small groups of people wandered across Africa, looking like us anatomically but not thinking the way we do today. Studies of fossils and the  rate of mutations in DNA show that the human species to which we all  belong- Homo sapiens has existed for 200,000 years. But the archaeological research of recent years has shown that, even though the most ancient traces of modern humans are 200000 years old, the development of modern cognitive behavior is probably much younger. In the next issue of the well renowned journal of Human Evolution. They present their new findings on the early modern humans that existed in what is now south Africa approximately 80000 years ago.
   The findings show that people at that time used advanced technology for the production of spearheads and that the complicated crafting process developed the working memory and social life of humans.
  The technology led to increased social interaction within and across the generations. This happened because the crafting of stone spearheads took a long time to learn and required a lot of knowledge,both theoretical and practical. Producing a stone spearhead also required the ability to plan in several stages. This social learning contributed to the subsequent development of early modern humans cognitive ability to express symbolism and abstract thoughts through their material culture, for example in the form of decorated objects. The excavations have been carried out in a small cave, the location we have studied is called Hollow Rock Shelter and lies 250 km north of Cape Town.
