The evidence for evolution

November 11, 2014 • 7:28 am

[The internet is down at the Kirksville Holiday Inn. The only other time this has happened to me was when I was in Russia. What this means is that posting may be light today. Fortunately Greg prepared a post on a recent talk he gave about evolution, which is below. JAC]

by Greg Mayer

Jerry has posted a couple of times in the last week or so on the “creationist shenanigans” at Georgia Southern University, where a professor is apparently openly proselytizing for his religion in classes on the history of science. One of the items the professor has produced is an online document titled “No evidence for evolution“. It’s actually a rather sad document– and not just because it’s a typically dishonest creationist exercise in quote-mining, which would have us believe that Jerry Coyne, George Gaylord Simpson, Jeff Levinton, Niles Eldredge, and Steve Gould, among others, can all be rallied to the cause of creationism. Nor is it because he mixes in quotes from the likes of  Michael Denton and Francis Hitching, as though they had any authority at all. Nor is it even because of his schizophrenic view of Gould and Eldredge, who on the one hand he wields in support of creationism, but on the other he attacks (through quotes) because (gasp!) they are evolutionary paleontologists. No, it’s sad because it’s all so old. Other creationists did this decades ago– and, frankly, better. The quotes are almost all old ones– from the 1980’s and earlier (the latest quote I noted was 1997– the page is dated 2002). The reason it’s so sad is that not only does this guy know nothing about biology or paleontology, he’s not even a very good creationist– he apparently hasn’t kept up with developments in his own “discipline”!

Just a day or two after Jerry posted, my colleague Chris Noto informed me that a talk I had given at Darwin Day celebrations earlier this year was now available online. Entitled “The Evidence for Evolution”, it seemed like a happy coincidence, and so I share it with you here. (Note that the Parasaurolophus and sauropod behind me seem quite interested, the latter even bending his neck above and around me so he can read my notes on the podium! There was a human audience too, although, as usual, until a late attendee arrived, no one wanted to sit in the front seats.)

The talk was given at the Dinosaur Discovery Museum in Kenosha, Wisconsin, as part of their Darwin Day events last February. It was based on the chapter I wrote for The Princeton Guide to Evolution, edited by my friend and colleague Jon Losos, which was officially published right about the time I gave the talk. The talk is about descent with modification per se, and not on the mechanisms of evolution (except insofar as the observation of current evolutionary changes allows us to see such mechanisms directly), and the main topics were the fossil record; transitional forms; comparative morphology, embryology and genetics; biogeography; and evolution in action. I would particularly draw attention to the example of observed speciation in Spartina in England (about 30:44). It’s an example of allopolyloid speciation (a new species arises by hybdidization with increase in the number of chromosome sets), which is common in plants (though not animals), and is expected to occur very rapidly, but it’s nice to have a case where humans observed the speciation event start to finish (1829-1892).

(The camera battery went dead for a bit, so there’s about 5 minutes of the biogeography section missing; the dead space was edited out with a “wave”– you’ll notice it.)

Finally, a reason to have “belief in belief”

November 10, 2014 • 12:23 pm

This is the best reason I’ve seen yet for promoting religion even if you don’t accept it yourself. It stops people pissing on the walls! Or so say Ranjani Iyer Mohanty in a piece in the The Atlantic, “Only God can stop public urination.”

If you’ve been to India, and I have (many times), you can’t help but notice the prevalance of public defecation and urination, for private toilets aren’t ubiquitous (almost nonexistent in villages), and public excretion has become a noxious custom, even in the large cities. How do you stop it? As Mohanty describes, you put up tiles or murals depicting the gods on walls customarily used for male urination.

I suspect it won’t work.  If you gotta go, you gotta go, so you’ll just move your outdoor activities to another place.  But here are some photos of the urination-preventing devices:

Mohanty has other suggestions:

My daughter, a firm believer in national integration, has suggested that these god tiles also include Muslim, Christian, and Sikh iconography. After all, if there’s one thing Indians have in common, it’s their god-fearing—or at least god-respecting—nature (pollsreveal that roughly 90 percent of Indians view religion as an important part of their lives). I wonder what would happen if I placed a few god tiles around my daughter’s room; after all, messiness cannot be next to godliness.

In fact, the concept has already expanded to several faiths. In documenting how tiled Hindu, Muslim, Christian, and Sikh gods arrived in Mumbai’s streets (they replaced or supplemented written messages ranging from the polite “please do not sully the wall” to the more aggressive “son of an ass, don’t pee here”), the Indian photographer Amit Madheshiya recently marveled at the “harmonious existence for the gods” in such “cluttered and messy spaces”—especially in a predominantly Hindu country that “is often irreversibly divided along the coordinates of religion.”

Unfortunately, panaceas are rarely perfect. The other day, as I was leaving my neighborhood, I spotted a man on the same road urinating against those same walls. I was shocked. Who could be so bold as to disregard the presence of all those gods? And then it dawned on me: He might be an atheist.

