This is, of course, nothing more than Panspermia, but it is interesting in the idea that we might have sibling solar systems (relatively) nearby that could be seeded with very similar life. If we were to find this to be true it would be a great way to evaluate convergent evolution (presuming, naturally, we ever develop the ability to explore such systems in a meaningful amount of time).
