What are the Four types of endemic species?

The four types of endemic species are:

1. Paleoendemics: These are ancient species that were once widespread but are now restricted to a small area due to historical changes.
2. Neoendemics: These species have recently evolved and are typically found in a specific region, often as a result of adaptive radiation.
3. Relict Endemics: These species are remnants of a larger group that once existed in a broader area but are now confined to a limited region due to environmental changes.
4. Ecological Endemics: These species are adapted to specific ecological niches and are often found in unique habitats, making them highly specialized and localized.
