Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. One of the earliest defining human traits, bipedalism -- the ability to walk on two legs -- evolved over 4 million years ago.
Other scientists have argued that human beings originated in Africa before moving to other regions 150,000 to 200,000 years ago. Homo sapiens discovered in Middle Awash, Ethiopia, from 160,000 years ago were believed to be the oldest 'modern' human beings. Other remains previously found in Israeli caves are thought to have been more recent and 80,000 to 100,000 years old.