Yes, we have here something rare: a completely novel critique of atheism!

More of the “it’s not religion; it’s anything else” nonsense from the UK

November 10, 2014 • 11:18 am
The loudest Western defenders of Islam and the biggest critics of “Islamophobia” are now the newspapers and radio stations in the UK, especially the Guardian and the Independent. But the BBC plays a role too. Here’s a BBC report with a three-minute must-watch video showing a 13-year-old Syrian boy (“Abbu Hattad,” now in Turkey) expressing his desire to become a jihadi and join ISIS. (Click on the screenshot to go to the piece, which is also here).
Screen shot 2014-11-10 at 6.37.38 AM
Besides noting the horror of such a young child brainwashed into wanting to “behead infidels”, and claiming that “Allah told us to fight for the next life—for Paradise,” we see his mother saying how happy she’d be if her son died as a martyr for ISIS.
To what does the BBC commentator attribute the child’s motivations, and that of other children bent on becoming jihadis? He concludes:
The Syrian children who join these militant groups grew up in war, and much of their motivation must come from that experience. Their formative years have been blackened by hatred, their mindset altered, their childhood stolen. The innocence of a generation is being destroyed—no longer seen as children, but as tools of war.
Notably absent is any mention of religion, except from the boy himself. Nope, it’s just “war:. And even though it’s a war in which kids like Abu explicitly ascribe their motivations to religion and to the Muslim promise of paradise, the BBC wants to stay miles away from that one. It’s the “anything-but-religion” psychology that permeates the British media.  It’s despicable. We can’t begin to effectively defeat the enemy under we understand what drives him. ~

Intersectional faith

November 10, 2014 • 10:00 am

This cartoon, from reader Pliny the in Between and posted at his site Pictoral Theology, is the answer to all those liberal apologists who tell us that “all faiths are at bottom really the same.” (That’s stupid on the face of it!). I like the liberal characterization of theistic evolution at top left.

Why is free speech waning?

November 10, 2014 • 8:47 am

Since the 1960s, when I was engaged in various forms of liberal political activism, I’ve seen a waning of the support for free speech, so that now speech that offends people (erroneously lumped as “hate speech”) is under question.  The UN, of course, is contantly beleaguered by Muslim countries to make “defamation” an international crime, but much of the pressure also comes from college campuses in the U.S. and U.K. In fact, in our student newspaper last week, one student, offended by a Halloween costume of another (granted, a costume expressing a noxious national stereotype) called for help from the administration to suppress that kind of thing because, as he said, “Words hurt.”

“Words hurt” is the mantra of the new suppress-free-speech movement. And yes, words can hurt feelings, but so what? They also make people think. My view has always been that of the U.S. government itself: that speech cannot be suppressed so long as it doesn’t try to incite immediate violence.  If someone wants to wear a Halloween costume stereotyping Jews as hook-nosed, money-grubbing killers of Christ, more power to them. I will combat that with the best weapon I have against that kind of “speech”: other speech.

But, as we know, things are changing. And I don’t know why. The change is described in an article by John O’Sullivan in the Wall Street Journal:No offense: the new threats to free speech.” It’s ironic that in matters like free speech and the right to criticize religions like Islam, we leftists must sometimes make common cause with conservatives, and find support not in the Guardian or the New York Times, but in the Wall Street Journal or the National Review. (Note: that does  not mean that we adhere to conservative political policies!)

At any rate, O’Sullivan describes the anti-free-speech trend, but doesn’t analyze the reasons for it very deeply. Here are a few excerpts, and it’s a shame that we find such defenses of free speech mainly in right-wing venues:

Hearing criticisms of your own convictions and learning the beliefs of others are training for life in a multifaith society. Preventing open debate means that all believers, including atheists, remain in the prison of unconsidered opinion. The right to be offended, which is the other side of free speech, is therefore a genuine right. True belief and honest doubt are both impossible without it.

It isn’t just some Muslims who want the false comfort of censoring disagreeable opinions. Far from it. Gays, Christians, feminists, patriots, foreign despots, ethnic activists—or organizations claiming to speak for them—are among the many groups seeking relief from the criticism of others through the courts, the legislatures and the public square.

England’s libel laws—long a scandalous system for enabling the rich to suppress their scandals—now have imitations in Europe and the U.S. In May 2014, the European Court of Justice created “the right to be forgotten,” enabling those with ugly pasts—a fraudster, a failed politician, an anti-Muslim bigot perhaps—to delete their crimes, misdemeanors and embarrassments from Internet records so that search engines cannot find them.

Here we get a sense—and I think O’Sullivan’s right—that a some of the pressure to restrict free speech comes from religious people (especially Muslims and Catholics), “ethnic activists” (those who don’t want their ethnicity or nationality, or certain national policies, criticized), and from certain quarters of feminism that decry any criticism as misogyny and bullying. But if this is indeed the case—and I suspect there are other causes as well—why is this happening now?  After all, the rectitude of treating women, minorities, and those of other ethnicities as moral equals has been a theme in Western society for at least five decades. Yes, some of the pressure comes from other parts of the world, like the Middle East, but that doesn’t explain why Western society is becoming less supportive of free speech.

