If you’re interested in fashion or someone who has been in the military or scouting, perhaps you may have taken a liking to khaki clothing. Or maybe you’ve come to associate the color with explorers, expeditions, and safaris in Kenya and elsewhere.

What is Khaki Anyway?

First, let us define what is khaki. Khaki is a color that has sometimes been described as a shade of gray, a shade of green, or a shade of brown. Of all of these, “shade of brown” is probably the most accurate. In fact, historically, the color khaki is defined to be a shade of tan, and tan is a kind of light brown. This refers to the color itself, but as we will discover later, the word has evolved to have a wider meaning.

What Does Khaki Mean?

Khaki is a loanword from West Asian languages. Specifically, it comes from Urdu and in that language, it means “dust-colored”. The Urdu word itself is believed to have come from a Persian (or Farsi) word meaning “dust”.

The association with dust is probably not surprising. After all, khaki clothes have been associated with outdoor exploration and militaries for generations. Why is the color so popular in these kinds of activities? One reason is camouflage. You see, the color became popular among the militaries of countries with large desert areas. Having khaki clothes allowed them to blend in easily with predominantly brown desert environments. Over time, this military association also trickled down into other outdoor activities such as safaris and hiking. This makes sense considering they involve very similar conditions.

Is Khaki Considered Green?

It depends on who you ask. Strictly speaking, when referring to the color, the term “khaki” refers to specific shades of brown. That means that “khaki” in this sense cannot be used to describe shades of green.

However, as with all things, styles and definitions evolve. Today, khaki is not only used to refer to a specific color but also a style of clothing. You may have heard of khaki pants, khaki shirts, khaki shorts, khaki socks, and so on. You may have also noticed that they aren’t always brownish. Instead, they may be a shade of green. Khaki is now applied to a style of clothing, one that has a wider definition, color-wise. Even shades of green have been referred to as “khaki” as long as they are meant to fit outdoor activities and fashion.

Is Khaki Considered Brown?

As mentioned earlier, khaki the color is considered to be a shade of tan. That means, if you are talking about the color khaki itself, then yes it is considered to be brown. Indeed, the term “khaki” itself, as stated, comes from words that mean “dust”. This is not surprising considering the color’s popularity in outdoor clothing.

We have already mentioned that khaki is a shade of brown, but this does not stop there from being other shades of khaki. Khaki hues can range from light colors to dark ones. Many people assume that “khaki” only refers to the light brown color. And indeed, this was its original meaning. These days, however, even darker shades of the original tan color are often referred to as “khaki”. As mentioned in the previous section, depending on who you ask, khaki can be a color or a fashion style.

Is Khaki a Color or a Material?

Although khaki originally referred to a specific type of brownish color, its meaning has now been expanded. Thus, you will often find clothing and other garments that are called “khaki” despite being other shades of brown or even green. “Khaki” also now refers to a particular style of clothing, one that is associated with the outdoors. A stereotypical safari adventurer or simply a hiker has clothes that are described as “khaki”.

Now that you know better about khaki, the next time you shop for your hike or climbing activity, you’ll know what to ask for and get. And with the added knowledge about khaki clothing, you might feel more like Indiana Jones, more than ready to search for treasures in the unknown!

There’s an activity that we take for granted even though we do it every day. It may seem like a simple activity, but without it, our lives would be completely different. That activity is walking; specifically, walking on two legs (also known as bipedalism). It’s a distinctive feature of humans, and while humans aren’t the only ones to do so, we would not be who we are without it.

Nevertheless, if you have the burning question in your head as to who invented walking: good news. This article has the answers to your question. While it will briefly discuss other forms of walking early on, it will largely focus on walking on two legs.

No One Invented Walking

It may be important to get this out of the way: walking wasn’t invented. Not by anyone or anything. Walking is an innate thing that has existed since animals began living on land hundreds of millions of years ago. Scientists believe that arthropods were the first creatures to walk on land. Specifically, millipedes are currently the oldest known land animals. They first appeared around Even before the first vertebrates to walk on land appeared, other groups such as insects, arachnids, and many other forms of life already walked on land. It should be worth noting that since most adult insects have legs, they tend to go around by flying. Still, they have legs, so they have to count as walkers, right?

The First Vertebrates to Walk on Land Evolved From Fish

Invertebrates walked (or crawled) on land for millions of years before vertebrates emerged from the waters. The first land vertebrates are believed to have evolved from a class of fish called Sarcopterygii, which actually still exist today. If you’re a fan of Animal Crossing and are familiar with one of the game’s rarest fish, the coelacanth, well you’ve seen a member of Sarcopterygii!

Scientists believe a group called Ichthyostega was one of the first if not the first vertebrate group to walk on land. It looks like a cross between Sarcopterygii and an amphibian. While some scientists believe that they may have been amphibious, they do not consider them to be true members of Amphibia. Nevertheless, amphibians would come to dominate terrestrial Earth until reptiles emerged and took their throne.

Reptiles Were the First to Walk on Two Legs

When people today think of reptiles that walk on two legs, the first group that comes to mind is probably the dinosaurs. After all, velociraptors and T-rex are ingrained in our pop culture! However, bipedalism actually emerged long before there were even dinosaurs.

