Koko's not alone: Here are 5 other animals that are almost as smart as humans.

You're probably familiar with Koko, the famous gorilla who knows sign language.

Whether it's her recent comments about climate change or the various times she's adopted kittens to raise as her own, Koko is one impressive ape — and a humbling example of just how humanlike the animal kingdom can be.

(She also has her fair share of vocal detractors, just like her human celebrity counterparts. Because apparently some people aren't impressed by a gorilla who can communicate with humans.)

Does Koko understand the detailed and complex scientific concepts behind climate change? Probably not. Was her response in a recent video on the topic encouraged, edited, and maybe even scripted? Sure.

But who cares? Koko knows more than 1,000 words in American Sign Language! She has pets that she cares for! And, oh yeah, she's completely changed the way we think about what's possible in terms of animal intelligence.

And Koko isn't the only animal to show signs of self-awareness.

Obviously we can't look into a living brain to decide if it has a higher consciousness. But we can observe from the outside whether an organism can roughly acknowledge, "Oh, maybe that other gorilla wanted that banana 'cause he was hungry, and now he's sad, and I kind of understand what that would be like."

This is generally referred to as "Theory of Mind" — the ability to recognize the self and empathize with others. When we recognize this trait in animals like Koko, it means we have some kind of demonstrative evidence these animals see themselves in others' shoes — that they can project and understand the beliefs and desires of others.

Again, just because an animal possesses Theory of Mind doesn't mean their thought processes are as highfalutin as us self-important human-types. But that's OK; there's still a lot that they can teach us — about ourselves and our brains and the world around us.

Here are five more species that act surprisingly human.

1. Chimpanzees

Apes in general are closely related to humans on the evolutionary ladder, but gorillas like Koko aren't the only intelligent ones. Chimpanzees tend to be the go-to subjects for studying primate consciousness and with some pretty remarkable results.

One chimp, Washoe, learned more than 350 words of American Sign Language and even taught some to her son — without any human intervention.

There was also Lucy, who was raised from birth by a human family and became well-known for her proclivity toward gin and tonics and her clever use of household appliances to aid in her — ahem — extracurricular enjoyment of Playgirl magazine. (Which sounds kind of funny until you realize what it says about psychological abuse and captivity.)

2. Octopuses

Also known plurally as "octopode" and "octopii," octopuses haven't technically been observed to demonstrate "consciousness" or self-awareness in the ways that we lowly humans usually define them. (This normally involves plopping an animal in front of a mirror to see if it recognizes its own reflection, but that's kinda hard to do with an underwater creature that doesn't see the same way we do.)

But octopuses have been known to learn through observation and use their suckers to unscrew jar lids from the inside and can solve a Rubik's Cube faster than you, so we probably just don't have the tools to comprehend their vastly superior intelligence, and we should really just bow down to our tentacled overlords and pray that they have mercy when they finally rise from the depths to destroy us.

Also they're adorable (scientifically speaking).

3. Elephants

Although they have yet to master the art of ear-powered flight (Disney lied to us!), elephants do have the biggest brains on the planet, which is part of why they have such remarkable memories and even have the ability to distinguish between human genders and ethnicities.

On top of that, elephants have also shown a surprising knack for artistic prowess by painting with their trunks — and brushes aren't the only tools they can use, either. Granted, there has been some moral debate about the treatment of these elephant painters in captivity. But if it makes you feel any better, they've also been known to intentionally screw with humans who are trying to test their intelligence, and I always appreciate an animal that can stick it to the man.

4. Bottlenose dolphins

Fun fact: Dolphins actually have more complex brains than humans.

Perhaps this higher cognitive ability is why so many humans seek their help in dolphin-assisted therapy as well as dolphin-assisted childbirth. Sure, there's no real proof for the effectiveness of either practice — but hey, if that's your thing, go for it.

Like humans, dolphins are one of the only animal species that's known to have sex for pleasure. Well, probably; there's some question about what "sex for pleasure" entails exactly, and I already made the mistake of googling "dolphin sex" once today.

Dolphins, too, have been observed to trick their own human trainers and actually have their own complete translatable language, even if we can't whistle quite they do.

(They also have a legal right to privacy in the state of New Jersey, though I'm not sure if that says more about dolphins or New Jersey.)

5. Crows

Don't be fooled by their diminutive size: The brains of crows (and other birds in the corvid family) are proportional in size to those of primates. This means they're capable of complex reasoning — to the point that some researchers believe them to be as clever as the average 7-year-old human.