Nor can it be explained by the rise of postmodernism. After all, that movement sees no “truth” privileged over any other, ergo postmodernism should never support restrictions on speech.

More from O’Sullivan:

This slow erosion of freedom of expression has come about in ways both social and legal. Before the 1960s, arguments for censorship tended to focus on sexual morality, pornography and obscenity. The censors themselves were usually depicted as benighted moral conservatives—priggish maiden aunts. Freedom of political speech, however, was regarded as sacrosanct by all. As legal restraints on obscenity fell away, however, freedom of political speech began to come under attack from a different kind of censor—college administrators, ethnic-grievance groups, gay and feminist advocates.

Could it be that now that Baby Boomers—of which I am one—are in positions of power (politicians, college administrators, and so on), our youthful fights for diversity have been transformed into misguided attempts to maintain diversity by suppressing criticism that we see as harming it?  That’s of course, is a mistake; as O’Sullivan says, “The right to be offended, which is the other side of free speech, is therefore a genuine right. True belief and honest doubt are both impossible without it.”

He continues:

The new censors advanced such arguments as that “free speech can never be an excuse for racism.” These arguments are essentially exercises both in begging the question and in confusing it. While the principle of free speech cannot justify racism any more than it can disprove racism, it is the only principle that can allow us to judge whether or not particular speech is racist. Thus the censor’s argument should be reversed: “Accusations of racism can never be an excuse for prohibiting free speech.”

Meanwhile, the narrowly legal grounds for restricting speech changed, too. Since the 18th century, the basic legal justifications for restricting political speech and publication were direct incitement to harm, national security, maintaining public order, libel, etc. Content wasn’t supposed to be considered (though it was sometimes smuggled in under other headings).

Today, content is increasingly the explicit justification for restricting speech. The argument used, especially in colleges, is that “words hurt.” Thus, universities, parliaments, courts and various international bodies intervene promiscuously to restrict hurtful or offensive speech—with the results described above. In the new climate, hurtful speech is much more likely to be political speech than obscene speech.

There it is: “words hurt”— the very phrase that appeared in our student newspaper yesterday. (The student who wrote in was offended by another student dressed up in a Halloween costume as a Mexican narco. That is offensive but shouldn’t be prohibited.)

The three paragraphs above comprise a decent analysis of the history of speech restriction, but don’t get at the reasons for increasing restriction. Surely 9/11 and the actions of extremist Muslims are one reason (we have to shut up about Islam or we’ll be threatened or killed), which plays on misguided (and bigoted) sentiments that Muslims must be treated with kid gloves compared to other groups—a double standard for behavior.

But that doesn’t explain it all. It’s palpably clear that free speech as a principle of democratic society is on the way out. Not completely, for it’s written into the American Constitution, but even Canada and the UK are restricting its exercise, and European countries like France, Germany, and the Netherlands have criminalized public denial of the Holocaust. (I find this execrable: it is through the response to Holocaust denial that I in fact learned a lot about the evidence for the Holocaust.)

In the end, I’m baffled, except in my conclusion Muslim threats and terrorism are responsible for restrictions of speech that criticizes Islam (and, by extension, religion as a whole). I’m also at a loss to explain why, in my own country, one of the foci for the anti-free-speech movement is the college campus. Surely college campuses should, if anything, be a hotbed for free speech, for that is where you learn to think about and assess your own values and beliefs. But the collusion of administrators and students is eroding that freedom, too.

I suspect readers will have their own theories about what has happened to free speech in the last 20 years or so, and I’m eager to hear your theories, which are yours.

Readers’ wildlife photos

November 10, 2014 • 6:19 am

Reader John Crisp sent a bunch of lovely photos he took in the Masai Mara, Kenya, Africa, including many felids.  John’s information is indented.

A wildebeest for lunch:

The lion and lioness together are in the midst of a long mating session. We watched them for 20 minutes and they mated four times. They will maintain that pace for a week, averaging about every fifteen minutes. This activity weakens the male and makes him more vulnerable to a takeover of the pride by another male, who will then kill any young cubs in the pride. So only the strongest males get to leave progeny and in the end they too will be driven from the pride once they are too old. So, to paraphrase the cliché about politics, all leonine careers end in failure.

Female leopards and cheetahs raise their cubs alone. Leopards do pretty well, though their cubs can be vulnerable to lions and hyenas. Cheetahs have the hardest time and are under some threat even in the Masai Mara. Since their only asset is speed, they are the only one of the big cats to hunt in daylight, but they are, as our scout rather unkindly said, “cowardly”, which means that they can be chased away from their kill by any of the other cats and by hyenas. The one that photographed in twilight must have been hungry, because soon after this she took off after after a bush hare, but missed in the semi-darkness.
