Dear BBC: Yes, we are descended from monkeys. And no, evolution and religion are not compatible.

September 26, 2018 • 8:45 am

Yesterday I wrote a bit about the BBC’s new seven-question “Test your knowledge of evolution quiz” (quiz here, my posts here and here), which was (and is) larded with ambiguous questions and wrong answers. They’ve now changed the irrelevant religion question (#7), which originally said, “Evolution and religion are incompatible. True or false?” (the answer was “false,” of course). It now reads “Evolution and religion are not necessarily incompatible. True or false?”. Now that’s a confusing double-negative question, but the answer still touts compatibilism:

Well, we all know that the Beeb is soft on faith (note their “daily affirmation,” or whatever they call the prayer they broadcast each morning), so it’s no surprise. But the question itself palpably does not test one’s knowledge of evolution. It tests whether one is soft on faith. Depending on your definition of “incompatible,” either answer could be right.

Further, they now say that “evolution is not about the origins of life”. First, that’s not necessarily true, since life emerged from nonlife through an evolutionary process, probably involving something like natural selection on combinations of chemicals. But the statement itself implies that if one does consider the origin of life as part of evolution, then evolution is incompatible with religion.  Now why is that? Presumably because evolution is incompatible with the origin story told in Genesis I and II.  If so, then evolution does become incompatible with religion, since Genesis also tells the story of how animals and plants came to be. This is a real confusion on the part of the BBC. At the very least, they have to admit that the story of life—and methodological naturalism—are incompatible with religion.

Further, the Beeb changed the question without any indication that it did so. It was my impression that when a journalist changes an article, the change from the original piece must be indicated on the piece, as an addendum. That’s not done here: more irresponsible (and sneaky) journalism.

At any rate, the question below is still alive, as shown by the tweet below it:

Matthew, Greg and I all think the Beeb got it wrong here. If you’re a strict cladist, you might say that, no, humans did not descend from monkeys; but under the common usage of “monkeys”, yes, our common ancestor would have been recognizable as a monkey.

But the BBC wasn’t thinking of cladism here; it was trying to refute the old creationist trope: “If humans descended from monkeys, why are there still monkeys?”

Here’s a refutation of the BBC’s answer as tweeted by a paleontologist:

 

I’ve enlarged the phylogeny so you can see it.

Finally, one more plaint. The answer to the question, below, even as given by the BBC, is ambiguous. For the answer notes that, if you define progress as “improved abilities to survive and reproduce” under exigent conditions, then yes, evolution does result in progress. It’s only not progressive when you define progress as “getting more complex”, “getting more like humans”, or moving toward some specified goal. The whole question and answer is deeply ambiguous and, like most of the other questions, the BBC should have deep-sixed it.

They missed a good chance to educate people about what evolution is and what the theory says.

The BBC changed the religion/science accommodationism question on its evolution quiz

September 25, 2018 • 1:00 pm

As reader Eric astutely pointed out, the BBC has now changed question #7—the “accommodationism” question—in the evolution quiz I described this morning. It previously read this way:

Now it reads this way:

I’m fairly sure, but not positive, that calling attention to this question by myself or others has led to the change. It’s an improvement for sure, but I emphasize again that this question has no place in a quiz about evolution. It’s a theological or philosophical question that doesn’t test anybody’s knowledge about evolution. What gives, Beeb? You in bed with Templeton?

Further, the “right” answer depends on what you mean by “incompatible”. If you construe “compatibility” as “some people can be both scientists and religious,” then of course they’re compatible. But if you construe it as “compatible in using comparable methods to ascertain what’s true”, then it’s false. My whole book Faith Versus Fact is about this issue.

But the entire quiz is very shoddy, as several readers pointed out. Virtually every question is ambiguous or wonky. I don’t follow BBC science reporting much, but letting this quiz slip by without some vetting by good British evolutionists (e.g. our own Dr. Cobb) is bad journalism.

So it goes.

 

BBC gives a dumb quiz on how much you know about evolution

September 25, 2018 • 8:15 am

Readers Dom and Kevin called my attention to this new quiz on the BBC website that supposedly tests your knowledge of evolution. It was compiled with the help of Dr. Paula Kover, who teaches evolution at the University of Bath.

Click on the screenshot to take the seven-question quiz. I got only 5/7, but that’s because the quiz is badly screwed up!

