Into how many kingdoms did Carolus Linnaeus divide the living world?
Think it through first, then pick an option.
- a 2
- b 3
- c 4
- d 5
Answer and explanation
Correct answer: a 2
Linnaeus divided the living world into two kingdoms: plants and animals.
Why the other options are wrong
- b 3: Not three; Linnaeus's split had two kingdoms, plants and animals.
- c 4: Not four; from Linnaeus to the mid-twentieth century there were two kingdoms.
- d 5: The five-kingdom proposal was Whittaker’s (1969), not Linnaeus’s.
