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.
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 theory of behavioural archaeology outlines four strategies in which human behaviour and material culture can be examined in order to answer questions associated with archaeological inquiry. [1] Behavioural archaeology also defines archaeology as a discipline that transcends time and space as it is the study of not only the past, but also of ...
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 ...
Experts estimate that modern humans first appeared between 42,653 and 42,269 years ago. Therefore, the authors conclude this suggests the two species of humans co-existed in these regions for ...
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.
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
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 ...
