De-Extinction and Its Implications

The video explores the discovery of a preserved Woolly Mammoth and the concept of de-extinction, which aims to bring extinct species back to life. It discusses methods like cloning, genetic reconstruction, and back breeding, highlighting challenges and ethical concerns. The potential benefits, such as filling ecological niches and learning opportunities, are also considered.

What was the significant discovery made by Russian researchers in 2013?

• A living Woolly Mammoth

• A frozen dodo bird

• A new species of dinosaur

• A perfectly preserved Woolly Mammoth carcass

What is the term used for bringing extinct species back to life?

• De-extinction

• Reincarnation

• Reanimation

• Rejuvenation

Why is it impossible to bring back dinosaurs like in Jurassic Park?

• Dinosaurs are not related to any living species

• Dinosaurs are too large to clone

• DNA degrades over millions of years

• There are no dinosaur fossils left

Which method was used to attempt the revival of the Pyrenean Ibex?

• Artificial selection

• Cloning

• Back breeding

• Genetic reconstruction

What is a major challenge in cloning a Woolly Mammoth?

• Elephants ovulate too frequently

• Lack of intact frozen cells

• Finding a suitable surrogate

• Mammoth DNA is too different from elephants

What is a potential problem with resurrected species?

• They might become too intelligent

• They might be too aggressive

• They could suffer from poor genetic variation

• They would not survive in modern climates

Why might reintroducing extinct species be problematic?

• They might not recognize humans

• They could cause global warming

• They might not reproduce

• They could become invasive

What is one potential benefit of de-extinction?

• Reducing global temperatures

• Increasing human population

• Filling ecological niches

• Creating new habitats

How could de-extinction technology help living species?

• By making them larger

• By making them more intelligent

• By changing their diets

• By preserving them from extinction

What is a reason some people find de-extinction exciting?

• It could create new forms of entertainment

• It allows for the study of ancient species

• It might lead to time travel

• It could lead to new food sources
