The field involves an understanding of the similarities and differences between humans and other species in their genes, body form, physiology, and behavior.Paleoanthropologists search for the roots of human physical traits and behavior.Humans and the great apes (large apes) of Africa -- chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas -- share a common ancestor that lived between 8 and 6 million years ago.Humans first evolved in Africa, and much of human evolution occurred on that continent.Early human fossils and archeological remains offer the most important clues about this ancient past.These remains include bones, tools and any other evidence (such as footprints, evidence of hearths, or butchery marks on animal bones) left by earlier people.Archeological evidence refers to the things earlier people made and the places where scientists find them.
Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
Usually, the remains were buried and preserved naturally.
They are then found either on the surface (exposed by rain, rivers, and wind erosion) or by digging in the ground.
They entered Europe somewhat later, between 1.5 million and 1 million years.
Species of modern humans populated many parts of the world much later.
Paleoanthropology is the scientific study of human evolution.
