Exemplar Problems

Question:

Discuss the role of extinction in the process of evolution. How does it impact biodiversity?

Answer:

Extinction is the disappearance of a species from Earth. It is a natural part of the evolutionary process and can occur due to various factors, including environmental changes, competition with other species, and catastrophic events. Extinction impacts biodiversity by removing species from ecosystems, which can have cascading effects on other species and the overall balance of the ecosystem. It also creates opportunities for new species to evolve and fill ecological niches previously occupied by extinct species. Additionally, studying extinct species through the fossil record provides valuable insights into the history and patterns of evolution.
