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.

6. GEOGRAPHIC MAPS // 12,000 BCE

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.

8. MUSICAL INSTRUMENTS // 41,000 BCE

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.

Why Does the Supreme Court Have Nine Justices?

Some facets of the U.S. government—like presidential terms and post offices—were written into the original Constitution after (often lengthy) deliberations by the Founding Fathers. The number of Supreme Court justices was not one of those things.

The document did establish a Supreme Court, and it stated that the president should appoint its judges; it also mentioned that a “Chief Justice shall preside” if the president gets impeached. Since it was left up to Congress to work out the rest of the details, they passed the Judiciary Act of 1789, which outlined an entire court system and declared that the Supreme Court should comprise one chief justice and five associate justices. As History.com explains, they landed on six because the justices would have to preside over federal circuit courts, one of which was located in each state. Traveling wasn’t quick or easy in the horse-and-carriage days, so Congress wanted to minimize each justice’s jurisdiction. They split the courts into three regions, and assigned two justices to each region.

According to Maeva Marcus, director of the Institute for Constitutional History at George Washington University Law School, the even number of justices was a non-issue. “They never even thought about it, because all the judges were Federalists and they didn’t foresee great disagreement,” she told History.com. “Plus, you didn’t always have all six justices appearing at the Supreme Court for health and travel reasons.”

Over the next 80 years, the number of Supreme Court justices would fluctuate for two reasons: the addition of federal circuit courts, and presidents’ partisan motives. John Adams and his Federalist Congress reduced the number to five with the Judiciary Act of 1801, which they hoped would prevent Democratic-Republican Thomas Jefferson from getting to fill a seat after he took office that year. By the following year, Jefferson’s Congress had passed another judicial act that returned the number of justices to six, and they upped it to seven after forming another circuit court in 1807.

The nation grew significantly during the early 19th century, and Congress finally added two new circuit courts—and with them, two new Supreme Court seats—during Andrew Jackson’s presidential tenure in 1837. Republican Abraham Lincoln then briefly increased the number of justices to 10 in order to add another abolitionist vote, but Congress shrunk it to seven in 1866 to keep Andrew Johnson from filling seats with Democrats. As soon as Republican Ulysses S. Grant succeeded Johnson, Congress set the number back to nine, where it’s remained ever since.

In 1911, Congress did away with circuit courts altogether, so the number of Supreme Court justices stopped being contingent upon their expansion (though each justice does still oversee a region to help with occasional tasks). As for presidents shifting the number to serve their own goals, it’s now looked down upon as “packing the court.” When Franklin D. Roosevelt tried to increase it to 15 in the 1930s to push his New Deal through the Supreme Court, the Senate opposed the bill by a whopping 70 to 20 votes.

In short, the depth of the Supreme Court’s bench changed a lot in America’s early years not only because the country was expanding, but also because the federal government was still testing out its system of checks and balances. And though presidents do still appoint justices based on their own political party, we’ve gotten used to the idea that the Supreme Court is, at least ideologically, supposed to be unbiased. If Congress and the president kept up the habit of adding and subtracting justices at will, it would tarnish this ideal.

“If Congress increases the size of the Supreme Court for transparently partisan political reasons, it would cement the idea the justices are little more than politicians in robes, and that the court is little more than an additional—and very powerful—arm through which partisan political power can be exercised,” Steve Vladeck, a professor at the University of Texas School of Law, wrote for NBC News. “Indeed, that Congress has not revisited the size of the court in 150 years is a powerful testament to just how ingrained the norm of nine has become—and how concerned different political constituencies have been at different times about preserving the court’s power.”
