Evidence of Evolution

What is extinction?

• Extinction is the end of an organism or a group of organisms, often due to inability to adapt.

• Extinction is the process of an organism evolving into a new species.

• Extinction refers to the temporary disappearance of a species from its habitat.

• Extinction is when an organism migrates to a different environment.

What is the impact of habitat loss on species?

• Habitat loss can lead to decreased populations and increased risk of extinction.

• Habitat loss has no significant effect on species populations.

• Habitat loss improves the living conditions for remaining species.

• Habitat loss increases biodiversity in the affected area.

What is a common ancestor?

• A species that has no descendants.

• A species from which two or more different species have evolved.

• A species that is extinct and has no relation to current species.

• A species that is the most recent ancestor of all living organisms.

What is natural selection?

• A process where all organisms survive equally regardless of their traits.

• A mechanism by which organisms better adapted to their environment tend to survive and produce more offspring.

• A theory that suggests all species are static and do not change over time.

• A method of breeding animals to enhance desirable traits.

What is a positive aspect of artificial selection?

• It ensures that human-preferred traits are available in animals and plants.

• It increases genetic diversity in species.

• It eliminates all genetic disorders in organisms.

• It allows for faster evolution in wild populations.

What is the significance of similar bone structures in different species?

• They indicate a common ancestor and support the theory of evolution.

• They show that species have adapted to different environments.

• They suggest that species are unrelated and evolved independently.

• They are a result of random mutations without any evolutionary significance.

How can environmental changes affect a species?

• Environmental changes can lead to extinction if a species cannot adapt to new conditions.

• Environmental changes have no impact on species survival.

• Environmental changes always benefit species by creating new habitats.

• Environmental changes only affect plant species, not animals.

How does genetic variation affect evolution?

• It has no impact on evolution.

• It provides the raw material for natural selection.

• It decreases the chances of survival.

• It leads to uniformity in species.

What happens to a population if it cannot adapt to a changing environment?

• It may thrive and grow.

• It may face extinction.

• It will migrate to a different area.

• It will become more diverse.

What is genetic variation?

• Genetic variation refers to the differences in DNA among individuals within a population.

• Genetic variation is the process by which organisms adapt to their environment.

• Genetic variation is the study of how traits are inherited from parents to offspring.

• Genetic variation refers to the similarities in DNA among individuals within a population.
