Thinkquote of the day: New species seldom or never observed

A key problem with the argument over Darwinian evolution (evolution by natural selection acting on random mutations) is that so few actual examples of speciation (new species forming) have ever been observed that we really have no way of knowing for sure whether Darwin had the right idea. That is precisely why acceptance of Darwinism is so often treated as some kind of loyalty test for science; in reality, the Darwinist is taking a great deal on faith.

As Jonathan Wells noted in his controversial Politically Incorrect Guide to Darwinism and Intelligent Design,

So except for polyploidy in plants, which is not what Darwin's theory needs, there are no observed instances of the origin of species. As evolutionary biologists Lynn Margulis and Dorion Sagan wrote in 2002: "Speciation, whether in the remote Galapagos, in the laboratory cages of the drosophilosophers, or in the crowded sediments of the paleontologists, still has never been directly traced." Evolution's smoking gun is still missing.

- Jonathan Wells, Politically Incorrect Guide to Darwinism and Intelligent Design , p. 55, quoting Lynn Margulis and Dorion Sagan, Acquiring Genomes: A Theory of the Origin of Species (New York: Basic Books, p. 32)

(Note: Polyploidy is gene-swapping by the doubling of chromosomes, from which new species of plants can arise. (But it's no particular help to Darwin's theory because sexual reproduction is not involved.) Drosophilosophers is a humorous coinage for researchers who study fruit flies (drosophilus spp.).)
