what is it called when someone comes back from the dead
Lazarus syndrome Lazarus syndrome, (the Lazarus heart) also known as autoresuscitation after failed cardiopulmonary resuscitation,[1] is the spontaneous return of circulation after failed attempts at resuscitation.[2] Its occurrence has been noted in medical literature at least 38 times since 1982.[3][4] It takes its name from Lazarus who, as described in the New Testament of The Bible, was raised from the dead by Jesus.[5]
Extinction In biology, extinction is the termination of an organism or of a group of organisms (taxon), normally a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence.
