Within climatic geomorphology one approach is to study relict landforms to infer ancient climates. There are nine Ponto-Caspian and five boreal relict species. Consequently, the Barbary macaque is now restricted to small, fragmented relict habitats. Many of the species are relict and endemic. Lake Sommen stands out for having as much as three glacial relict crustcean species. The new varieties were notably distinct from the surviving relict dialects. Hunting and habitat restriction have reduced the present-day species to fragmented relict populations. These primary heirs consist of the spouse relict, both parents, the son and the daughter. There are 218 endemic, 176 relict and rare 294 species. A remnant of the last of this relict herd had been saved in 1876. As a phylogenetic relict, it is the only known surviving member of its order. Today emmer is primarily a relict crop in mountainous areas. Scientists hypothesize that this is an evolutionary relict of diurnal animals like humans. Relict populations can be found in the Atlas Mountains of Africa. The genus "Gymnogyps" is an example of a relict distribution.
