Just as Jesus raised Lazurus from the dead, some animal species that were thought to be extinct are being sighted again. Here is a link that lists the top 10 species that have been rediscovered lately. However, because of the existence of the Lazarus species, there are also Elvis species, that is there are species that "impersonate" the great species that went extinct. To see some examples of Elvis species click here. The big question is, how can we distinguish the two apart? Are these Lazarus species zombies or are they simply just an adapted version of the original species?
