Evidence of evolution 1. Fossil Records 2. Geographical Distribution 3. Embryology

Work Step by Step

1. Fossils are located in chronological order in sedimentary rock. Fossils closer to the surface more closely resemble organisms today. This shows evolution has occurred. 2. When looking at the geographical distribution of organisms in the past and present, it can be seen that organisms will diverge and become different species. This shows evolution has occurred. 3. Some species look oddly similar when they are an embryo. This shows common ancestry.
