 Arctic fact archaeology and arctic fact, or arctic fact, is something made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, however, the word has become the term of particular nuance and is defined as, an object recovered by archaeological endeavour, which may be a cultural artifact having cultural interest. However, modern archaeologists take care to distinguish material culture from ethnicity, which is often more complex, as expressed by Carol Kramer in The Dictum Pots Are Not People. Examples include stone tools, pottery vessels, metal objects such as weapons, and items of personal adornment such as buttons, jewelry and clothing. Bones that show signs of human modification are also examples. Natural objects, such as fire-cracked rocks from a garth or plant material used for food, are classified by archaeologists as eco-facts rather than as artifacts. From the point of view of ethnography and archaeology, an ancestral artifact can be defined as any object of natural raw material-chert, obsidian, wood, bone, native copper, and so on made by a people following a lifestyle based on foraging e.g. hunting, gathering hand slash or basic agriculture or pastoralism e.g. horticulture, transhumans.
