Summary: This week we learned about how scientists find the common ancestor of an organism. There's actually multiple ways such as comparative anatomy and a cladogram. Comparative anatomy is when scientists check the bones of an organism and compare it to the bones of another organism. If they have a similar bone structure or they have a bone that's the same then they could both have come from the same common ancestor. A cladogram is similar except it doesn't just to bones it also does hair and embryos. A cladogram is similar to a graph and a scientist would use this to compare traits of multiple organisms and would see which organisms were most related.
SP4: Analyzing and interpreting data
Scientific investigations produce data that must be analyzed in order to derive meaning.
Did you create a graph, table, drawing, etc. of the data you obtained in an experiment?
Yes because we used a cladogram to see who was most related to a T-rex and we used a graph to record our data.
