How can the human evolution be traced?


Open in App
Solution

Evolution: Evolution is the process of the development of new types of living creatures from the pre-existing ones as a result of the accumulation of genetic differences that occurred gradually with the pace of time.

The tools through which the evolution of human beings can be traced are:

  • Excavation- Archaeology is the study of human beings through the materials used by them or related to them. Excavation, or the process of finding out, processing, and keeping a record of archeological remains can show how human evolution has occurred.
  • Study of fossils- Fossils of earlier human beings and the animals having chances of being related to human beings help to learn about human evolution. It helps in learning what relation the humans and those animals had with each other.
  • Carbon dating- The age of the fossils and the archaeological remains of human beings can be learned through carbon dating. These ages can be helpful in studying the steps of the occurrence of human evolution.
  • Determination of DNA (deoxyribonucleic acid) sequences: From the remains of body parts of human beings or animals related to them, DNA has been studied. It let people learn about the genetic variations that have eventually led to evolution.
