The Middle Stone Age (or MSA) was a period of African Prehistory between Early Stone Age and Late 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. It was once considered roughly equivalent to the European Middle Paleolithic, but recent discoveries of evidence for art and symbolic culture in the MSA have forced a reassessment of this idea. 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.

Famous quotes containing the words middle, stone and/or age:
“Unpleasant questions are being raised about Mother’s Day. Is this day necessary? . . . Isn’t it bad public policy? . . . No politician with half his senses, which a majority of politicians have, is likely to vote for its abolition, however. As a class, mothers are tender and loving, but as a voting bloc they would not hesitate for an instant to pull the seat out from under any Congressman who suggests that Mother is not entitled to a box of chocolates each year in the middle of May.”
—Russell Baker (20th century)
“I’m coming home. I remember your saying when I left that people were dying and that I was crapping around with fate to come here. You were more right than you could imagine.”
—Judith Rascoe, U.S. screenwriter, Robert Stone (b. 1939)
“Our good schools today are much better than the best schools of yesterday. When I was your age and a pupil in school, our teachers were our enemies.
Can any thing ... be more painful to a friendly mind, than a necessity of communicating disagreeable intelligence? Indeed it is sometimes difficult to determine, whether the relator or the receiver of evil tidings is most to be pitied.”
—Frances Burney (1752–1840)