This could explain why crows tend to make friends with children in exchange for gifts. Unfortunately, there is no kindergarten system for corvids (that we know of), and thus, no one to teach the clever birds that stealing from other birds and hiding your own stashes of food so that others won't find it (suggesting that they understand the desires of others) is not the best moral practice.

Then again, a plurality of crows is called a "murder," which is insidious enough without them pulling the elaborate cons of human children. Did I mention they know how to create and use their own tools?

Take my advice: Don't mess with a murder.

All of these animals are capable of higher consciousness, just like us.

It's easy to project human feelings onto our pets. After all, most animals do experience basic evolutionary emotions like hunger, fear, and pain, so it's not that big of a step to imagine them understanding individual desires and complex issues.

But the animals above go much, much farther than that. And while it might seem cute and cuddly to think of other critters acting like we do, we can also learn a lot about ourselves by studying the animals who are close to catching up. 

Except for octopuses, I mean. When it comes to them, all that we can really do is wait until they conquer Earth and hope we live to tell the tale.  ¯\\_(ツ)_/¯

Harvard researcher Arthur C. Brooks studies what leads to human happiness.

We live in a society that prizes ambition, celebrating goal-setting, and hustle culture as praiseworthy vehicles on the road to success. We also live in a society that associates successfully getting whatever our hearts desire with happiness. The formula we internalize from an early age is that desire + ambition + goal-setting + doing what it takes = a successful, happy life.

But as Harvard University happiness researcher Arthur C. Brooks has found, in his studies as well as his own experience, that happiness doesn't follow that formula. "It took me too long to figure this one out," Brooks told podcast host Tim Ferris, explaining why he uses a "reverse bucket list" to live a happier life.

bucket list, wants, desires, goals, detachment Many people make bucket lists of things they want in life. Giphy

Brooks shared that on his birthday, he would always make a list of his desires, ambitions, and things he wanted to accomplish—a bucket list. But when he was 50, he found his bucket list from when he was 40 and had an epiphany: "I looked at that list from when I was 40, and I'd checked everything off that list. And I was less happy at 50 than I was at 40."

As a social scientist, he recognized that he was doing something wrong and analyzed it.

"This is a neurophysiological problem and a psychological problem all rolled into one handy package," he said. "I was making the mistake of thinking that my satisfaction would come from having more. And the truth of the matter is that lasting and stable satisfaction, which doesn't wear off in a minute, comes when you understand that your satisfaction is your haves divided by your wants…You can increase your satisfaction temporarily and inefficiently by having more, or permanently and securely by wanting less."

Brooks concluded that he needed a "reverse bucket list" that would help him "consciously detach" from his worldly wants and desires by simply writing them down and crossing them off.

"I know that these things are going to occur to me as natural goals," Brooks said, citing human evolutionary psychology. "But I do not want to be owned by them. I want to manage them." He discussed moving those desires from the instinctual limbic system to the conscious pre-frontal cortex by examining each one and saying, "Maybe I get it, maybe I don't," but crossing them off as attachments. "And I'm free…it works," he said.

"When I write them down, I acknowledge that I have the desire," he explained on X. "When I cross them out, I acknowledge that I will not be attached to this goal."

The idea that attachment itself causes unhappiness is a concept found in many spiritual traditions, but it is most closely associated with Buddhism. Mike Brooks, PhD, explains that humans need healthy attachments, such as an attachment to staying alive and attachments to loved ones, to avoid suffering. But many things to which we are attached are not necessarily healthy, either by degree (over-attachment) or by nature (being attached to things that are impermanent).

"We should strive for flexibility in our attachments because the objects of our attachment are inherently in flux," Brooks writes in Psychology Today. "In this way, we suffer unnecessarily when we don't accept their impermanent nature."

What Arthur C. Brooks suggests that we strive to detach ourselves from our wants and desires because the simplest way to solve the 'haves/wants = happiness' formula is to reduce the denominator. The reverse bucket list, in which you cross off desires before you fulfill them, can help free you from attachment and lead to a happier overall existence.

Stop struggling with small talk by using the easy 'COST method'

This simple acronym will make your next social gathering a lot more enjoyable.

A man and woman chatting at a dinner party.

There are several reasons why people are hesitant to engage in small talk at a party or around the water cooler at work. Some people simply avoid it because they don’t find chatting about the weather, sports, or what they saw on television the night before very interesting.

Others are afraid that they may run out of things to say or that there will be an awkward pause that makes them want to hide their head in the sand, like an ostrich. Mary, a friendship educator with a degree in interpersonal communication, has a solution for those of us who want to be friendly and meet people but abhor small talk; she calls it the COST method.

