    Gould said he did not know him and had no information about him.

    Ok DBT9, what about one Gould does acknowledge.
    Gould extols Theodosius Dobzhansky as “the greatest evolutionist of our century.” Gould cites as “direct evidence” for evolution the small-scale changes within species of moths, fruit flies, and bacteria.
    Concerning the fruit flies of Gould’s argument, Dobzhansky says mutations “usually show deterioration, breakdown, or disappearance of some organs. . . . Many mutations are, in fact, lethal to their possessors. Mutants which equal the normal fly in vigor are a minority, and mutants that would make a major improvement of the normal organization in the normal environments are unknown.”
    Such variations within species are irrelevant to evolution. Evolution’s problem is to change one species into another species.
    Science, the official magazine for the American Association for the Advancement of Science, also spiked Gould’s argument: “Species do indeed have a capacity to undergo minor modifications in the physical and other characteristics, but this is limited and with a longer perspective it is reflected in an oscillation about a mean [a position about midway between extremes].” In both plants and animals, variations within a species will oscillate or move about like pellets shaken in a glass jar—the variations are held within the boundaries of the species just as the pellets are confined within the jar. Just as the Bible’s account of creation says, a plant or an animal may vary, yet it is restricted to reproduce “according to its kind.”—Genesis 1:12, 21, 24, 25.
