Cockroaches can survive harsher environments... many can survive a nuclear blast and its aftermath... what would happen if we "seed" another planet with a ton of cockroaches? Do you think they would just die? Or..possibly...evolve into something alien? On that note...has that been attempted before? Are we an evolution of something that was dropped on this planet perhaps as a way to rid a far away world of their pests? Or maybe just as a scientific experiment? Is some alien species observing us for their scientific purposes?
Hmm....
