Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

Population
14. A subset of a population colonizes a new area

Natural selection
Natural selection does not make perfect individuals
19. Invented the binomial method(naming of species); also believed that life was fixed

Reproductive fitness
21. Sometimes different species share common ancestors
Microevolution
