UPDATE* if you do not see your post mentioned, see note at the bottom of the post.
The long awaited, much delayed eighth edition of the Carnival of Evolution is here.
I won't go into the excuses, other than to say that one of them was the death of my grandfather - a man whose love of nature inspired my own long journey into biology.
However, what better timing to resurrect a blog carnival devoted to evolution than now, a mere 12 days from Charles Darwin's 200th birthday in the year of the 150th anniversary of the publishing of On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.
The second question you should ask is "am I signed up for the Blog for Darwin campaign on February 12th-15th, and if not, why not?"
Before we get into the wonderful evolutionary linkage, you should all first refresh your memories on the origins of the theory of natural selection by doing what I am doing: re-reading "Origin." Go ahead...I'll wait.
While we're waiting for those who just left to dig up their old tattered copies or purchase new ones, the rest of you might do just as well by visiting "Blogging the Origin" by John Whitfield, in which he gives an incredibly entertaining rundown of each chapter in the seminal book.
We all on the same page now? Good.
What? We're NOT all on the same page? Oh that's right, as the fellows at Astroguyz.com reminds us in a new review of that atrocious diatribe against evolutionary theory, Expelled, some people are still on the wrong book. My favorite caption from said post: "Are you there, Darwin? (Its me, Ben.)"
Or perhaps they will find a truth that is not ours. A real truth in which a giant cuttlefish lies behind the mysteries of life, surrounding them with slimy tentacular truthpendages. Though I doubt anyone but the Digital Cuttlefish could ever find such truth.
Ah well, at least we still have groups such as the folks over at Portland State affirming the last 150 years of truth for us, via the ALWAYS entertaining Peter Buckland over at Forms Most Beautiful. As an aside, I love Peter's blog name, for it comes from one of the most wonderful quotes from our illustrious 19th century hero. In fact, it is the concluding sentence of the entire Origin of Species:
"There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone circling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.”
So why should we care that some have not found that unifying theme of all life on the planet, present and past? Why does evolution even matter?
Well, for one, as an excellent biology teacher over at FYI: Science! reminds us (in the first of a multi-part series on why evolution matters), evolution is the reason you should all stop buying all those antibacterial soaps and stop taking antibiotics for a viral infection. She also lets us not forget that without the wonders of evolution, we would never have survived the nineties without our favorite paleontologist, Ross, from Friends.
Without evolution, could we really expect to have things such as a parasite that causes the loss of a fish's tongue, promptly replacing said tongue with itself? This wondrous science-fiction parasite (only one example in a series of such beautiful monstrosities at Observations of a Nerd) makes Douglas Adams' Babel Fish seem downright plausible.
Without a thorough understanding of evolution, one might be tempted to rationalize gender inequalities in human society using only partially understood naturalistic worldviews. Luckily, evolution has produced a perfect antidote to this way of thinking in the form of the masterful writer, Greg Laden of Greg Laden's Blog.
There is also personal power to be gained in understanding nature and its evolutionary history. To quote Asmoday of The Asmoday Experiment in an hilarious and entertaining post on our primate nature
You can become incredibly powerful by watching monkies.
Yes, I am dead serious here.
Ahh, but lest I give our non-biologist readers the wrong impression, I must note that not a day passes in which some new startling, fascinating, bewildering, strange, or subtle new piece of our planet's evolutionary history does not reveal itself to empirical eyes. And in this month's edition we have a plethora of newly published studies unraveled for us by none other than GrrlScientist at Living the Scientific Life. From the convergent evolution of the Hawai'ian Honeyeaters, the evolution of yawning as a thermoregulatory mechanism, and the discovery of a new Argentinian carnivorous dinosaur to the origins of modern birds, GrrlScientist lays the glory of the data out for us all to see, and most importantly, understand.
Taking a deeper view and delving into the molecular origins of the origins themselves, Hoxful Monsters brings us an excellent review of the importance of the ParaHox genes, paralogous to the familiar Hox cluster. In a related post, he brings us details of a recent study that places the Hox-lacking ctenophores, the beautiful creatures of the sea, as the most primitive of animal groups.
Yet these findings are all mere glimpses into the wonders of the fruits of natural selection.
What will we uncover next?
Please note, after discussion with several other bloggers at ScienceOnline09, including the Deep Sea News writer and hilarious musician Kevin Zelnio, the Carnival of Evolution will now be published on a monthly basis instead of biweekly. This is to both increase the quality of the carnival and to increase the number of entries in each edition. The conference was reinvigorating to say the least and I am committed to making sure this Carnival remains successful.
*UPDATE* 1/30/09 - After I published this, I found that blogcarnival.com had backlogged a whole other set of submissions (quite alot actually) for edition #9 (the one after this). If your post is one of these I am SO sorry. They were not included because I did not know they existed! I will set up another edition devoted to this full set of links ASAP. This is actually pretty exciting because it means we have ALOT more submissions than I thought! Woo hoo!
*UPDATE* 2/3/09 - PART TWO of this edition is now posted here: Carnival of Evolution #8 (Part Two).
