Human Early Stages of Development From Hominids to Homo Sapiens

National Geographic world history textbook states; Although modern science has given more precise methods for examing the prehistory of humankind than we have ever had before,much of our understanding of early humans still depends on guesswork. (in prehistory people live  and die without record made of their lives). The rate of new discoveries of the current theory of early human life might be changed in a few years. Tim Aldred said we only have history as real source to enlighten us about the early human ancestors, because none of them live to see our day. Our observation of history must be done  with intellectual skills and sound judgment. History says that we came from Hominids to Homo Sapiens. The earliest humanlike creatures lived in Africa; as long as three to four millions  years ago (who denies that?)  Called Australopithecines, or otherwise called "southern apes."The discoverer is Donald Johanson, his research shows they flourished in eastern  and southern Africa. The were the first hominids (humans and other creatures that walk upright) to make simple stone stools.
