Question:
Name the levels of classification proposed by Linnaeus. What happens to similarities among organisms as we go from top to bottom level?
Answer:
Classification systems as proposed by Linnaeus use a hierarchical system in which organisms are placed into groups, at different levels, according to the features they share. These groups or levels are(from top to bottom):
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
Species is the lowest level in which group, we find the highest level of similarities and All members of a species are capable of interbreeding.
