Extinction is the termination of a taxon by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively.
2 days ago · Extinction, in biology, is the dying out or extermination of a species. It occurs when species are diminished because of environmental forces (natural or human-made) or because of evolutionary changes in their members. Learn more about mass extinctions and modern extinctions.

Feb 5, 2019 · Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.
May 29, 2019 · Extinction is a natural phenomenon: After all, more than 90 percent of all organisms that have ever lived on Earth aren’t alive today. But humans have made it worse, accelerating natural...
A mass extinction is a short period of geological time in which a high percentage of biodiversity, or distinct species — bacteria, fungi, plants, mammals, birds, reptiles, amphibians, fish, invertebrates — dies out.
Extinction is the complete disappearance of a species from Earth. Species go extinct every year, but historically the average rate of extinction has been very slow with a few exceptions. The fossil record reveals five uniquely large mass extinction events during which significant events such as asteroid strikes and volcanic eruptions caused ...
Extinction rates today are hundreds—perhaps thousands—of times higher than the background rate. They’re so high that scientists say we’re on the brink of a mass extinction.
Jul 12, 2018 · Extinction is a term applied to a known species, of which there are no known living individuals. Some species which have suffered extinction are known only from their fossilized remains. Others were at one point known to humans, but are gone now.
