How Scientists Study Evolution Essay

A description of how scientists in this area of study do their work
There are a few way to how scientist study evolution, which are fossils, DNA, homologous and anatomical. Fossils are great records which provide photographs of the past, bones, teeth, shells and imprints of animals and plants. Fossils provide answers to the changes of species and plants and what life was like more than four billion years ago. By using methods like relative and radiometric dating the can find out the age of the fossil, which helps fill the gaps to the knowledge of how species changed over time. DNA, which is also called Deoxyribonucleic Acid, is very helpful for evolutionist because DNA is the blueprint for all inherited characteristics for a living thing. Scientists have found way to see and map out genomes of lots of species and even use computers to compare the …show more content…
One of the main way scientist try and prove the theory of evolution is thought anatomical, the similarities between different organisms. By showing how the body parts of one kind of species resembles the body parts of another species, for example an ant’s leg and a dog’s leg or an eagle’s wind and a moth’s wing. Also scientists look at the structures of animals that have changed and adapted to survive and scientists compare the structures to unrelated species which is a useful way to back up evidence of evolution. Another way scientist study their work is, Homology, which is about the biology, it is about the development of different kinds of species based upon their common evolutionary ancestor. Scientist look at similar structures and functions of different species, for example a bats wings, human’s arm, whale’s flipper and dolphin’s flipper all these animals have the same arrangement of bones in one way or another,
