theory
A well-tested explanation that unifies a broad range of observations and hypotheses is known as a scientific theory. For example, the theory of evolution by natural selection explains the diversity of life on Earth by integrating evidence from genetics, fossil records, and comparative anatomy. It not only accounts for a wide variety of biological phenomena but also generates testable predictions, making it a foundational concept in biology.
a theory
Scientific theories often emerge from extensive observation, experimentation, and the formulation of hypotheses that withstand rigorous testing. Over time, as evidence accumulates and predictions are validated, these hypotheses may evolve into widely accepted theories. This process involves peer review, replication of results, and refinement of ideas, leading to a deeper understanding of natural phenomena. Ultimately, a scientific theory is a comprehensive explanation that unifies various observations and experimental results.
