GS Paper: GS Paper III – Science & Technology | Biodiversity Conservation
Tagline: When the past walks again, the future must listen carefully.
🔍 Key Highlights
🧬 What Was the Dire Wolf?
- Scientific Name: Aenocyon dirus
- Extinct around 12,500 years ago
- Roamed North America as a top predator
- Larger and more muscular than modern grey wolves
- Preyed on horses, bison, and other megafauna
- Extinction linked to climate change, prey loss, and human activity
🧪 The De-Extinction Process
- Led by Colossal Biosciences (Texas, USA)
- DNA sourced from:
- A 13,000-year-old tooth
- A 72,000-year-old skull
- Genome reconstruction based on ancient DNA
- Closest modern relative: grey wolf
- Used CRISPR gene-editing and cloning techniques
- Traits like size, fur density, and jaw strength were targeted
🐶 Birth of the New Ancients
- First pups: Romulus & Remus (October 2024)
- Third pup: Khaleesi (January 2025)
- Born via surrogate dog mothers
- Now raised in a 2,000-acre secure conservation facility
- Display solitary and aloof behaviours—unlike modern canines
⚖️ Scientific and Ethical Debates
- DNA match: ~99.5% with grey wolves
- Are they truly dire wolves or something new?
- Concerns:
- Behavioural authenticity
- Survivability in the wild
- Animal welfare and ecological consequences
🔭 Future Aspirations
- Colossal plans to revive:
- The woolly mammoth
- The dodo
- These experiments redefine what is “possible”
- Critics warn against romanticising resurrection without long-term safeguards
🧠 Technological & Ecological Impact
- May revolutionise conservation biology
- Could assist in ecosystem restoration
- Raises key questions:
- What is natural evolution now?
- Who decides what returns—and why?
🧠 Concept Explainer: Why This Matters
De-extinction, once fiction, is now testable reality.
While science revives lost sounds, ethics must anchor the direction.
Not every return is a rescue. Sometimes it is a revelation of what we still do not understand.

💭 A Thought Spark — by IAS Monk
“Once they roamed,
then they vanished—
now they whisper back
in code and howl
in the language of light.”
