Evolution both a theory and a fact, Response to Leona's post
There is always confusion and debate about evolution framework. In science a theory is simply an explanation or model of the world that makes testable predictions. A scientific fact refers to experimental or empirical data or objective verifiable observation. However in general a fact refers to things that can be explained by strong evidence. For example, in daily conversation there are some theories that are conceived as facts.When we say the earth revolves around the sun and objects fall due to gravity, we use these statements as facts. Therefore, for the same reason that gravity can be called a fact and can be tested and observed and there is strong evidence for it , evolution can be called a fact as well. There are also some debates that evolution theory has not been proven. But, the proof is mistaken by urging evidence. As a matter of fact, proof of a theory is only possible through mathematics and logic and not through natural sciences. In scientific definition, evolution is an observable process that occurs whenever a population of organisms genetically changes over time. Thus, evolution is widely considered both a fact and a theory.
