The article provides a detailed list of 25 extinct animals, including the Tasmanian Tiger, Woolly Mammoth, Dodo, Passenger Pigeon, and the Mexican Grizzly Bear, among others, explaining the reasons behind their extinction.
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
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.
This past year scientists and conservation organizations declared that a long list of species may have gone extinct, including dozens of frogs, orchids and fish. Most of these species...
An animal is considered extinct when the last remaining member of its species dies out and there is not a single individual left on Earth. Causes of extinction might include an epidemic, extreme climate changes, loss of food sources, and destruction of their natural habitats.
From a Galapagos tortoise to one black rhino subspecies, these 11 species have been declared extinct or possibly extinct over the past half-century.
WWF is committed to saving endangered species. Learn more about the species we are working to protecting from becoming endangered or extinct.
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.
Extinction is the death of all members of a species of plants, animals, or other organisms. One of the most dramatic examples of a modern extinction is the passenger pigeon. Until the early 1800s, billions of passenger pigeons darkened the skies of the United States in spectacular migratory flocks.
Humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences.
