Instructions
1. Download the “Assessment 4 Worksheet.” Begin working on the worksheet after reading
through this document.
2. Citations must follow the guidelines in the “course materials” D2L content folder:
“Literature Citation Requirements.”
3. Feel free to use your notes while working on this assessment.
4. Point values are provided in the rubric.
5. Students can discuss with each other only their research approach. Do not send drafts
of this assessment to each other or copy answers. Once this document is submitted to
the corresponding D2L assignment folder, it is automatically uploaded to Turnitin and
checked for plagiarism, including copying websites, the video, or your peers.
a. Turnitin produces a similarity score and we use that score to indicate which ones
to check further for plagiarism
b. There is not a set similarity percentage that indicates plagiarism. The similarity
will depend on the length of the answers and if the questions are restated in
those answers.
6. Save the document as a Microsoft Word® document. If you do not have Microsoft
Word®, then please see the “Start Here” folder in D2L for information on how to obtain a
free copy of it from MSU.
7. Submit the Word document to the Assignment folder titled “Assessment 4.”
Overview
For this assessment, students will be creating a phylogenetic tree of the candidate species and
closely related species. This will be part of an investigation to determine if there is a possible
surrogate species.
What is a Surrogate Species?
To bring a species “back” from extinction an embryo carrying the genetic information of the
extinct species needs to be implanted into a mother so that it can develop. For some species,
the mother may also provide parental support for the offspring. This mother is referred to as the
“surrogate.” Surrogacy typically takes place in a controlled environment. Your candidate species
is now extinct. Is there an appropriate surrogate for that species? If so, which species is it and
why? The first step in answering this question is to determine which species are closely related
to the candidate species. Therefore, for this assessment, students will create a phylogenetic
tree.
Part 1: Finding Species
1. Record your de-extinction candidate species in the worksheet.
2. Go to the IUCN Redlist site for your species. Scroll down to the section titled
“Taxonomy.” Record the taxonomic information in the worksheet.
3. The taxonomic rank of Genus is the most exclusive of these ranks. That means species
within the same genus are very closely related. The first search you should make to find
a surrogate is to search the same genus within the IUCN list. Do this now.
a. If you find one or more additional species in your search, then select the first one
on the list for your surrogate.
b. Click on this species; is any information available on the IUCN site?
c. If so, then you’ve found one potential surrogate.
d. If not, go back to the list and click on the next species in the list.
e. Repeat this until you have five species with some information.

f. If you exhaust the “genus” species list, then skip down to step #4.
g. Record the common name and scientific name of the species in the worksheet.
Include the five that have some information. Note that scientific names are
always italicized.
h. Skip down to section “Part 2: Determining Relatedness” if you have five species.
4. Now, if you do this original Genus search and no other species are found (or you do find
other species, but no information is available), then go to the next most exclusive
taxonomic rank, which is Family. Species within the same family are closely related but
not as close as those species within the same genus. However, a species from the same
family will do just fine. Do this now.
a. As above, select the first species on the list and determine if there is any
information.
b. Repeat this until you have five species with some information (or go to the next
taxonomic ranking, which is order, or select a closely related order).
c. Record the common name and scientific name of the species in the worksheet.
Note that scientific names are always italicized.
Part 2: Determining Relatedness
5. The first part of determining how closely related the species are is considering the
taxonomy, which you discovered in Part 1. For instance, if some of the species are in the
same genus while others are in the same family, then those in the same genus are more
closely related to each other than those in a different genus. If you chose more than one
species outside the candidate’s genus, then check to see if the genus of those species is
the same or different. If they have the same genus, then they are more closely related to
each other than the candidate species. If it is different then their relatedness cannot be
determined just by the genus.
6. The next step is to identify the species (or a closely related species) on One Zoom,
which is an interactive phylogenetic tree.
a. Once on the website, click on the “Explore” tab and select the appropriate
taxonomic group or “all complex life.”
b. Then either explore the tree to find your species or type the family or genus
name in the search textbox in the upper-right corner of the webpage.
c. If your species are not listed, then make a prediction of their relatedness based
on similar species that you find on One Zoom.
7. Complete the following in the worksheet.
• On the worksheet, 1) describe the predicted relatedness of the six species in
words (like the descriptions in the class activity) and 2) describe the process that
you used to determine their relatedness.
• There are six species total (the five closely related species and the candidate
species). If they are all the same genus and not on One Zoom, then it is okay to
just use shared derived characteristics to predict their relatedness.
• Note that this part is simply how they are related (e.g., species A is more closely
related to species B than species C, and so on). It is not why they are related.
Part 3: Identifying Characteristics
8. Create a rough sketch of the phylogenetic tree of the six species- do not include it in the
worksheet at this point.
9. Predict four shared derived characteristics of different clades.
• Use information from the IUCN Red List or other sources to determine this.
Consider physical and behavioral characteristics, if available.

Recall that habitat is not a characteristic, but physical characteristics suitable for
types of habitats may be shared derived characteristics.
• Refer to the online prep for the definition of “shared derived.”
8. Create a final version of the phylogenetic tree.
a. Include the six species and the four characteristics.
b. Create either a diagonal or squarish-corner tree style (for descriptions of these
styles, see the week 14 original coursepack activity). Do not copy directly from
One Zoom (screenshot or redrawn).
c. Feel free to either hand-draw it neatly and take a photograph or create it using a
program, such as Microsoft PowerPoint ® and then save the slide as an image.
Paste the image in the worksheet.
Part 4: Surrogate Species
9. After creating the phylogenetic tree, reflect on which species is the most suitable
surrogate species and to what extent that species is a suitable surrogate. Consider
evolutionary relatedness, shared derived characteristics, and IUCN conservation status
(i.e., endangered, least concern, etc.). Type a reflective paragraph in the worksheet that
provides your conclusion (which species and how suitable of a surrogate it would be)
and evidence supporting your conclusion.
