Question 14

Question 16

Match each model of life on earth in column 1 with its description in column 2.

Question Correct Match

Static Model      b. Species arise separately and do not change over time.

Separate types    c. Species do change over time and new species can arise, but each group of    species derives from a separate ancestor that arose independently.

Transformation    a. Species arise separately but do change over time to adapt to the changing environment.

Common descent    d.Species do change over time to adapt, and new species can arise. All species derive from a common ancestor.