What is the COST method for making small talk?

According to Mary, who goes by @better.social.skills on TikTok, COST stands for Compliment, Observation, Story, and Tip. These are four options you can turn to when you're in need of a conversation topic.

@better.social.skills

Remember the acronym C.O.S.T. and you’ll always have something to talk about at parties or events. C stands for compliment. Tell somebody you like their shirt or shoes, for example, and see where the conversation leads. O stands for observation. Remark on something happening around you, like if you enjoy the music or feel a certain way about the weather. A stands for story, in which you share a little anecdote about yourself. For example, maybe you were late to the party for some reason, or you’re excited to get home and watch a show you’re loving. T stands for tip, in which you give a small recommendation to someone. For example, where the shortest bathroom lines are, which food is particular particularly delicious, or point out an interesting person they might want to talk to. What do you think? Would you use these? #creatorsearchinsights #conversationstarters

1. Compliment

“Tell somebody you like their shirt or shoes, for example, and see where the conversation leads,” Mary says.

“Oh, I like your shoes.”

“I like your shirt.”

“You have such a soothing voice.”

2. Observation

“Remark on something happening around you,” Mary says.

“This song is amazing.”

“I really love how Jeanie decorated this room.”

“There’s a lot more people here than last night.”

3. Story

“Share a little anecdote about yourself. For example, maybe you were late to the party for some reason, or you’re excited to get home and watch a show you’re loving,” she said.

4. Tip

“Give a small recommendation to someone. For example, where the shortest bathroom lines are, which food is particularly delicious, or point out an interesting person they might want to talk to,” Mary said.

“I don’t know if you’ve tried the new Mexican place on South Street yet…”

“I’d have one of Jeanie’s margaritas now, before they are all gone.”

“Be careful if you talk to Brian. He can get a bit long-winded.”

The great thing, if you’re a little shy about making small talk, is that studies show that you definitely don’t need to do all the heavy lifting in the conversation. In fact, a Gong.io study found that the best way to make a connection with someone is to speak 43% of the time and let your new friend talk for the other 57% of the conversation.

Further proof that the best way to make a great first impression is a study published in the Journal of Personality and Social Psychology. It found that when meeting someone for the first time, ask them a question and then be sure to ask two additional follow-ups before discussing yourself. This has been found to dramatically increase your likability.

“We identify a robust and consistent relationship between question-asking and liking,” the authors of the study write. “People who ask more questions, particularly follow-up questions, are better liked by their conversation partners.”

For those of you who have always felt that you're bad at making small talk. while others seemed to do it naturally, realize that people aren’t born great communicators; it’s a skill that can be learned just like anything else. With a few tips from the experts, you can go from dreading small talk to enjoying striking up a conversation with just about anyone.

A lot of people are uncomfortable making small talk, but it’s an essential skill that can make or break your love life, career, and social experiences. Many people believe that being good at chatting with others is something innate, but those who excel at it work at their craft and pick up small tips along the way to become better communicators.

One of the tricks that all great communicators know is that you will be more likable when you're more interested than interesting. Study after study shows that people love talking about themselves, and if you ask people more questions, they will like you a lot more than if you did all the talking. So, how do we do this without creating a one-sided conversation where your conversation partner learns nothing about you? The folks at the Science of People have shared the statement-plus question technique.

The statement-plus technique

“One of the smoothest ways to keep conversation flowing is to share a brief personal statement followed by a question,” the Science of People writes. “This technique accomplishes two things: it gives the other person information about you (making you seem more approachable and interesting) while also redirecting focus to them.”

Here are some examples:

Instead of asking “What do you do for work?” say:

“I’m a writer for Upworthy, and I enjoy seeing my work read by millions of people. What excites you about your job?”

Instead of asking, “Where do you live?” try:

“I live in Long Beach, California, and it’s really nice living by the ocean. What do you love the most about where you live?”

Instead of asking, “How do you know the person who threw the party?” say:

“I met Sarah at a church meeting seven years ago. Do you remember the first time you met her?”

These questions enable you to discuss yourself while maintaining the focus on the other person. They are also open-ended, so you don’t just get a one-word answer. You learn their job and what excites them about it. You know where they live, and they get to brag about what they like about the city. The technique also broadens the conversation because, according to the psychological phenomenon known as reciprocal self-disclosure, people are more likely to disclose things about themselves after you share something about yourself.

What is reciprocal self-disclosure?

