Hamza Tzortzis is playing gotcha with Lawrence Krauss now

After that debate between Tzortzis and Lawrence Krauss that was overshadowed by the disgraceful anti-egalitarian exhibition of Muslim misogyny, iERA is now trying a new tactic: they’re releasing tiny snippets of the debate that they believe they can spin into anti-Krauss sentiment. Here’s a perfect example, Krauss’s reply to a question about the morality of incest.

The audience gasped when Krauss said it’s not clear to him that incest is wrong, and then he went on to argue that there are biological and societal reasons why incest is not a good idea, but that he’d be willing to listen to rational arguments for sexual and emotional interactions between siblings, for instance…not that he’d encourage such behavior. It’s a nuanced and complicated reply in too short a time, but otherwise, he’s not wrong.

But you know what Tzortzis is thinking: this is a perfect clip to play to the dogmatic mob, his people, who don’t do complicated and nuanced, and don’t care about rational arguments, only absolute dictates.

I’d add two other arguments that might sink in.

One is that religions also rationalize incest. Here’s the Protestant Christian example:

Since Eve was made from one of Adam’s ribs [Genesis 2:21-22], she would have been a clone of Adam and, had there been any genetic mutation in Adam, this would have been reproduced in Eve and expressed in their offspring. However, we may reasonably conclude that there were no mutations, and the very first commandment given to them was “to be fruitful and multiply” [Genesis 1:28]. However, the business at the tree of the knowledge of good and evil took place long before there were any children.

The account then continues where God confronted the guilty pair at the tree, but they did not confess their guilt or plead for forgiveness [Genesis 3:1-13]. God then cursed the serpent, imposed reproductive difficulties upon Eve and “cursed the ground for [Adam’s] sake” [Genesis 3:17]. From that moment, everything that Adam – and mankind since – ate had grown in the cursed ground. Cell by living cell, Adam began to very slowly change from his initial state of eternal perfection to mortal imperfection, and he finally died at the age of 930 years [Genesis 5:5]. Nevertheless, Adam and Eve’s immediate offspring would have been very close to physical perfection while brother-sister marriages were the only unions possible! Further, according to the genealogies given in Scripture, pre-flood longevity was about the same as that for Adam, so families were very large compared to those of today. Brother-sister unions were not only unavoidable, but they undoubtedly became traditional and expected.

Catholics make a similar argument.

Incest was not a problem for the immediate descendants of Adam and Eve. It became a problem when the deterioration of the gene pool meant that there was an increased likelihood that the offspring of the unions of near relatives would inherit physical or mental problems. Adam’s immediate descendants inherited perfect or nearly perfect genes, so the unions of near relatives were not a problem. Besides, near relatives were the only people who existed.

Muslims, too.

it is a known fact that legislation differs from one Shari’ah to another, while the principles and beliefs remain the same in all of them. So, making of portraits was allowed in the Shari’ah of Sulayman (peace be upon him) but is prohibited in our Shari’ah. Similarly, making prostration of salutation was permitted in the Shari’ah of Yusuf (peace be upon him) but is illegal in ours. Also, war booty was prohibited for nations before us but it is completely legal for us. The Qiblah of people before us used to be towards Bayt Al-Maqdis, but for us it is towards Ka’bah. In a similar way, marriage between brothers and sisters was permitted in the Shari’ah of Adam (peace be upon him) as opposed to those that came afterwards. The following is a clarification on the issue by Haafidh Ibn Katheer, who said:

Allaah allowed Adam (peace be upon him) to marry his daughters to his sons for necessity. Every couple used to have a boy and a girl. Hence, he married the girl of one couple to the boy of another. This is said by Suddi regarding what has been narrated by Abu Maalik and Abu Salih, from Ibn ‘Abbas, by Murrah from Ibn Mas‘ood and by other companions of the Prophet (peace be upon him) that Adam did not have (in his grandchildren) a baby boy unless it was accompanied by a girl, so he married the male of a couple to the female of another, and the female of a couple to the male of another

So apparently their absolute moral prohibition against incest isn’t quite so absolute after all. A good Muslim can fuck his sister if Allah tells him to.

But the other example I’d give is current, and it’s done all the time. Ever looked at a purebred Arabian horse’s pedigree? It’s an incestuous nightmare, and it’s encouraged — it’s even regarded as a good thing to reinforce good stock with a moderate amount of inbreeding.

