Elephant Evolution and Conservation Issues

The video explores the concept of evolution, focusing on how elephants in Mozambique have evolved to become tuskless due to poaching pressures. It explains natural selection and how human activities can accelerate evolutionary changes. The video highlights the importance of conservation efforts to protect elephants and ensure their survival.

What was the initial observation made by the documentary maker about elephants?

• Elephants were migrating to new areas.

• Elephants were becoming more aggressive.

• Elephants were growing larger in size.

• Elephants were losing their tusks.

What is the basic idea behind the theory of evolution?

• Only animals evolve over time.

• Only plants evolve over time.

• All living things change over time.

• All living things remain the same over time.

How does natural selection contribute to evolution?

• By preventing any changes in organisms.

• By making all organisms identical.

• By allowing only the strongest to survive.

• By adapting organisms to their environment.

Why did some elephants in Mozambique become tuskless?

• Due to a genetic mutation.

• Due to climate change.

• Because of a change in diet.

• As a result of poaching pressure.

What was the impact of the civil war on Mozambique's elephant population?

• It increased the elephant population.

• It had no effect on the elephants.

• It caused elephants to migrate to other countries.

• It led to a significant decrease in the population.

What is surprising about the evolution of tuskless elephants?

• It only affected male elephants.

• It was caused by a natural disaster.

• It occurred very rapidly.

• It happened over millions of years.

What are some functions of elephant tusks?

• They are used for flying.

• They help in swimming.

• They help in communication.

• They are used for defense and digging.

What potential problem arises from the lack of tuskless males?

• It might lead to increased migration.

• It could result in more aggressive behavior.

• It might cause an imbalance in the gender ratio.

• It could lead to a shortage of food.

What is necessary for the long-term survival of elephants?

• Increasing their population rapidly.

• Feeding them artificially.

• Leaving them alone and protecting them.

• Introducing them to new habitats.

What role does human impact play in the evolution of species?

• It slows down the process of evolution.

• It has no effect on evolution.

• It accelerates rapid changes in the environment.

• It prevents any evolutionary changes.
