Dog and cat breeders, pigeon fanciers, racehorse breeders, and others whose livelihoods depend on their trying to do better than nature at the Darwinian game often offer anecdotes about breeding failures. They thought they might get a faster horse, but they got a skittish one instead; they thought they were getting a good bird dog, but the dog would panic at the shot of a gun.
Breeders know genetics carry a lot of traits, and trying to select for one is difficult. One may amplify a bad trait in addition to the desired trait.
In one classic paper that more critics of Darwin should read, researchers discovered that instead of getting better egg production, they got mean chickens that damaged production of the entire flock.
One of my favorite papers in evolutionary biology, which I have mentioned here before, is this:
Muir, W.M., and D.L. Liggett, 1995a. Group selection for adaptation to multiple-hen cages: selection program and responses. Poultry Sci. 74: s1:101
It outlines the group selection effects observed when trying to breed chickens for increased egg production in multiple-hen cage environments. In short, selecting individual chickens for increased productivity in a group environment didn’t select for increased productivity. Instead, it selected for mean chickens. The result was an overall reduction in productivity. Only by selecting at the group level was productivity increased.
The topic is a worthy one for discussion in economics courses, especially with regard to incentives for certain behaviors.
There is this caution: Adam notes that Enron annually fired the “bottom 10%” as a matter of policy, trying to encourage everyone else to work harder, trying to reward productive people, trying to prune deadwood from the corporate vine. At one point, some divisions of GE Corp. would purge the bottom 25%. That’s even more intensive selective pressures, for evil as well as good.
And when legislators try to purge education of bad teachers? Can they possibly hope to get anything but mean chickens? Economists indict our reliance on standardized tests of students.
If Science no longer has the ear of society, if it cannot put forth the results of its findings, good or bad, favorable to me or not, without being shouted down by those who have both reason and the resources to suppress those findings, then we have lost far more than the future benefits of scientific and technological contributions to society. Contributions that, over the last two hundred years, have permitted the human species to achieve a standard of living far beyond the wildest imaginings of pre-Industrial Revolution humanity.
We have lost the essence of Liberty.

SMU has about an hour of tape of a speech Dr. King delivered at SMU in 1966. While the speech is not particularly noteworthy, it’s a good example of King’s rhetoric of the time. You can put it on your iPod.
It’s a real period piece — King in a southern, formerly segregated town, so soon after the Voting Rights Act. Real history, real people. Very interesting.
SMU has activities running all week long. Things change in 40 years.
(Check out the socks and ties of the men on stage — and where are the women?)

Tony Campolo is an evangelical Christian, a sociology professor and preacher who for the past 15 years or so has been a thorn in the side of political conservatives and other evangelicals, for taking generally more liberal stands, against poverty, for tolerance in culture and politics, and so on. His trademark sermon is an upbeat call to action and one of the more plagiarized works in Christendom, “It’s Friday, but Sunday’s Coming” (listen to it here).
Rev. Tony Campolo; photo from Berean Research.
Since he’s so close to the mainstream of American political thought, Campolo is marginalized by many of the more conservative evangelists in the U.S. Campolo is not a frequent guest on the Trinity Broadcast Network, on Pat Robertson’s “700 Club,” nor on the white, nominally-Christian, low-budget knock-off of “Sabado Gigante!,” “Praise the Lord” (with purple hair and everything).
Campolo came closest to real national fame when he counseled President Bill Clinton on moral and spiritual issues during the Lewinsky scandal.
His opposite-editorial piece in the Philadelphia Inquirer yesterday, “The real danger in Darwin is not evolution, but racism,” is out of character for Campolo as a non-conservative evangelistic thinker — far from what most Christians expect from Campolo either from the pulpit or in the college classroom. The piece looks as though it was lifted wholesale from Jerry Falwell or D. James Kennedy, showing little familiarity with the science or history of evolution, and repeating canards that careful Christians shouldn’t repeat.
Campolo’s piece is inaccurate in several places, and grossly misleading where it’s not just wrong. He pulls out several old creationist hoaxes, cites junk science as if it were golden, and generally gets the issue exactly wrong.
Evolution science is a block to racism. It has always stood against racism, in the science that undergirds the theory and in its applications by those scientists and policy makers who were not racists prior to their discovery of evolution theory. Darwin himself was anti-racist. One of the chief reasons the theory has been so despised throughout the American south is its scientific basis for saying whites and blacks are so closely related. This history should not be ignored, or distorted.
At the time of this writing, it appears the site for the Martin Luther King, Jr., Center has been hacked — an illustration of the need for citizens to stand up for civil rights and human decency, still.
Creationism is a doctrine to which I, like most Christians, do not subscribe. It springs from a wrong understanding of the Word of God. And anybody who thinks he or she is going to impose his own personal narrow, vain, idolatrous doctrine on the children of this state as they sit helpless in their tenth grade Biology classrooms will have a fight on his hands. Again.

