Mike Gene has posted an interesting series on introns that's worthy of a few comments. His thesis is that "introns facilitated the evolution of multicellular life." A. The idea is interesting and rational but not novel.
So Stephen Meyer of the Discovery Institute, a founder of the ID movement, wrote a book called Signature in the Cell: DNA and the Evidence for Intelligent Design. It came out last summer, and I ignored it. I ignored it because it didn't seem interesting or important or new, and there's always something interesting and important and new to read. (I recently finished The Road.
Welcome to Quintessence of Dust and to the 14th Edition of the monthly Carnival of Evolution. Thanks for stopping by, and for supporting scientific carnivalia, members of a taxon that seems to be flirting with extinction. One good reason to visit a carnival: brain stimulation.
Hello and welcome to the 28th edition of the genetics blog carnival known as Mendel's Garden, where we celebrate blogging on topics related to anything touching on what Mendel discovered (or thought he discovered). While reading these interesting and informative pieces, please think about work that should be featured in a future edition and/or blogs (like yours) that would serve well as future hosts. So do tomato seeds get you excited? No? Oh.
About 2 months ago, I finished a series on Michael Behe's latest book, The Edge of Evolution. I concluded that it was a terrible book, displaying significant errors of both fact and judgment. The book's main argument is a population genetics argument, and Behe seems to have little knowledge or understanding of that difficult subject.
It's exciting to live in the era of evolutionary genomics, when new genomes are being published approximately once a week, and the light of genomic analysis is being trained on more and more branches of the tree of life.
Charles Darwin collected all sorts of cool stuff (like a vampire bat, caught while feeding on his horse) on his journey aboard the Beagle, and it has to be said that he understood little of it until after he got back. The finches that bear his name were identified as such by someone else, and his own bird collections from the Galapagos were nearly worthless due to the fact that he hadn't bothered to label specimens as to their place of origin.
The wing of a bat is an amazing thing. It's not just a wing; it's clearly a modified mammalian limb. A bat looks like a lot like a rodent with really long, webbed fingers on elongated arms. Image from Animal Diversity Web at the University of Michigan.
It'll be a breakout week after a slow month on the blog. To the Edge of Evolution – and beyond! Ian Musgrave over at Panda's Thumb provides a nice summary of the evolution of clotting systems and some new genomic data that could be used, by ID proponents like Michael Behe, to bolster their claims regarding the "irreducible complexity" of the clotting system.
Last quiz on genome size, with animals chosen at random. The first quiz post explains what this is all about, the second one has additional commentary, and the answers to both previous quizzes are in previous Weekly samplers. Which organism has the larger genome? This one? Or this one? 1 2 3 4 Here's some help for you.
