Suppose a new species is created from a random mutation that happened during an instance of reproduction in an existing species. How can that new species survive and flourish if there only exists one of it's kind and therefore it's not able to reproduce? By definition a species can only reproduce with others of the same species, no? It seems to me the only way it could is if a mate is created due to a separate occurance of a similar mutation, and the chances of both mutations occurring at around the same point in timespace must be very close to zero. And even if it were to happen, it seems to me the offspring wouldn't be able to reproduce due to problems with inbreeding.

No honest informed person would define species in this manner.
This is a better analogy
