(iv) The fossil bones of the human ancestors are embedded in the earth's layers.
(v) Palaeoanthropologists and archaeologists excavate the soil and rock layers on the earth and extract evidence about human ancestors.
(vi) These layers and the fossils are scientifically dated to study the various stages in human evolution and prehistory.
(vii) Through the gathered evidence they attempt to understand the evolution of human history and developments in a chronological order.·
(viii) The earth was formed approximately 4.54 billion years ago.
