Zoology 05: Taxonomy Lab/ Tree Building Exercise Group Members: Section 1. Name the organisms (be descriptive...don't just call them, Jim, Ted, Cathy, etc.) and carefully cut them out. Next, group your "organisms" together by how you think they're related. Simply do it by eye and intuition (like we did in the Phylostrat example). You can draw circles around groups that you think are most closely related to one another. Don't spend more than one minute doing this. Make notes below indicating what groups are related to what. This does not need to be specific.

Group Members:
Section
1. Name the organisms (be descriptive..don't just call them, Jim, Ted, Cathy, etc.) and carefully cut
them out. Next, group your "organisms" together by how you think they're related. Simply do it by
eye and intuition (like we did in the Phylostrat example). You can draw circles around groups that
you think are most closely related to one another. Don't spend more than one minute doing this.
Make notes below indicating what groups are related to what. This does not need to be specific.

2. Now we will re-run the exercise using principles of homology and shared ancestry to get the best
hypothesis we can of your organism's true ancestor-descendant relationships!
a) Identify potential Synapomorphies aka "Shared Derived Characters":
Characters are another name for "characteristics". Only, here you are hypothesizing that the
characters you choose are homologous (similar due to shared ancestry) between two or more taxa
and are therefore synapomorphies. 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.
