“In laboratory experiments, Callahan and colleagues showed how the
nucleobases could have formed inside meteorites. Simple chemical
reactions involving ammonia, water and hydrogen cyanide — all
ingredients found in meteorites — produced the wide range of
nucleobases the scientists found in the space rocks.”
If it was so simple--meteorites or asteroids could spontaneously
produce exotic nucleobases, why did Earth never form them? In fact,
most meteorites came from Mars via the Asteroid Belt:
