Theories are crucial to science because they provide a coherent framework for making sense out of scientific observations.
An example of such a theory is the Theory of Evolution. Without the theoretical framework of evolution, biologists would be limited to observing living things and noting the similarities and differences between them.
Basic biochemistry combined with cutting-edge molecular research leads us to a powerful explanation of a large set of biological observations. These observations only make sense using the REAL science of evolution. .
