Should We Revive Dinosaurs? Exploring De-Extinction | Charvi Thanakanti | TEDxYouth@AllianceAcademy

TL;DR

Scientists are reviving extinct species through cloning and genetic engineering.

Transcript

Transcriber: Mônia Correia Eller Reviewer: Walaa Mohammed Here's two sheep. The sheep look very similar but there is one difference between them. One of them is a clone, and the other one is not. Can you guess which one is which? Did you make your guesses? The answer is the one on the left. So this is Dolly, the first mammal to ever be cloned. An... Read More

Questions & Answers

Q: What is de-extinction, and how is it achieved?

De-extinction is the process of bringing back extinct species through techniques like back-breeding, SCNT, and genetic engineering.

Q: What are some examples of successful de-extinction efforts?

Successful de-extinction efforts include the Bucardo goat and ongoing projects to revive the woolly mammoth, thylacine, and dodo bird.

Q: What are the pros of de-extinction?

De-extinction can restore ecosystems, increase genetic diversity, and contribute to scientific knowledge.

Q: What are the cons of de-extinction?

Challenges include the need for extensive resources, maintaining populations, and ethical considerations regarding the impact on existing species.

Summary & Key Takeaways

• Dolly the cloned sheep and the Heck brothers' attempt to revive the Aurochs illustrate different methods of de-extinction.

• De-extinction involves back-breeding, somatic cell nuclear transfer (SCNT), and genetic engineering techniques.

• Pros include ecosystem restoration and genetic diversity, while cons include resource limitations and ethical considerations.
