Introgression in wolves & dogs

Apropos of our discussion of evolution and dogs, and introgression, here is a new paper I stumbled upon in Molecular Ecology, Detecting introgressive hybridization between free-ranging domestic dogs and wild wolves (Canis lupus) by admixture linkage disequilibrium analysis. Linkage disequilibrium is basically the non-random association of alleles across loci. For example, imagine that you have…

Don’t have time to read all the Science Blogs? Don’t worry, Bora’s put together a literal tapas of selections, part I, part II, part III and part IV.

Alex points me to this Rebecca Goldstein op-ed in The New York Times marking the excommunication of Baruch Spinoza. I am actually reading Goldstein’s biography of Spinoza, Betraying Spinoza: The Renegade Jew Who Gave Us Modernity, and just finished Matthew Stewart’s The Courtier and the Heretic: Leibniz, Spinoza, and the Fate of God in the…

Introgression related papers

I suspect the basic general process of introgression is clear to most of you, though I will get back to it soon. But here are some papers with candidate genes (click “related” for more references): RRM2P4,

SEED on grandmothers

Seed has a piece on the discoveries relating to menopause and its importance to the “Grandmother Hypothesis.” Unlike male decline in fertility menopause is a specific and deliberate sequence of proactive processes by the female body to shut down reproductive capacity. Something like this is almost certainly functionally significant, and anthropological work which seems to…

Below the fold, readers, this is what I mean by doing your technical homework.

Introgression, what’s in a word?

Here is the definition from Wiki: Introgression is a term used in genetics, particularly plant genetics, to describe the movement of a gene from one species into the gene pool of another by backcrossing an interspecific hybrid with one of its parents. Introgression of a transgene from a transgenic plant to a wild relative as…

2 X 2 Design (Adoption + IQ)

Since Jonah posted on the French IQ study profiled in The New York Times Magazine, I thought I’d point to an analysis of the data by a co-thug over at GNXP Classic. Warning, if 2 X 2 ANOVA bores you, prepare to be bored. Otherwise, enjoy. Update: Alex has more analysis.

Limelight on a stupid commenter

Update: It maybe that “idiot commenter” speaks English as a second language , and so was not expressing his skepticism with sufficient nuance for my taste. That being said, this post stands as a warning to those who would waste my time. -God Bless, Razib This commenter starts out by admitting that he didn’t follow…
