Question

Using the picture below of the triangles and pentagon answer this question: 2.a) Identify potential Synapomorphies aka "Shared Derived Characters": To pick informative characters, look for things that are shared between two or more members of the ingroup. Give a DETAILED description of each of the characters you are going to use. This is important, as often two characters are very similar (see example on the next page). Remember, they should be binary (i.e., one of two states--black or white, two eyes or four eyes). They should not be subjective (i.e., long vs. short). You can always identify the ancestral state of your character by asking if the outgroup shows the character of interest. Answer this completely and correctly. Do not use previous answers/versions of answers.

A
Pentagon = Outgroup
Triangles = Ingroup--all triangles are more closely
related to eachother than any are to the pentagon
