Answer the following in detail:

The history of humans is closely related to the history of the earth. Elucidate.

The history of humans is closely related to the history of the earth. The geological, archaeological and biological records of historical times are contained in the upper layers of the earth. They help in reconstructing the history of the earth and of various living organisms. The fossil bones of the human ancestors are embedded in the layers of the earth.

Palaeoanthropologists (those who study human evolution through fossil remains) and archaeologists (those who study human evolution through material remains) excavate the soil and rock layers on the earth and extract evidence about human ancestors. These layers and the fossils are scientifically dated which helps us to study the various stages in human evolution and prehistory. Through the gathered evidence, they attempt to understand the evolution of human history and developments in a chronological order.

The earth was formed approximately 4.54 billion years ago. Conditions for the emergence of organisms were first developed followed by plants and animals. Finally, the foundation for the evolution of humans was laid down which help us to study the history of humans.
