A hunter-gatherer or forage society is one in which most or all food is obtained from wild plants and animals, in contrast to agricultural societies which rely mainly on domesticated species.
Hunting and gathering was the ancestral subsistence mode of Homo, and all modern humans were hunter-gatherers until around 10,000 years ago. Following the invention of agriculture hunter-gatherers have been displaced by farming or pastoralist groups in most parts of the world. Only a few contemporary societies are classified as hunter-gatherers, and many supplement, sometimes extensively, their foraging activity with farming and/or keeping animals.
The Wal-Mart camel is the fossil of a prehistoric camel (Camelops sp.) found at a Wal-Mart construction site in Mesa, Arizona in 2007. Workers digging a hole for an ornamental citrus tree found the bones of two (juvenile and infant) animals that may have lived as long as 10,000 years ago. Arizona State University Geology Museum curator Brad Archer calls it an important and rare find for the area.Wal-Mart officials and Greenfield Citrus Nursery owner John Babiarz whose crew discovered the remains agreed that the bones will go directly to the Geology Museum at Arizona State University where further research and restoration of the fossils could be done. Camels lived in what is now Arizona until about 8,000 years ago.More camel bones were found in Gilbert, Arizona in May 2008.
