The most widely accepted view among current anthropologists is that Homo sapiens originated in the African savanna between 200,000 and 250,000 years ago, descending from Homo erectus, and colonized Eurasia and Oceania by 40,000 years ago, and finally colonized the Americas by 10,000 years ago. They displaced Homo neanderthalensis, Homo floresiensis and other species descended from Homo erectus (which had colonized Eurasia as early as 2 million years ago) through more successful reproduction and competition for resources.
