extant

Extant is an adjective meaning still in existence. It is commonly used to describe living beings or things that have survived to the present, as opposed to those that are extinct. In scientific writing, extant contrasts with extinct and is frequently applied in biology, paleontology, and archaeology when distinguishing current species or populations from those known only from fossils or historical records. The term is widely used in taxonomy, biodiversity studies, and conservation discussions to indicate what remains of the natural world today.

In biology and conservation, extant species are those that have living representatives today. Researchers track extant diversity to understand evolutionary relationships, assess ecosystem health, and prioritize species or habitats for protection. The term helps frame discussions about extinction risk, habitat loss, climate change, and conservation planning by highlighting what has persisted into the present.

Extant also refers to a contemporary cultural work: the 2014 American science fiction drama television series created by Mickey Fisher. The series stars Halle Berry as Molly Woods, an astronaut who returns from a long mission and becomes entangled in a mystery at the intersection of biology and technology. It aired on CBS and was noted for its exploration of themes such as motherhood, ethics in genetic science, and the implications of space exploration.
