Misrepresenting the Galapagos Finches
According to the online critique of Explore Evolution by the National Center for Science Education: (A) EE claims that natural selection produced only oscillations in beak size in Galápagos finches, but “in the course of a few years, the size changes within species were large enough to explain the differences among the various species of Galápagos finches,” and “the size and shape of finch beaks did change over the course of the 30 years that biologists have been studying the populations.”  (B) EE claims that Galápagos finch species are merging rather than diversifying, but “the hybridization observed in the finches is not enough to merge two species, and observations in the field have actually shown substantial evidence of incipient Read More ›
Haeckel, Darwin, and Textbooks
According to the online critique of Explore Evolution by the National Center for Science Education (NCSE): (A) EE falsely claims that Darwin accepted Ernst Haeckel’s Biogenetic Law that “ontogeny recapitulates phylogeny.” In particular, the claim in EE that “Darwin thought that the observable similarities in different embryos revealed what the ancestors to these organisms would have looked like” [p. 66 of EE] “contradicts the majority view of prominent Darwin scholars (including Ernst Mayr, Stephen Jay Gould, David Hull, and Peter Bowler).”  (B) EE “falsely asserts Darwin thought the similarities between embryos were greater at the earliest stages of development,” and falsely suggests “that common descent and Haeckel’s Biogenetic Law require that the earliest stages of animal development are most Read More ›
Darwin’s Straw God Argument
Charles Darwin called The Origin of Species “one long argument.” The whole point of it was to show that living things are not special creations, but modified descendants of common ancestors. Although The Origin of Species listed many facts from nature, Darwin’s argument was basically theological, and it took this general form: The facts of nature are “inexplicable on the theory of creation,” but make sense on the theory of descent with modification. By “the theory of creation,” Darwin did not mean “creation within the past few thousand years.” Young-earth creationism was not the issue. The issue was whether a creator was necessary — after the origin of life itself — to explain the features we see in living things. Read More ›
Is the “Science” of Richard Dawkins Science Fiction?
Atheist Richard Dawkins is hopping mad at the makers of Expelled: No Intelligence Allowed. Dawkins accuses the filmmakers of “lying for Jesus” because they make it seem that he believes in intelligent design and space aliens. Dawkins is an outspoken critic of intelligent design (ID). In his 1986 book The Blind Watchmaker, Dawkins defined biology as “the study of complicated things that give the appearance of having been designed for a purpose.” Design is only an appearance, because (as the subtitle of the book indicated) “the evidence of evolution reveals a universe without design.” According to Dawkins, evolution shows that the universe and everything in it can be explained by undirected natural processes such as random mutation and survival of Read More ›
