Elephant Evolution and Tusklessness

What is the main reason for the increase in tuskless female elephants in certain areas?

• Climate change

• Natural disasters

• Poaching and trophy hunting

• Habitat loss

How does natural selection favor tuskless elephants in poaching areas?

• They have better access to food

• They are less likely to be hunted

• They live longer

• They are more attractive to mates

What is the relationship between tusks and teeth in elephants?

• Tusks are unrelated to teeth

• Tusks are a type of bone

• Tusks are a type of horn

• Tusks are modified teeth

Why do researchers compare elephant genes to human genes?

• Humans and elephants have similar habitats

• Humans and elephants have similar lifespans

• Humans and elephants share a genetic program for building teeth

• Humans and elephants have similar diets

What is the purpose of collecting blood samples from elephants in Gorongosa?

• To measure their health

• To track their movements

• To study their diet

• To analyze their DNA

What is the significance of finding genetic differences in tusked and tuskless elephants?

• It shows the migration patterns of elephants

• It reveals the diet of elephants

• It indicates the age of elephants

• It helps in identifying the cause of tusklessness

How does the researcher describe the process of evolution?

• A process only occurring in the past

• An ongoing process influenced by humans

• A static process

• A historical event

What personal experience does the researcher share about working with elephants?

• It was a challenging experience

• It was a routine task

• It was a special and significant experience

• It was a disappointing experience

What role did Dominique play in the research project?

• She collected blood samples

• She identified individual elephants

• She was the project manager

• She analyzed DNA sequences

What is the significance of the 65-year-old female elephant mentioned in the transcript?

• She survived a period of high mortality

• She was the largest elephant in the park

• She was the oldest elephant in the park
