The hominoids are descendants of a common ancestor.. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [1]

Recent human evolution refers to evolutionary adaptation, sexual and natural selection, and genetic drift within Homo sapiens populations, since their separation and dispersal in the Middle Paleolithic about 50,000 years ago. Contrary to popular belief, not only are humans still evolving, their evolution since the dawn of agriculture is faster ...
Homo heidelbergensis (also H. erectus heidelbergensis, [1] H. sapiens heidelbergensis [2]) is an extinct species or subspecies of archaic human which existed from around 600,000 to 300,000 years ago, during the Middle Pleistocene.
Human remains that had been decomposing “for an extended period of time” have been discovered just off of a public hiking trail in Utah, police said. The Washington City Police Department ...
The step-by-step control of its embryogenesis was visualized by attaching fluorescent dyes of different colours to specific types of protein made by genes expressed in the embryo. [9] A dye such as green fluorescent protein , originally from a jellyfish , was typically attached to an antibody specific to a fruit fly protein, forming a precise ...
refused to turn over to investigators a video he had taken of a protest in San Francisco.
