Lice have been plaguing humans for eternity. The pests have been found stuck in the hair of mummies dating back thousands of years, and scientists hypothesize that they accompanied humans on their migration out of Africa. Now, archaeologists have uncovered evidence that pre-Columbian peoples were using combs to delouse themselves as far back as 800 years ago. 

A group of researchers discovered combs with microscopic evidence of lice and nits estimated to be 240 to 800 years old in northern Chile. This is the oldest evidence of lice combs found in the Americas, though not in the world (evidence of nits has been found in combs from ancient Egypt [PDF]). The research is published in Chungara, Revista de Antropología Chilena (The Journal of Chilean Anthropology).

The combs have small, close-together teeth made of reeds that would have been used to pick lice and nits out of the hair. The researchers believe they were made to deal with a particularly bad outbreak of the scalp scavengers.

UK Archaeologists Have Found One of the World’s Oldest 'Crayons'

A prehistoric chunk of pigment found near an ancient lake in England may be one of the world's oldest crayons, Colossal reports. The small object made of red ochre was discovered during an archaeological excavation near Lake Flixton, a prehistoric lake that has since become a peat wetland but was once occupied by Mesolithic hunter-gatherers. Though it’s hard to date the crayon itself, it was found in a layer of earth dating back to the 7th millennium BCE, according to a recent study by University of York archaeologists.

Measuring less than an inch long, the piece of pigment is sharpened at one end, and its shape indicates that it was modified by a person and used extensively as a tool, not shaped by nature. The piece "looks exactly like a crayon," study author Andy Needham of the University of York said in a press release.

The fine grooves and striations on the crayon suggest that it was used as a drawing tool, and indicate that it might have been rubbed against a granular surface (like a rock). Other research has found that ochre was collected and used widely by prehistoric hunter-gatherers like the ones who lived near Lake Flixton, bolstering the theory that it was used as a tool.

The researchers also found another, pebble-shaped fragment of red ochre at a nearby site, which was scraped so heavily that it became concave, indicating that it might have been used to extract the pigment as a red powder.

"The pebble and crayon were located in an area already rich in art," Needham said. "It is possible there could have been an artistic use for these objects, perhaps for coloring animal skins or for use in decorative artwork."

11 Inventions That Came Before the Wheel

The wheel is the classic example of early human invention—a quintessential innovation that distinguishes Homo sapiens from all other animals. But in the scope of human history, the wheel is actually a rather young creation. Ancient Mesopotamians in modern-day Iraq became the first people to adopt the wheel only around 5500 years ago, and fairly recent cultures from other parts of the world have managed to make impressive technical accomplishments without wheels at all. (The wheel-less people of Easter Island, for example, transported and erected their towering moai statues less than 1000 years ago.) From booze to the bow and arrow, here are 11 innovations that predate the wheel.

1. BOOZE // 7000 BCE

Some archaeologists are starting to think that the world's first farmers domesticated grains to make beer, not bread. While the extent of alcohol's influence on human civilization is still debated, its antiquity is not. The oldest evidence for booze so far comes from 9000-year-old chemical traces of a fermented cocktail found on a drinking vessel in Jiahu, China.

2. CLOTHING // 150,000 BCE

We're all born naked, but most of us are forced to wear clothes shortly afterwards. Since textiles, leathers, and furs tend to disintegrate over time, scientists have had to get creative in their quest to pinpoint the origin of clothing. The dress above, discovered in Egypt, is at least 5100 years old, but that makes it pretty recent. Clothes actually date back much further: A stone tool from a site in Germany has traces of tanned animal skin, which suggests that humans' Neanderthal cousins were wearing hides 100,000 years ago, and a study from 2011 proposed that the origin of clothes can be traced to the evolution of clothing lice, around 170,000 years ago.

3. JEWELRY // 110,000 BCE

Garments certainly helped humans to compensate for lost body fur and to move into colder climates, but clothes may have also been a cultural invention. As archaeological evidence of jewelry can attest, humans have also been adorning their bodies for decorative purposes for a very long time. Among the oldest surviving pieces of jewelry are 82,000-year-old pierced shells covered in red pigment from a cave in Morocco and a 130,000-year-old eagle-claw necklace found in a Neanderthal cave in Croatia. The above burial, found in Russia at a site called Sunghir, is younger, but still ancient: The man was buried more than 30,000 years ago with an elaborate array of mammoth ivory beads and arm bands, a headband of pierced fox teeth, and a pendant. (Some of the items may once have been sewn onto clothing.)

4. BOATS // 43,000–8000 BCE

Before animal-drawn carts became a preferred mode of transport, there were rafts and boats. The 10,000-year-old Pesse canoe found in the Netherlands is thought to be the world's oldest surviving boat. But humans likely figured out how to navigate the seas for fishing and exploration even earlier. After all, people somehow crossed the seas to populate Australia, Indonesia, and islands in the Pacific at least 45,000 years ago.

5. CALENDARS // 8000 BCE

Long before the gear-wheels of clocks were invented, humans used sophisticated methods to track the passage of time. One group of archaeologists has claimed that the oldest known calendar could be a 10,000-year-old series of 12 pits found in Scotland that appear to mimic the lunar cycle. You can see in the image above how the researchers imagine the system to have worked.

Just as they had to invent ways to track time, so, too, did humans have to figure out how to represent space so that they could navigate their world. Archaeologists still debate the meaning of the earliest rock art, but some of the oldest examples of possible prehistoric maps come from Abauntz Cave in Spain. The 14,000-year-old stone tablets are thought to depict mountains, rivers, and ponds, intersected with routes and hunting game-plans. You can see the top and bottom of one tablet above.

7. COOKING // 1.8 MILLION–500,000 BCE


Sometime after humans learned to control fire, they invented cooking. When you start breaking down meat and plants over an open flame, you don't have to expend as much energy chewing and digesting those foods. A conservative estimate for the rise of cooking would be 500,000 years ago, and according to a recent article in Scientific American, some researchers argue that cooking came about 1.8 million years ago by Homo erectus, a direct ancestor of Homo sapiens. They propose that this development in human evolution is what allowed our brain size to increase.

The darkened passageways inside Germany's Hohle Fels cave get even spookier when you imagine the sounds of flutes echoing through the caverns. This is the archaeological site where the world's oldest musical instruments—43,000-year-old bone flutes made of vulture wing and mammoth tusk—have been found. Want to hear what they might have sounded like? One researcher made a replica of the vulture-wing flute, and NPR has the tune.

9. GLUE // 200,000 BCE

The superglue in your toolbox and Elmer's in your kid's classroom have a long pedigree. About 200,000 years ago, Neanderthals roaming Europe used adhesive tar from birch bark to fix their stone spear tips to handles. Recent experiments suggest this type of glue was complex and difficult to make.

10. POTTERY // 18,000 BCE

Thousands of years before the invention of the wheel, people were making vessels for drinking, eating, and storage by pinching, rolling, or coiling clay into shape and baking it until hard. The oldest crude ceramic vessels come from China and date back 20,000 years. The invention of the wheel allowed for the rise of wheel-thrown pottery. Some even argue that the potter's wheel was probably the first type of wheel ever created.

11. BOW AND ARROW // 7000 BCE

The remains of five bows crafted 9000 years ago were found at the Stone Age settlement of Holmegårds Mose in Denmark. But bows and arrows may have been invented far earlier by savvy hunters who wanted an efficient weapon to kill prey from a distance. Some archaeologists have argued that Sibudu Cave in South Africa contains evidence of 64,000-year-old stone-tipped arrows and bows.
