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 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.
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 ...

Lomekwi is an archaeological site located on the west bank of Turkana Lake in Kenya.It is an important milestone in the history of human archaeology. An archaeological team from Stony Brook University in the United States discovered traces of Lomekwi by chance in July 2011, and made substantial progress four years after in-depth excavations.
In visual perception, flicker is a human-visible change in luminance of an illuminated surface or light source which can be due to fluctuations of the light source itself, or due to external causes such as due to rapid fluctuations in the voltage of the power supply (power-line flicker) or incompatibility with an external dimmer.
The lack of other evidence of human activity (e.g. human or animal remains, or non-tool artifacts). The deep antiquity of the site (the next oldest date for human artifacts in the Americas is 30,000 BP, and that date itself is controversial). The sheer number of possible tools, up to 60,000 by one account. [6]
Transcendence: How Humans Evolved Through Fire, Language, Beauty, and Time is a non-fiction book by Gaia Vince published in 2019. It describes how human evolution was shaped by genetic, environmental and cultural factors. It has been reviewed by several science publications, including Nature.
