A caveman is a popular stylized characterization of what early humans or hominids may have looked and behaved like. The term is sometimes used colloquially to refer to Neanderthals or to Homo sapiens of the Neolithic era, although popular descriptions of cavemen are usually highly inaccurate.
The term has been discouraged for a number of reasons. Neither Neanderthals nor early humans actually lived in caves, however paleolithic humans were responsible for cave art. Also from a political correctness standpoint, the term "cavemen" implies that only males were important. The term still lives on as an icon in the minds of many, and is seen in many items of popular culture. Examples include the comic stripsB.C. and Alley Oop, and the cartoonThe Flintstones.
Cavemen are usually portrayed as being hairy, clothed in animal skins, armed with clubs, unintelligent, and aggressive. They are often shown as living contemporaneously with dinosaurs, a situation not supported by archaeological evidence.
Einstein born into cavemen would make a difference I feel, but not the average man. We are cavemen with the advantage of a more intellectual environment.
Cavemen, or primitive man, didn't quite have the happy go lucky day to day existence that you might perceive from the teachings in school.
The majority if their day would be taken up with activities, such as hunting, eating, tending the group, scouting, gathering edible vegetation, looking after the children etc. The tedious tasks required to stay alive in the harsh environment take up all the time given in a day (apart from cave painting, apparently, the lazy slobs).
