It was accepted after evidences were proved non-testable.

It was accepted after scientists proved that its results are non-observable.

Answer;

It is based on evidence obtained after several investigations.

Explanation; A scientific theory is an explanation that is supported by a large amount of evidence. Evidences are results collected when a theory or hypothesis is being tested. Scientific evidence serves to either support or counter a scientific theory or hypothesis. The theory of evolution just like any other theory must have been testable and its results observable for it to be considered viable. Therefore; the theory of evolution was validated after scientists completed several investigations to gather evidence. It was proposed after current evidences were investigated several times.

After many different investigations, scientists obtained several shreds of evidence to support this theory.

Explanation:

It is supported by evidence from different scientific branches, such as genetics, geology, paleontology and developmental biology. Darwin's theory of evolution is the most accepted and substantiated theory in biological sciences. Darwin had no clue about genetics but his theory was purely based on evolutionary characters or traits.
