Click Play Mission 1 (Contains 3 parts)
You will read facts about each organism by clicking the magnifying glass on one of the organisms (look at the top green wording). Then drag them to the center to create a phylogenic tree based upon the traits that they share. Then you will drag the traits (small dots) to the place on the tree. If it is correct you will see it at the top of the organism. All dots on each organism must be filled correctly to move on.
Mission 1 Part 1: Red, Green, and Gecko (Draw the simple tree below)
1. Is an animal or plant more closely related to a fungus?
2. Draw the simple tree
Mission 1 Part 2: Familiar Faces
(Sometimes it is helpful to fill in a chart before drawing the tree. Put an x or check for the traits that each organism has and then try drawing tree).
Hint: amniote means egg with an amniotic membrane, basically reptiles, birds, and mammals
3. Fill in this table
4. Draw the tree
Mission 1 Part 3: Tree of Life Vegetarian Edition
6. Make your own chart and phylogenetic tree and fill it in
7. Draw the tree.
8. What is the question at the end and what was your answer:
Mission 2 Part 1: Eating Dinosaurs for Dinner
9. Draw the Phylogenetic Tree
10. Do birds have anything in common with dinosaurs?
If yes, what do they have in common?
Mission 2 Part 2: One Small Step
11. Draw the Phylogenetic Tree
12. What is the first trait that helped aquatic species evolve into creatures that live on land?
13. How do we know which animals can go on land in this list?
Mission 2 Part 3: Origin of Whales
From now on, if you want to make a chart, do it on your own paper. If you notice that not doing a chart is slowing you down, then do one.
14. Which of the following species does not have tail flukes?
15. Which trait was not used in this cladogram/phylogenetic tree?
16. Which organism would be considered the outgroup? Why?
Mission 3 Part 1: Frog Legs and Fish Eggs
Now you will be looking at DNA and will need to click on the strand.
17. Draw the tree below.
18. The DNA sequence of the West Indian Ocean coelacanth is closest to which species?
Mission 3 Part 2: One Fish, Two Fish, Red Fish, Lungfish
19. In 2013, scientists found that coelacanths are not the closest relative of four-footed amphibians and other animals. Which species is?
20. Which organism would be considered the outgroup? Why?
Mission 3 Part 3: Where the Tiny Wild Things Are
21. Why was examining DNA better than considering physical traits?
