This category lists some of the species that have become extinct due to human activity, whether intentionally or unintentionally. If a more specific reason is known, the species should also be assigned to a subcategory of Category:Species by threat. They may also need to be placed in Category:Extinctions since 1500.
In scientific terms, it is “functionally extinct” because the only two of the species left in the world are both female, and only one is of an age that it can act as a surrogate or have its ...
A factor that exacerbated their decline to extinction was the flocking behavior that led them to return to the vicinity of dead and dying birds (such as birds downed by hunting), enabling wholesale slaughter. [40] The final extinction of the species in the early years of the 20th century is somewhat of a mystery, as it happened so rapidly.
A species is declared extinct after exhaustive surveys of all potential habitats eliminate all reasonable doubt that the last individual of a species, whether in the wild or in captivity, has died. [15] Recently extinct species are defined by the IUCN as becoming extinct after 1500 CE. [1]

In a single lineage, when an old chronospecies (A) is judged to have changed into a new species (B) by anagenesis, the old species is deemed phyletically extinct. Pseudoextinction (or phyletic extinction) of a species occurs when all members of the species are extinct, but members of a daughter species remain alive. The term pseudoextinction ...
