Question 10

Natural selection requires all of the following EXCEPT:

Accepted Answer

All individuals must survive to reproduce

Question 11

Which of the following scenarios best illustrates speciation?

Accepted Answer

A population of finches becomes geographically isolated and evolves into distinct species over generations

Question 12

Which of the following is an example of evolutionary adaptation?

Accepted Answer

A population of insects develops resistance to a pesticide over generations

Question 13

Which of the following best explains how evolution accounts for both the unity and diversity of life?

Accepted Answer

Bacteria or Archaea

Question 17

Which of the following best describes the role of mutations in evolution?

Accepted Answer
