Practice MCQs
Key Highlights
Colossal Biosciences' De-extinction Project
U.S. firm attempts to revive extinct species (e.g., woolly mammoth, dire wolf) using genome editing and cloning techniques.
Aim: restore ecosystems and combat climate change (e.g., grasslands absorbing methane).
Scientific Criticism and Credibility Gaps
Only 20 genes edited in dire wolf; output is a “strange-looking gray wolf” with no peer-reviewed validation.
Critics argue that such speculative projects divert attention and funds from urgent conservation of existing species.
Ethical & Resource Questions
Projects lack ecological oversight and risk being misused for marketing or nationalist propaganda.
Funding millions on gene revival while biodiversity continues to decline due to habitat loss is seen as misplaced prioritisation.
Analysis & Way Forward
Scientific efforts must focus on conserving current species and ecosystems rather than sensational resurrection experiments.
Clear ethical frameworks are needed for gene-editing and biotech in conservation.
Mains Mock Question:
"Do you think scientific de-extinction of species is a viable solution to current biodiversity loss and climate change? Critically examine its implications."
