Middle Pleistocene Homo behavior and culture at 140,000 to 120,000 years ago and interactions with Homo sapiens

Fossils of a Middle Pleistocene (MP) Homo within a well-defined archaeological context at the open-air site of Nesher Ramla, Israel, shed light on MP Homo culture and behavior. Radiometric ages, along with cultural and stratigraphic considerations, suggest that the fossils are 140,000 to 120,000 years old, chronologically overlapping with H. sapiens in western Asia. Lithic analysis reveals that MP Homo mastered stone-tool production technologies, previously known only among H. sapiens and Neanderthals. The Levallois knapping methods they used are indistinguishable from that of concurrent H. sapiens in western Asia. The most parsimonious explanation for such a close similarity is the cultural interactions between these two populations. These findings constitute evidence of contacts and interactions between H. sapiens and MP Homo.
