hrynyshyn | February 9, 2009Not to diminish Charles Darwin's brillance in the slightest, but there's a nice little essay in the New York Times by Nicholas Wade that helps explain why the guy managed to get so much so right so long ago. The money quote:
One of Darwin's advantages was that he did not have to write grant proposals or publish 15 articles a year. He thought deeply about every detail of his theory for more than 20 years before publishing "The Origin of Species" in 1859, and for 12 years more before its sequel, "The Descent of Man," which explored how his theory applied to people.
So what need are more and…

It's out! Evolution vs. Creationism: An Introduction (Second Edition) is now available on line and in bookstores (or at least it is being shipped out as we speak).
This is the newly revamped edition of Genie Scott's essential reference supporting the Evolutionist Perspective in the so called "debate" over creationism vs. evolution. The original version of this book was excellent, but this updated version is essential. There is quite a bit of new information in this volume reflecting the fact that quite a few things have…

In our world, there is (roughly) one man for every woman. Despite various social differences, our gender ratio remains steadfastly equal, so much so that we tend to take it for granted. Elsewhere in the nature, things are not quite so balanced.
Take the blue moon butterfly (Hypolimnas bolina). In 2001, Emily Dyson and Greg Hurst were studying this stunningly beautiful insect on the Samoan islands of Savaii and Upolu when they noticed something strange - almost all the butterflies were females. In…

As you may remember, this week we have a special guest here in the Triangle - Carl Zimmer is coming to enjoy NC BBQ and, since he's already here on the 12th, to give the Darwin Day talk at the North Carolina Museum of Natural Sciences in Raleigh (directions):
"Darwin and Beyond: How Evolution Is Evolving"
February 12, 2009
6:30 pm - 7:30 pm
Please join us for a Darwin Day presentation by Carl Zimmer. Mr. Zimmer is well known for his popular science writing, particularly his work on evolution. He has published several books including Soul Made Flesh, a history of the brain, Evolution: The…
gregladen | February 9, 2009When reading the Voyage, it is impossible to miss the observation that much of the time Darwin was engaged in adolescent boy behavior: Pulling the heads off insects, noting how long they would wiggle after cut in half, closely examining the ooze and guts, occupied much of his time. Obviously, careful observation and a strong stomach were not all that was required to think up Natural Selection and his other theories, or the Origin of Species would have been written dozens of times by dozens of grown up kids.

jwhitfield | February 9, 2009From the first dawn of life, all organic beings are found to resemble each other in descending degrees, so that they can be classed in groups under groups.
Isn't that a good sentence? It's the first of this chapter. There's music in the way the Biblical ring of "From the first dawn of life", falls towards the swallowed repetition of "groups under groups", which itself mirrors and explains the descending degrees of resemblance that gives the sentence its scientific filling.
The next line is just as good: "This classification is evidently not arbitrary like the grouping of the stars in…
cmooney | February 9, 2009So...it is not exactly easy to find history of science classics at your average--or even your well above average--bookstore.
The class I'm officially taking here at Princeton, History 293, focuses heavily on a course packet and so doesn't have many officially assigned books. It does have a few; they are Darwin's Voyage of the Beagle and Origin of Species--which I already own and have read, although right now they're somewhere in the middle of the country in transit--and Michael Adas's Machines As the Measure of Men: Science, Technology, and Ideologies of Western Dominance (Cornell Studies in…

What do you get when one species splits into separate lineages? Two species? Think bigger...
When new species arise, they can set off evolutionary chain reactions that cause even more new species to spring forth - fresh buds on the tree of life create conditions that encourage more budding on different branches.
Biologists have long suspected that these "cascades of speciation" exist but have struggled to test them. Enter Andrew Forbes from the University of Notre Dame - his team of has found a…

The life and times of Charles Darwin -- a failed student from a rich family whose five year voyage round the world inspired The Origin of Species, a groundbreaking work outlining the theory of evolution. Dr. Chapman explains how Darwin's ideas caused outrage in polite society at the time. [9:08]
pharyngula | February 8, 2009And I don't want to hear you complaining that everything makes me cranky! I get especially grumpy about armchair futurists making pronouncements about biology when they don't know a thing about it.
Chairman and CEO of Biotechonomy, Enriquez says that humanity is on the verge of becoming a new and utterly unique species, which he dubs Homo Evolutis. What makes this species so unique is that it "takes direct and deliberate control over the evolution of the species." Calling it the "ultimate reboot," he points to the conflux of DNA manipulation and therapy, tissue generation, and robotics as…

