The Neanderthal Man lived in Europe, North Africa, the Near East and parts of Asia during the period from about 100,000 to 35,000 years ago. The Neanderthal stage is a stage intermediate between the stages of Homo erectus and modern man.
Neanderthal Man was discovered in 1848 from Rock of Gibraltar but it went unnoticed. In 1856, Neanderthal Skeleton was again discovered from Neanderthal valley in Dusseldorf, Germany. In its true sense, the term Neanderthal is restricted for the people of fourth glaciation living in Europe, Near East and Central Asia.
Judging from the anatomical features of Neanderthal, Ernest A. Hooton divided them into two types- Classical and Progressive. La Chappelle-aux-Saints, La Moustier, La Quina, La Ferrassie are some of the members of the classical group while the progressive type is represented by Ehringsdorf, Krapina, Steinheim, Tabun, etc.
The Neanderthal Man flourished during the Mousterian (Mid-Palaeolithic) period, which corresponds to the last glacial invasion. The flora and fauna found in association with the skeletal remains indicate a very moist and cold climate. Woolly rhinoceros, woolly mammoth, reindeer are the typical fauna of the period.
A change in tool type is also noticed during this period. The Mousterian culture is represented by points and scrapers of various designs and similar other artifacts.
Characteristics of Classical or Conservative Neanderthals (La Chappelle-aux-Saints):
- It was discovered in 1908 in a cave in Correze district, France.
- The age of the fossil has been estimated to be upper Pleistocene and the culture is Mousterian.