Here’s an example of a horse pedigree. Notice what’s going on?

horsepedigree

Look at Pie’s Joseph, for instance. He is the product of a breeding between Wood’s Jay and Wood’s Jay’s granddaughter, Wood’s Chili.

Pie’s Joseph was then bred with his own niece, Pie’s Lady I, and they had a daughter, Pie’s Lady II. Pie’s Joseph was than bred to his own daughter to produce a son, Blue Joe, who is also his grandson.

Let’s not even get into cows and pigeons. Here’s a quick glimpse at the sordid sex life of Favorite:

Are you squicked out yet? You shouldn’t be. This stuff is going on on farms all over the world. The biological prohibition isn’t quite as strong as you might think — if you want extremes of a phenotype, as you might in agriculture, trying to achieve selective homozygosity for specific traits might actually give you an advantage.

We tend to not want that kind of result in human crosses…although, if you think about it, an unscrupulous nation could embark on a breeding program for athletic ability that would benefit from a multi-generation pattern of incest…

But this all highlights a common problem: get into a debate with fanatics and ideologues like the iERA mob, and they will actually hold it against you if you actually consider the complexities of reality. We like both complexity and reality; how can you argue with someone who comes in with a bias that what you regard as virtues are sinful, and demands that the universe fit itself to their false simplicities?

A quote from Ed Abbey, who died 24 years ago today

The geologic approach is certainly primary and fundamental, underlying the attitude and outlook that best support all others, including the insights of poetry and the wisdom of religion. Just as the earth itself forms the indispensable ground for the only kind of life we know, providing the sole sustenance of our minds and bodies, so does empirical truth constitute the foundation of higher truths. (If there is such a thing as higher truth.)

It seems to me that Keats was wrong when he asked, rhetorically, “Do not all charms fly … at the mere touch of cold philosophy?” The word “philosophy” standing, in his day, for what we now call “physical science.” But Keats was wrong, I say, because there is more charm in one “mere” fact, confirmed by test and observation, linked to other facts through coherent theory into a rational system, than in a whole brainful of fancy and fantasy. I see more poetry in a chunk of quartzite than in a make-believe wood nymph, more beauty in the revelations of a verifiable intellectual construction than in whole misty empires of obsolete mythology.

The moral I labor toward is that a landscape as splendid as that of the Colorado Plateau can best be understood and given human significance by poets who have their feet planted in concrete — concrete data — and by scientists whose heads and hearts have not lost the capacity for wonder. Any good poet, in our age at least, must begin with the scientific view of the world; and any scientist worth listening to must be something of a poet, must possess the ability to communicate to the rest of us his sense of love and wonder at what his work discovers.

What I taught today: molecular biology of bat wings

Hard to believe, I know, but this class actually hangs together and has a plan. A while back, we talked about the whole cis vs. trans debate, and on Monday we went through another prolonged exercise in epistatic analysis in which the students wondered why we don’t just do genetic engineering and sequence analysis to figure out how things work, so today we reviewed a primary research paper by Chris Cretekos (pdf) that teased apart the role of one regulatory element to one gene, Prx1, in modifying the length of limbs. It’s a cool paper, you should read it. It’s kind of hard to replicate the teaching experience in a blog post, though, because what I did most of the hour was ask questions and coax the students into explaining methods and figures and charts.

I’m afraid that what you’re going to have to do is apply for admission to UMM, register for classes, and take one of my upper level courses. I always have students read papers direct from the scientific literature, and then I torture them with questions until they extract meaning from them. It’s fun!

Although…it would also be cool to have a scientific-paper reading and analysis session at a conference, now wouldn’t it? Especially if it could be done over beer.

What I taught today: farewell to flies (for a while)

A good portion of what I’ve been teaching so far uses Drosophila as a model system — it’s the baseline for modern molecular genetics. Unfortunately, it’s also a really weird animal: highly derived, specialized for rapid, robust development, and as we’ve learned more about it, it seems it has been layering on more and more levels of control of patterning. The ancestral system of establishing the body plan was far simpler, and evolution has worked in its clumsy, chance-driven way to pile up and repurpose molecular patterning mechanisms to reinforce the reliability of development. So I promised the students that this would be the last day I talk about insects for a while…we’ll switch to vertebrates so they can get a better picture of a simpler, primitive system. What we’ll see is many familiar genes from flies, used in some different (but related!) ways in vertebrates.

