Evidence of Evolution

List and explain 3 examples of evidence of evolution. Support your answers with at least one picture. 
This assignment is worth 10 points. 
1. Fossils are a great example of evolution you can look back at different kinds of species and see how they changed.

2. Relative Dating: is the science of determining the relative order of past events, without necessarily determining their absolute age. Comparing the ages of rock layers found above and below the fossil layer. The layer determines how old the thing mite be.

3. Homologous structure: is the existence of shared ancestry between a pair of structures, or genes, in different speciesA monkey can have the same size and type of hand that a human has, since Humans evolved from monkeys.

4. DNA: Deoyribonucliec acid is a molecule that  the genetic instructions used in the development and functioning of all known living organisms. You can sort of tell what exact species that the animal or human came from by looking at the DNA of that human or animal.

5. Embryology: The science of the development of an embryo from the fertilization of the oveam to the featis stage.
