Found: A Batch of DNA Molecules That Seem To Have Originated in Space

In what appears to be seriously big news from a  team of NASA-funded researchers, scientists have found evidence that  some building blocks of DNA–including two of the four nucleobases that  make up our genetic code–found in meteorites were created in space,  lending credence to the idea that life is not homegrown but was seeded  here by asteroids, meteorites, or comets sometime in Earth’s early  lifetime.This is big news, of  course, because if the ingredients for life were brought here from some  external source, there’s always the possibility that the same thing has  happened elsewhere in the universe–possibly many times over.
Scientists have been extracting fragments of DNA from meteorites for  decades now, but there was never really hard proof that those pieces of  biological molecules were native to the extraterrestrial object rather  than terrestrial contamination that occurred when the object slammed  into Earth. So while the idea of DNA riding aboard extraterrestrial  objects has been floated before, this is the first time we’ve been  presented real evidence backing that notion.

    I thought this was already known. I remember a few years ago reading that the Coal Cloud could have a chunk of DNA...
