Testing the Orchard Model and the NCSE’s Claims of “Nested Patterns” Supporting a “Tree of Life”
In my previous post responding to the National Center for Science Education’s (NCSE) attacks on Explore Evolution‘s treatment of biogeography, I explained that there are many examples where there is inconsistency between evolutionary expectations of biogeography and plate tectonics. The NCSE is thus wrong to have claimed that “The consistency of these sorts of nested patterns cannot be explained without reference to common descent. The creationist ‘orchard’ is scientifically meaningless, since it makes no predictions.” * The classical “universal common descent” view is contrasted with the orchard model at below: The NCSE’s claim is perplexing because, as noted, the NCSE also claimed that “continuity [between biogeographic and evolutionary patterns] is what would be expected of a pattern of common descent, Read More ›
Will Tomorrow’s Academic Freedom Story in The New York Times Accurately Reflect Discovery’s Science Education Policy on Teaching Evolution?
UPDATE: A sentence in the original post has been corrected to read: I stopped her right there and explained that we do not favor mandating the teaching of intelligent design — as is so often misreported — but rather that we think when evolution is taught teachers should present both the evidence the supports Darwinian evolution as well as some of the evidence that challenges it. http://www.academicfreedompetition.comTomorrow The New York Times will publish an article about academic freedom bills being considered in a few states. We’ve obviously had some involvement: in 2008 we created the Academic Freedom Petition, which has sample language that legislators could adapt for use in their own states. That led to a very good piece of Read More ›
Sea Monkeys Are the Tip of the Iceberg: More Biogeographical Conundrums for Neo-Darwinism
In my previous post responding to the National Center for Science Education, I observed that the origin of South American monkeys (platyrrhines) is a striking example of a discontinuity between evolution and biogeography. As I observed at the end of that post, which was adapted from “The NCSE’s Biogeographic Conundrums: A Defense of Explore Evolution‘s Treatment of Biogeography“: the NCSE was not quite accurate when claiming that “By comparing macroevolutionary patterns between different groups, we find that the same patterns repeat. This strongly suggests that the same forces drove the diversification of those different groups.” The truth is that whenever oceanic “sweepstakes” dispersal is required, we find an exception to expected neo-Darwinian rules of biogeography. And as will be seen Read More ›
Sea Monkey Hypotheses Refute the NCSE’s Biogeography Objections to Explore Evolution
(Cartoon Courtesy of Pete Chadwell) In its response to the chapter on biogeography in the supplementary textbook Explore Evolution: The Arguments For and Against Neo-Darwinism (EE), the National Center for Science Education (NCSE) asserts that EE “mangles the tiny fraction of biogeography covered.”* My response to the NCSE’s arguments, “The NCSE’s Biogeographic Conundrums: A Defense of Explore Evolution‘s Treatment of Biogeography,” notes that “[t]he NCSE’s approach is to cherrypick examples to support their arguments for universal common descent, but a large number of ‘biogeographic conundrums’ that challenge neo-Darwinism could be discussed.” For example, in its response regarding marsupials, the NCSE admits, “If the [North American] opossum truly had roots in Australia, it would indeed be a biogeographic conundrum.” Since North Read More ›
A Malodorous Argument for Darwinian Evolution
University of California evolutionary biologist John Avise has penned a book, Inside the Human Genome: A Case for Non-Intelligent Design, and gotten it published by a top academic publishing house, Oxford University Press. Avise, a member of the National Academy of Sciences, has for decades been a leading researcher in evolutionary and ecological genetics. He has written hundreds of research articles and over a dozen books. Clearly he has an impressive scientific mind. Which makes it all the more astonishing that his new book shows all the intellectual savvy of a typical late-night college dormroom bull session. As his subtitle announces, Avise is anxious to show that, despite the claims of certain renegade biochemists, the molecular features of the human Read More ›
