Here’s a giant ground sloth skeleton, unearthed from the modern state of Missouri. Sloths like this would have stood up to ten feet tall, which was typical of many of the enormous charismatic vertebrates that populated our planet up until the great megafaunal extinction which killed most of them off in the Late Pleistocene, about […]

So here’s a provocative set of evidence from our pre-historic past: hand stencils. Among other questions, they raise a debate about whether the first artists were mostly women. The painted shadows that silhouette the hands you see in this image were frequent subjects of our paleolithic and neolithic ancestors (40,000-1,000 BCE). In 2013, archaeologist Dean
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

Without even googling, I am certain that what you see here has been the subject of a multitude of (probably very expensive but one hopes well-executed) tattoos: this is the famous Dendera zodiac of about 50 BCE, one of the most complete star-charts from the Ancient world. What you can see on it is fantastic.
The Lechuguilla Cave in south-eastern New Mexico (you can see a photo of part of it in the first slide) is the second deepest in the US (at 1,604 feet), and it runs underground for 150 miles. Located in the Carlsbad Caverns National Park, the cave isn’t open to regular visitors because it includes an
On today’s history menu we have a special duo-treat: art, as well as a revised theory about women hunters in early human cultures. And both stories are bound in the spear-throwing devices known as “atlatls”. An atlatl (the name is in the Aztec language Nahuatl because the Spanish saw the Aztecs using it, but
These are the views of Chimney Top, a Tuscarora quartzite outcropping at the end of the North Fork Trail on the similarly named mountain in West Virginia. Pictures don’t do this place justice – besides the immensity of scale that my photographic skills couldn’t capture, its beauty was enhanced by the wind and the solitude.

The Seneca Rocks formation comes from 425 million years ago, when the Tuscarora sandstone formed so much of the mountainous ridge extending through West Virginia. On September 28, 1965, the Seneca Rocks – Spruce Ridge became the first National Recreation Area in a U.S. National Forest. Some of the trees in this area are 200

These two flowers from my neck of the woods both came out along the Appalachian Trail in May: the one to the left was from early this month and is known as a “Rattlesnake Plantain”. The other is blossoming right now at the end of the month and is called a “Pink Lady Slipper.” These

These projectile points were discovered in a 9,000 year-old grave at Wilamaya Patjxa in southern Peru. Archaeologists immediately diagnosed the burial items as part of a hunter’s toolkit and assumed that the person they were buried with was a high-status male from an ancient hunter-gatherer community. However, DNA analysis revealed that the hunter was actually

“The Mushroom Hunters,” a poem by Neil Gaiman, is a feminist paean about science, inspired by history. Some commentary about the history behind the poem: in evolutionary human behavior, much is speculative. “The Mushroom Hunters” draws from many hypotheses made by anthropologists, several of which I have featured stories about. Here are some of them:

This reconstruction of a Homo heidelbergensis (600,000-300,000 years ago) reminds us that we H. sapiens are not the only genus of our kind to have walked the earth, and our Homo ancestors, like us, shared an interesting quality: we lack hair. Of course, we have some hair — our heads and genitals, and many of

This is Humpback Mountain, an incredibly ancient formation dating from the Alleghenian orogany — ie, when the Appalachian Mountains were formed — between 325-260 million years ago. Made up of granite with greenstone, the mountain is part of the Blue Ridge Mountains in Virginia, and you can see why they are called that because of
These are the Shohola Falls, dropping a total of 200 feet in the half-mile course it makes along the Shohola Creek as it drops from Shohola Lake. Located in the Poconos Mountains of eastern Pennsylvania, “Shohola” is an American Indian word that means “meek” or “faint”. This area is part of the Catskill formation and
The origin of mushrooms is ancient — in fact, a 2020 scientific paper reported the discovery of fossilized fungi found in the Democratic Republic of Congo dating from 715 to 810 million years ago! Yet there is much scientists still do not understand about these fruiting bodies of the Earth’s mycelium layer (a network of