The earliest known bipedal animal was a reptile called Eudibamus. There is actually some dispute as to whether or not it was fully bipedal. Nevertheless, due to its anatomy, scientists consider the Eudibamus an important figure in the evolution of bipedalism.

As for dinosaurs, both of the main kinds (Saurischia and Ornithischia) had many bipedal members, although it is worth noting that T-rex and velociraptors were both members of Saurischia. Indeed, dinosaurs didn’t actually fully go extinct when that asteroid hit. While most dinosaur groups died out 66 million years ago, one group of saurischians survived up to the present day.

Birds Became Dominant Bipeds

That’s right: dinosaurs are still very much with us even today in the form of birds. And you may have noticed something about birds: all of them are bipedal! That is because birds specifically descend from a group of dinosaurs called Theropoda. Members of this group, known as theropods, were largely bipedal. If you’ve ever seen or imagined an ostrich running and it reminded you of dinosaurs, well this is the reason.

Before Primates, There Were Others

Today, people largely think of primates as the main mammal bipedal group (even though not all primates are pure bipedal). However, primates are far from the first mammal group to have bipedal members. For example, kangaroos (which are marsupials and not primates) are bipedal. After all, they jump around on just two legs. Many rodents, such as squirrels, can either walk on two legs when needed or can stand on two legs. However, not all of these rodents are exclusively bipedal.

But Primates Are The Ones Known For Walking

Despite the association, not all primates are fully bipedal. Most, if not all, primates are capable of walking on only two legs. In practice, this is not always the case and many bipedal primates still move around using their front limbs. Many of our cousins in the family Hominidae, such as gorillas and chimpanzees, are like this.

As for humans, Homo sapiens (that’s us in taxonomy speak) isn’t the first human to walk on two legs. It isn’t even Homo erectus or Homo habilis. Instead, scientists believe that a species called Ardipithecus ramidus has this honor. Ardipithecus lived 4 million years ago in what is now Ethiopia.

Fun Fact: The famous skeleton Lucy got its name because the team that discovered her played the song “Lucy in the Sky with Diamonds” by The Beatles the day she was discovered.

So Who Invented Walking?

If you’ve watched the Pixar film, Luca, you may recall this question being asked. Perhaps you were even inspired by that line to search for the answer. If you wanted to know who invented walking: it wasn’t invented. Instead, animals evolved the ability to walk after emerging from the seas long before we were alive.

Amaranth

The color amaranth takes its name from the plants of the same name. It is a shade of red.

Incidentally, sources don’t seem to agree on what exact hue is considered amaranth. One source claims that the name refers to a shade of pink that’s actually the stereotypical color of bubblegum. Others suggest that the name refers to a darker shade that’s more similar to the eponymous plant. Whatever the case, the name and the color are definitely unique.

Australien

Australien is such an obscure color that it doesn’t even have a Wikipedia article. In fact, if you search for “Australien” online, you’re more likely to find hits about Australia. That’s because “Australien” is actually the German name for Australia.

As for the color, the 1897 fashion guide House Decoration gave the hue its name. The guide stated that the colors of the Outback inspired the name. The Outback, as you may know, is the large desert that makes up much of Australia’s territory. Like many deserts, the Outback has a brownish hue. However, the Outback’s brown is also somewhat reddish.

According to the aforementioned guide, the color was apparently quite popular in Victorian England. Many women’s dresses had the color.

Banan

Banan may be one of the rare colors on this list, but it’s probably the most delicious. As you can probably tell, it takes its name from the banana. Interestingly enough, it also has a very fun alternative name: “Banan-appeal”. Yup: you read that as “banana peel”! Incidentally, sources state that this shade is similar to the color you find within the banana peel, hence the name.

Oh, and by the way, the name “banana” itself may have come from an Arabic word meaning “finger”. Maybe this entry will make you crave a banana sooner rather than later.

Burlywood

Burlywood is one of those rare colors that have an exotic origin. It’s a shade of brown that gets its name from a tree native to India. In particular, the hue refers to the shade of brown seen in wood made from that tree. The tree in question, Butea frondosa, can also be found in the rest of South and Southeast Asia.

Celadon

If you’ve played Pokémon Red and Blue or their remakes and sequels, you may be familiar with this color. That’s because Celadon City is one of the cities in the games.

Celadon is a light shade of green that experts believe first originated in China. This is because celadon is the color of the most familiar form of jade. Indeed, if you think of things made from jade, they would typically have a celadon color.

Jade is not the only thing that can come in celadon, however. Many Korean porcelain ceramics also had this color. Indeed, “celadon” became a general term for Korean ceramics even if they came in other colors. That association was that strong.

Drake’s-Neck

No, this color is not named after the Canadian rapper or his neck. No, it has nothing to do with either the Toronto Raptors or the Hotline Bling meme. It does have to do with dinosaurs… sort of. We’ll explain why in a bit.

Drake’s-Neck is a pretty interesting name for a shade of blue. What does it have to do with dinosaurs? It does so in the most tenuous way possible. The color is named after a duck. Specifically, a male duck. A drake is a male duck, and many drakes have a dark blue color somewhere on their bodies. Those blue areas are what gave the color its name. And where do dinosaurs come in? Well, ducks are birds, and as you may have learned in school, birds descended from dinosaurs. In fact, many biologists say that birds are dinosaurs. So maybe you could say the color is named after a raptor, after all.
