watch a movie and anwser questions
“Part 1. Directions: Please watch the movie
Your Inner Fish
(https://www.biointeractive.org/classroom-resources/your-inner-fish).
The movie has accurate captions, if you wish to use them. You must watch the movie to answer the questions. Be warned-we will know if you google the answers. You are not allowed to use google docs to write this with other students. You may watch the movie together, but you may not work together to answer the questions. You need to paraphrase your answers-no credit will be given to students who copy the movie subtitles. This is considered plagiarism. If there is any evidence of copying off of another student or any other academic dishonesty, you will receive a zero and the issue will be brought to the university academic dishonesty board.”“Answer the questions using the text boxes provided below each question
.Upload the file through turnitin (on Canvas) using a PDF or a Word File only.”
1. “The theory of evolution is supported by many lines of evidence. This
video discusses many of these lines of evidence (paleontology,
embryology, genetics, etc.) Please summarize 3 different types of
evidence found in paleontology, embryology, and genetics that support
the idea that humans are descended from fish (meaning, describe the
scientific discoveries). No fewer than 3-4 full sentences. 3pts.”
2. “Neil Shubin and his team describe a number of variables that they
consider when identifying where to hunt for early land animals. List
and describe (as in, why do we need to identify these variables) two of
these variables in complete sentences. 2pts.”
3. “ Tiktaalik
has many features that classify it as a “transitional fossil”.List
and describe at least 3 of these features. In your answer, describe
why these features are considered transitional. 3pts.”
4. “What does Sonic the Hedgehog (the gene, not the video game) do?
Explain what can happen if the gene isn’t activated enough or it is
activated too much-give an example of this. 2pt.”
5. “These fossils were found in the Arctic, in Greenland, where it is very
cold and snowy through most of the year. However, their environment
when they were alive 470 million years ago was not cold and snowy. Explain. This isn’t discussed in the movie-you have to think about it
geologically. 2pt.”
6. “Write a paragraph (4-5 sentences) on what you found interesting
about this movie, or what you learned. Feel free to ask any questions
you have about the movie. 2pts.”
“Part 2. Lecture material questions.”
1. “The Cambrian Explosion and the Great Ordovician Biodiversification
event both resulted in major expansions of diversity on Earth. However,
the types of diversity were very different. Explain two differences
between the two, in terms of the types of diversity evolving during the
events. I would warn heavily against googling the answers for this-use
your lecture notes. 4pts.”
2. “The following questions relate to the phylogenetic tree below. Note
that the branches are square shaped instead of v-shaped. The tree can
be read in the exact same way. 2pts.”
a. “What organism is the sister group to
all symmetrical animals?”
b. “Who is sister group to the chordates?”
c. “Mollusks have two shells. Lophophorates have two shells,
though they are constructed differently and made of different
minerals. Is this homology or homoplasy?”
d. “Why might bilateral symmetry have evolved (use your class
notes)?”
3. “Using the below C
13
diagram, answer the following questions.”
a. “The amount of C
13
in the rock record indicates what about
photosynthetic activity? Be specific; mention high and low C
13
.
2pts.”
b. “In the Phanerozoic, there is a large decrease in C
13
at about 250
million years ago. What might the climate have been like during
the decrease, knowing what you know about C
13
(discuss both
temperature and photosynthetic activity in your answer)? 2pts.”
