Why is it important to learn about the diversity of life?

• To understand biological evolution

• To classify plants only

• To focus on extinct species

• To ignore evolutionary distances

What is a significant challenge in estimating the number of species?

• Lack of interest

• Many species are yet to be discovered

• All species are already known

• Species are easy to classify

What is the significance of understanding evolutionary distances?

• It is irrelevant

• It helps in understanding biological evolution

• It focuses on extinct species

• It is only for marine life

What is a probable outcome for many unknown species?

• They will thrive

• They will become extinct before discovery

• They will be easily classified

• They will dominate ecosystems