I won’t reveal six of the science questions (the seventh, below, has nothing to do with science), but I will say that question #5 is deeply screwed up, and the “correct” answer is either wrong or, at best, ambiguous. It could have been phrased better. Matthew and I both think it’s just wrong. (See here for an explanation.)

Matthew and I also objected to question #6. I won’t tell you what it is, but Matthew said it’s ambiguous because “better” is not defined. I agree. If you define “better” as “having increased fitness”, then the answer they give is wrong.

As for question #7, it has NOTHING to do with science, but is simply a sop to religion. And it’s personally insulting because I wrote an entire book supporting what the BBC says is the wrong answer. Here’s the question—guess what they consider the “right” answer:

The BBC could have done a much better job with this quiz since nearly half the questions come with either ambiguous or incorrect answers. So it goes.

 

Bertrand’s paradox

February 19, 2018 • 12:30 pm

Reader Peter sent me this paradox (it’s not really a “paradox” as I understand the meaning of that term, but a result that, like the Monty Hall problem, is deeply counterintuitive). It’s called Bertrand’s Box Paradox after French mathematician Joseph Bertrand, who raised it in an 1889 book on probabilities.

The setup is simple:

There are three boxes:

  1. a box containing two gold coins,
  2. a box containing two silver coins,
  3. a box containing one gold coin and a silver coin.

The ‘paradox’ is in this solution to this question. After choosing a box at random and withdrawing one coin at random, if that happens to be a gold coin, what is the probability that the next coin drawn from the same box will also be a gold coin?

A graphic representation:

I got it after a few minutes of cogitation, but I won’t give you the answer. The only hint is that it’s not what you’d first think, unless you’re a savant. Give your answer and reasoning in the comments, and I’ll chime in showing which answer is right. The link to the paradox at top gives the answer, but try not to look till you’ve given it a go.

It turns out that the probability is identical to that for winning by “switching doors” under the Monty Hall problem with three doors—and for pretty much the same reason.

Quiz: name that arthropod!

Here’s a tw**t sent by Matthew; your job is to guess what this thing is. At least you should be able to get the order! Answer at 12:30 Chicago time.

by Matthew Cobb

JAC: A “holotype” is the one physical specimen of a species whose physical traits were used to describe the species. There’s only one per species, and it’s precious. Nowadays with DNA their usefulness is not as great as it once was, but museums send these things out all the time to people wanting to know whether what they’ve collected is a member of the holotype’s species.

The “MCZ” is Harvard’s Museum of Comparative Zoology, whose laboratory annex is where I did my Ph.D. research.

Test shows that I’m the “Ultimate Christian”. Are you?

July 2, 2017 • 1:15 pm

UPDATE: Several readers report in the comments that no matter how you answer you’ll get 100%. I can’t be arsed to check that, but it seems to be the case. This is DUPLICITY on the part of Christians. But why would they do it? And shame on me for not checking!

________________

This test from Women.com (click on the screenshot) is supposed to determine how good a Christian you are based on questions from the Old and New Testaments. Take it: there are 12 questions. 

 

And what do you know? I ACED IT, getting all the questions right! I am The Ultimate Christian, as evidenced by my results below.  I am washed in the blood of the Lamb, guaranteed to sit at the right hand of God.

Now of course we know about the surveys showing that atheists and agnostics know more about the Bible than do Christians, but somebody apparently forgot that when they designed this test. Also, it wasn’t that long ago when I read the whole Bible from cover to cover. Am I allowed to tell believers that I’ve been pronounced the ultimate Christian?

Can you resist taking this test? Give your results in the comments.

This was the animal track!

Earlier today we reproduced a tw**t by Lisa Buckley (@Lisavipes), which showed a picture of a track she found in British Columbia. We asked you to work out what animal made it.

Many people (like me initially) thought it might be an otter, but the size of the thing – it’s 10 centimetres (= 4″) across – excludes that, as does the simpler fact that otters have five toes… The presence claws show it isn’t a cat, the lack of central pads (and the shape) show it isn’t a bear, and the number of toes (plus the size) show it isn’t a racoon.

So the only answer left is…

Lisa went on to describe a number of times she’d actually encountered wolves, rather than their tracks, doing fieldwork (check out her timeline). She also tw**ted this handy cut-out-and-keep guide to canid footprints, showing why it was deffo a wolf!

Next week Lisa will be curating the @biotweeps account (this rotates between biologists) where, I believe, she’ll be posing some more #NameThatTrack quizzes.
