Question

The fossil record is testament to extinct fauna no longer present on Earth. Certain areas of the planet have always had high species diversity (evidence from fossils and catalogs of current species diversity). Which of the processes listed below likely contributed to the patterns of animal diversity we see? extinction events (both local and global) the appearance of new land masses over time volcanic eruptions changes in atmospheric oxygen

Answer 1

Answer: Option (1)

Explanation:

The extinction event played an important role in the creation of new diverse life forms on earth. After an extinction event, both globally and locally, more than 75% of animal species gets vanish and the only those highly resistant life supporting organisms survive and with due course of time, they undergoes evolution, thereby bringing changes to the existing life forms. This is how they initiates and helps in the increasing species diversity.

Thus, the correct answer is option (1).
