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.
Medieval archaeology
Medieval archaeology is the study of humankind through its material culture, specialising in the period of the European Middle Ages. At its broadest, the period stretches from the 5th to the 16th century and refers to post-Roman but pre-modern remains. The period covers the upheaval caused by the fall of the Roman Empire and cultures such as the Vikings, Saxons, and Franks. Archaeologists often specialise in studying either the Early Middle Ages (Migration Period) or the High Middle Ages and Late Middle Ages, although many projects and professionals move across these chronological boundaries. The rich nature of the medieval written record has meant that archaeology has often been seen as the "handmaiden to history", especially in the later medieval period. Analysis of material culture may enrich or call into question written evidence from the medieval period and the two sources of evidence need to be used together. Medieval archaeology has examined the development of medieval settlements, particularly the development of medieval towns and castles. It has also contributed to understanding of the spread and development of Christian monasticism during the medieval period.
