Mini-Book Review — Cochran/Harpending — The 10,000 Year Explosion

by

Cochran G. and Harpending, H., The 10,000 Year Explosion: How Civilization Accelerated Human Evolution, Perseus Books, NY, 2009.

In an earlier cb review of a book on the role of culture and education on American intelligence (Nisbett’s Intelligence and How to Get It:, I mentioned a hypothesis by physicist and iconoclast scholar Gregory Cochran suggesting a genetic basis for Ashkenazi intelligence scores (slightly less than one standard deviation above the American population’s average). Nisbett noted that this slight difference in average IQ translated into massive differences in the distribution of individuals at the very highest IQ levels (140+).

Cochran, and anthropologist Henry Harpending, have now written a fuller discussion of their Ashkenazi hypothesis within the context of a much wider contrarian, and occasionally irreverent, book on the new discoveries in human genetics affecting our understanding of the evolution of modern humans. The authors explicitly reject the convential wisdom that human evolution largely stalled with the emergence of Homo sapiens sapiens as the sole hominid species on the planet.

With new techniques for examining the human genome, it’s possible to give approximate dates on the major recent changes to human physiology triggered by migrations into new environments or the adoption of new economic lifestyles (such as pastoralism or agriculture). Key physiological adaptations such as lactose tolerance, resistance to diabetes or obesity, Vitamin D absorption through skin, malarial protections (subject to recessive genetic disease such as sickle-cell anemia), high-altitude occupation, and the aforementioned Ashkenazis’ IQ, now have associated dates and timetables … and new research promises to nail down the timing and nature of similar genetic changes amongst the world’s populations. The impact of such genetic changes, and associated vulnerabilities, on the human occupation of Europe, North America, and Africa/Asia for the last 50,000 years are the focus of this book.

In contrast to most authors in the biological and social sciences, Cochran and Harpending believe that significant and influential human evolution has occurred in the recent past and that the pace of such evolution continues and even accelerates as selective pressures on modern populations intensify. The larger population pools in turn make it more likely that valuable mutations can spread widely and relatively quickly … often in ways that are completely independent of the X and Y sex chromosomes first used to map human genetic history. For example, Cochran and Harpending suggest that there may well have been an exchange of advantageous genetic mutations (through “introgression”) from Neanderthals to Cro-Magnon/H. sapiens sapiens without any associated impact on the paternal or maternal lines of genetic material associated with our species.

By looking back into post-Neanderthal human prehistory with new genetic data, scholars can track the movement of humans out of Africa and into Asia, Europe, Australia, and the Americas. They can also begin to hypothesize about the role that genetic change played in the relative reproductive success of Upper Paleolithic hunters, the first agricultural communities in Eurasia, and the Indo-Europeans who left their cultural and linguistic imprint on roughly 3 billion of the people in the world today.

Gov. Palin on Health Care Reform

by

From the WSJ: Obama and the Bureaucratization of Health Care: The president’s proposals would give unelected officials life-and-death rationing powers.

Instead of poll-driven “solutions,” let’s talk about real health-care reform: market-oriented, patient-centered, and result-driven. As the Cato Institute’s Michael Cannon and others have argued, such policies include giving all individuals the same tax benefits received by those who get coverage through their employers; providing Medicare recipients with vouchers that allow them to purchase their own coverage; reforming tort laws to potentially save billions each year in wasteful spending; and changing costly state regulations to allow people to buy insurance across state lines. Rather than another top-down government plan, let’s give Americans control over their own health care.
 
Democrats have never seriously considered such ideas, instead rushing through their own controversial proposals. After all, they don’t need Republicans to sign on: Democrats control the House, the Senate and the presidency. But if passed, the Democrats’ proposals will significantly alter a large sector of our economy. They will not improve our health care. They will not save us money. And, despite what the president says, they will not “provide more stability and security to every American.”

Nicely done. A solid critique of Obama and the Democrats which ends with some proposals to do it another way.

(Anybody read anything by this guy, Cannon?)

More like this, please, Gov. Palin.

Healthcare: The Supply Side

by

Here’s a thought experiment. Suppose the year is 1902. Automobiles exist, but they are rare and expensive. The assembly line has not yet been invented, and car manufacturing, such as it is, is done entirely by craft methods.

Now imagine that our politicians decide that every American family, as a matter of national policy, should have its own automobile. (Let’s also stipulate that the trades involved in automobile-building–machining, welding, carpentry, etc–are tightly controlled by guilds.)

What would happen?

Pride in You Tube Voices

by

I’m tired of students who sit in my class for no better reason than that only “students” can remain on their parents’ insurance. I sympathize I, too, want my children covered. But that’s a lousy reason to stay in school. I ran a small business and couldn’t cover my full-time employees or at least cover them well. Hot Air links to a small businesswoman protesting. She argues for opened competition and tort reform. In a longer discussion on television, she explains she’d like catastrophic insurance. Portability, cross-state competition, tort reform, catastrophic insurance options these appear real (direct, market-oriented, constitutional) solutions to real problems. Our system can be improved, but it seems to be righting itself – in the time since I sold my business, our local hmo has opened more options. Why shouldn’t they? We were potential customers.

So, Fox reports – but Not Nearly as Well as Iowahawk.

by

Iowahawk allusion (if you don’t want to entangle yourself in the rest).

Today Fox News discussed “Your Life, Your Choices” , an “end of life” booklet developed by the VA and recommended for use in counseling. The segment appears to have been prompted by Jim Towey’s piece in WSJ, “The Death Book for Veterans.” To counter Towey, the VA’s spokesperson was Tammi Duckworth, VA Assistant Secretary. The exchange was lively, if frustrating.
