the process of evolution involves a series of natural changes that cause species to arise, adapt to the environment, and become extinct. all species or organisms have originated through the process of biological evolution.evolution occurs when there is change in the genetic material. evolution does not change any single individual, it changes the inherited means of growth and development.

the evidence for human evolution in this time line includes climate change, species, and milestones in becoming human.

the layers that contain fossils and archaeological clues can be dated by more than a dozen techniques that use the basics of physics,chemistry, and earth sciences. some techniques can estimate the age of the ancient teeth and bones directly.

genes offer evidence of how closely we are to one another. species connection with all other organisms.

scientists have discovered evidence concerning human evolution the evidence comes in many forms. thousands of human fossils  enable researchers and students to study the changes that occurred in the brain and body size. these fossils alow students and researchers to study their diet, other aspects to how life was as an early human species over the past 6 million years. millions of stone tools help the researchers find figure paintings, foot prints, and other traces of human behavior. advances in the dating of fossils and artifacts help determine the age of those remains.
