Three-Spined Stickleback

Welcome to the Carnival of Evolution #18!

First off – big news here at the Carnival. As you can see, my edition is late again. I can’t seem to find the time to keep up online anymore (thanks alot starfish gene cloning). Thus it is with both disappointment and excitement that I am turning over administration of this carnival to Bjørn Østman of Pleiotropy. Bjørn has been a constant contributor to the CoE, and in his own last edition, he really rallied the troops and put out a great edition. He has shown such a constant passion for the subject that I have every confidence that the Carnival of Evolution will be much better in his hands than my own.

Now, all that being said, on with the show…

Research Blogging *or Literature Blogging

See – this is why I chose Bjørn to be the new organizer of this here carnival:
Bjørn Østman presents B:III evidence for evolution (which is just a theory) posted at Pleiotropy, in which he presents a Florida opthimologist’s ridiculous take on why evolution is not a fact. Bjørn’s funny summary of the guy’s publication:

“Here’s an outline of his letter:

1. Darwin quote-mining.
2. Probabilities, neglecting selection, assuming the eye is an accident.
3. “Consider that the eye…” is really complex.
4. “And where did X come from?” (Here, X = the chiasm.)
5. Haeckel’s drawings.
6. An analysis of rhodopsin molecule’s homology
7. The fruit fly is still a fruit fly.”
8. More Darwin quote-mining.

Zen Faulkes presents Extinction through fornication posted at NeuroDojo. Remember that classic case of sympatric speciation from college bio courses (yes I’m dating myself, here)? You know…the sticklebacks that were separating into benthic and pelagic forms? Well, apparently they’re back together as one happy thriving population, and it is perhaps due to the reintroduction of crayfish (”crawdads” for my fellow redneck southerners). A must read article.

Zen Faulkes presents Let your neurons relax, the predators are gone! posted at NeuroDojo, in which he discusses a recent paper testing the hypothesis that crickets living without bat predators will lose sensitivity in neurons primarily dedicated to detecting bats.

Shuna Gould presents Endosymbiosis – a big tangled mess of algae posted at Lab Rat. “Post on the symbiotic theory and the evolution of plastids, in particular how comprehensive phylogenetic analysis of diatoms and other protists has raised questions about the origin of chromalveolate symbionts” This post also talks about another favorite topic of mine right now: Horizontal Gene Transfer.

Evolutionary Discussion…

Dan presents Creationists and Birding posted at Migrations. In his own words: “I use the question of  ‘Can creationists appreciate the birds as much as evolutionists’ to explain the phenomenon of speciation from an ornithological standpoint.” I personally, found this to be a much more interesting read than I first expected from the title. There’s a good bit of history of evolutionary thinking in here, as well as a succinct answer to the posited question – one that any evolutionary biologist can hopefully predict.

Johnny presents Venomous Fables and Phenotypic Variations at the Molecular Level posted at Ecographica. I found this to be a truly entertaining post – not many could so easily wrap up thoughts on Heroditus’ war writings, an Aesop’s fable, discussion of the toxic cocktail in pygmy rattlesnake venom, and evolution all in one nice little package! As a timber rattlesnake researcher in my ancient past, I always hold such conversations a special place in my heart…

Surbhi Bhatia presents Eve is the Natural Ruler: Adam on verge of Extinction posted at The Viewspaper – an interesting discussion on the hypothesis that in 5 million years, the Y chromosome will disappear. I definitely learned a thing or two in this post, though I think the conclusion is presented a bit more foregone than should be.

John Suter presents Arachnid Lungs Evolved From Horseshoe Crabs posted at Kind of Curious. A short lesson on arachnid lung evolution, with discussion of a TV series I am also watching right now: Sir David Attenborough’s “Life in the Undergrowth.”

Andrew Bernardin presents Males Flashing Other Males posted at The Evolving Mind. Let me just reprint his first sentence – then you will go read his post:

“Any observer of nature will have noticed that many of the males are so colorfully “dressed” they seem ready to enter a gay pride parade.”

Andrew Bernardin presents How Life-Forms are Like Legos posted at The Evolving Mind. Could also be titled, “How proteins are NOT like legos.” Another great – and short – read.

That concludes this edition. CoE#19 will be hosted by the always superb and funny writer (and my friend) Christie Lynn at Observations of a Nerd.

For now, you can still submit your posts using our carnival submission form. This form may change – but you can always find out submissions information at http://carnivalofevolution.blogspot.com/.
