What explanation that ties together many hypotheses and observations?

Answer 1

A unifying explanation that ties together various hypotheses and observations is often referred to as a "theory." For example, the theory of evolution by natural selection integrates numerous observations from genetics, Paleontology, and ecology, providing a cohesive framework to explain the diversity of life on Earth. This overarching theory not only accounts for disparate data but also generates new predictions and research directions, reinforcing its validity. By synthesizing multiple lines of evidence, such theories enhance our understanding of complex phenomena.
