NASA finds DNA components in meteorites, says they originated in space (video)

So, this can be kinda wild: scientists at NASA have uncovered new evidence that DNA components present in meteorites can originate in space, lending new credence to the speculation that life on the earth can have arisen from a pre-existing “kit” of fabrics delivered via asteroid. The invention is printed in a brand new paper from Dr. Michael Callahan, whose team of researchers closely analyzed samples from 12 different meteorites, using a mass spectrometer and liquid chromatagraph. Of their samples, they discovered traces of adenine, guanine, and a whole lot of molecules referred to as nucleobase analogs — including three which are rarely found on the earth. Scientists have long known that meteorites can contain DNA elements, but were unsure whether these materials actually originate in space. The presence of those three molecules, however, suggest that they do, potentially raising new questions on the dawn of life on the earth, and beyond. It is all quite heady, but steam ahead for a NASA video which may help clarify things, after the break.
