Indeed. I know no modern working scientist who would make such an assumption.
Well I'm no scientist, so let me ask you...
Would it be fair to say that such assumptions are not scientific?
And would it be fair to say that, in the absence of evidence or observation, claims of specific loose ends being tied up are also not scientific?
Would you say that an unqualified claim that evolutionary speciation arises from random mutagenic causes is unscientific?
