Because although there is evidence to support the claims, it isn't possible to prove evolution indefinately.
Evolution is a process, theories of evolution are theories which explain that process
Simply; none.
There are several different theories of evolution. The most successful is by Charles Darwin through natural selection.
There is only one central "theory of evolution", which is the theory of evolution by natural selection that Charles Darwin pioneered. There have been different theories in the past - such as Jean-baptise Lamarck's theory of acquired traits - but these lost their status of scientific theory when they were shown to be wrong.
There are several theories to explain evolution, though evolution itself is not a theory. Perhaps the best known is Darwin's theory through natural selection.
Scientists test ideas about chemical evolution by using computer models.
Evolution is a process, theories of evolution are theories which explain that process
No, there are no other theories but the theory of evolution by natural selection that explain so much about evolution.
Simply; none.
Natural selection, I'm not sure, and Consumer-based evolution, respectively.
by making theories

In a phrase; the mechanism of natural selection.
Darwin's Theory of Natural Selection: The process by which favorable traits become more common in a population over successive generations. Lamarck's Theory of Inheritance of Acquired Characteristics: Organisms acquire traits during their lifetime and pass them on to their offspring. Genetic Drift: Changes in allele frequencies in a population due to random events. Mutation: Changes in the DNA sequence that can lead to genetic variation. Gene Flow: Movement of genes between populations through migration, influencing genetic diversity.
There is no evidence to suggest that Charles Darwin renounced his theory of evolution before his death. In fact, he continued to write in support of evolutionary ideas and even published a book called "The Descent of Man" in 1871. Darwin's theory of evolution remains one of the most influential and widely accepted scientific theories to this day.
Unanswerable.
He came up with the most widely accepted mechanism for evolution, known as natural selection.
