Middle Stone Age
The Middle Stone Age (or MSA) was a period of African prehistory between the Early Stone Age and the Later Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50–25,000 years ago. The beginnings of particular MSA stone tools have their origins as far back as 550–500,000 years ago and as such some researchers consider this to be the beginnings of the MSA. The MSA is often mistakenly understood to be synonymous with the Middle Paleolithic of Europe, especially due to their roughly contemporaneous time span, however, the Middle Paleolithic of Europe represents an entirely different hominin population, "Homo neanderthalensis", than the MSA of Africa, which did not have Neanderthal populations. Additionally, current archaeological research in Africa has yielded much evidence to suggest that modern human behavior and cognition was beginning to develop much earlier in Africa during the MSA than it was in Europe during the Middle Paleolithic. The MSA is associated with both anatomically modern humans ("Homo sapiens") as well as archaic "Homo sapiens", sometimes referred to as "Homo helmei". Early physical evidence comes from the Gademotta Formation in Ethiopia, the Kapthurin Formation in Kenya and Kathu Pan in South Africa.
Medievalism
In the 1330s, Petrarch expressed the view that European culture had stagnated and drifted into what he called the ""Dark Ages"", since the fall of Rome in the fifth century, owing to among other things, the loss of many classical Latin texts and to the corruption of the language in contemporary discourse. Scholars of the Renaissance believed that they lived in a new age that broke free of the decline described by Petrarch. Historians Leonardo Bruni and Flavio Biondo developed a three tier outline of history composed of Ancient, Medieval, and Modern. The Latin term "media tempestas" (middle time) first appears in 1469. The term "medium aevum" (Middle Ages) is first recorded in 1604. "Medieval" first appears in the nineteenth century and is an Anglicised form of "medium aevum".