But today I continued the theme of epistatic interactions from last week. Previously, we’d talked about gap genes — genes that were expressed in a handful of broad stripes in the early embryo, and which were regulated in part by the even broader gradient of bicoid expression. The next level of the hierarchy are the pair rule genes, which are expressed in alternating stripes — 7 pairs of stripes for 14 segments.

First point: notice that we are seeing a hierarchy, a descending pattern of regulatory control, and that the outcome of the hierarchy is increasing complexity. One gene, bicoid sets up a gradient that allows cells to sense position by reading the concentration of the gene; the next step leverages that gradient to create multiple broad domains; and the pair rule genes read concentrations of gap genes and uses the boundaries between them to set up even more, smaller and more precise domains of stripes that establish the animal’s segments.

This is epigenesis made obvious. The 14 stripes of the pair rule genes are not present in the oocyte; they emerge via patterns of interactions between cells and genes. The information present in the embryo, as measured by the precise and reproducible arrays of cells expressing specific genes, increases over time.

So part of the story is hierarchy, where a complex pattern at one stage is dependent on its antecedents. But another part of the story is peer interaction. Cells are inheriting potentials that are established by a cascading sequence of regulatory events, but in addition, genes at the same approximate level of the hierarchy are repressing and activating each other. We can tease those interactions apart by fairly straightforward experiments in which we knock out individual pair rule genes and ask what the effect of the loss has on other pair rule genes. I led the students through a series of epistatic experiments which started out fairly easy. Knock out a pair rule gene that is expressed in odd numbered parasegments, for instance, and it’s complement, the pair rule gene expressed in even parasegments, expands its expression pattern to fill all segments. Sometimes.

Some of the experiments reveal simple relationships: hairy suppresses runt, and runt suppresses hairy. That makes sense. They have mutually exclusive domains, so it’s no surprise that they exclude each other. But then we looked at other pair rule genes which are expressed in patterns slightly out of phase from the hairy/runt pair, and there the relationships start getting complex. Genes like fushi tarazu are downstream from all the others, and their effects are straightforward (their loss doesn’t disrupt the other pair rule genes), but genes like even-skipped have much messier relationships, and the class was stumped to explain the results we get with that deletion.

So I asked them to come up with other experiments to tease apart these interactions. I was somewhat amused: when I think along those lines, I come up with more genetic crosses and analyses of expression patterns — I think about regulatory logic and inferring rules from modifications of the pattern. Students nowadays…they’re so much more direct. They want to go straight to the molecular biology, taking apart the genes, identifying control elements, building reporter constructs to see gene-by-gene effects. I felt so old-fashioned. But we also had to talk about the difficulty of those kinds of experiments, and that often the genetic approach is better for building a general hypothesis that can be fruitfully tested with the molecular approach.

Then we stopped — we’ll come back to flies later, and start looking at some specific subsets of developmental programs. Next, though, we’re going to take a big step backward and look at early events in vertebrates and progress through that phylum until we see how they build segments. I’m hoping the students will see the similarities and differences.

Sadly, it’s International Women’s Day

It’s that day when we’re supposed to celebrate the accomplishment’s of women. I say “sadly,” because unfortunately there are way too many people out there who would rather sneer at and diminish women’s status in the world.

Case in point: on twitter, I ran across this lovely tweet from one of those repugnant slymepitters.

On #IWD remembered the nearly 0 wimmin – Nobels in science, highbrow art, chess GMs, great standups, but 100s of pop-culture hos #ftbullies

`

Yes. Let’s remember those women.

Let’s remember Lise Meitner, Hilde Mangold, Chien-Shiung Wu, Rosalind Franklin, and Jocelyn Bell — who were all well-qualified (men won the prizes for work equivalent to what they did, instead) to win a Nobel but didn’t get one.

Rather than 0 women, perhaps we should remember Marie Curie and Maria Goeppert Mayer, who won Nobels in physics; Irène Joliot-Curie, Dorothy Crowfoot Hodgkin, and Ada E. Yonath in chemistry; Barbara McClintock, Carol W. Greider, Christiane Nüsslein-Volhard, Elizabeth H. Blackburn, Françoise Barré-Sinoussi, Gertrude B. Elion, Gerty Cori, Linda B. Buck, Rita Levi-Montalcini, and Rosalyn Yalow, in physiology or medicine. Clearly women are not intrinsically incapable of scientific work at the highest levels. Of those whose work I’m familiar with in detail, I have to tell you that McClintock blows me away with the stunning brilliance of her abstract reasoning — I know of no other male scientist whose work is at all comparable (that of course is a matter of taste!)

