A history of the cro magnon in human evolution

Found during construction, the rock shelter contained a large cavity that protected the fossils. The date of the fossils has been placed at approximately 32,000 years ago to 30,000 years ago, during the uppermost Pleistocene Kreger 2005, Smithsonian 2007.

EARLY MODERN HUMANS (CRO-MAGNON MAN)

Located were skeletons of three adult males, one adult female, and one infant. This appears to be a deliberate burial site, with body adornments found with the skeletons, such as pieces of shell and animal tooth in apparent pendants or necklaces Kreger 2005, Smithsonian 2007. The type specimen from this find is Cro-Magnon 1, an adult male specimen.

Also known as the "Old Man," Cro-Magnon 1 has a complete cranium except for the teeth and mandibular condyles Kreger 2005. The skeletons showed the same high forehead, upright posture and slender gracile skeleton as modern humans.

Neanderthal

The cranial capacity is estimated at 1,600 cubic centimeters. Other specimens have since come to light in other parts of Europe and in the Middle East. Cro-Magnon behavior From the initial findings, it would appear that these early humans cared for one another to help survive the physical hardships of life.

The type specimen shows evidence of a fungal infection, several individuals had fused vertebrate indicative of traumatic injury, and the adult female had survived for some time with a skull fracture Smithsonian 2007. Given the life threatening nature of these injuries, it is believed that Cro-Magnons exhibited community support and took care of each other's injuries, as well as practiced the ritual of burial Smithsonian 2007. Cro-Magnon's are believed to have had a varied and balanced diet, including meat, grain, wild carrotsbeets, onionturnip and other foods.

  • But population levels never dropped enough for humans to start losing their technological and symbolic innovations;
  • Ancient modern humans created paintings and sculptures, wore jewelry, made musical instruments and used dozens of different kinds of implements including tools to make tools;
  • Cut marks on the skull indicate the the skin, muscles and blood vessels were removed and lines were scraped on the skull, probably with an obsidian tool;
  • He or she, since researchers can't tell the sex from the skull bones would have lived about 200,000 years ago, according to researcher Erik Trinkaus, of Washington University in St.

Surviving Cro-Magnon artifacts include huts, cave paintingscarvings, and antler-tipped spears. The remains of tools suggest that they knew how to make woven clothing. These early humans used manganese and iron oxides to paint pictures and may have created the first calendar around 15,000 years ago Whitehouse 2000. The flint tools found in association with the remains at Cro-Magnon have associations with the Aurignacian culture that Lartet had identified a few years before he found the skeletons.

The Cro-Magnons are assumed to have come into contact with the Neanderthalsand are often credited with causing the latter's extinctionalthough morphologically modern humans seem to have coexisted with Neanderthals for some 60,000 years in the Middle East, near the Mediterranean Sea Bar-Yosef and Vandermeersch 1993and for more than 10,000 years in France Gravina 2005. Cro-Magnons appear to be associated with the "Great Leap Forward. Different populations of humans begin to create novelty in existing technologies.

Artifacts such as fish hooks, buttons, and bone needles begin to show signs of variation among different population of humans, something that has not been seen in human cultures prior to 50,000 BP.

  • Numerical supremacy must have been an overwhelming factor that allowed modern humans to outcompete their larger rivals;
  • This appears to be a deliberate burial site, with body adornments found with the skeletons, such as pieces of shell and animal tooth in apparent pendants or necklaces Kreger 2005, Smithsonian 2007;
  • Instead, increasing population densities in Africa may have made it easier for people to keep in contact with neighboring groups, possibly to exchange mating partners;
  • Archeological remains at the Tategahana Paleolithic Site at Lake Nojiri have been dated as early as 47,000 Years before present.

This speed-up of cultural change seems connected with the arrival of modern humans, Homo sapiens sapiens. Theoretically, modern human behavior is taken to include four ingredient capabilities: Among concrete examples of modern human behavior, anthropologists include specialization of tools, use of jewelry and images such as cave drawingsorganization of living space, rituals for example, burials with grave giftsspecialized hunting techniques, exploration of less hospitable geographical areas, and barter trade networks.

Debate continues whether there was indeed a "Revolution" leading to modern man "the big bang of human consciousness"or a more gradual evolution.

Thus, the probable original meaning is "great cavity. See also References Bar-Yosef, O.
