evolution
pharyngula | February 16, 2009Collins has argued that one piece of evidence for god is the human moral sense, which he claims could not have evolved. I guess we're going to have to call monkeys our brothers and sisters then, since researchers have found that monkeys have a sense of morality. (Let me guess; he'll just push the magic moment of ensoulment back another 30 million years.) Furthermore, they have explanations for how altruism could have evolved.
Some researchers believe we could owe our consciences to climate change and, in particular, to a period of intense global warming between 50,000 and 800,000 years ago.…
evolvingthoughts | February 16, 2009Myth 3: Darwin was actually a Lamarckian
This one is subtle. It implies that Darwin, because he lacked a Mendelian account of heredity, was not actually a "true" (or Neo-)Darwinian. The error depends on the extent of what is named as a school of thought in science and why.
As far as I know, the term "Lamarckian" for those who think heredity is acquired during the parental generation and passed on to progeny, was coined by August Weismann, a pre-genetics developmental biologist with an interest in heredity. He contrasted this with his own view, that germ cells - the cells in which inheritance…

In my last post I remarked on how "radically strange--and yet strangely modern" I expected the 1543 work that kicked off the "scientific revolution" to be. Now that I've read the first two books of De Revolutionibus, I can say, boy was I right.
This is the first of several posts about my experience of reading Nicholaus Copernicus in the original (er, translation). So first, let me point out the things I found "radically strange" about the work, with the "strangely modern" to come in the next post:
Radically strange: Instructions for how to build an astrolabe. Vast tables of star locations,…
gregladen | February 16, 2009So, yesterday Afternoon, there was a meeting of the Minnesota Atheists that included a one hour panel discussion of evolution, creationism, science education, and so on. The panel was moderated by Lynn Fellman, and included (in order from right to left as the audience gazed on) Randy Moore, Sehoya Cotner, Jane Phillips, Greg Laden, and PZ Myers.
There were several ways in which this discussion was interesting, and I'll tell you a few of them here. Presumably PZ will have something as well. (UPDATE: PZ has this.)
To begin with, this was a pretty full room (a hundred or so?) and almost…
razib | February 15, 2009Pew has the numbers:
The main surprise here are Mormons. I knew that they had become much more Creationist over the past 3 generations due to their identification with conservative Protestants, but I didn't know that it went this far. In The Creationists Ronald L Numbers states:
In 1935 only 36 percent of the students at the Mormons' Brigham Young University denied that humans had been "created in a process of evolution from lower forms." By 1973 the figure had risen sharply to 81 percent.
This is interesting because Mormons have no objections to evolution which are distinctively Mormon.…
palmd | February 15, 2009Science is hard. But science, and the methodological naturalism that underlies it, has proved to be the best way to observe, describe, and explain our reality. Sure, people can come up with ridiculous straw man arguments like, "but how do you measure love?" but these arguments ring hollow. (We measure "love", a behavior, by the observable behaviors that human beings report when they are "in love".) To a scientist, the appeal to magic to describe the world is difficult to understand, since the real puzzle is so much more fun. If, for example, you discover the cause of a particular disease…
clock | February 14, 2009On Thursday, for Darwin's 200th birthday, I went down to Raleigh to the Museum of Natural Science to hear Carl Zimmer's talk. The room was packed - I got the last empty seat and there were people standing in the back. A very mixed audience, as Museum talks usually are - there were evolutionary biologists there from Nescent and the W.M.Keck Center for Behavioral Biology at NCSU, there were Museum staff, and then there were interested lay-people, museum-goers, with no formal background in science but interested and curious. It is not easy giving a talk to such a mixed audience - how to keep the…
gregladen | February 14, 2009Feb 15 - Darwin Year Panel Discussion Featuring Myers, Laden, Moore, Cotner and Phillips
2009 marks the 200th anniversary of the birth of Charles Darwin and the 150th anniversary of the publication of On the Origins of Species. In honor of this, we have assembled a distinguished panel of scientists to give us their thoughts on evolution, creationism, and Darwin. The panelists are: PZ Myers, Randy Moore, Greg Laden, Sehoya Cotner, and Jane Phillips.
The discussion will be moderated by Lynn Fellman. Lynn is a frequent science interviewer on our Atheists Talk radio program. She is also an…
gregladen | February 13, 2009The Gallup Poll is not surprising in any of its results but it is, of course, alarming and interesting. Here's a summary.
On the eve of the 200th anniversary of Charles Darwin's birth, a new Gallup Poll shows that only 39% of Americans say they "believe in the theory of evolution," while a quarter say they do not believe in the theory, and another 36% don't have an opinion either way. These attitudes are strongly related to education and, to an even greater degree, religiosity.
