Closely related to sloths and anteaters, armadillos are a unique species with around 20 different subspecies. One variety, the Giant armadillo, is close to extinction in their wild habitats of South America.
Daughter species that evolve from a parent species carry on most of the parent species' genetic information, and even though the parent species may become extinct, the daughter species lives on. Extinction of a parent species where daughter species or subspecies are still extant is called pseudoextinction. In other cases, species have produced no new variants, or none that are able to survive the parent species' extinction.
