Cambridge: Comets Probably Didn't Seed Life

Researchers at the University of Cambridge say comets probably didn't deliver life's building blocks to Earth. Most of them hit too fast and too steep for fragile organic molecules to survive, and their modeling says hydrogen cyanide arrived nowhere near enough to get chemistry going. Scientific Reports published the findings. Mars, with its thinner air, may have been a friendlier landing spot, though the team stresses that doesn't mean it happened. Don't count your chickens before they hatch. I've hauled enough hay to know a fast, steep arrival wrecks anything fragile, and I never once needed a grant to learn it. Meanwhile, somewhere a federal grant committee is already drafting a request to study the study, and it'll cost more than the comets ever did.
