Relict (biology)

In biology, a "relict" refers to a species, population, or ecosystem that has survived from an earlier geological or evolutionary period and has largely remained unchanged despite significant changes in the environment or the ecosystem surrounding it. Relicts are often remnants of a once more widespread group and may reflect ancient lineages that have persisted through time. Relict species can often be found in isolated areas, such as mountain ranges, islands, or specific habitats that have remained relatively undisturbed.
