You've got Steve Gould and others with unassailable credentials claiming that mutations cannot produce new species:

"A mutation doesn't produce major new raw (DNA) material. You don't make a new species by mutating the species."

    Stephen Jay Gould,  Prof of Geology and
    Paleontology, Harvard University
    "Is a New and General Theory of Evol. Emerging?
    Lecture at Hobart&Wm Smith College,Feb4,1980

No I don't. I have your uncited source, creationist Luther Sunderland, a man with a rich record of misquoting evolutionists, or presenting snippets of their views so widely out of context that their meaning is inverted fully 180 degrees, saying that Gould said that.

Even if it were an accurate quote (it reads like a paraphrase of some sort) it's too short and isolated a snippet to determine either the actual point Gould intended to make, or the body of data upon which his point was based. Naturally, neither issue is of interest to creationists.

Gould's 1980 paper is available on the web but you'd have to pay for it and I don't feel any such need personally. There are however other quotes to the same effect from other scholars and the point appears obvious enough given the generally destructive nature of mutations:

"With ... the inability of mutations of any type to produce new genetic information, the maintenance of the basic plan is to be expected." (p.168) "There are limits to biological change and ... these limits are set by the structure and function of the genetic machinery." (p. 153)

"No matter how numerous they may be, mutations do not produce any kind of (E)volution."

"A random change in the highly integrated system of chemical processes which constitute life is certain to impair - just as a random interchange of connections in a television set is not likely to improve the picture."