The relatively lower frequency of women recieving Nobels is not something any man should take pride in; what it really indicates is that we’ve been shortchanging half the human population, depriving them of opportunities to excel. Wait — we’ve been doing worse than shortchanging women; we’ve been depriving all of humanity of the potential in those minds. This pattern of discrimination against women has hurt us all.

Let’s not forget also all the people, men and women alike, deprived of opportunities because of their race or class — deprived by the kind of endemic bigotry that would, for instance, denigrate an entire group of people as “pop-culture hos”. And it’s not just science — it was good of our petty MRA to remind us that we’ve also lost their contributions to art and theater and games.

That’s what I think of everytime some bigot crows about the absence of some group of people from some field of endeavor — it’s a reminder of all that we’ve lost to selfish stupidity.

My university in the news!

Now if only it were good news. It seems we’re the victim of bureaucratic excess.

College administrators have found an interesting new way to strike it rich: quitting their jobs. Upon leaving his role as executive vice president of NYU for a job with Citigroup in 2006, Jacob J. Lew (the current Secretary of the Treasury) took a $685,000 bonus from the university. Harold S. Koplewicz, an executive at the NYU Medical Center, got a $1.2 million severance after choosing to leave voluntarily. Given that NYU’s tuition and fees are among the highest in the nation, we’re curious how students who took out hundreds of thousands of dollars in loans feel about their money going towards generous benefits and severance packages for administrators.

At least NYU is a private institution, so tax dollars are not spent to cover its inflated costs. As the New York Times notes, public universities are just as guilty of letting a bloated and inefficient administration drive up tuition costs. The University of Minnesota employs 19,000 administrative officials employees, and administrative personnel account for 24 percent of its total payroll, compared with only 20 percent in 2001. At Purdue, the number of administrative employees grew by 54 percent in the last decade.

Overall, the number of administrators hired by colleges and universities increased 50 percent faster than the number of instructors hired between 2001 and 2011, according to the U.S. Department of Education.

We’ve felt the pain down here in the trenches, too. Our core biology curriculum was disrupted a bit by the reluctance of our administration to hire replacement faculty — they saved a few pennies by bringing in temporary faculty as replacements and deferring filling tenure track lines. The replacements were good people, but when you’ve got students coming up through a curriculum pipeline, you really want stability and continuity at the base.

The good news, though, is that the blockages have been uncorked and we’re finally expanding our biology faculty from 8 to 9 — a big boost at a small college.

You know who else was a great painter? Hitler.

Sorry for the excessive hyperbole, but I had to counter the sniveling sycophancy in this Fox News puff piece.

They’re impressed that it took “only a month” to teach him to paint like that? It shows. He’s going to go down in history as a great artist? Judging by what is shown in that clip, this is a retired guy with a nice hobby. That’s about it. Good for him — at least he’s not ripping the hearts out of virgins and kicking puppies for a hobby like Dick Cheney — but come on, American Pravda, let’s not lay it on quite so thickly.

I think I’ve just been persuaded that MOOCs suck

I’m convinced. Physioproffe is right: MOOCs are a great big boondoggle. It wasn’t PP’s words (true as they are) that persuaded me, though — it’s that Thomas Friedman has endorsed them, in a godawful column complete with helpful discussion with his driver from the airport.

Just consider this claim:

We demand that plumbers and kindergarten teachers be certified to do what they do, but there is no requirement that college professors know how to teach. No more. The world of MOOCs is creating a competition that will force every professor to improve his or her pedagogy or face an online competitor.

Holy crap. Right now I’m in ‘competition’ with skilled colleagues who were selected for their position on the basis of their teaching skill — I’m evaluated in comparison with my peers. I’ve seen these MOOC-style lectures, and please please please, I would love to be assessed against some person whose interactions with students are entirely through a glass screen, in a format that favors linear lecturing, and considers email a marvelous way to communicate outside of class.

This is what Friedman considers an increase in competition for college teachers? I see a slackening and a reduction of standards…and what the administrators and mouth-breathing ignoramuses like Friedman see is a way to outsource and reduce the costs of the expensive part of an education…the part that is also the only real education component of the process.
