1.rules and techniques: the body of rules, ideas, principles, and techniques that applies to a subject, especially when seen as distinct from actual practice
A theory is a unifying explanation for a broad range of observations and hypotheses. A theory is not necessarily a true or complete explanation and its veracity is subject to repeated testing.
theory in a scientific sense is an explanation to a phenomenon that is based on observations, experimentation, and reasoning.
in a general sense it is set of statements or principles devised to explain a group of facts or phenomena.
A theory is a unifying explanation for a broad range of observations and hypotheses.
A theory is a hypothisis that has been tested multiple times and has been supported each time.
A sentence using theory in its scientific sense would be " Many scientists have a theory about why global warming exists." Theories are based off experiments and facts.
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.
Yes, evolution is a theory. But it is not "just a theory" in the sense that you probably mean. In layman's terms, we might speak of a theory as simply an idea or an opinion, such as "Well, that's YOUR theory..." In science, it is something else entirely, and when something becomes scientific theory, it has been very well substantiated. It is more synonymous with the word "fact" in this usage, unlike the previous usage I used as an example. in fact, all scientific discoveries are considered theories. hell, the fact that our bodies are made up of cells that reproduce is still just a theory.
Olfaction.
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.
In the general, every day sense of the word a theory is a supposition, a hunch or a speculation. It is unproven.A Scientific Theory is completely different from an every day theory. A scientific theory summarizes a hypothesis that has been supported with repeated testing and with facts that can be observed and/or measured. With that support a hypothesis moves to the next step in the scientific method and becomes accepted as a valid explanation of a phenomenon. Facts are the framework for the scientific method and a Scientific Theory is supported by facts.
Yes a scientific theory has to make sense. If it did not, scientists would not have enough information to understand and continue to gather data on the theory.
n0n sense
scientific law is unlike a scientific theory in a sense that its the next step above a scientific theory.A scientific law is one that has been proven, a scientific theory has not been proven yet.

a scientific theory is a well tested explanation for a wide range of observations of experiments in other words is an idea that makes sense.
No, it is a theory (in the scientific sense). This means that it was proposed, tested rigorously and passing strongly, and no evidence to disprove it has yet been found.
To pit it in a more accurate form; the theory of evolution by natural selection. Not a belief, a theory in the scientific sense.
In the scientific sense of the word 'theory' (ie. testable explanatory model), there is just the one theory of evolution: evolutionary theory, which incorporates the central theses of common descent and natural selection.
In relation to what? In a general sense they are the rules that govern their usage in mathematics and also define their properties. Huurrrmmppfff. I think.
The reason for this is because this will help someone understand you theory.
