Only someone grossly ignorant of the actual fossil record could say something this amazingly false with a straight face:

Moreover, laboratory experiments reveal how close to impossible it is for one species to evolve into another,
Gee, really? Let's see the citations to those "laboratory experiments", shall we? I just won't hold my breath, the IDers never provide any when asked, because they're just making this stuff up as they go along. When they say, "laboratory experiments reveal", it really means, "as an uninformed anti-evolutionist, I'm posting my presumption that some experiment must support my empty presumptions, because I've never actually read any that I can cite if asked."
Meanwhile, here are some *real* citations on speciation -- including dozens of OBSERVED cases of actual speciation:

Abstract:
Analysis of contact between two chromosomal races of house mice in northern Italy show that natural selection will produce alleles that bar interracial matings if the resulting offspring are unfit hybrids. This is an important exception to the general rule that intermixing races will not tend to become separate species because the constant sharing of genes minimizes the genetic diversity requisite for speciation.

Abstract:
The climatic and geographic history of the Pleistocene and Holocene periods modified the distribution of the bird population in the South American forests. Forest birds are found dispersed in the Yungas and Paranese areas with only minimal infiltration of the Chaco woodland, indicating an atmospheric change during the interglacial periods. In the Chaco lowlands, the interactions between non-forest birds reveal the existence of presence of a forest belt along the Bermejo and Pilcomayo rivers.

Abstract:
J.A. Coyne wrongly asserted that neodarwinism includes allopatric evolution but not sympatric evolution. Allopatric evolution occurs among geographically isolated populations, whereas sympatric evolution occurs within one species' entire population. Both are neodarwinian since each results from natural selection of genetic variation. Also, Coyne failed to recognize that the molecular models used to illustrate how genetic changes bring on speciation are most useful when researchers acknowledge that both inherited epigenetic and genetic changes affect speciation.

From talk.origins
A talk.origins participant writes:
1) Speciation occured in a strain of Drosophila paulistorum sometime between 1958 and 1963 in Theodosius Dobzhansky's lab. He wrote this up in:
Dobzhansky, T. 1973. Species of Drosophila: New Excitement in an Old Field. Science 177:664-6692) A naturally occurring speciation of a plant species, Stephanomeria malheurensis, was observed in Burns County, Oregon. The citing is:
Gottlieb, L. D. 1973. Genetic differentiation, sympatric speciation, and the origin of a diploid species of Stephanomeria. American Journal of Botany 60(6):545-5533) In the 1940's a fertile species was produced through chromosome doubling (allopolyploidy) in a hybrid of two primrose species. The new species was Primula kewensis. The story is recounted in:
Stebbins, G. L. 1950. Variation and Evolution in Plants. Columbia University Press. New York4) Finally, two workers produced reproductive isolation between two strains of fruit flies in a lab setting within 25 generations. I don't have the paper handy, so I can't give the species. The partial citing of the paper is:
Rice and Salt 1988. American Naturalist 131:911-Dobzhansky got a subpopulation of D. paulistorum to speciate in his lab. The reference is:

You should pray to the Lord to give you the insight to realize that God created evolution, not Darwin.
Opinion is not evidence, and all you ever post is highly subjective opinion, and out and out falsehood. Stephen Gould's admission that the evidence didn't exist is all we need to judge the credibility of the tripe you constantly post to disrupt these threads.
You're spamming.
You are just another liberal troll trying to use up FR bandwidth, please go back to DU.
Evolutionists are finally (and with great reluctance) publicly acknowledging large morphological gaps in the fossil record. These gaps are so distinct that evolutionists now recognize them as real, rather than as an artifact of poor fossil preservation.
The known fossil record is not, and never has been, in accord with gradualism. The majority of paleotologists felt their evidence contradicted Darwin's stress on minute, slow and cumulative changes leading to species formation STANLEY
One must acknowledge that there are many gaps in the fossil record...there is no reason to think that all or most of these gaps will be bridged RUSE
The absence of fossil evidence for intermediary stages between jamor transitions in organic design..is a persistent and nagging problem for gradulastic accounts of evolution...GOULD
The fossil record flatly fails to substantiate the expectation of finely graded change Eldredge and Tattersall
Undeniably, the fossil record has provided disappointingly few gradual series. Origins of many groups are still not documented...Futuyma
So many more evolutionists recognizing what YOU fail to acknowledge
I can't understand why supposedly religious men lie
like they do just for substantiation of their own faith.
I suppose clay feet can show up in the best of men
nowadays.
