There are many ways one can model population genetic dynamics. A simple avenue is to imagine a deme, a group of breeding individuals, subject to a few major parameters which are modulating genetic variation. Mutation, migration, random drift and selection. A model being what a model is, one's goal…

In the post below on the Price Equation I stayed true to George Price's original notation in his 1970 paper where he introduced his formalism. But here is a more conventional form, the "Full Price Equation," which introduces a second element on the right-side.
Δz = Cov(w, z) / w
One can…

I notice more people have Google Wave now. What do you think? I keep leaving blank messages by mistake. Am I the only one?

In the comments below I referred to the "Price Equation." Here is what William D. Hamilton had to say about George Price's formalism in Narrow Roads of Gene Land:
A manuscript did eventually come from him but what I found set out was not any sort of new derivation or correction of my 'kin selection…

I have made reference to an epic fantasy series, The Wheel of Time, several times before on this blog. The series' author, Robert Jordan, died in 2007 and left the story incomplete. Jordan had made it to book 11 over the past 20 years, but the finale was left unwritten. So I hear, as I stopped…

Tom Rees, Income inequality drives church attendance:
...we find that attendance rates are particularly high in countries with more socioeconomic inequalities and fewer social welfare expenditure. This effect equally applies to both poor and rich people, which is in line with the idea that because…

He addresses the Behe diavlog. Sort of. McWhorter states that he did not find the rebuttals to the arguments in Michael Behe's Edge of Evolution persuasive. Fair enough, but I would be curious as to what other books on evolution he has read (I think he mentioned Sean Carroll?). The math in…

No Islamic Landmarks Were Harmed in the Making of '2012' (via Unreligious Right):
The trailer for 2012 plays like a highlight reel of civilization falling apart all over the world, but it's religion that gets the brunt of Emmerich's digital pounding: A Buddhist temple gets hit by a tidal wave. The…

In reviewing a paper which sketches out the boundary conditions under which group-level natural selection would result in the emergence of altruism as a genetically encoded trait, I stated:
... I would look to cultural group selection, because there are many cases of women being assimilated into a…

Another article on Creationism in Turkey:
To John Morris, president of the Institute for Creation Research in Dallas, however, the news could hardly be more encouraging.
"Why I'm so interested in seeing creationism succeed in Turkey is that evolution is an evil concept that has done such damage to…

I recently finished reading The Faith Instinct: How Religion Evolved and Why It Endures, a new book by Nicholas Wade, a science writer for The New York Times. Before giving it the "full treatment" I thought it behooved me to revisit some of the scientific literature which Wade relies upon to give…

Cooperation and individuality among man-eating lions.

As I gave a nod to statistical tricks and subtle shell games very recently, the material I review subsequently should be viewed with skepticism and caution. A few days ago I also pointed to a paper which describes and models intergenerational transfers of wealth across various societies. In other…

Early (2002) reader of Gene Expression, William Gunn, is leaving a biotech company in San Diego and is looking for another job. Here's his Linkedin.

I rarely post much political commentary here, because it would add little value as I have nothing distinctive to say in that domain. At Secular Right I am wont to do data analysis because I think data is something that needs to be injected into political discussions and commentary. But in any case…

Andrew Gelman has started a new blog at ScienceBlogs, Applied Statistics. Someone should design him a header, perhaps a fancified Bayes' theorem?

Spotted Piglet Hiccups: Boozy Breslin Clashes With Mosque:
The much-hyped, soon-to-open Breslin restaurant, situated in the 12-story Ace Hotel on Broadway and 29th, is giving members of the Masjid Ar-Rahman mosque across the street some agita. "Five times a day, there's a hundred cabs on the street…

In a piece that outlines SEC follies:
In fact, Mr. Madoff said in the jailhouse interview that, on two occasions, he was certain it was only a matter of days or even hours before he would be caught. The first time, in 2004, he assumed the investigators would check his clearinghouse account. He said…

Intergenerational Wealth Transmission and the Dynamics of Inequality in Small-Scale Societies:
Small-scale human societies range from foraging bands with a strong egalitarian ethos to more economically stratified agrarian and pastoral societies. We explain this variation in inequality using a…

Ruchira Paul has a post up, "Religious, superstitious, nonsense" and other harsh words. The point at issue is the fact that a teacher who expressed anti-Creationist views in harsh tones was sued. Ruchira asks somewhat rhetorically as to the sort of things parochial schools say about other religions…

I've discussed menopause as an adaptation and the grandmother effect before. I was also pleased to see the responses of Larry Moran's readers when he presented his standard anti-adaptationist line of argument. I don't want to retread familiar ground here, I'm not sure if menopause is an adaptation…

In the wikipedia entry for "ballad" there's the image with caption to the left. Am I weird for finding that just really, really, funny? I start having these weird flashbacks to lots of pink hair,screaming weirdos, and Every Rose Has Its Thorn. Am I the only one who feels that the fashions and…

Carl Zimmer points me an article about a former anthropologist who has some weird ideas about the origin of man:
Since his resignation from the university in 1990, however, Horn has changed his tune. Once a staunch Darwinist and tenured CSU anthropology professor, Horn has devoted the last 19 years…

The Spittoon points to a new paper, Drawing the history of the Hutterite population on a genetic landscape: inference from Y-chromosome and mtDNA genotypes, which I've been meaning to look at more closely. Unlike some attempts to use genetics to illuminate questions about the human past here the…

There's something cool about Canada, I just found out that Alberta is the only large region of permanently inhabited human territory which lacks brown rats. One thing you have to remember is that the brown rat only began spreading within the last 1,000 years (in the process displacing the black rat…

This critique by Ted Goertzl, Myths of Murder and Multiple Regression, is making the rounds. It made me think of this old apocryphal story:
There is a famous anecdote inspired by Euler's arguments with secular philosophers over religion, which is set during Euler's second stint at the St.…

Dr. Thomas Mailund has posted a YouTube interview of Svante Paabo. Looks like the previous post was off-base, though I'm not really totally sure.
