relict species

A relict species, also known as a paleoendemic species, is an ancient species that was once widespread but is now found only in a much smaller area. This phenomenon can be caused by habitat loss, pollution, climate change, or the introduction of new predators.1

Relict species are a type of endemic species, meaning their geographic range is confined to a single area. They are often found in isolated locations like islands or mountains and may have specialized adaptations for unique habitats, making them vulnerable to environmental changes and extinction. Sometimes, a relict species is the only surviving member of its genus.1
