A Devonian hexapod

It always seems to be the case that there are gaps in the fossil record just where things get interesting — probably with good reason, that forms in transition will be relatively rare. One such gap is the period where insects first emerge and begin to conquer the terrestrial world, a period called the arthropod gap, between 385 and 325 million years ago. Here’s a new specimen from that relatively barren stretch of time, Strudiella devonica.


a, Photograph of the part. b, Reconstruction of general habitus. Scale bar, 1 mm. White arrows indicate legs visible on part. abd, abdomen; ant, antenna; h, head; md, mandible.

It’s a classic insect: a body divided into three regions (head, thorax, abdomen), six legs, a fairly general set of omnivorous mouthparts. It lacks wings, but the small size suggests it may be in a nymphal stage (also, the genitals at the tip of the abdomen didn’t make it), so that may not mean much.

Jared Diamond spanks Mitt Romney

In an obvious ploy to appear erudite and well-read, Mitt Romney recently cited Jared Diamond to support his ill-informed opinions on culture. It’s really a bad idea to misrepresent a living scientist, because they tend to come back and expose you as a dishonest fraud.

It is not true that my book “Guns, Germs and Steel,” as Mr. Romney described it in a speech in Jerusalem, “basically says the physical characteristics of the land account for the differences in the success of the people that live there. There is iron ore on the land and so forth.”

That is so different from what my book actually says that I have to doubt whether Mr. Romney read it. My focus was mostly on biological features, like plant and animal species, and among physical characteristics, the ones I mentioned were continents’ sizes and shapes and relative isolation. I said nothing about iron ore, which is so widespread that its distribution has had little effect on the different successes of different peoples. (As I learned this week, Mr. Romney also mischaracterized my book in his memoir, “No Apology: Believe in America.”)

Oops. Didn’t read the book, huh? I’ve had a few student papers like that.

The real stinger is in the conclusion.

Mitt Romney may become our next president. Will he continue to espouse one-factor explanations for multicausal problems, and fail to understand history and the modern world? If so, he will preside over a declining nation squandering its advantages of location and history.

Stalker!

It’s like she’s following me everywhere. Stephanie has a summary of upcoming conferences, and I seem to be at all of them.

This year I have resolved to NOT write a whole new talk for every event I go to, because it was killing me*, so she’s probably going to skip my sessions at least a few times.

*Also, somehow, over the last few years I’ve ended up developing and teaching a brand new course every year, and this coming term is no exception (at least it’s a core course with a long history, but I still am new to teaching it). There’s nothing quite like having to compose three or four new lectures every week for my job and, oh, by the way, do another one for fun for the weekend.

Comedy is dangerous

Abdi Jeylani Malaq Marshale must have been an awesomely brave person. He lived in Somalia, he was a comedian, he made fun of Islamists, and he worked to dissuade young people from joining the insurgency.

So someone shot and killed him.

And it’s not just comedians!

So far this year, at least one Somali journalist has been targeted and killed each month.

The Jack D. Ripper School of Reproductive Biology

So I got in this odd twitter argument — arguing against a point so stupid, so against reason and biology, that I didn’t bother to bring it up here. The source of this argument was an MRA site, AVoiceForMen (home to the odious JohnTheOther and Paul Elam, if you recall), and the discussion was about the relative biological cost of sex. The standard biological view is that sex is cheap for men, and expensive for women; men produce numerous small, cheap gametes, most of which are disposable and thrown away, and do not have to bear the cost of pregnancy and lactation, and can often dodge the bother of child-rearing altogether, while women produce very few large, metabolically expensive gametes, and by necessity bear all the costs of pregnancy and lactation. And of course, in our culture, they also get saddled with most of the work of raising children.

The MRA argument was a perverse inversion of reality. It argued that men are the costly sex, because they have to ejaculate their precious sperm during intercourse, while the ladies just lie there and have fun.

We have this attitude toward hookup culture because we are convinced that male sexuality has no value. Not even no value, we think male sexuality has negative value.

Men sow their seed hither and yon; women guard their vaginas like Fort Knox.

But is this true?

Let’s think about it logically. With each act of sex a male ejaculates semen into the female. This is an investment of physical resources that takes time for the male to replenish. So male animals are limited in how often they can have reproductively viable sex. Female animals, on the other hand, are not. The sex act has zero cost to them.

Now, the reason this obvious truth is invisible to us is because we lump in the cost of carrying young with the cost of sex. Yes, carrying young is high female investment but the sex act itself is higher male investment.

It really is the ‘precious bodily fluids’ argument presented seriously. Men are the ones who should guard their essence, while women shouldn’t care.

Why? Because, quite simply, his sperm is in limited supply. He wants to prioritize delivery of sperm to a.) high quality females and b.) less mated females.

I don’t even…

Men spontaneously produce approximately 100,000,000 sperm cells per day. We make them whether we have sex or not. They have a limited shelf life; there is good evidence that mature internally stored sperm begin to decline in quality after about a week.

There is no sperm shortage at all.

Women, on the other hand, produce one gamete per month. If you want to make the “limited supply” argument, and an economic claim that a scarce commodity will be marketed much, much more carefully, it ought to be applied not to the menz but to the womenz. And also note that the only way the author can make her (yes, her) claim at all is by intentionally neglecting all the costs of pregnancy.

There are a couple of commenters there arguing with this patently bogus rationalization — it would be hard not to, it’s so absurd — but other commenters are just unbelievably gullible.

Epicness sauteed in awesomesauce!

As long as you ignore the fact that it’s, like, wrong.

And if you’re fond of word salad, how about this?

Best written post on Female’s Hypergamy & their polyandrous relationships, Female sexuality is pretty much distorted, When sexual revolution was forced on to become the social and cultural norm, WOMYN in majority never repelled it or rejected it, they gladly accepted it and have made it their daily routine (To fuck more men) their so called pair bonding in ancestral time was “Forced” pair bonding but with new innovations like “NO FAULT” divorce and incentives, cash prizes and child custody they are now pretty busy shaking up more dicks after breaking up with their “now” ex’s.

But overall MGTOW are catching up with that, Maybe PUA are mindless drones but even though male sexuality is also becoming more like female sexuality, Even more males are now calling out their inner “ape” or “gorilla” because of this new CULTURAL and SOCIAL Norm of sexual revolution, but as i said Women were the starter of all this insanity and they are now reaping what they sow.

I’m sorry, but I feel queasy at the thought of linking to AVoiceForMen (officially declared a hate site by the SPLC!), but here’s another article that effectively shreds their idiocy. Read that instead.

Why I am an atheist – QB

I know I am an atheist because when the dive team found my friend’s 8 year old daughter after being underwater for almost 15 minutes, my first reaction was NOT to plead and bargain with some godly being, but rather to hope that the science was on our side. While I drove to the hospital, I counted minutes. I calculated the water temperature, hoping that the natural springs and recent rain fall had made the lake cold enough to preserve brain function. I recalled every article, every journal, and every medical book I had ever read about the survival rate for children in drowning accidents.They say there are no atheists in foxholes, but in the panicked, 25 minute, 90 mph drive to the hospital, I realized I thought of everything…except to pray.
