In Pennsylvania caves were used by newcomers as homes for a long time, certainly half a century. They generally were formed by digging into the ground about four feet in depth on the banks or low cliffs near the river front. The walls were then built up of sods or earth laid on poles or brush; thus half only of the chamber was really under ground.
In ancient writing, apparently the best known of the African cave-dwellers were the inhabitants of the "Troglodyte country" (Ancient Greek: Τρωγλοδυτική) on the coast of the Red Sea, as far north as the Greek port of Berenice, of whom an account was preserved by Diodorus Siculus from Agatharchides of Cnidus, and by Artemidorus Ephesius in Strabo.
Many insect troglobites are Orthopteran, Collembolan, or Blattodean, for example, and given the nature of their open-air ancestral species, it would be in no way surprising that where a cave becomes available, it soon is invaded by opportunistic troglophiles that may be widely distributed and may evolve similarly in separate caves in different ...
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).

Subterranean fauna is found worldwide and includes representatives of many animal groups, mostly arthropods and other invertebrates.However, there is a number of vertebrates (such as cavefishes and cave salamanders), although they are less common.
The ancestors of today's American Indigenous peoples were the Paleo-Indians; they were hunter-gatherers who migrated into North America. The most popular theory asserts that migrants came to the Americas via Beringia , the land mass now covered by the ocean waters of the Bering Strait .

Troglomorphism is the morphological adaptation of an animal to living in the constant darkness of caves, characterised by features such as loss of pigment, reduced eyesight or blindness, and frequently with attenuated bodies or appendages.
