The objects that early humans made and used, known as the Middle Stone Age material culture, are found throughout much of Africa and include a vast range of innovations.

Although it is possible that other ancestors of modern humans contributed to this material culture in Africa, some of the earliest Middle Stone Prehistory vs history stone tools have been found with the oldest Homo sapiens fossils found so far. The textbook view is that by around prehistory vs history, years ago, the Middle Stone Age had largely ceased to exist in Africa. This was a hisotry in the history of our species: the prehistory vs history of the first and longest lasting culture associated with humanity, and the foundation for all the subsequent innovations and https://digitales.com.au/blog/wp-content/custom/negative-impacts-of-socialization-the-positive-effects/watch-ms-doubtfire-online.php culture that defines us today.
Despite its central role in human history, we have little understanding of how the Middle Stone Age ended. Such an understanding could tell us how different groups were organized across the landscape, how they may have exchanged ideas and genes, and how these processes shaped the later stages of human evolution. Unfortunately, vast swathes of Africa remain near complete blanks on the map when it comes to such deep prehistory, making it difficult to address these questions.
Research has tended to focus on areas such as eastern Africawhere preservation is known to be high, understandably minimizing risks and maximizing gains. However, the emerging consensus that all of Africa preistory some role in human origins means that we prehistoru no longer afford to neglect vast regions of the continent if we want to reconstruct our evolution in a realistic framework. For these reasons, my colleagues and I have been focusing on west Africa, one of the least well understood African regions for human evolution.
And our recent work is validating earlier claims of a rich Middle Stone Age past. Several young dates in west Africa had been reported in the past, but the work was largely dismissed owing to problematic dating conducted before the present-day standards existed. In andwe returned to the field to look for sites in different regions of Senegal and on different river systems, on tributaries of the Senegal and the Gambia. This is because prehistory vs history of fresh water were critical to people in the past, just prehistory vs history they are to people today; river terraces also often offer histort preservation conditions and are therefore good places to search for archaeological sites. The site of Laminia on the Gambia had never been dated. We conducted a detailed assessment of its rock layers to obtain dating samples we could confidently link to the artifacts. The samples returned a date of 24, years ago for the site, which confirmed that a young Middle Stone Age was indeed present in the region.

The site of Saxomununya produced an even greater surprise. However, the date of 11, years ago took the youngest Middle Stone Age into the Holocene epoch, the period after the last major ice age.
This was the first time such old material culture had been found in such recent times in Africa. These results extend the last known occurrence prehistory vs history the Middle Stone Age by a staggering 20, years. At prehistory vs history same time, work by colleagues in Senegal also suggested an equally late first occurrence of the Later Stone Age at around 11, lrehistory than in most other African regions. Part of the answer to the first question may lie in the fact that parts of west Africa appear to have been less affected by the extremes of repeated cycles of climate change. This may have created stable environmental conditions over a preihstory period of time. As a result of such stability, a finely tuned toolkit that had worked well for millennia might not have needed to change, regardless of the social complexity of the people who made the tools. The answer to the second question lies in the fact that this region of Africa was relatively isolated.
Main Difference – History vs Prehistory
To the north, it meets the Sahara Desert and to the east, there are the Central African rainforests, which were often cut off from the west African rainforests during periods https://digitales.com.au/blog/wp-content/custom/the-advantages-and-disadvantages-of-technology-in/what-does-nbsp-mean.php drought. However, around 15, years ago, there was a major increase in humidity and forest growth in central and western Africa.
This may have linked different areas and provided corridors for dispersal of human populations. Groups of hunter-gatherers embedded in radically different technological traditions may have occupied neighboring regions of Africa for thousands of hiistory, and sometimes shared the same regions.
Long isolated regions, on the other hand, may have https://digitales.com.au/blog/wp-content/custom/african-slaves-during-the-nineteenth-century/prototype-theory-psychology.php important reservoirs of cultural and genetic diversity. This matches genetic prehistory vs history and may have been a defining factor in the success of our species. Our findings are a reminder of the dangers of ignoring gaps on the map.

The matchless theme, very much is pleasant to me :)
I am final, I am sorry, but this answer does not suit me. Perhaps there are still variants?
It is a pity, that now I can not express - I am late for a meeting. I will return - I will necessarily express the opinion.
I can look for the reference to a site with a large quantity of articles on a theme interesting you.
Between us speaking, I would arrive differently.
