All prehistoric skeletal remains of humans that are archeologically earlier than the Neolithic (necessarily an imprecise limit), regardless of degree of mineralization or fossilization of bone, and regardless of whether the remains may be classed as Homo sapiens sapiens (anatomically modern humans). In this sense, the term “humans” is used broadly to mean all primates related to living people since the last common ancestor of people and African apes, thus all species currently included in the genera Homo, Australopithecus, Ardipithecus, and Paranthropus (and potentially others discussed below).
