What could help humans achieve  “de-extinction”, in other words, bringing extinct species back to life?（multiple choices）

• artificial intelligence

   (AI)

• data analysis

• nature conservation measures

• digital memory

According to the article, why is it unlikely that dinosaurs will be revived?

• Artificial intelligence cannot analyze dinosaur DNA.

• Their fossils have not been found.

• Dinosaurs went extinct too recently for de-extinction to be possible.

• Dinosaurs DNA cannot last forever.

What is the expected return date for the woolly mammoth from extinction according to Colossal Biosciences?

• 2050

• 2037

• 2027

• 2045

What does Robert Lanza suggest about the feasibility of bringing dinosaurs back to life?

• Dinosaurs can be cloned from fossils.

• Dinosaurs' DNA is too degraded for de-extinction.

• Dinosaurs will return within the next decade.

• Dinosaurs' remains are preserved in permafrost.

What is the primary objective of the Colossal Biosciences De-extinction Project?

• To study extinct species using advanced biotechnology.

• To restore balance to ecosystems by bringing extinct species back to life.

• To develop artificial intelligence for genetic engineering.

• To create digital memory of extinct species.
