Extinction | Definition & Examples | Britannica

https://www.britannica.com/science/extinction-biology
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 - Wikipedia

https://en.wikipedia.org/wiki/Extinction
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. This difficulty leads to phenomena such as Lazarus taxa, where a

These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. If the low estimate of the number of species out there is true - i.e. that there are around 2 million different species on our planet** - then that means between 200 and 2,000 extinctions occur every year. But if the upper estimate of species

What is the sixth mass extinction and what can we do about it?

https://www.worldwildlife.org/stories/what-is-the-sixth-mass-extinction-and-what-can-we-do-about-it
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. In this definition, it's important to note that, in geological time, a 'short' period can span thousands or even millions of years.

What Is Species Extinction? What Happens When A Species Goes Extinct?

https://www.scienceabc.com/nature/animals/what-is-species-extinction-and-what-do-we-lose-when-a-species-goes-extinct.html
Species extinction is the complete extermination or dying of a species. The loss of a species impacts food chains, food webs, and pollination services.

There have been five mass extinctions in Earth's history

https://ourworldindata.org/mass-extinctions
Magnitude is the percentage of species that are lost. Rate is how quickly this happens. These metrics are inevitably linked, but we need both to qualify as a mass extinction. In a mass extinction, at least 75% of species go extinct within a relatively (by geological standard) short period of time. 3 Typically less than two million years.
