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.
Israel Finkelstein
According to Finkelstein's Low Chronology, the Iron Age I lasted until the middle of the 10th century BCE, while the Iron IIA is dated between the middle of the 10th century and ca. 800 BCE, if not slightly later. This means that the Megiddo palaces and other features which had traditionally been attributed to the time of King Solomon – features which date to the late Iron IIA – should indeed be associated with the endeavors of the Omride Dynasty in the first half of the 9th century BCE. A big debate ensued. Starting in the late 1990s, the focus of the discussion shifted to the interpretation of radiocarbon determinations for organic samples from key sites, such as Tel Rehov and Megiddo. All in all, the radiocarbon results put the Iron I/IIA transition ca. the middle of the 10th century (rather than 1000 BCE as had traditionally been proposed), and the Iron IIA/B transition in the early days of the 8th century (rather than ca. 925 BCE).
