Classification

Why is it important to have a common classification system in the worldwide scientific community? It –

• It refers to organisms using detailed illustrations and diagrams rather than words
• It provides a system for translating names between language
• It provides a name, in Latin, that all scientists can use consistently.

Which of the following levels of classification is the largest, most inclusive group of organisms?
