1: Comparative anatomy- Comparing body parts, look for similarity. Tigger's ancestors were cats and tigger and a cat have the same structures in their arms and in their legs.
2: People believed that the Jaguar and the Leopard share the common ancestry from Eurasia a little over 2 million years ago. The fossil record is a preserved remains and tracks of animals
4: Comparative embryology is comparing th appearances of the embryo in the earlier stages. Embryos grow and develop and different organisms become less and less simliar. Some ancestors used to have similar characteristics but the newer species evolve out of those certain characteristics. | For example, cats and Tiggers both have gills, lungs, 4 divided legs, and tails in the earlier stages. As time passes, the cat's tail becomes long and straight, and Tigger's tail becomes long and spiraled so he can bounce around.
5: Geographic distribution shows how species adapt and evolve into their environment. Different organisms evolve in all kinds of ways depending on their traits. | For example, Tigger lives in the woods because he needs space to bounce on his tail and a place with cool temperatures to live.
6: If you compare a lion and tigger there genes in their arms and legs are the same
7: comparative biochemistry- the study of differences in chemical processes among species used to study evolution
