Color depth triangle does enclose a much larger gamut, so whether more than three primaries results in a difference to the human eye is not yet proven, since humans are primarily trichromats, though tetrachromats exist. Color depth Color depth or colour depth (see spelling differences), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video framebuffer, or the number of bits used for each color component of a single pixel. For consumer video standards, such as High Efficiency Video Coding (H.265), the bit depth specifies the
Muscular evolution in humans life. This is not, however, the case for current hunter gatherer and foraging populations, such as the Andaman Islanders, who retain overall robusticity. In general, though, hunter gatherers tend to be robust in the legs and farmers tend to be robust in the arms, representing different physical load (i.e., walking many miles a day versus grinding wheat). Muscular evolution in humans Muscular evolution in humans is an overview of the muscular adaptations made by humans from their early ancestors to the modern man. Humans are believed to be predisposed to develop muscle density as early humans depended on muscle structures
