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 March of Progress, [1] [2] [3] originally titled The Road to Homo Sapiens, is an illustration that presents 25 million years of human evolution. It was created for the Early Man volume of the Life Nature Library , published in 1965, and drawn by the artist Rudolph Zallinger .

{{Human evolution | state = expanded}} will show the template expanded, i.e. fully visible. {{Human evolution | state = autocollapse}} will show the template autocollapsed, i.e. if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar, but if not, it is ...
To provide an accessible overview, historians divide human history into different periods organized around key themes, events, or developments that have shaped human societies over time. The number of periods and their time frames depend on the chosen topics, and the transitions between periods are often more fluid than static periodization ...
Biological anthropology, also known as physical anthropology, is a natural science discipline concerned with the biological and behavioral aspects of human beings, their extinct hominin ancestors, and related non-human primates, particularly from an evolutionary perspective. [1]
