18-2 Modern Evolutionary Classification ............................................Name________________________________

1. See Fig 18-6--- Based on appearance alone, which is more similar:
[ barnacles and limpets] or [ barnacles and crabs] (underline pair)

2. What is phylogeny?
_____________________________________________________

3. The strategy of grouping organisms based on their evolutionary history is called ______________________ classification.

4. Based on evolutionary classification, which pair is more similar:
[ barnacles and limpets] or [ barnacles and crabs] (underline pair)

5. Name two characteristics that barnacles share with crabs: _________________________________________

6. Characteristics that appear in recent parts of a lineage but not in its older members are called ____________________________ characters.

7. What is a cladogram? __________________________________________________________________

8. Name a gene that both humans and yeast both have: ___________________________________________
9. This gene is evidence that humans and yeast share a common ______________________________________

10. What peculiar behavior is found only in storks and american vultures? _______________________________

11. DNA evidence indicates that the american vulture is more closely related to a stork than to an ______________________________________

12. A ______________________ clock is used to estimate the length of time that two organisms have been evolving independently.

13. This model relies on measuring the number of ________________________ that have occurred in DNA.