If you were a designer tasked with creating a machine for collecting and processing light, the last thing you would come up with is the human eye. Darwin marvelled at the eye as an "organ of extreme perfection", but in this, he was wrong. Aside from the many illusions that can fool them, our eyes have a major structural flaw. In humans and other back-boned animals, the light-sensing cells of the eye - the "photoreceptors" lie at the back of the retina.
In front of these sensors lie several…

The Birdbooker Report is a special weekly report of a wide variety of science, nature and behavior books that currently are, or soon will be available for purchase. This report is written by one of my Seattle birding pals and book collector, Ian "Birdbooker" Paulsen, and is edited by me and published here for your information and enjoyment. Below the fold is this week's issue of The Birdbooker Report which…
laelaps | February 7, 2009Now this is pretty cool. Since 2007 the Australopithecus afarensis skeleton AL 288-1, that's "Lucy" to you and me, has been on tour in an exhibit called "Lucy's Legacy - The Hidden Treasures of Ethiopia." I don't know if the exhibit is going to come close enough to me to allow me to visit it, but thanks to the website eLucy, I can look at the skeleton from home.
Hosted by the University of Texas at Austin, the website allows you to compare Lucy's bones with those of a human or a chimpanzee. This is a great resource for anyone who has been aching for a closer look at the fossils than is often…
pharyngula | February 6, 2009I know! It's hard to believe! Why, any of the riff-raff can just charge in and start a blog anymore. You write a book or a few, do some internationally recognized research in evolution, and suddenly you get cocky and think you have the talent to write a blog. Back in the day when I started in this, I had to struggle with none of that. And I liked it!
Despite his awesome handicaps, it is a pretty good blog.
I especially like this image from his book, Why Evolution is True(amzn/b&n/abe/pwll):

jwhitfield | February 6, 2009Back when I started this, I remarked that one of the reasons I hadn't read the Origin was that I couldn't imagine it being essential to a grasp of contemporary science. Regarding evolution, I think you could still make a case for this. But in other ways, that statement shows that you really shouldn't opine on topics you know nothing about.
Specifically, I'm talking about ecology (by which, just to be clear, I mean the study of the interactions of living things with each other and their environment, rather than 'nature' or 'environmentalism'). It's been said that all European philosophy is a…
gregladen | February 5, 2009I want to bring your attention to a somewhat dense and possibly inconclusive (but important) paper accompanied by a very informative overview in PLoS Biology, concerning mutations in the human genome.
Mutation rates and patterns of mutation are important for a number of reasons. For one thing, the genome itself is a data set that is both broad and deep. There is a lot of information in a given individual genome (a haploid set of genes from a person, for instance) but there is a wide range of variation in that information. So, inferences or assertions regarding the nature and distribution…
jlynch | February 4, 2009February is going to be a busy month for me. Sunday I leave for Oklahoma where I will be giving the lead-off public lecture for their Darwin 2009 Celebration. I will be speaking on the 12th at the Sam Noble Oklahoma Museum of Natural History on the topic of “Was There A Darwinian Revolution?” Any Sooner readers should feel free to come along and introduce themselves.
While in Norman, I’ll also be teaching a four-day intensive course on Darwin for the Oklahoma Scholar-Leadership Enrichment Program, the syllabus for which is here. While there will be some lectures, the meat and potatoes of the…

gregladen | February 4, 2009Of his time on the Beagle (1832 - 1836), Darwin wrote, "The voyage of the Beagle has been by far the most important event in my life and has determined my whole career." Of the manuscript describing that voyage, he wrote, "The success of this my first literary child always tickles my vanity more than that of any of my other books."
Taking a cue from these reflections, I'd like to spend some time with this book, in celebration of Darwin's 200th birthday, coming up in just a few days.

gregladen | February 4, 2009The complete genome of a Neanderthal dating to about 38,000 years ago has been sequenced by the team lead by Svante Paabo. The genome will be announced on Darwin's Birthay, Feb 12.
"We are working like crazy at the moment," says Pääbo, adding that his Max Planck colleague, computational biologist Richard Green, is coordinating the analysis of the genome's 3 billion base pairs.
Comparisons with the human genome may uncover evidence of interbreeding between Neanderthals and humans, the genomes of which overlap by more than 99%. They certainly had enough time for fraternization -- Homo…
