Summary:
        Comparative analogy is when scientists compare different animals bone structure and their anatomy to see the similarities and differences. This is is something that shows things like common ancestors and it shows how closely related one animal is to another. The picture is showing how what the different bones are in animals and each color shows each part of the different animals like how humans and cats have fingers and a bat has longer finger type bones, while horses have a hoof, and more. In the picture the cat's arm looks closest to the human arm then anything else and that is showing how humans and cats are the closest to each other and could have a common ancestor. This is something that is to find the common an ancestors of animals and it is something to see how things are related.

SP 4: Analyzing and interpreting data:
        We made a graph this week to observe the similarities and differences in animals like T-Rex's and if they were extinct or things we would use the comparative analysis. We had to add a + or a - to show if the animal did or did not have a certain feature like hair and things but if we did not know like how we do not know if the T-Rex had hair we would put a question mark. The graph was to show the similarities and differences between animals. We also looked at the arm bones of different animals and color coated the bones to see what the bones were in one animal vs another. We did lots of different visuals and analysis of animals to find the similarities and differences.
