The precise origins of Homo Sapiens the species to which all human beings belong are subject to speculation based on increasing number of fossils,on genetic and anatomical studies and on interpretation of geological records.Most scientists believe that humans evolve from apes like primate ancestors in a process started millions of years ago.
Recent theories trace the first homonid to Africa where at least homonids appeared to 5 to 7 million years before. The first line was Australopithecus a social animal that lived from 5 million to 3 million years.The second human line was Homo Hobilis a large brained homonid which walked straight.They appeared some 2.5 million years lived in semi permanent camps had food gathering economy.
Home Erectus the nearest ancestor to humans appeared in Africa 2 million years and began to spread in Asia and Europe.Its skeletal system was similar to that of modern humans.They hunted,learned to control fire and may had some primitive language skills.
Brain development of Homo Sapiens occurred between 500,000 and 50,000 in Africa.Evidence of homonids in Siberia dates as early as 300,000.
