ANATOMY

Detailed explanation-1: -Extinction is defined as the end of an organism or of a group of organisms, normally a species. The moment of extinction is considered when the last individual of the species die, although their capacity to breed and recover may have been lost much before this point.

Detailed explanation-2: -The extinction of any species is an irreversible loss of part of the biological richness of the Earth. Extinction can be a natural occurrence caused by an unpredictable catastrophe, chronic environmental stress, or ecological interactions such as competition, disease, or predation.

Detailed explanation-3: -An endling is the last known individual of a species or subspecies. Once the endling dies, the species becomes extinct. The word was coined in correspondence in the scientific journal Nature.

Detailed explanation-4: -EXTINCT (EX)-A species is Extinct when there is no reasonable doubt that the last individual has died. A species is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual.

Detailed explanation-5: -Extinct species are those species that are no longer in existence. Example :-Dinosaurs and Dodo.
