Download You should be on Primer #4, “How Does Evolution Really Work?” IF

Today we are applying information to the real world regarding both micro and macro-evolution. Using your device, watch
each video clip and answer the accompanying questions using complete sentences! Your teacher will have you submit this
through Canvas or in paper format, so wait for instructions! If possible, please use earbuds so you can listen without
disturbing others. If you have no earbuds, please keep the volume at a reasonable level.

You should be on Primer #4, “How Does Evolution Really Work?” IF you are NOT, from the right hand, drop
down menu and select: “How does evolution really work?”
1) What are the 4 sub components involved in natural selection?
2) What does each mean? (answer this one above)
3) What is the trait the scientist is studying in the video?
4) Why do organisms tend to produce more offspring than can survive?
5) What is another term to describe the scenario where not all organisms produce the same number of offspring who do
survive?
6) What is competition? What does it have to do with fitness and survival?
7) The scientist says “natural selection allows for things like longer beak, etc to form.” Is this actually correct or an over
simplification? Why?
8) Use a ruler to look at how long 2 mm is. Does it surprise you that something so small can have such large effect on
survival? Why?
9) Based on what you said in #8, does it always take huge genetic changes to influence survival of an organism?
10) What do survivors do that influences the entire population?
11) What is meant by “overtime the entire population” changes?
12) How does the entire population gain an adaptation?
13) How can the scientist compare the DNA of multiple hummingbirds’ to compare whether the DNA is similar or different
between groups?
14) What type of gene map would the scientist have to run if he wants to see difference in base pairs between birds?
15) If mutation drives some birds to have different beak length and I compare the type of map you identified in #14
between birds with different beak length, what will I see?
16) Why is natural selection the most important force in evolution?
And from the right hand, drop down menu, watch: “Why does evolution matter now?”
17) What is a microbe? Give an example.
18) How do we determine if a microbe like bacteria is “helpful” or “harmful” to us?
19) Do bacteria evolve? What is your support for your answer?
20) Why is the theory of evolution an important theory in for doctors and the field of medicine?
21) Tuberculosis has become more lethal, using micro-evolutionary processes, explain how.
22) How does the evolution of bacteria affect the way illnesses and treatments are approached?
23) So, based on what you watched in the video, give one specific example of evolution.
Now watch “How do we know evolution happens?”
24) What type of evidence for evolution were the scientists using?
25) How did scientists use the fossils to determine what type of animal the fossil was? (How did they figure out it was not a
whale or deer?)
26) If you find out that the flipper of a whale, arm of a monkey, wing of a bird and limb of a frog all share common
anatomy, what is the most logical explanation for these similarities?
27) What was the major discovery made?
28) Name 5 ways that the organism that they studied could have changed genetically over time.
Now go to and watch the video: http://media.hhmi.org/biointeractive/interactivevideo/pocketmousequiz/
29) What is the trait being studied in the mice?
30) As you watch, answer the embedded questions, keep track of all questions and anything you miss and don’t know why!
Now watch this crash course mini-lecture (review) at: https://www.youtube.com/watch?v=aTftyFboC_M
(Close ads as soon as they pop please) Once you are done watching the “crash course” using 3 specific examples of
illustrations from the video, write a conclusion paragraph “micro-evolutionary process gives organisms diversity so that
when macro-evolutionary process occur, the population can withstand those changes successfully.”
