What is directed panspermia?

What is directed panspermia?

• A. Rock or dust transferring microorganisms between planets within the same solar system
• B. Chloroplasts contain chlorophyll
• C. Organic molecules can form in a strongly reducing atmosphere
• D. Intelligent extraterrestrials purposely spreading seeds to other planets and solar systems

Answer: (D)

Directed panspermia is the idea that intelligent beings intentionally spread life to other planets or solar systems. It envisions an advanced civilization deliberately seeding worlds with microorganisms or life forms, rather than life arriving by chance or through natural processes alone. This differs from natural panspermia, where rocks or dust might transfer microbes between planets within a solar system, and from ideas about how organic molecules first form in planetary atmospheres. The other options describe broader or different concepts (natural transfer within a solar system, details about chloroplasts, or abiotic formation of organics) and do not capture the notion of purposeful, intelligent seeding.
