I adore Early Modern Science! Through no fault of their own — since genes hadn’t been discovered but everyone in Europe knew about horrible parasitic body worms — some biologists thought of sex and propagation in very different ways than we do now. For instance, _preformationists_ thought that there were very small people inside either […]

Sometimes Medieval art gets weirder the more you look at it. For instance, take these scenes of an animal fleeing from a hunter: the creature isn’t just turning his head back — he is actually biting off his testicles to throw them to his pursuer. Medieval people thought that beavers regularly did this (I know:

In the background you are hearing the 15th-century English Christmas “Boar’s-Head Carol,” and looking at a closeup of a boar hunt from the month of December in the lavishly illustrated _Tres Riches Heures du Duc de Berry_ (circa 1440). In my home state of Pennsylvania, deer rifle season is heralded by hunters as an important

Two years ago, researchers published findings concerning DNA samples taken from the Early Medieval York Gospels. Manuscripts from this era are extremely rare: it was written around 990 and lavishly illustrated. By taking a simple eraser, scholars used a technique called “eZooMS,” which allowed them to sample DNA from the pages without damaging them. A

Parents of kids besotted by the Disney channel might roll their eyes at how successfully the movies have mesmerized their children. But the practice of telling fanciful stories featuring youths who must navigate magic and non-human creatures is quite old. The genre owes its name, _Les Contes des Fees_, “Fairy Tales” to one Madame d’Aulnoy,

Flu season is upon us, and I still need to get my flu shot. If the unfortunate happens and I do get sick, _The Distaff Gospels_ has some words of healing advice for me.Readers of yesterday’s post will recall that the _Distaff Gospels_ is a book of women’s lore from the 15th century, and has

In the Middle Ages, the lens of Christianity permeated the world view to a degree unimaginable today. We can see this with the descriptions and illustrations of animals like the lion, whom many authors considered king of the beasts. And, since they thought that God/Christ ruled over the universe, lions were compared symbolically to the
This little beauty is an artist’s rendition of a Placoderm – an extinct fish from close to 500 million years ago which had a significant feature that has played out into the lives of all humans today. Early fishes from this geological period had jaws, and evolutionary scientists have recognized jawed vertebrate fish as the

The COVID outbreaks in American meat-packing warehouses have recently cast attention to the frankly horrifying working conditions in these plants. Like coal-mining and cesspool-cleaning, the practice of animal slaughter and butchery has a long history being considered an undesirable profession — it is one that most of society benefits from, even as the general population

Pesky flies torment this poor dog in a Medieval manuscript from the early 1300s. Then and now, we have seen these insect vermin as an annoyance. In the Middle Ages, however, flies were associated with something far more sinister — demons.So it was that in the fourteenth century, a poor woman called Ermine de Reims

This sculpture by Paul Lancz from 2014 is one of the many public works of art always on display in the city of Montreal. Entitled “La Tendresse/ Tenderness,” it captures a ubiquitous display of affection between mother and child. This physical gesture of a mother kissing her baby has been a hallmark of affection uniting

Along a particularly rocky portion of the Tuscarora Trail in Perry County, Pennsylvania, is situated a 3,037-acre wildlife sanctuary established by Florence W. Erdman in memory of her mother. The F.J. Reineman Wildlife Sanctuary dates from 1966, and the trust establishing this land gave it to Dickinson College in Carlisle, Pennsylvania, which is just near

Since the year 2000, the Audubon Society has been involved with the site shown here called Hawk Watch. Located at Waggoner’s Gap along the Kittatinny Ridge just north of the town Carlisle in south-central Pennsylvania, Hawk Watch has a legacy of being a major corridor for thousands of hawks, eagles, and falcons who traverse across

Here come two points about human evolution – the first is one that I imagine is not surprising to you, but the second may be, and might make you wince.First, the animal in this photo is not an ancestor of us Homo Sapiens. We did not evolve from apes but share a common progenitor that

When does the story of Alice actually intersect with rabbits? In the case of evolutionary history — and a failed attempt at biological warfare in Australia.I can think of nothing that demonstrates the process of biological evolution more clearly than viruses. Because their genomes are so small, their genetic mutation rates produce a rapid effect.

This picture is neither a coffee stain nor a bad tattoo, but rather a fossil from one of the most important places that evolutionary scientists study the emergence of complex life: the fossils of Burgess Shale in British Columbia.Burgess Shale fossils date from the period of the Cambrian Explosion (525-505 million years ago), when “all

Evolution brings a sense of humility like nothing else can. Ladies and gentlemen, may I introduce you to our ancestors? Featured on the first slide is “Kimberella,” probably the oldest of the “protostome” fossils, dating 255 million years ago – from before the pre-Cambrian explosion.“Aha,” you might be thinking. “That doesn’t look like even the

“The difference in mind between man and the higher animals, great as it is, is one of degree and not of kind,” wrote Charles Darwin, in his famous _The Descent of Man_ in 1871. And evolutionary biologists still agree. So then what makes the mental capacities of Homo Sapiens and other hominid apes so different?Two

Wanna know the difference between this kid and a chimpanzee? So do evolutionary biologists . . . And with the use of genetic studies, scientists recently have figured out two additional ways that we Homo Sapiens differ from our common primate chimp ancestors from six to eight million years ago. They have to do with

By the Early Modern period in England, many people associated witches with their accompanying animals called “familars.” At the bottom of this woodcut you can see “Boy” (also “Boye”) the dog and alleged familiar of the military leader Prince Rupert of the Rhine, who died with his master in battle in 1644.The familiars of 17th-century
