Hominin sites are archaeological sites where evidence of past human ancestors, such as Homo sapiens, Homo neanderthalensis, Homo habilis, and other related species, have been found. These sites often contain fossils, tools, and other artifacts that provide valuable information about the behavior, evolution, and migration patterns of early humans. Studying hominin sites helps researchers understand how our ancestors lived, adapted to different environments, and interacted with other species. These sites are crucial for piecing together the puzzle of human evolution and building our knowledge of our shared history.
