What is the difference between clovis and pre clovis peoples

Typically about four inches long and a third of an inch thick, they were sleek and often beautifully made. After discovering Clovis points in New Mexico, Howard and others looked for traces of them in collections of artifacts from Siberia, the origin of the first Americans. None have ever been found.

Clovis points, it seems, were an American invention—perhaps the first American invention. More than 10, Clovis points have been discovered, scattered in 1, locations throughout most of North America; Clovis points, or something similar, have turned up as far south as Venezuela.

They seem to have materialized suddenly, by archaeological standards, and spread fast. The oldest securely dated points, discovered in Texas, trace back 13, years. In a few centuries they show up everywhere from Florida to Montana, from Pennsylvania to Washington State. Care must be taken: Dating stone objects is difficult, and the results are subject to controversy the timeline here is from a widely cited article in Science by Michael R.

Stafford Jr. They reported their findings last week in Nature. Based on a genetic analysis of 52 modern Native American groups and 17 Siberian groups, the researchers concluded the majority of Native Americans descend from a single Siberian population. Arctic people who speak Eskimo-Aleut languages also inherited about half of their genetic material from a second wave of Siberian immigrants. Members of a third migration contributed to the gene pool of Na-Dene -speaking Chipewyans of Canada.

Finding multiple migrations complements previous genetic, archaeological and linguistic studies. The researchers only looked at the ancestry of living Native Americans. What is known about the Clovis people comes from the remains they left behind, which are mostly tools: scrapers, drills, blades, and distinctive leaf-shaped, fluted spear points called Clovis points.

The exquisite four-inch-long projectile points, carefully chipped from flint, chert, and obsidian, have concave grooves down each side, sharp edges, and a lance-shaped tip. More than 10, Clovis points have now been found in North America from southern Canada to Central America, all dating from the same time.

The oldest points, found in Texas, date to 13, years ago, while points found northern Mexico are approx. Researchers say that the Clovis culture swept across the continent in less than a thousand years, allowing native peoples to successfully live in different environments. Stone tools are more easily preserved than organic remains like clothes, sandals, and blankets, so little is known about the Clovis people except for what archeologists infer from the artifacts that have been found.

What we do know is that they were undoubtedly nomadic people, roaming from place to place in search of food and living in crude shelters and tents or in shallow caves. Researchers have found five types of Clovis sites in North America—single kill sites, multiple-event kill sites, campsites, cache sites, and isolated artifacts.

Clovis kill sites with spear points and isolated finds like an arrowhead in a cornfield are commonly found, while campsites with hearths and cache sites with stone tools are rare. Carbon 14 dating at the Blackwater Draw site shows that the Clovis people lived in the area for about years, hunting animals that drank at a spring-fed lake and marsh, building campfires, and even digging a well, the first known water control system in North America.

Later ancient people dug as many as 20 other wells here between 4, and 10, years ago. Beyond this evidence, nothing is known about the Clovis diet, what kind of clothes they wore, what they looked like, or their cosmology.

Only one burial has been found, an infant associated with stone tools and bone tool fragments dated to 12, ago in Montana. DNA analysis of the bones revealed that the infant is an ancestor of modern Native Americans. It appears that post-glacial climate changes, including a 1,year cold period, as well as the disappearance of the large animals possibly due to an asteroid impact in Canada , forced native peoples to adapt, move to other places, and invent new technologies to survive. Researchers say other post-Clovis cultures like the one discovered at Folsom in northern New Mexico derive from the Clovis.

The Clovis culture irrevocably changed Native American life in a short time span, flashing across North America with new and improved technologies that allowed people to flourish across the continent.

Better spear points and arrowheads lashed onto wooden shafts were coupled with notched throwing sticks, called atlatls, which allowed people to efficiently hunt game. The Clovis tool kit allowed quick dismembering of animal carcasses and butchering the flesh at kill sites. The nomadic Clovis lifestyle, using hunting and foraging to obtain food, lasted thousands of years after the disappearance of the Clovis culture, a tradition that continued into historic times with Plains tribes hunting bison on the plains of eastern New Mexico.

The area has changed dramatically since Clovis times, with a drier climate and the surface of the ground now 15 feet higher than it was thousands of years ago. A self-guided trail explores the quarry, with a large shed protecting excavations from weather and a smaller shed over the Clovis hand-dug well.

Before visiting the site, stop at the Blackwater Draw Museum at Eastern New Mexico University in Portales five miles to the south and learn about the Clovis culture and the discovery and excavation of the Blackwater site.

The vegetation consisted of spruce forest interdispersed with tundra which it gradually replaced.

This landscape was similar but not identical to the modern subarctic transition zone. The trees, shrubs, and grasses served as food sources for grazing and browsing mammals, including mammoth , mastodons , giant bison, horses, muskoxen , and caribou that could be hunted by early Native groups.
