I was just catching up on a few blogs, and noticed all this stuff I missed about Jonathan Wells' visit to Oklahoma. And then I read Wells' version of the event, and just about choked on my sweet mint tea.
The next person--apparently a professor of developmental biology--objected that the film ignored facts showing the unity of life, especially the universality of the genetic code, the remarkable similarity of about 500 housekeeping genes in all living things, the role of HOX genes in building animal body plans, and the similarity of HOX genes in all animal phyla, including sponges. 1Steve began by pointing out that the genetic code is not universal, but the questioner loudly complained that 2he was not answering her questions. I stepped up and pointed out that housekeeping genes are similar in all living things because without them life is not possible. I acknowledged that HOX gene mutations can be quite dramatic (causing a fly to sprout legs from its head in place of antennae, for example), but 3HOX genes become active midway through development, 4long after the body plan is already established. 5They are also remarkably non-specific; for example, if a fly lacks a particular HOX gene and a comparable mouse HOX gene is inserted in its place, the fly develops normal fly parts, not mouse parts. Furthermore, 6the similarity of HOX genes in so many animal phyla is actually a problem for neo-Darwinism: 7If evolutionary changes in body plans are due to changes in genes, and flies have HOX genes similar to those in a horse, why is a fly not a horse? Finally, 8the presence of HOX genes in sponges (which, everyone agrees, appeared in the pre-Cambrian) still leaves unanswered the question of how such complex specified genes evolved in the first place.
The questioner became agitated and shouted out something to the effect that HOX gene duplication explained the increase in information needed for the diversification of animal body plans. 9I replied that duplicating a gene doesn't increase information content any more than photocopying a paper increases its information content. She obviously wanted to continue the argument, but the moderator took the microphone to someone else.
It blows my mind, man, it blows my freakin' mind. How can this guy really be this stupid? He has a Ph.D. from UC Berkeley in developmental biology, and he either really doesn't understand basic ideas in the field, or he's maliciously misrepresenting them…he's lying to the audience. He's describing how he so adroitly fielded questions from the audience, including this one from a professor of developmental biology, who was no doubt agitated by the fact that Wells was feeding the audience steaming balls of rancid horsepuckey. I can't blame her. That was an awesomely dishonest/ignorant performance, and Wells is proud of himself. People should be angry at that fraud.
