query: When was the Middle Stone Age?
passage: 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.[1] 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.[2] 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.[3] 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.[2]
passage: Archaeology of Northern Europe
Out of the Late Bronze Age Urnfield culture of the 12th century BCE developed the Early Iron Age Hallstatt culture of Central Europe from the eighth to sixth centuries BCE, which was followed by the La Tène culture of Central Europe (450 BCE to 1st century BCE). Albeit the metal iron came into wider use by metalsmiths in the Mediterranean as far back as 1300 BCE due to the Late Bronze Age collapse, the Pre-Roman Iron Age of Northern Europe started only as early as the 5th/4th to the 1st century BCE.
