Comets Probably Didn't Seed Life on Earth | Science Made Simple

Discover how University of Cambridge scientists tested whether comets could have delivered life's building blocks to early Earth. Learn why small comets break up in the atmosphere, why fast, steep impacts destroy most hydrogen cyanide (HCN), why successful delivery averaged zero in their models, and why Mars looks slightly more promising — while stressing this does not definitively rule comets out.
