Quote:Much to the science team's bewilderment, every life form they examined could easily have been an undiscovered species of terrestrial origin. They used the same amino acids, the same proteins, even the same base-pairs for DNA. The team was forced to the uncomfortable realization that either an astronomically unlikely coincidence had taken place, or all life on Gwynedd shared the same source as life on Earth.
As per space-opera general rule #75, most life in the galaxy unless it's like really weird will share the same basic chemical structure. Not always 100% identical but close enough that even a 100% match wouldn't be that disconcerting. So, yeah.
However! I have a potential solution if you're interested. What if instead of simply Gwynedd life sharing a source the lifeforms are actually adapted from Earth life from somewhere like say, somewhere around this period? That's far enough back for adaptation to create some interesting new things but close enough for a naturalist to say "hey, wait a minute..."
