Foot adaptation….

Below is an image which offers evidence for functional analysis in the context of The Pliocene Pussy Cat Theory.

Genetics + coffee = death…or…not

Interesting paper out in JAMA, Coffee, CYP1A2 genotype, and risk of myocardial infarction: The association between coffee intake and risk of myocardial infarction (MI) remains controversial. Coffee is a major source of caffeine, which is metabolized by the polymorphic cytochrome P450 1A2 (CYP1A2) enzyme. Individuals who are homozygous for the CYP1A2*1A allele are “rapid” caffeine…

John Hawks on the radio

You want to know what John Hawks sounds like? He’ll be on Radio Open Source tomorrow (there should be a web feed). I talked to David Miller about getting John on the show before he became famous in Slate, so I am going to take a little credit for this. John and Spencer Wells will…

Fat men are dumber!

I have a maxim, “beware of British newspapers.” I guess I should add the BBC to that list after reading this slapdash piece, Obese men ‘have lower IQs’. Speaking as a normal weight individual with a BMI of 22.8 I don’t have a personal axe to grind, but this study screams correlation does not equal…

I am evil

Very evil in fact. See below. Via Afarensis.

Terror from the heights

Below is an image that should strike fear into the hearts of all birds, from below and above, evil knows no bounds! On a serious note I was chatting with a friend of mine about the possible hypotheses for the domestication of the dog, and when we moved onto cats he remarked that I’d had…

Interesting report out, Evolutionary biology research techniques predict cancer. Medicine has been around for thousands of years, from the “healings” of shamans to the “theoretical” paradigm of Galen. It seems possible that until the last 100 years or so medical techniques were just as likely (or more likely in many situations) to exacerbate illnesses as…

George W. Bush, Randian superman?

This whole conversion story in Afghanistan has been in the news recently. The Christian Science Monitor attempts to put the issue of conversion from Islam to another religion in an international perspective. I am cautious about making large generalizations without qualifications, but I will offer that as a civilization, “Dar-al-Islam,” has particular issues with conversion…

Apropos of my earlier post relating to heritability…this is the sort of confusing gibberish that ends up making it into the press, Professor researches genetics of gambling. He tries to clear up problems of communication: This quote has been misconstrued. In the logical development of any investigation of the genetics of a disorder, once something…

Come the reductionist revolution….

There is an important paper out on calculating heritability (JAVA applet). Heritability is an important and misunderstood concept. Some people have argued that heritability is fallacious reification, a biostatistical construct which has no real relevance (or reality) outside of its utility in quantitative genetic models. But its entwinement with various concepts within evolution and genetics…
