Essay

Consider that fossils of Homo erectus dating between 1.66 and 1.85 mya have been found scattered across Eastern Europe through China and Southeast Asia and dating back to 2.4 mya in Africa.The earliest known specimens of anatomically modern Homo sapiens in Africa date back to roughly 200,000 years ago and 40,000 to 60,000 years ago across Europe and Asia,with some at 115,000 years ago in India.Additionally,Homo neanderthalensis was present across Europe by 150,000 years ago and then spread into western Asia.If there were no evidence indicating the presence of any other early Homo species in Europe,propose a hypothesis that would be supported by this information.
