Paranormal events are phenomena described in popular culture, folk, and other non-scientific bodies of knowledge, whose existence within these contexts is described to lie beyond normal experience or scientific explanation.

Modern humans (Homo sapiens, ssp. Homo sapiens sapiens) are the only extant members of the subtribe Hominina, a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; and a general trend toward larger, more complex brains and societies.
Early hominins—particularly the australopithecines, whose brains and anatomy are in many ways more similar to ancestral non-human apes—are less often referred to as "human" than hominins of the genus Homo. Several of these...

Disciplines which use science like engineering and medicine may also be considered to...

At the time, it was known as the Year of the Consulship of Honorius and Aristaenetus (or, less frequently, year 1157 Ab urbe condita).
