Yesterday I did a post about the “boring billion”: a period of Earth’s history when very little changed. Today I offer the exact opposite, which is the most exciting two minutes in all of existence. And those in fact were the first two minutes of everything, at the start of the Big Bang. We […]
No, this isn’t what you think it is, readers: I know it *looks* like a penis, but really it’s not. Rather, what you see is a 16th-century woodcut illustration of the dissected genitals of a woman. Er, if that’s not obvious to you, don’t worry. Commissioned for Andreus Vesalius’s famous _De humani corporis fabrica_

Here are four different species of finches from the Galapagos Islands. Although they look similar, their differences include their beaks — each one takes advantage of a different type of seed. Natural selection shaped the trajectory of these birds’ appearance, and one of the scientists who first figured out how this worked passed away yesterday

The root system you see here isn’t just part of the plant: it’s joined by fungi, making it a mycorrhiza — a symbiosis of plant and fungi. Most plants rely on mycorrhizae — the fungi elements give the roots better access to precious nutrients like phosphorous and water, and the plant bits give the fungus

TIL that 30 million years ago a species of mound-building termites evolved with next-level techniques that we humans could learn from in order to deal with our environmental challenges. These are the Macrotermes, and what makes them particularly special is the very ancient relationship they co-created with the fungus Termitomyces. Neither survives without the

I love how scientific technologies are helping us understand the earliest millennia of human history ever better. This drawing, for instance, features an artistic re-creation of skull fragments dated in 2017 that have helped to overturn our understanding of human evolution. Basic questions, such as “how long have Homo Sapiens been around?” And “where

This is a book that of which I am not a fan. _The Alphabet Versus the Goddess_, by Leonard Shlain, argues that the development of the written word allowed patriarchy to flourish. Sigh. Shlain’s background was in surgery, and the premise of his thesis is rooted in physical claims. “Alphabet literacy,” he asserts, gains

This extraordinary scene from a 348-long muslin painting called “Panorama of the Monumental Grandeur of the Mississippi Valley” was done by an American artist named John J. Egan in 1850. Looking carefully at the details, you can see that white Americans are using their black slaves to open up an American Indian burial mound. The

Malaria is, like COVID, a largely preventable death: so long as the patient gets the right treatment at the right time. Many still do not have access to good medical care. For instance, in 2019, 409,000 people in Africa — mostly babies and toddlers — died of this disease. But malaria is not a

This is a drawing of the prehistoric species Plesiosaurus, discovered by the paleontologist Mary Anning in 1823. Anning was a working-class, uneducated person who became one of England’s premier fossil scholars, but struggled her whole life — financially and professionally — because of her gender and class. Anning grew up on the southern coast

This lovely creature was a Dinogorgon, one of many types of animals known as “Gorgonopsia,” the apex predators in the Permian Period. When I learned about how boss these creatures were, the nine-year-old paleontologist in me felt cheated because of all the front stage play that dinosaurs get. But these animals were amazing and thrived
This is a picture of Hvalsey Church, a Norse ruin from a settlement in Greenland that was abandoned in the 1400s. Scientists and historians have recently amended their ideas about what caused the collapse of this culture. In the late 900s, some Vikings from Iceland migrated to Greenland, setting up small communities that lasted
This is a set of bone sewing needles found in the Cave of Courbet near Toulouse, France, dating to around 13,000 years ago. Trace the history of the sewing needle and you will trace one of the key technologies that enabled Homo sapiens to migrate around the planet, and to outlast our closest human relatives,

The Ancient Greeks were right to have the story of how Prometheus brought fire to the human race front-and-center in their mythology. Fire is an amazing thing — most vertebrates flee from it when it happens in the natural world. But we humans learned to control it, and that revolutionized our existence. The control of

In the US, Mother’s Day is this Sunday, so I thought it appropriate to introduce this fine specimen, representative of what many Paleo-anthropologists consider the earliest known mother of all hominids (including us Homo sapiens). This is the Ardipithecus ramidus, and she lived about 4.4 million years ago in what is now modern Ethiopia. Her

As per my usual holiday tradition, I wrote an historically themed Christmas carol! This one is to the tune of “I Saw Three Ships”, and it’s called “I saw three hominids”. I had been lacking a tune about prehistory! I saw three hominids come inNeanderthal, Den’snovianGenus Homo all are kinHurray for evolution I spoke with

This is John Tenniel’s famous 1871 illustration of the poem “Jabberwocky,” the most famous nonsense poem in the English language. Linguists have long remarked upon the genius of the way Lewis Carroll’s poem explores questions about language and meaning. But Tenniel’s illustration better shows the new Victorian awareness of Charles Darwin’s ideas about evolution and

The origins of human history keeps getting pushed further back in time, as a recent analysis of a wooden structure in Africa dating back almost a half a million years demonstrates. For reference, anthropologists now date the emergence of homo sapiens to about 200,000 years ago (although some argue for 300,000). The wooden structure discovered

Creationists frequently bring up the Piltdown Man to support their idea that scientists deliberately lie about human evolution. True, the Piltdown Man was a famous fake (built by *one* “scientist”) – a supposedly missing link between humans and apes. However, it was actually the scientific community that proved the bones to be a forgery.
