Cave of Forgotten Dreams (Cauvet)

The Chauvet-Pont-d'Arc Cave in the Ardèche department of southern France is a cave that contains some of the earliest known cave paintings, as well as other evidence of Upper Paleolithic life.[1] It is located near the commune of Vallon-Pont-d'Arc on a limestone cliff above the former bed of the Ardèche River, in the Gorges de l'Ardèche. Discovered on December 18, 1994, it is considered one of the most significant prehistoric art sites. The cave was first explored by a group of three speleologists: Eliette Brunel-Deschamps, Christian Hillaire, and Jean-Marie Chauvet for whom it was named. Chauvet (1996) has a detailed account of the discovery. In addition to the paintings and other human evidence, they also discovered fossilized remains, prints, and markings from a variety of animals, some of which are now extinct. Further study by French archaeologist Jean Clottes has revealed much about the site. The dates have been a matter of dispute but a study published in 2012 supports placing the art in the Aurignacian period, approximately 30,000–32,000 BP.

Umwelt

In the semiotic theories of Jakob von Uexküll and Thomas A. Sebeok, umwelt (plural: umwelten; from the German Umwelt meaning "environment" or "surroundings") is the "biological foundations that lie at the very epicenter of the study of both communication and signification in the human [and non-human] animal."[1] The term is usually translated as "self-centered world".[2] Uexküll theorised that organisms can have different umwelten, even though they share the same environment. Basically, it is the idea that an organism, like homosapiens, can only perceive a part of the world, reality, the part they are biologically designed to perceive. Take light, which exists as ultraviolet, infrared, x-ray, our eyes can only perceive less than one trillionth of the spectrum. There are whole realities we can't perceive.