“The most likely result of your self-disclosure is that other people will do the same. In the field of communication, we refer to this as 'reciprocity.' When you share information about yourself, the most likely result is that people will start to disclose a similar type of information from their own lives," communication coach Alexander Lyon says. "In our presentations, we talk about this as a magic wand. Disclosure is the closest thing we have to a magic wand in terms of a concept in communication. When you disclose, other people almost automatically reciprocate."

Ultimately, people love to talk about themselves, and if you give them the opportunity, they will like you more for it. However, that doesn’t mean you can’t reveal some aspects of yourself at the same time while keeping the focus on them. The statement-plus question technique allows you to reveal some things about yourself while making the other person feel seen and comfortable telling you more about themselves. It’s sure to elevate your small talk to something more substantial in a relaxed way that doesn’t feel like an interview.

Did Julius Caesar have his armpits plucked? Probably.

Modern life may have us shaving, waxing, microblading, laser treating, Botoxing, and altering our natural appearance in all manner of ways in the name of beauty, but the idea of grooming to specific societal standards is nothing new. In cultures all around the world and throughout history, humans have found countless creative ways to make ourselves (ostensibly) look better.

Of course, what looks better is subjective and always has been. Take, for example, the ancient Romans. If you wanted to be seen as a studly man 2,000 years ago in the Roman Empire, you'd remove as much of your body hair as possible. That meant tweezing—or being tweezed by someone else, most likely an enslaved person.

The Romans, in general, weren't big on body hair for men or women.

"You had to have the look,” Cameron Moffett, English Heritage’s curator at the Wroxeter Roman City museum in Shropshire, U.K., told The Times. “And the look was hairlessness, particularly the underarms.” A collection of 50 tweezers on display at the museum, recovered from the archeological site that was once the Roman city of Viriconium, speaks to Roman tweezing habits, but that's not the only evidence we have.

Stoic philosopher Seneca once wrote in a letter lamenting how the noise from the Roman baths was disrupting his work: "Besides those who just have loud voices, imagine the skinny armpit-hair plucker whose cries are shrill to draw people's attention and never stop except when he's doing his job and making someone else shriek for him."

When we picture the ancient Romans, "skinny armpit-hair plucker" may not be the image that comes to mind, yet here we are.


teeth brushing, toothbrush, oral hygiene, toothpaste, dental hygiene They brushed with what now? Giphy

While we fret over fluoride, the Romans brushed their teeth with pee and mouse brains.

Toothpastes of the past were made with all kinds of things—herbs, spices, salts, crushed bone, and more. For the ancient Romans, that "more" included mouse brains and human urine, according to Decisions in Dentistry. Mouse brains were believed to enhance the effectiveness of toothpaste, and urine, imported in large quantities from Portugal, was utilized for its ammonia content and whitening properties. A standard Roman toothpaste would be a mixture of herbs, mouse brains, urine, and a binder such as honey. Oddly enough, it appeared to be somewhat effective, with archeological findings showing a relatively low number of cavities and tooth decay.

Sailorr has everyone talking about her sound - and her teeth. Here’s my super short history lesson on the practice of ohaguro #ohaguro #geisha #japanese #japantok #aapi #history #japan #historytok #sailorr #japanesebeauty

Meanwhile, in ancient Japan, women tried to blacken their teeth

Teeth whitening is all the rage in modern times, but in the distant past in parts of Asia, making your teeth black was considered beautiful. The practice known as ohaguro was a traditional Japanese practice that, ironically, was intended to prevent tooth decay.

According to a letter in the British Dental Journal, women in ancient Japan would paint a solution of ferric acetate (from iron filings), vinegar, and tannin from tea or vegetables. It was called kanemizuonto and made the teeth appear black. The practice has made a comeback among some rural areas of Southeast Asia, and the Vietnamese-American singer Sailorr has made waves with her blackened teeth as well.

Ear pickers were much prettier than Q-tips. In fact, they were an accessory.

The old saying, "Don't put anything in your ear except your elbow," may not be as old as it seems, as people have been inserting objects into their ears to remove wax for a long time.

In the 16th and 17th centuries, it was common to see beautiful, ornate "ear pickers"—small metal tools with a small scoop at the end for cleaning ears as well as teeth and fingernails. According to Jamestown Rediscovery, it was fashionable to wear gold and silver toiletry tools, such as ear pickers or toothpicks, as accessories. It's hard to imagine wearing Q-tips and toothpicks around. Also, ew. But if you look up "ear pickers," you'll find ornate examples from various parts of the world.

At the very least, it's nice to know that modern humans are not the first ones to go to great—and sometimes interesting—lengths to meet an arbitrary social standard of beauty. (And three cheers for modern toothpaste. Seriously.)
