Richard G. Klein
Richard G. Klein (born April 11, 1941) is a Professor of Biology and Anthropology at Stanford University. He is the Anne T. and Robert M. Bass Professor in the School of Humanities and Sciences. He earned his PhD at the University of Chicago in 1966, and was elected to the National Academy of Sciences in April 2003. His research interests include paleoanthropology, Africa and Europe. His primary thesis is that modern humans evolved in East Africa, perhaps 100,000 years ago and, starting 50,000 years ago, began spreading throughout the non-African world, replacing archaic human populations over time. He is a critic of the idea that behavioral modernity arose gradually over the course of tens of thousands, hundreds of thousands of years or millions of years, instead supporting the view that modern behavior arose suddenly in the transition from the Middle Stone Age to the Later Stone Age around 50-40,000 years ago.

Middle Stone Age
The Middle Stone Age (or MSA) was a period of African prehistory between the Early Stone Age and the 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. 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 Paleol ...

La Ferrassie
La Ferrassie is an archaeological site in Savignac-de-Miremont, in the Dordogne department, France. The site, located in the Vézère valley, consists of a large and deep cave flanked by two rock shelters within a limestone cliff, under which there is a scree slope formation. Age Artifacts found at the site are the productions of Mousterian (300,000-30,000 BP), Aurignacian (45,000–35,000 BP), and Périgordian (35,000–20,000 BP) cultures. The cave area contains Gravettian (32,000–22,000 BP) objects and the scree contains objects from all these ages as well as the Châtelperronian The Châtelperronian is a proposed industry of the Upper Palaeolithic, the existence of which is debated. It represents both the only Upper Palaeolithic industry made by Neanderthals and the earliest Upper Palaeolithic industry in central and sou ... (35,000-29,000 PB).

Prehistory
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
François Bordes
François Bordes (December 30, 1919 – April 30, 1981), also known by the pen name of Francis Carsac, was a French scientist, geologist, archaeologist, and science fiction writer. Biography He was a professor of prehistory and quaternary geology at the Science Faculty of Bordeaux. He decisively renewed the approach of focusing on prehistoric lithic industries, introducing statistical studies in typology and expanding the use of experimental flint knapping. He was known among archaeologists throughout the world for his ability to replicate ancient stone implements; his technique was showcased in a photo essay in the "Early Man" volume of the Life Nature Library. He also published many science fiction novels under his pen name. In the USSR the science fiction of Carsac was very popular. He was translated and published into Russian as well as Romanian, Bulgarian, Lithuanian, Latvian, Hungarian, Estonian amongst others. However, no translations into English have existed ...

Recent African Origin Of Modern Humans
In paleoanthropology, the recent African origin of modern humans, also called the "Out of Africa" theory (OOA), recent single-origin hypothesis (RSOH), replacement hypothesis, or recent African origin model (RAO), is the dominant model of the geographic origin and early migration of anatomically modern humans (''Homo sapiens''). It follows the early expansions of hominins out of Africa, accomplished by '' Homo erectus'' and then ''Homo neanderthalensis''. The model proposes a "single origin" of ''Homo sapiens'' in the taxonomic sense, precluding parallel evolution in other regions of traits considered anatomically modern, but not precluding multiple admixture between ''H. sapiens'' and archaic humans in Europe and Asia. ''H. sapiens'' most likely developed in the Horn of Africa between 300,000 and 200,000 years ago, although an alternative hypothesis argues that diverse morphological features of ''H. sapiens'' appeared locally in different parts of Africa and converged du ...

Cro-Magnons
Early European modern humans (EEMH), or Cro-Magnons, were the first early modern humans (''Homo sapiens'') to settle in Europe, migrating from Western Asia, continuously occupying the continent possibly from as early as 56,800 years ago. They interacted and interbred with the indigenous Neanderthals (''H. neanderthalensis'') of Europe and Western Asia, who went extinct 40,000 to 35,000 years ago; and from 37,000 years ago onwards all EEMH descended from a single founder population which contributes ancestry to present-day Europeans. Early European modern humans (EEMH) produced Upper Palaeolithic cultures, the first major one being the Aurignacian, which was succeeded by the Gravettian by 30,000 years ago. The Gravettian split into the Epi-Gravettian in the east and Solutrean in the west, due to major climate degradation during the Last Glacial Maximum (LGM), peaking 21,000 years ago. As Europe warmed, the Solutrean evolved into the Magdalenian by 20,000 years ago, and these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
