User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-4212769-20120302173919/@comment-3057194-20120309161445

a group of dogs is somehow split up. one group stays in its normal habitat and doesnt have to change. the other group somehow ends up in a very weird place, where they need to evolve. later the two (now seperate) species of dog meet again, turns out they can live in the same area (but cant reproduce anymore).

but loss is totally right about the rest
