Tea leaves and population substructure
Image credit: Wikimol Over the past few months I’ve been encouraging people to pull down ADMIXTURE, and push the public data sets through it. Additionally, you can also convert your 23andMe raw file into pedigree format pretty easily and integ…

The Nurture Assumption: Why Children Turn Out the Way They Do
Short comment: “Behavior genetics” you can use. Every potential parent should read this book.

The Language Instinct: How the Mind Creates Language
Short comment: An often forgotten gem in Steven Pinker’s oeuvre. More technical than The Blank Slate.

The Blank Slate: The Modern Denial of Human Nature
Short comment: Every college student should read this book. It’s a modern classic.

The 2007 crash in genome sequencing costs
Dr. Daniel MacArthur suggests: Now, we don’t want everyone working in genomics to start using the same blue-on-grey slide to illustrate the impending datapocalypse; so I’d encourage people to download the raw data (warning: Excel file) and make th…

Personal genome in the public domain
Image credit: Vikrum Lexicon Manu Sporny reflects on one week of being in the public domain in terms of personal genomics. I already pulled down his data, as has Zack. The whole post is fascinating, but this is really interesting: “I found out …

Media me
I’ve been rather busy this week, so few posts. But, I did a Bloggingheads.tv with Milford Wolpoff. We talk Out of Africa, Multiregionalism, and such. Second, The New York Times profiled Secular Right, where I’m a contributor. The quotes wer…

Friday Fluff – February 18th, 2011
1) First, a post from the past: A History of Iran: Empire of the Mind. 2) Weird search query of the week: “pictures of a famous woman drinking alcohol.” 3) Comment of the week, in response to D.I.Y. population structure inference, part 1…

Eurasia + Mozabites + Papuans
I’m in a hurry right now, and won’t be posting much this week. But, I thought I’d dump some of the ADMIXTURE runs I have. This is one with 80,000 markers, and Eurasian populations, Papuans and Mozabites. I removed the New World and Af…

Real three dimensional PCA!
Sort of. Check out what Doug McDonald’s done with javascript. The HGDP populations in three dimensions.

Culture differences matter (even within Islam)
I’ve been keeping track of events in the Arab world only from a distance. There’s been a lot of excitement on twitter and Facebook. Since I’m not an unalloyed enthusiast for democracy I’ve not joined in in the exultation. But I&…

Evolutionary Genetics
Short comment: Enough mathematical formalism to be technically illuminating, but not so much as to be opaque to the non-specialist.

Who are those Houston Gujus?
The figure to the left is a three dimensional representation of principal components 1, 2, and 3, generated from a sample of Gujaratis from Houston, and Chinese from Denver. When these two populations are pooled together the Chinese form a very homogen…

D.I.Y. population structure inference, part 1 of many
If you’ve been reading this weblog for a while you’ve seen many images like the one above. It comes from the 2008 paper Worldwide Human Relationships Inferred from Genome-Wide Patterns of Variation. The data set is from the Human Genome D…

A problem of aggregation of information
In a post below I regenerated the HGDP PCA plot you’ve probably seen around, except that I added my parents (and a few HapMap populations) into the plot. The PCA below was basically a visualization of the two largest independent dimensions of ge…

Friday Fluff – February 11th, 2011
1) First, a post from the past: Adaptation might not be a spherical cow. 2) Weird search query of the week: “shemale escort bald.” I’m not making this up. The user who searched for this is a Wiener. 3) Comment of the week, in respo…

“Inadvertent” incest detection?
Ruchira and Randall Parker point me to a new story about routine genomics screens detecting first degree incest: Beaudet wrote in the letter that “clinicians uncovering a likely incestuous relationship may be legally required to report it to chil…

D.I.Y. PCA
Long time readers know that I have a fixation on people not taking PCA too literally as something concrete. Tonight I finally merged the HGDP data set with some of the HapMap ones I’ve been playing with, and tacked my parents onto the sample. I…
