Quote-mined by Casey Luskin!

Once again, Casey Luskin demonstrates that he’s a biological ignoramus. He is much buoyed by a science report that chloroquinone resistance in the malaria parasite requires two mutations, claims that Michael Behe has been vindicated because that’s exactly what he said, and demands an apology from all of Behe’s critics. Will Ken Miller, Jerry Coyne,…

The debate about intelligent, extra-terrestrial aliens goes on, with the usual divide: astronomers insisting that the galaxy must be swarming with alien intelligences, which is popular with the media, and the biologists saying no, it’s not likely, there are probably swarms of single-celled organisms, but big multicellular intelligences like ours are probably rare. And the…

Stinky stuff! This fits perfectly with my biased preconceptions. So here are two examples of chemistry used to analyze things you’d normally run away from. The oldest traces of human poop have been dug out of a cave in Spain — and it’s Neandertal poop. It’s about 50,000 years old, and it’s been reduced to…

Deconstructing metaphors

Oh, that’s right — that’s what philosophers are good for. They’re really good at questioning models. John Wilkins has been busily dismantling the cheap and easy metaphors we use to describe molecular biological concepts in a series of posts, taking on genes as language, other popular gene myths and metaphors, and explaining why genes aren’t…

Multi-component, schmulti-component

I’m having a light dinner while traveling off to a visit with Humanists of Minnesota, and I thought I’d deal with a little email. I got a request to address a fairly common creationist argument–here’s the relevant part of the claim. As a member of the Greater Manchester Humanists I was recently involved in a…

This is the paper to read: Palazzo & Gregory’s The Case for Junk DNA. It clearly and logically lays out the complete argument from evidence and theory for the thesis that most of the genome is junk. It’s not revolutionary or radical, though: the whole story is based on very fundamental population genetics and molecular…

Irreducible complexity, again?

We’ve had a creationist named “biasevolution” babbling away in the comments. He’s not very bright and he’s longwinded, always a disastrous combination, and he tends to echo tedious creationist tropes that have been demolished many times before. But hey, I’m indefatigable, I can hammer at these things all day long. He brings up irreducible complexity…

He hates Tiktaalik. He hates it so much he even has a hard time spelling its name correctly. Tikaalik is again being popularized through the new PBS series "Your Inner Fish.” it’s really a desperate con job on the part of evolutionists who can’t defend their evolutionary fictional story. He actually surprises me a little…

I was looking over the Discovery Institute’s Evolution News and Views site, prior to forgetting about it. I mentioned that I am forced to revamp my email handling and was going to be blocking a lot of noise from my work address, and as I was reviewing what domains I needed to allow through, I…

I was rather surprised yesterday to see so much negative reaction to my statement that there’s more to evolution than selection, and that random, not selective, changes dominate our history. It was in the context of what should be taught in our public schools, and I almost bought the line that we can only teach…
