Extinction of Species

The video explains extinction, the process by which species cease to exist. It discusses how evolution and adaptation affect species survival, with some species becoming extinct if they cannot adapt to environmental changes. The concept of living fossils, species that have remained unchanged for millions of years, is introduced. The video also covers mass extinction events, such as the K-T extinction that wiped out the dinosaurs, and the current alarming rate of species extinction. It emphasizes the importance of stopping habitat destruction and adopting sustainable practices to mitigate this crisis.

What does it mean for a species to become extinct?

• It becomes endangered.

• It evolves into a new species.

• It stops existing entirely.

• It migrates to a new habitat.

According to the theory of evolution, why do some individuals survive better than others?

• They are more aggressive.

• They have better-suited characteristics for their environment.

• They are larger in size.

• They reproduce more frequently.

What are living fossils?

• Newly discovered species.

• Fossils found in living organisms.

• Species that have remained unchanged for millions of years.

• Species that have gone extinct.

What was the most famous mass extinction event?

• The Permian extinction.

• The Triassic extinction.

• The K-T extinction event.

• The Cambrian explosion.

What is a key strategy to slow down the current rate of extinction?

• Introducing more invasive species.

• Lowering our carbon footprint.

• Promoting habitat destruction.

• Increasing urban development.
