- A new Cambridge study challenges the long-held idea that comets delivered the building blocks of life to early Earth.
- Using computer simulations of more than 100,000 early comet impacts, researchers found that fragile organic molecules, including hydrogen cyanide, would usually have been destroyed by the heat and pressure of a high-speed impact.
- In most simulations no intact delivery happened at all, and the authors say a successful delivery would have been at best a rare fluke.

A new Cambridge study challenges the long-held idea that comets delivered the building blocks of life to early Earth. Using computer simulations of more than 100,000 early comet impacts, researchers found that fragile organic molecules, including hydrogen cyanide, would usually have been destroyed by the heat and pressure of a high-speed impact. In most simulations no intact delivery happened at all, and the authors say a successful delivery would have been at best a rare fluke. The findings, published in Scientific Reports, suggest life's ingredients may instead have formed on Earth itself or arrived by asteroids, which hit more gently and more often.