Tangled Up in Blue Guy hosts the current Carnival of the Godless. I don’t usually note this carnival, partly because evangelizing atheism is not my goal; but that’s not the goal of the carnival, either. TUIB Guy is an occasional reader and commenter here; his hosting job takes an interesting view of carnival hosting. Carnival of the Godless frequently features informative and useful posts. In this one, especially if you are involved in science education, or you know a Ron Paul supporter, you should read this post, from the Atheist Ethicist.
Great material for the classroom:
Four Stone Hearth constantly provides material that I wish I had used the last time I taught that particular topic. Four Stone Hearth #32 at Testimony of the Spade features several posts on neolithic children. This material probably would resonate well with elementary and middle school student. This is a roadmap to how you can make the section on Native Americans and early migration to America come alive for younger students.
Yes, I know: It’s a test of human evolution, and evolution passed. When I put “proof” in the headline, more people will give it the attention it deserves.
Teachers, you can register for the teacher information, and download this video for free use in your classroom presentations. I recommend it highly. (These rights are rather fuzzy about blogs, so I have not put the video here.)
This has become part of Ken Miller’s presentation to teachers — it was part of his lecture at Southern Methodist University on November 16, and I suspect it was a key part of his presentation to the Conference for the Advancement of Science Teaching (CAST) in Austin, on November 17 — a conference sponsored by the Science Teachers Association of Texas (STAT) and at which attendance would probably get Texas state education officials fired.*

* Chris Comer was a featured speaker at this meeting. It’s likely the poobahs at the Texas Education Agency didn’t figure out that any meeting of science teachers and scientists in Texas would feature evolution; one may hope that they don’t figure that out, if they continue to campaign against evolution and other science.

In addition to Amazon, the book is available for free download at the National Academy of Science’s site. It’s a great backgrounder for anyone interested in learning “what scientists say” about evolution and creationism, from our nation’s oldest and most trusted society of science advisors (Lincoln called on NAS for advice, and wise policy makers still do).
Students learn history best when it affects them directly, or when they can see the stuff close up. The Legacies Dallas History Conferences focus on history in and around Dallas, Texas. This is prime material for Texas and Dallas history, economics and government classes.
If you’re teaching at a high school or middle school in the Dallas area, print this off for every social studies and English teacher at your school, and pass it out to them Tuesday (or Monday if you’re open then).
Many of the conference presentations roll down that alley of a topic most Texas students need more of, the events around World War II. One session dives into Vietnam, one goes back to the Civil War, and World War I is remembered.
Bob Reitz, the public historian who curates the amazing Jack Harbin Museum of Scout History at Dallas’s Camp Wisdom, alerted me to the conference with a plug to his colleague’s presentation. Anita Mills-Barry will present her paper, “Homefront Scouting During World War II: Participation by Boy Scouts and Girl Scouts in the Civilian Effort in Dallas County.”

LYNDON JOHNSON: It’s all of us, who must overcome the crippling legacy of bigotry and injustice. And we shall overcome.
BILL MOYERS: As he finished, Congress stood and thunderous applause shook the chamber. Johnson would soon sign into law the Voting Rights Act of 1965 and black people were no longer second class citizens. Martin Luther King had marched and preached and witnessed for this day. Countless ordinary people had put their bodies on the line for it, been berated, bullied and beaten, only to rise, organize and struggle on, against the dogs and guns, the bias and burning crosses. Take nothing from them; their courage is their legacy. But take nothing from the president who once had seen the light but dimly, as through a dark glass — and now did the right thing. Lyndon Johnson threw the full weight of his office on the side of justice. Of course the movement had come first, watered by the blood of so many, championed bravely now by the preacher turned prophet who would himself soon be martyred. But there is no inevitability to history, someone has to seize and turn it. With these words at the right moment — “we shall overcome” — Lyndon Johnson transcended race and color, and history, too — reminding us that a president matters, and so do we.
Use of DDT would have started earlier, the article says, but for lack of money.
So, participants in the defense of wise environmental policy and Rachel Carson, against the scurrilous charges of junk science purveyors, should take note:
There is no ban on use of DDT against mosquitoes, in a serious, controlled program of integrated pest management.
No environmentalist is to blame for the lack of DDT use in Uganda (and probably elsewhere). As with anti-malaria programs worldwide, lack of funding or lack of organization generally is the reason for any lack of action against malaria.

My blog, Millard Fillmore's Bathtub, is a continuing experiment to test how to use blogs to improve and speed up learning processes for students, perhaps by making some of the courses actually interesting. It is a blog for teachers, to see if we can use blogs. It is for people interested in social studies and social studies education, to see if we can learn to get it right. It's a blog for science fans, to promote good science and good science policy. It's a blog for people interested in good government and how to achieve it.
