Natural selection is a process that leads to the adaptation of a species to its environment, not its extinction.

The Permian-Triassic extinction event is considered the most severe extinction event in Earth's history, with an estimated 96% of all marine species and 70% of all terrestrial vertebrate species becoming extinct.

Extinction leads to a decrease in biodiversity, disruption of ecosystem services, and loss of genetic diversity, not an increase in resilience to environmental change.

The background extinction rate is the average rate of extinction that has occurred over a long period of time, typically millions of years.

The passenger pigeon, dodo, and Steller's sea cow are all examples of species that went extinct due to habitat loss.

The extinction of a keystone species can have a cascading effect on an ecosystem, leading to population declines in other species, changes in ecosystem structure and function, and loss of biodiversity.

Captive breeding programs, habitat restoration, and reintroduction programs are all examples of conservation measures that have been successful in preventing extinction.

The IUCN Red List is a global database of threatened and endangered species.

Endemic extinction is not a type of extinction. It refers to the extinction of a species that is restricted to a particular geographic area.

The term 'sixth extinction' refers to the current extinction event that is occurring due to human activities, such as habitat loss, climate change, and overexploitation.

The blue whale, giant panda, and African elephant are all examples of species that have been threatened with extinction due to overexploitation.

The Convention on Biological Diversity (CBD) is an international treaty that aims to conserve biodiversity, promote sustainable use of biodiversity, and share the benefits of biodiversity fairly and equitably.

A high reproductive rate can help a species recover from population declines, making it less vulnerable to extinction.

Conservation status refers to the risk of extinction of a species, as determined by factors such as population size, geographic range, and threats to the species.

The California condor, black-footed ferret, and giant panda are all examples of species that have been successfully reintroduced to their former range.
