It is completely impossible to tell how typical or atypical our
origin and history are without having access to at least one,
preferably multiple samples which originated outside of common causal 
origin. The solar system is probably insufficient, unless we have clear
evidence of multiple independant origins within this very
system (improbable due to crosscontamination).

Right, we're looking for someone we can relate to, or at least
look upward to.
