razib | September 1, 2006Inbreeding is bad. At least that is the take home message of my various posts. But biology doesn't have one final answer, it is a serious of approximations which capture part of a given system. My posts on racial hybridization point to this issue. Today in the West we live in an anti-racist age, so the intuitive benefits of hybridization known from agriculture are often tacitly promoted in the discourse, but the reality is more complex. 100 years ago eugenicists set out to prove the inverse because the norms of society demanded it (e.g., Charles Davenport's studies of Jaimaican Mullatoes…
razib | August 31, 2006As someone who makes no bones about being against politically correct evolutionary biology, I will take up RPM's call to link to Panda's Thumb's chapter-by-chapter rebuttal of The Politically Incorrect Guide to Darwinism and Intelligent Design. They fight Creationism so I don't have too!1
1 - I grew up around Creationists, so I've done the face to face "witnessing" enough in my life to believe I've put in my dues.
razib | August 31, 2006A reader pointed me to this fascinating, if tragic, article about the rise of rare recessive diseases among a schismatic Mormon sect which dominates Colorado City. This group has been in the news since the their "prophet" was just arrested. The article points out that because of the inbred nature of the community, and its small size, one particular rare disease, Fumerase Deficiency, has now become rather common. I have talked about inbreeding before. Most of us know the problems that crop up intuitively from experience, rare traits begin to spread in an inbred population. But, what needs…
razib | August 31, 2006Lubos Motl asked me to comment on this majestic post by a computational biologist at Stanford. This paragraph is worth quoting:
I will enumerate three main points, all of which represent both a challenge and an opportunity. The first will deal with a scientific challenge of a theoretical orientation, namely the lack of a theory for biology. The second with the sociological organization of biologists and biology departments at the leading research institutions. And the third will be part science, part sociology, having to do with the focus of current experimental methods and programs on…
razib | August 30, 2006I stand with the other science bloggers in encouraging everyone to do what they can to oust the Creationist on the Ohio School Board. More from Ed Brayton, Chad, John, Bora, Kevin and Tara. If you lose enough small battles the big war is lost.
razib | August 30, 2006In the 10 Questions for A.W.F. Edwards, a mathematical geneticist, he was asked:
Like Fisher you have worked in both statistics and genetics. How do you see the relationship between them, both in your own work and more generally?
Edwards responded in part:
Genetical statistics has changed fundamentally too: our problem was the paucity of data, especially for man, leading to an emphasis on elucidating correct principles of statistical inference. Modern practitioners have too much data and are engaged in a theory-free reduction of it under the neologism 'bioinformatics'.
This elicited a strong…
razib | August 30, 2006I noticed some blogs were talking about a new Pew Political Typology, and I decided to take their survey to see where I fit in. It said I was an Upbeat, which seemed wrong to me as I'm not that partisan (I voted for Kerry though my registration is Republican). So I took the Political Compass test, and I got my usual result:
Economic Left/Right: 2.13 (I'm fiscally conservative)
Social Libertarian/Authoritarian: -3.38 (I'm socially liberal)
I'm a moderate libertarian who leans toward the slightly more liberal side. My political intensity has been decreasing over the years, and I've probably…
razib | August 29, 2006To the right you see a habanero pepper, 100-350 K Scoville units (Jalapeno is 2.5-8 K). I can eat 2 habeneros in one sitting and enjoy it. And what does not kill you can cure cancer. Hot dog! On the other hand, if I want something which is a little less spicey and has a more tangy, aromatic flavor, I really enjoy green Thai peppers. I'm the spicey ScienceBlogger.
razib | August 29, 2006Look at this bitch. No, seriously, check it out, he has this long ass post on fossils and paleoanthropology. How the hell am I supposed blog about human evolution with some pride & self-respect if John Hawks has to cover every damn angle!!!. I know a little about fossils, words like stratigraphy don't terrorize me, but I just don't have all the details of every damn fossil at the Awash site or Sterkfontein in my head. Fossils make me want to tear my hair out, how the hell am I supposed to ascertain if the Hobbit is a new species or a pathology? Hawks on the other hand looks at…
razib | August 29, 2006Real Clear Politics has a column titled The Secular Right which reflects upon the Mac Donald vs. God affair. Interestingly, the author linked to my post where I followed the debate in The Corner. A few months ago my summary of John Derbyshire's summary of Judith Rich Harris' work was linked from her site. Ultimately, I think this should be a clue to NRO that they need to invest in a more robust and user friendly content management system: their archiving blows.
razib | August 29, 2006Check out the tour (taxonomy?) of the ScienceBlogs over at 3.14. There are promises of summaries of each SB (I assume I'll be the handsome ScienceBlogger!).
razib | August 28, 2006As a child it seemed that everyone preferred Lion Voltron to Car Voltron. I was a contrarian and asserted that I preferred Car Voltron, and yet in my heart of hearts I knew Lion Voltron was the true bomb. Is there an evolutionary psychological reason why Lion Voltron would be more popular than Car Voltron? I mean, there are lions on national flags, but cars? Lions play a role in mythology, and C.S. Lewis even selected a lion as a Christ analogue. Could it be cognitively lions give us more "free information" and inferential power? Could it be that Lion Voltron simply fit into a more…
razib | August 28, 2006Last week I pointed you to 10 questions for Luigi Luca Cavalli-Sforza, and hinted that there is another 10 Qs for another student of R.A. Fisher. Well, that time has come, today David B. posted his 10 questions for A.W.F. Edwards. I want to follow up last week's theme in regards to population substructure, because A.W.F. Edwards has been the most prominent recent expositer of why phylogeny, clustering of populations, is still possible though we are a genetically young and homogenous species. We asked A.W.F. Edwards on his motivations for writing Lewontin's Fallacy, and I think you'll find…
razib | August 28, 2006Recently, myself, RPM, afarensis, Robert Skipper, John Wilkins and John Hawks made about 10 assertions about evolution of about 10 words or less (some participants fudged, no worries, I'm not Tony Soprano). We all went in different directions, but issues that cropped up several times
* The relationship between selection and evolution, and its particular elucidation
* Mutation is not always deleterious
* Common descent of species
* Species concepts
* The fact that humans are still evolving
I haven't done a rigorous comparison, so your thoughts are welcome.
razib | August 27, 2006OK, so I finally read Coming to Life by Christiane Nüsslein-Volhard. Unfortunately, I am having a hard time finding something original to say. To recap, Janet, Shellee, Bora (hey, check out Bora's link, books_coming_to_life_by_christ.php!), RPM, The Poreless One and PZ hit this book hard. The reviews are damn thorough, and you have a wide disciplinary perspective, from neuroscience to developmental biology to evolutionary genetics to physiology to biochemistry, and over into philosophy. How's that for multidimensional?
So where does that leave me? Since I am so late already I figured I…

razib | August 26, 2006In an entry below I offer that the citation of a Wikipedia reference is not reliable, and I can't take responsibility if someone changes the entry between my link and your click. I am not totally kidding, I "Wikipediaed" a semi-famous individual recently and the entry described him as a serial rapist. In broken English. Someone was obviously bored, or had a bad experience with this small time celeb. I quickly reedited it, but it sure brought home to me the problem with Wikipedia. But then I thought: could you, as a blogger, just reedit or write your own Wikipedia entries and then link to…
