Question
1.1
Open the “Detail” menu and set the detail to Stage 1. Zoom to Level 2 on the drop-down zoom level menu in the upper left-hand corner.
The diagram shows that life’s diversity is descended from a last common ancestor that lived nearly four billion years ago. Using information available in this figure, along with discussions in Chapters 25 and 26,indicate which of the following characters were present in that common ancestor. For a hint, open the “Filters” menu and select “Characteristics.”
A.
B.
C.

Question
1.2
Change the zoom and detail to Zoom Level 3 and Detail Stage 4. Then, under Filters, click on “Model Organisms” and “Characteristics.” Move the map so that you can see the tips of the plant and fungi branches. You can roll your pointer over the orange and green flags to see what each represents.
Chlamydomonasreinhardtii and Arabidopsis thaliana are both model organisms, widely used in laboratory research. What features do they share, possibly illuminating more general features of the plant clade?
A.
B.
C.
D.
E.
Correct.

Question
1.4
In the Filters menu, turn off the “Model Organism” and “Characteristics” filters. Set the zoom and detail levels to Zoom Level 3 and Detail Stage 8 and move the map so the amoebozoan branch is visible.
The amoebozoans are a clade of protists characterized by amoeba-like cell organization in some stage of the life cycle. They are most closely related to:

Question
1.5
Set the zoom and detail levels to Zoom Level 3 and Detail Stage 6, then open the Periods menu and click on “Ordovician.” (It may help to toggle back and forth to deeper zoom levels and more detailed stages.)
Imagine that you were transported back to the Ordovician Period, 485-444 million years ago. As you moved from one environment to another, you would notice some similarities and some differences relative to the modern biota. Which group of organisms would likely be most similar to its modern counterparts?
A.
B.
C.
D.
E.
Correct.
Incorrect.

Question
1.8
Now go to Zoom Level 4, Detail Stage 3.
Which group of plants also increased in diversity at approximately the same time as the angiosperms?

Question
1.9
Now zoom back out to Zoom Level 2, select Detail stage 11 and look at the branches that the insect branch has resolved into. Zoom in on the insect branches on Zoom Level 5 to see all of the branches and roll over the lines to see their names. Turn on the “Characteristics” filter in the Filters menu.
Which insect order does not undergo metamorphosis?
A.
B.
C.
D.
E.
Correct.
Incorrect.

Question
1.10
Recall from the book that wings evolved independently in insects, bats, and birds. Turn off the characters filter, zoom out to Zoom Level 2 on Detail Stage 5, and look at when these groups diverged by selecting different time periods in the Periods menu.
In which group did powered flight (e.g. wings) appear first?
