Gene Expression

So, I tried out Dave’s Insanity Hot Sauce with some Tuna pasta yesterday. Here’s a comment from Amazon: “I am a real fan of hot sauce, hot peppers and anything that makes my eyes water, and I have to honestly say that Dave’s Insanity Sauce is absolutely the hottest thing I’ve ever tasted. I use…

7 days of hot sauce

Regular readers know that I’m really into smokin’ hot sauces. I mean real hot. I’m the guy who the chefs at the local Thai restaurant know well enough to get their habanero paste ready for the medium rare steak flank. I’m the guy who checks out the local organic or Mexican grocery store for habanero…

European population substructure

The American Journal of Human Genetics has an article up examining population substructure within Europe (or, more precisely, the varation of genes), Measuring European Population Stratification with Microarray Genotype Data. From the discussion: PC1 [the largest principle component of variance] largely separates northern from southeastern individuals…and is consistent with the clines observed in classic gene-frequency…Y-chromosome…mtDNA…and…

Is religion an adaptation?

Paul Zed Myers comments on Alan MacNeill’s contention: To an evolutionary biologist, such pan-specificity combined with continuous variation strongly suggests that one is dealing with an evolutionary adaptation. Myers sayeth: For another example, people in the US largely speak English, with a subset that speak Spanish, and a few other languages represented in scattered groups.…

Over at GNXP Classic David B has an introductory preface to a series of posts he plans to write on the great evolutionary geneticist Sewall Wright. David sums up: As for my own assessment, for what little it is worth, in reading Wright I have realised that his achievement was truly massive. At the same…

One issue that has cropped up in the comments a few times here is a conflation between quantitative & population genetics. Though people seem to think they’re interchangeable terms, they’re distinct fields. That’s why population genetics text books have chapters devoted specifically to quantitative genetics, and showing how the latter can be bridged with the…

I really don’t know what to think of this. Did you catch Zach Braff debating CATO’s Will Wilkinson? Either Scrubs isn’t doing so well, or Robert Wright is so big that semi-intellectual actors want to get aboard with bloggingheads.tv.

SLC45A2 and human skin color

I figured I would just note this, another skin color study: …We previously reported significant associations of two coding region polymorphisms with hair, skin, and eye color in Caucasians. Here we characterize the promoter region of MATP [SLC45A2] identifying two new transcription start sites and a novel duplication…A total of 700 individuals from five different…

The Prison of War & Peace

A few days ago I began a survey of Martin Nowak’s treatment of modern game theory in his book Evolutionary Dynamics. Today I’m going to hit the Prisoner’s Dilemma. Roughly, this scenario is one where two individuals are isolated, and if they both keep their mouths shut (cooperate) they get off, but, if one rats…
