It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code.
Circumstantial evidence is evidence.
People in general have no notion of the sort and amount of evidence often needed to prove the simplest matter of fact.
There is no direct evidence that [Alex] Haley sat down with the F.B.I.
The scientific method actually correctly uses the most direct evidence as the most reliable, because that's the way you are least likely to get led astray into dead ends and to misunderstand your data.

As has repeatedly been stated, the underlying hypothesis, which in a number of cases has been supported by direct experimental evidence, is that each gene controls the production, function, and specificity of a particular enzyme.
But yet, I say, if imputation and strong circumstances, which lead directly to the door of truth, will give you satisfaction, you may have it.
I would rather not depend on sophisticated statistics to demonstrate behavior. I prefer to design experiments that will produce interocular effects—hit you between the eyes.

With my research, I really need absolute confirmation of what actually happened, direct physical connections to the past.
A second type of direct evidence is formed by statements, whether as formal legends or personal information, regarding the age or relative sequence of events in tribal history made by the natives themselves.
The amount of knowledge which we can justify from evidence directly available to us can never be large. The overwhelming proportion of our factual beliefs continue therefore to be held at second hand through trusting others, and in the great majority of cases our trust is placed in the authority of comparatively few people of widely acknowledged standing.