The data:
Believe in evolution 39%
Do not believe in evolutoin 25%
No opinon either way 36%
Not surprisingly,…
pharyngula | February 13, 2009In a potentially exciting development, researchers have announced the completion of a rough draft of the Neandertal genome in a talk at the AAAS, and in a press conference, and the latest issue of Science has a number of news articles on the subject. And that is a reason for having some reservations. There is no paper yet, and science by press release raises my hackles, and has done so ever since the cold fusion debacle. Not that I think this is a hoax or error by any means, but it's not a good way to present a scientific observation.
Also, the work has some major limitations right now. They'…
mikethemadbiologist | February 13, 2009A recent paper in PLoS argues that variation in genes that regulate dopamine (5-HTTLPR) and serotonin neurotransmission (DRD4) influences financial risk taking: at the 5-HTTLPR gene, one homozygous form (two identical copies or alleles) took on 28 percent less risk, while those who had the '7-repeat' form of the DRD4 gene took 25 percent more risk. The Mad Biologist has issues regarding this study.
To me, the total amount of money the subjects could win (or not win) could influence the results. Someone who is risk adverse at $23 might be risk accepting at $2,300: if the participant were…
razib | February 12, 2009The Neandertal genome story is in the air. See The New York Times and Wired. Watch the press conference here.
terrasig | February 12, 2009This guest post comes to us from a colleague and friend, Dr Michael Wolfe. Enjoy!
The simultaneous celebrations of the 200th anniversary of the births of Abraham Lincoln and Charles Darwin today offers a special opportunity to reflect on the state of our democracy and the status of science in our society. That these two iconic figures were born on the exact same day is, of course, a coincidence. And yet, as often happens in life, a chance confluence of events can help us see connections that we might otherwise miss.
Today we lionize Lincoln as perhaps our greatest President, and his eloquent…
edyong | February 12, 2009This is the eighth of eight posts on evolutionary research to celebrate Darwin's bicentennial.
In Virginia, USA, sits a facility called the American Type Culture Collection. Within its four walls lie hundreds of freezers containing a variety of frozen biological samples and among these, are 99 strains of the common cold. These 99 samples represent all the known strains of the human rhinoviruses that cause colds. And all of their genomes have just been laid bare.
Ann Palmenberg from the University of Wisconsin and David Spiro from the J. Craig Venter Institute have cracked the genomes of all…
jrosenhouse | February 12, 2009By now you have surely heard that Charles Darwin turns 200 today. Happy Birthday! In honor of that fact, Darwin articles in various media outlets are currently a dime a dozen. Some good, some pretty bad, many just standard boilerplate.
Here's one that caught my eye, from The Times of London. It was written by Cormac Murphy-O'Connor and extols the virtues of blending faith with science. Let's have a look.
Towards the end of his life Darwin wrote: "It seems to me absurd to doubt that a man may be an ardent Theist and an evolutionist." The science opens me not only to puzzles and to…
bioephemera | February 12, 2009Yesterday I prepared to write my Darwin Day post by attending a panel discussion at the Center For American Progress here in DC. The discussion was ostensibly about "evolution, transcendence, and the nature of faith," which led my friend Colin and I to hope for a spirited debate - perhaps even a die-hard creationist who would speak for the three-quarters of frequent churchgoers who don't accept evolutionary theory! But what we got was a predictable, rather boring discussion - at least until David Sloan Wilson arrived and threw me for a loop.
The first two panelists were Rev. Dr. Susan Brooks…
gregladen | February 12, 2009... and made a real mess of the place when one of them spotted the jar of pickles on the counter. They fought over it until one of them had almost all the pickles and the other one had a number of bruises and a tiny fragment of one pickle that the other chimp dropped by accident.
That would be the way it would happen if two chimps walked into a bar. Or imagine two chimps, and each finds a nice juicy bit of fruit out in the forest. And instead of eating the fruit, because they are not hungry, they carry it around for a while (this would never happen, but pretend) and then accidentally run…
gregladen | February 12, 2009Mark Pagel, evolutionary theorist extraordinaire, has published an Insight piece in Nature on Natural selection 150 years on. Pagel, well known for myriad projects in natural selecition theory and adaptation, and for developing with Harvey the widely used statistical phylogenetic method (and for being a reader of my thesis) wishes Charles Darwin a happy 200th birthday, and assesses this question:
How has Darwin's theory of Natural Selection fared over the last 150 years, and what needs to be done to bring this theoretical approach to bear as we increasingly examine complex systems,…
