Some people believe in it while others do not. Belief itself is irrelevant. The theory could be true or false regardless of how many people believe or disbelieve.
I personally accept it as accurate due to the evidence that the fossil record and DNA gives us but many Christians (and those of other religious beliefs) believe that to say that Evolution is real is to deny that God created everything. There are those who believe that God created evolution. Evolution is a theory but in science terms a theory is a widely accepted (by scientists) explanation supported by data.
The evidence evolution occurs runs rampant through the genetic code of modern species and through the fossil record. Compare the earliest amphibians to sarcopterygian lungfish. Considered legged cetaceans. Examine the human chromosome that is a fused pair of "monkey: chromosomes. Contemplate the GULO gene. Why should we share a defective gene for the synthesis of ascorbic acid with old world monkeys?
These are all strong indicators evolution has occurred, though the theory of evolution is the explanation that ties these facts into a coherent picture.
The theory that evolution occurs during short periods of rapid change is punctuated equilibrium. This theory suggests that most species remain relatively unchanged for long periods, with bursts of significant change happening over short periods of time. This contrasts with the gradualism theory, which proposes that evolution occurs at a slow and constant rate.
The theory of evolution is the overarching scientific framework that explains how biological evolution occurs. Biological evolution refers specifically to the change in inherited characteristics of populations over generations. Biological evolution is the observed process that supports the theory of evolution.
Charles Darwin is known for the theory of evolution through natural selection. He proposed that all species of life have descended over time from common ancestors, and that the process of natural selection is the mechanism through which this evolution occurs.

Gradualism is the concept but I would not give it the ranking of scientific theory. It is more a subset of the theory of evolution by natural selection and was first formulated into that theory by Darwin.

The theory of rapid evolution rather than over a very long time.
Darwin's classic theory of evolution assumed that evolution is a slow, contunuous process, by which new species evolve and emerge. This is referred to at times as "organic evolution" and the "synthetic theory of evolution", or just the Darwinian theory of evolution. A newer theory, proposed originally by Niles Eldridge and Stephen Jay Gould is known as "punctuated equilibria", a model in which the evloution of new species occurs only periodically, in relatively rapid spurts. See "Time Frames the Rethinking of Darwinian Evolution and the Theory of Punctuated Equilibraia, Simon & Schuster, 1985"AnswerThe slow, constant process has also been called "gradualism."

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.
That theory is called punctuated equilibrium.
Answer 1A theory. Just as E=Mc2 is the theory of relativity.Answer 2Evolution is both a fact and a theory, although the fact and the theory of evolution are - at least in my book - two different things:The fact of evolution is the observation that lifeforms evolve over time.The theory of evolution is the model that explains how they evolve, and how that applies to our findings in genetics and palaeontology. The theory of evolution incorporates a number of well-tested hypotheses, laws, and facts.
Theory of evolution refers to animals and plants evolution along the time. Language evolution is another issue, not entirely related to the theory of evolution. It follows the theory of evolution on some way but it is related to culture evolution, not to the physical attributes evolution.
"Theory" means something much different in the world of science than it does in everyday use. Evolution is an observed fact. The theory around it is just our current understanding of the specific mechanics of it.
