They are internally consistent, supported by many lines of converging evidence, tested and passed tests innumerable time over many years, make testable prediction and are very good explanations for a broad class of phenomenon.
As scientific theories they have been around a long time and have been modified as new information was gather, but basically, they have stood the test of time very well.
People tend to say that scientific theories are "just" a theory because of a confusion between the common usage of "theory" and the scientific definition. (In everyday speech people often use the word "theory" in the sense of a "hunch" or "vague idea". This is not what the word means in a scientific context). A scientific theory is deduced from observations and is the simplest way of describing natural phenomena. It is testable, observable, predictable, and falsifiable. Scientific theories are not the same thing as hypotheses, which are explanations that haven't been demonstrated or verified. A scientific theory has evidence to back it up. The common usage of 'theory' suggests an explanation that someone hasn't proven, or isn't able to prove. It doesn't imply evidence that has been tested; it doesn't imply predictability. When someone hears, for example, "Big Bang theory" or "the theory of evolution", they may hear the word 'theory' and associate those scientific theories with someone's opinion or suggestion. In reality, these theories are the best scientific explanations for a myriad of phenomena across multiple scientific definitions. In science, "just a theory" is a very good place to be.
In science, a theory is something that is not fully proven, but has strong supporting evidence. Some common theories that are well known, and seen by most people as fact include; Evolution, Plate Tectonics, and Gravity. All three of these have enough evidence to be scientifically sound, but we have not yet given 100% proof to turn them from scientific theory into scientific law.
All are testable and falsifiable, and all have evidence to back them up. Without evidence, it is a hypothesis.

Some common communication theories are interpersonal communication, group communication and mass communication. There are many more theories but these three are the most common.
The three main theories of evolution are Lamarckism, Darwinism, and punctuated equilibrium. Lamarckism suggests that organisms can pass on acquired traits to their offspring, while Darwinism proposes natural selection as the main mechanism of evolution. Punctuated equilibrium suggests that evolution occurs in rapid bursts separated by long periods of stability.
No. But according to the best theories of evolution we share a common ancestor.
Evolution.
There is currently only one theory of evolution: the theory of evolution by natural selection, as pioneered by Charles Darwin, which describes how the diverse modern life forms derived from their common ancestors.
adaptation or evolution are the two most common.

The missing link refers to a perceived gap in human evolution. Human evolution theories believe that human beings evolved from the common ape over many centuries of time.

Some common theories associated with disabilities include the medical model, which focuses on individual impairments and medical interventions; the social model, which views disability as a result of societal barriers and discrimination; and the biopsychosocial model, which considers biological, psychological, and social factors in understanding disabilities. These theories offer different perspectives on how disability is perceived and experienced in society.
The theory of evolution is no longer debated in the scientific community, because there is no competing theory that satisfactorily explains, or is supported by, the mounting archaeological and genetic evidence. Put simply, evolution is the only scientific theory consistent with this evidence. To distinguish a scientific theory from a common theory, refer to the related question, What is the Scientific Theory?.Elements of the general population have challenged and debated the theory of evolution since Charles Darwin presented his book, On the Origin of the Species, in 1859, and many continue to do so.
