Evidence is always the best way to resolve a debate

You know how we great clumsy gallumphing unsophisticated atheists are always comparing belief in gods to belief in fairies at the bottom of the garden or tooth fairies or whatever? We may have to revise those arguments.

Now we really have to worry. If some space probe snaps a picture of an orbiting teapot, we’ll have nothin’.

Crap. Sean knocks the props out from under my godlessness. Now I’m going to have to convert to something…what does everyone recommend? Catholicism, LDS, Scientology, etc., or should I just go all the way primitive, erect a phallus-shaped rock in my backyard, and start worshipping that?

Womb with a view

i-c9182c3edcb1c39b63ae9e8c27a57286-dolphin_embryo.jpg

The BBC is going to be showing a program with images of developing embryos (there are some galleries online) generated from ultrasound, cameras inserted into the uterus, and largely, computer-generated graphics. It’s all very pretty, and I hope it will also be shown in my country, but…these pictures violate all the rules of scientific imaging. The images are clearly generated by imposing artistic decisions derived from the conventions of computer animation work onto the data that was collected—I can’t tell what details in these embryos were actually imaged, and which were added by the CGI guy.

I can tell you that the way they’re rendered as free-floating individuals suspended in great airy spaces lit by a glow through distant membranes like stained glass windows is complete hokum, and the textures just look all wrong. They ought to be slimy, wrapped in membranes, and enveloped closely in maternal tissues. I hope the program includes some honest description of the process of making the images, with before and after photos, so viewers can see how much of the work is interpolated and artificially added.

Australian Lungfish update

I just received word from Per Ahlberg that the status of the Australian lungfish conservation efforts have reached a critical phase: letters are needed NOW. Here’s the situation:

The Traveston Dam proposal has moved into a new and critically important phase: it has been referred to the Federal Environment Minister (Mr Ian Campbell) for consideration under the Federal Environmental Protection and Biodiversity Conservation Act. Ian Campbell has the power to stop the dam, but if he doesn’t it is unlikely that any other organisation or individual will be able to do so.

The first hurdle that must be crossed in order to stop the dam is to ensure that the Minister does not allow the Queensland Government to conduct the EPBC assessment of it’s own proposal – something that he is entitled to do. This would be a recipy for disaster as they would be certain to conclude that their own proposal is environmentally sound! The assessment must be carried out by the Federal Environment Ministry to ensure a proper process.

The Save the Mary River Campaign is asking supporters to write to Mr Campbell and a number of relevant senators to demand a proper assessment, and provides some very helpful information and instructions. This is URGENT: letters have to be received before 27 November.

You can get details here—start writing!

MADS boxes, flower development, and evolution

i-ccbc028bf567ec6e49f3b515a2c4c149-old_pharyngula.gif

I’ve been writing a fair amount about early pattern formation in animals lately, so to do penance for my zoocentric bias, I thought I’d say a little bit about homeotic genes in plants. Homeotic genes are genes that, when mutated, can transform one body part into another—probably the best known example is antennapedia in Drosophila, which turns the fly’s antenna into a leg.

Plants also have homeotic genes, and here is a little review of flower anatomy to remind everyone of what ‘body parts’ we’re going to be talking about. The problem I’ll be pursuing is how four different, broadly defined regions of the flower develop, and what that tells us about their evolution.

Arks and Tangled Banks

The Tangled Bank

There don’t seem to be a lot of carnival notices in my mailbox today, so I’ll just note that the Friday Ark #113 is up, and remind everyone that the next Tangled Bank is coming up on Wednesday, at Newton’s Binomium (by the way, I thought his post on the difficulty of explaining the importance of evo-devo was good—there are biologists who look utterly blank at the enthusiasm the subject generates in some of us). Send stuff to host@tangledbank.net or me by Tuesday.

The sea urchin genome

Oh happy day, the Sea Urchin Genome Project has reached fruition with the publication of the full sequence in last week’s issue of Science. This news has been all over the web, I know, so I’m late in getting my two cents in, but hey, I had a busy weekend, and and I had to spend a fair amount of time actually reading the papers. They didn’t just publish one mega-paper, but they had a whole section on Strongylocentrotus purpuratus, with a genomics mega-paper and articles on ecology and paleogenomics and the immune system and the transcriptome, and even a big poster of highlights of sea urchin research (but strangely, very little on echinoderm development). It was a good soaking in echinodermiana.
