The statement that best describes the process of how later Paleo-Indian cultures replaced earlier ones is "over time, groups adapted to changing conditions and developed new tools and habits."
Scientists identify the first inhabitants of the Americas at the end of the Pleistocene Period, as Paleo-Indian. This means that from the search of historians, Paleoindians were the first people in the Western Hemisphere. They probably were the people who crossed the Berin Strait coming from Asia.
