Yeah, even though they just induced bacteria in a lab to use Arsenic in their DNA, it's still a big discovery in the search for extra terrestrial life (if we ever find some that is). It shows that life needn't be in a form exactly like us, that life can potentially exist in other forms.

This has always been pretty obvious though....ok maybe they didn't have proof before but still!

Something can't be obvious if there's no proof.

Isn't there no proof that alien life exists?  Most people would say it's obvious though.
