The Early-Entry Model, which purports to explain this phenomenon, has not converged on one theory, but rather encompasses a multiplicity of theories, the common denominator of which is the fact that they show Asiatic peoples arriving in North America earlier than 11,500 years ago. Unlike the Clovis-First Model, the Early-Entry Model proposes that the Americas may have been peopled by several waves of migration occurring over an extended period of time.
