Because there's supporting evidence for it. Lots of supporting evidence. Overwhelming, awe-inspiring amounts of supporting evidence.

A scientific theory is not just a guess. My chemistry teacher explained it this way: a theory is something we can explain (the theory of evolution or the theory of relativity). A law is something we can't explain (the law of gravity. We know it works, we're just not sure exactly why or how).

Charles Darwin spent years developing his hypothesis of natural selection. There is ample evidence supporting his final theory, some found long after his death. To this day, archeologists still find fossil evidence that fits into Darwin's explanation of changing species.

Why is Darwins theory more than just a guess?

Darwin's theory of evolution by natural selection is supported by a vast amount of evidence from various scientific fields, including genetics, paleontology, and biogeography. It has been tested and confirmed through numerous observations and experiments, making it a well-established scientific theory rather than just a guess.


Evolution is a guess or a serious theory?

Evolution itself is a fact, as it can be observered in both the environment and in the laboratory. A theory is a statement or series of statements which describes and explains a natural phenomenon based upon a solid foundation of evidence. The theory of evolution fits into the criteria of a theory.


What does it mean when it states that evolution is just a theory?

Evolution is a fact. The theory of evolution by natural selection is what you are trying to talk about. When someone says " evolution is just a theory " they are using the vulgar, common sense of the word theory. They mean guess, hunch and the like. The theory of evolution by natural selection is in the scientific sense of the word theory, which means a body of explanatory work supported by myriad lines of converging evidence that has been tested rigouusly and replicated often. Any good dictionary uses this scientific meaning of theory as the primary meaning of the word.


Why is evolution considerd a theory?

Evolution, the change in allele frequency over time in a population of organisms, is a fact. The theory of evolution by natural selection explains much of this fact. That is what a theory is. A consistent explanation of a phenomenon, or a series of phenomenon, that is supported by massive amounts of evidence, containing both facts and laws and is able to make predictions that generate testable hypothesis. A theory, in the scientific sense, is not a guess.


Why is evolution theory not fact?

Evolution is a scientific theory that is supported by overwhelming evidence from various fields such as paleontology, genetics, and microbiology. The term "theory" in science does not mean a guess, but rather a well-substantiated explanation based on evidence. While evolution is widely accepted among scientists, it is not considered a fact in the same way as established scientific laws because theories are subject to modification based on new evidence.

Why is evolution reffered to as a theory?

I don't exactly know why evolutionists refer to it as a theory, but I do know this. A theory is an explanation or model based on observation, experimentation, and reasoning. According to the definition of a theory, evolution is not a theory. Evolution cannot be based on observation. No one was here to observe it. So evolution should be classified as a hypothesis not a theory. It is only a guess as to how things came about.

What is the difference between a hypothesis and a theory such as the Theory of Gravitation or the Theory of Evolution?

a hypothesis can also be called an educated GUESS. while a theory can be considered as a group of guesses with particular proper research


Why do people preach evolution when it is just a theory?

Because non-scientists do not understand what a scientific theory actually means. It is not a random guess. Scientific theories are formed based on evidence and experimentation.The scientific community advocates evolution because all the evidence of life on our planet supports the theory.

How does theory differ from a guess?

a theory is backed up by facts while a guess isnt.


Is a theory or a hypothesis?

Evolution is an observed and observable fact. The theory of evolution by natural selection explains many things about evolution. The theory generates testable hypothesis, as any good theory does. Remember, theory is the highest concept in science.


How is a theory different from a hypothesis?

A hypothesis is a guess in what you think it is a theory is a fact and someone already proved it in the past.


Why is evolution a theroy?

Evolution is a scientific theory because it provides a well-supported explanation for the diversity of life on Earth based on observable evidence from fields like biology, genetics, geology, and paleontology. The theory of evolution has been tested and confirmed through numerous scientific studies and continues to be refined as new evidence emerges. In scientific terms, a theory is an explanation that has been rigorously tested and supported by multiple lines of evidence, not just a guess or hypothesis.
