A few days ago I did a post featuring a fossil of a creature called Archaeopteryx, famed for having traits both bird- and dinosaur- like: it filled in a gap in the evolutionary record. The photo you see here is of the paleo-biologist Neil Shubin with a model of a creature whose fossils he found. […]

Historians are frequently enchanted by things discarded as useless by the general public. But I think anyone interested in evolution would find the study of non-gene coding DNA fascinating, including the scientist featured here. This is Susumu Ohno, one of the United States’ foremost geneticists and evolutionary biologists, and he came up with the term

“The Persistence of Memory” is one of artist Salvador Dali’s most recognizable paintings. The surrealist style is perfectly adapted to depicting the ways our minds preserve our memories — they are suggestive, dreamlike, warpable. For however imperfect or relativistic our memories might be, we owe them for much of our sense of identity.How we humans

Charles Darwin’s idea of Natural Selection as the key driver of evolution has been demonstrated many times over. However, in the century and a half since his lifetime, scientists have added onto his theories as various scientific discoveries have been made. Perhaps no one has reframed the picture of Darwinian evolution as much as the

It’s almost Halloween, dear readers, so you’ll be able to suss out my theme for this week without a hitch. On that note, I cannot believe that I have not yet done a post on Elizabeth Bathory, aka “the Blood Countess”.So here’s her story: born into an aristocratic Hungarian family in 1560, Elizabeth Bathory was

I am perfectly delighted to bring you this post about Vampire-babies and witches in Ancient Rome. The skull you see here is that of a 10-ish-year-old child, recently excavated in a 5th-century CE Italian graveyard known as “La Necropoli dei Bambini” (the Cemetery of the Babies). Notice the large rock jammed into its jaw —

Many cultures have produced mythologies of the frightening undead. But in the modern American imagination, our ideas about Vampires can largely be traced to the early 1700’s. In Eastern Europe, tales of the deceased who somehow caused the deaths of their living neighbors began to arise.The first documented episode came out of the Serbian village

What was it about Eastern Europe in the 1700s that brought about so many stories of Vampires? Some scholars note that Western European countries like Britain might have enjoyed these legends because they could make people feel civilized — those “eastern places” were rural, Catholic, superstitious, and backward in the minds of nationalist Brits.However, there

And what would a week’s worth of Eastern European Vampire posts be without a story on Vlad “the Impaler” Dracula? I should especially include Vlad because Boston College, where I got my Ph.D., had not one but *two* Dracula specialists when I was studying there.In American pop culture, the Vampire repertoire takes its cue from

I don’t know why the central character in this Ancient Greek image is smiling: she is getting stabbed. Maybe because the artist was taking sides with the playwright Aeschylus, who thought Clytemestra deserved to die? Athens in the 5th c BCE was a civilization whose male citizens prided themselves on having a democracy with a

This is a satirical comic from the magazine _Life_ from 1888. In it, the moral crusader Anthony Comstock is shown accosting an artist painting a woman bathing. “Don’t you suppose I can imagine what is under the water?”, proclaims Comstock.It is a fitting caption for the man who gave his name to the indecency law

“There never was a greater crime against humanity,” wrote the famed Byzantine scholar Sir Steven Runciman, “than the Fourth Crusade.” And although unfortunately untold numbers of atrocities could easily compete for this claim, certainly the sack of the glorious city of Constantinople marks a horrifyingly violent chapter in the history of Christianity.The city had been

In the early 20th century, science was trendy. Unfortunately, so was bigotry, and the eugenics movement took advantage of the scientific-sounding language of genetics to promote the idea that certain types of people (pretty much white, native-born, able-bodied, and Protestant) needed to propagate for the greater good of humanity. Enter the “Fitter Family Contests” held

The global situation right now is dominated by discussion of COVID-19, as well as the Herculean attempts to create a vaccine for the disease. And as reports of the Phase III trials start to come in, we can look at this photo — a scientist’s laboratory from the early 20th century, cluttered and filthy. Rotting

“The good thing about science,” writes astronomy popularizer Neil deGrasse Tyson, “is that it’s true whether you believe in it or not.” One could also state that the opposite can be the case — merely wishful thinking will not alter the rules of the material world. Or the biological one. But this is not what

Medieval violent bunnies onstage for this post, which makes me laugh no matter what.We do not expect these furry (mostly) vegetarian creatures to be shown inciting bloodshed, or picking on poor unarmored monks (slide two), or mauling naked men when they are sleeping (slide three), or viciously destroying King Arthur’s entourage (the Rabbit of Caerbannog,

Medieval warfare less often squared equivalent armies on the ground against each other, and more often entailed raiding and sieges. In a pre-gunpowder arena, a castle’s walls and well armed keep could withstand months of an invader’s armies. The offensive side used a variety of tactics to get their opponents to surrender, including throwing stones

The two pictures shown here accompanied two of the most important “aha!” moments in history. The first is “Photo 51,” taken under the laboratory research of Rosalind Franklin. It shows an X-ray diffraction pattern of DNA, and Franklin, Watson, and Crick used it to figure out the molecular structure of life itself.The second is a

I am going to do a magic trick for you — take a look at the two photos here: one is a 15th century painting of a Locust, and the other is Ernie Chambers, the longest-serving state senator of Nebraska (46 years and counting). And my hocus pocus will be to show how these two

The Scientific Revolution that developed in Europe did not always lead to the embracing of rationality. This engraving by William Hogarth from 1751 is a case in point. You see in this image a grand display of the dissection of a corpse at the hands of professional anatomists. Yet even though the endeavour might have
