Answer 1

Answer:

the correct answer is C

Explanation:

Answer 2

B.The discovery of new species means that previously existing species became outdated.

• When scientists find new animals or species, the previous systems become obsolete due to the new and latest addition.
• The new species also has to be added to the classification. Thus, when new species are found, the new DNA or features also needs to be added to the classification.
• This requires and demands a complete change in the previously existing system.
• That is why the classification system of animals has changed over time.
