Based on this analysis, it is believed that human language emerged in a single step. Before this rapid emergence, the L component, "roots", existed individually, lacked grammatical features, and were not combined with each other. However, once this was combined with the E component, it led to the emergence of human language, with all the necessary characteristics. Hierarchical structures of syntax are already present within words because of the integration of these two layers. This pattern is continued when words are combined with each other to make phrases, as well as when phrases are combined into sentences. Therefore, the Integration Hypothesis posits that once these two systems were integrated, human language appeared fully formed, and did not require additional stages.
