Evidence of Evolution

1.) Fossils- When fossils are dug up the Archeologist they have to determine an age of it. So they take radioactive elements to get a better structure. Then ,if it has any, you can take DNA from the fossil to compare and analyze. You then can find close relatives to the fossil and see what some adaptations were made over time.

2.) Embryology- The study of embryos and their development. The earliest growth stage of an organism. When studying the embryo scientists can find if there are traits from the parents or if there are mutations.

3.) DNA- DNA is the molecule that controls heredity and directs the development of every organism. In a cell with a nucleus, DNA is found in genes that make up the chromosomes. Scientists take the DNA from the fossil and compare it to other DNA to find out the species of the animal.
