Temporal light artefacts (TLAs) are undesired effects in the visual perception of a human observer induced by temporal light modulations. Two well-known examples of such unwanted effects are flicker and stroboscopic effect. Flicker is a directly visible light modulation at relatively low frequencies (< 80 Hz) and small intensity modulation levels.
The hypothesis also speculates that artifacts from past civilizations could be found on the Moon and Mars, where erosion and tectonic activity are less likely to erase evidence. The concept of pre-human civilizations has been explored in popular culture, including novels, television shows, short stories, and video games.
"Behavioural Archaeology" was first published by Michael B. Schiffer, J. Jefferson Reid, and William L. Rathje in 1975 in the American Anthropologist journal. [1] Leading up to the publication, archaeology as a discipline was expanding in its practice and theory due to the specialisation of various areas and new ideas that were being presented to the community.
Spencer embraced a teleological notion where evolution was seen as having an ultimate and definite goal. Spencerian theory incorporated a progressive, unilineal explanation of cultural evolution in which human societies were seen as progressing through a fixed set of stages, from “savagery” through “barbarism” to “civilization”.

The lower layers of the cave were later dated to 92,000 years ago, [28] and a series of hearths, several human bodies, flint artifacts (side scrapers, disc cores, and points [29]), animal bones (gazelle, horse, fallow deer, wild ox, and rhinoceros [29]), a collection of sea shells, lumps of red ochre, and an incised cortical flake were found. [28]
A researcher claims to have found evidence of humans in Chesapeake Bay over 22,000 years ago. The assertion is yet another recent announcement claiming to push the arrival of humans in North ...
Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence (such as petrified skeletal remains, bone fragments, footprints) and cultural ...
The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science , more specifically in the psychophysics of visual perception .
