Question

how did Carl Linneaus original classification system differ from today?
a he only had two kingdoms, animals and plants
b he did not classify all the way down the species level
c he was a botanist, so he only classified plants
d he did not consider how organisms may be related to one another

Answer 1

Carl Linnaeus's original classification system primarily differed from today's system in that:

**a. He only had two kingdoms, animals and plants.**

Linnaeus’s system classified life into two kingdoms: Plantae (plants) and Animalia (animals). Modern classification includes a more complex hierarchy with multiple kingdoms (including Fungi, Protista, and others) and is based on evolutionary relationships, genetic data, and a more extensive understanding of biodiversity.

While options **b**, **c**, and **d** contain some elements of truth, they are not as significant as the difference in the number of kingdoms. Linnaeus did classify down to the species level, and although he was a botanist, he did classify animals as well. Additionally, his system did not incorporate modern evolutionary relationships, but this is somewhat inherent in the nature of his classification approach rather than a primary distinction of the system itself.
