Black Skull
KNM-WT 17000 (also known as "The Black Skull") is a fossilized adult skull of the species ''Paranthropus aethiopicus''. It was discovered in West Turkana, Kenya by Alan Walker in 1985. Estimated to be 2.5 million years old, it is an adult with an estimated cranial capacity of 410 cc. Its characteristics include a robust build with a prominent sagittal crest. Its coloration is due to the high manganese content of the material it was embedded in. This fossilized cranium's face projects far outward from the forehead, has wide flared zygomatic arches, and has the largest sagittal crest of any early human. The molar and premolar roots in the jaw are indicative of this early human having massive cheek teeth; an adaptation for heavy chewing. It is the only known adult skull of the species. While its relationship to other fossil hominin taxa was not immediately clear at the time of its discovery, further studies have suggested it is a possible ancestor of two species: ''Paranthropus b ...

The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...
