Daily Data Dump – Tuesday

By Razib Khan | August 10, 2010 2:46 pm

Genetic Components and Cultural Differences: The social sensitivity hypothesis. The frequency of genes and “memes” change in very different ways. As I have long observed while memes can be passed from only one parent, genes are constricted in sexual reproduction to being inherited in part from both parents. How the two may relate (e.g., lactase persistence), and the causal direction of that relation, is going to be interesting to flesh out in the next generation.

Demographic Disparities Found Among Children With Frequent Ear Infections. Sometimes when I see stuff like this I wonder, “is this another article about how colored people bite?” Nope. “frequent ear infections plague white children and children living below the poverty level more than children of other racial or ethnic backrounds or income levels.”


Virginia May Nab Serial Rapist Through Blood Relative DNA. Wow, things move fast. Looks like someone has introduced legislation to allow the FBI to do this sort of thing too.

Population admixture, biological invasions and the balance between local adaptation and inbreeding depression. Open access and accessible.

Pets Vital to Human Evolution : Discovery News. Humans are the technological species, but much of our technology is biological in the form of our domesticates. But physical and biological technology are fundamentally different in some ways, because biology has more proximate (neurological) and ultimate (evolutionary) agency.

    The thing in Virginia is a perfect example of when I’m not sure what I want. The idea that the government can scan DNA profiles is a little unnerving, however this man needs to be hung up by his toenails. Ug, the UCLA member in me very seldom gets along with my inner Charles Bronson

    The second I saw this outrageous The Top 12 Reasons To Burn A Quran On 9/11 article my first thought was this blog’s commentators must have an opportunity to read this! http://hubpages.com/hub/The-12-Top-Reasons-To-Burn-A-Quran-On-911

    Regarding,
    “Virginia May Nab Serial Rapist Through Blood Relative DNA”

    I worry about those whom believe themselves to be benevolent and seek to find others for things other than violent crimes.

    Not that I think there’s likely anything I can do about it.

    (But it’s part of the reason I’ve been hesitant to get a 23andMe test, despite being curious from a genetic genealogy point-of-view. Although obviously, it’s not just about me. And I can’t control what my relatives do. So regardless of my choices, it may be futile.)

    I wonder if ear infections are tied to the quality of home. After all the poor will tend to live in cheaper and older homes more likely to be infected with mold and mildew. That in turn will increase allergy problems and lead to more ear infections. I say this as the parent of two children with a lot of ear infections due to mold and mildew. I don’t know what we’d have done had we not been able to afford allergy treatments, tubes in the ears, and air filters.
