"You would not expect to see these nucleobase analogs if contamination from terrestrial life was the source, because they're not used in biology, aside from one report of 2,6-diaminopurine occurring in a virus (cyanophage S-2L)," said Callahan. "However, if asteroids are behaving like chemical 'factories' cranking out prebiotic material, you would expect them to produce many variants of nucleobases, not just the biological ones, due to the wide variety of ingredients and conditions in each asteroid."
So awesome! Life happens.
>Life happens.
That seems to be the trend. Everything we find is the result of basic physical principals, and what we do see elsewhere always appears repeated. -I don't see why life should be any exception. There's no good reason why life can't be the common result of environments that occur over and over again throughout the cosmos. Intelligence is probably an evolutionary niche that is probably exploited whenever possible too. These are exciting times. I can't wait until higher resolution studies of exoplanets start rolling in.
