If species A and B have very similar genes (DNA sequences) and proteins, what is probably TRUE?

• species A and B share a relatively recent common ancestor

• species A evolved independently of species B for a long period

• species A is younger than species B

• species A is older than species B

According to this cladogram, birds are LEAST related to -

• Amphibians
• Sharks
• Ray Finned Fish
• Crocodiles

Individuals that are well adapted to their environment will survive and produce:

• Fewer mutations

• Stronger genes

• More offspring

• More traits

Which trait do only humans have, according to the cladogram?

• jaws

• mammary glands & hair

• terrestrial during all life stages

• opposable thumbs

The study of the past and present geological distribution of species and the patterns that emerge from such analysis.

• Common Ancestry
• Biogeography
• Stasis
• Sequential

The closest evolutionary relationship most likely exists between the....

• human and gorilla
• horse and zebra
• human and chimpanzee
• chimpanzee and gorilla

Peppered moths can have either a light wing color or a dark wing color. A scientist studied populations of both light and dark peppered moths over a 10-year period. A graph of the data he collected is shown. Based on the graph, which is the best conclusion to make about changes in the moth populations by the end of the study period? 

• A disease has affected only the dark winged peppered moth. 
• At present, wing color is not a factor in the success of peppered moths. 
• A new food source has become available only to the light winged peppered moth. 
• At present, dark-winged peppered moths are being naturally selected for survival.
