The Mind's Big Bang HUMAN EVOLUTION - Documentaries

Human evolution is the transformative process leading up to the look of anatomically modern people. The subject often covers the evolutionary record of primates, in specific the genus Homo, and the emergence of Homo sapiens as an unique species of hominids (or "primates") instead of studying the evolutionary history that led to primates. The study of human evolution involves several scientific self-controls, including physical sociology, primatology, archaeology, paleontology, ethology, grammars, evolutionary psychology, embryology and genetic makeups.
Either Sahelanthropus or Orrorin might be the last shared forefather between people and chimps. The early bipedals at some point evolved into the australopithecines, and later into the genus Homo.
The earliest documented members of the genus Homo are Homo habilis, which evolved around 2.3 million years ago; the earliest species for which there is positive evidence of use of stone tools. The brains of these early hominins were concerning the exact same dimension as that of a chimpanzee, although it has actually been suggested that this was the time where the human SRGAP2 gene doubled, producing a much more rapid circuitry of the frontal cortex. During the next million years a process of encephalization began, and with the arrival of Homo erectus in the fossil record, cranial capability had doubled to 850 cm3. This rise in human mind size is comparable to every generation having an extra 125,000 nerve cells much more than their parents.
