Why We Flirt Just Like Animals: The Science of Sex

It is rather natural, we barely even notice we do it.

Tilting a head to expose the neck, smiling or laughing at something that really was not funny, moving closer to the person making unfunny jokes, mimicking their actions. Our body language is perhaps the most subtle expression of what we are really thinking and feeling, and is a crucial component of the courting dance known as flirting.

Though cheesy pick-up lines abound, a lot is conveyed even before words are uttered. A prolonged gaze or arched eyebrow gives clues to the person across the bar that you are interested without having to explicitly ask about his/her sign. Though the statistics differ, some attribute almost 80 percent of our first impressions to our stance and swagger. And because flirting helps both animals and humans find mates faster and easier, it is an evolutionary trait hard-wired in our brains.

Mice twitch their noses at potential mates, colourful peacocks strut around for admiring peahens, and pigeons puff their chests to look buff. As much as we have moved on from mice and feathers, we do much of the same, for the exact same reasons.

Genetic Peacockery

Because flirting is an easy way for us to display our genes, mating potential, and interest, nature put a lot toward its success. This is one of the reasons why some males birds have exotic plumes, why elk carry hefty antlers (a sign of a healthy immune system), and why male fiddler crabs have such large claws. He waves his in the air, alerting females to his whereabouts, and signaling them to come closer for a better look at his burrow, colourful shell, and flashy claw.

Much in the same way, we are physically programmed to indicate interest almost before we mentally have a say in it. Slight actions reveal a lot. Stance, eye movement, and gestures like leaning forward to talk to the person, or quick eyebrow raises are what scientists call contact engagement, signaling to the other mammal that you are prepared for things to potentially get physical. Perhaps most importantly, these signals show that you’re not intending to dominate or flee. Or not just yet, anyhow.

Read My Lips

Like a lioness presenting herself to a mate, women will arch their backs and show off their hips to indicate fertility. While both men and women will make prolonged eye contact with people they are interested in, a woman might also lick her lips, helping to bring visual attention to the mouth. If someone is staring at your lips he may be thinking of how to kiss them.

Though a man might not pound his chest like Tarzan while in a crowd, it is only because of social constraints. He is still trying to put forth his strong jaw, an indicator of high testosterone levels, and spread his arms and chest to look muscular and strong.

Yet he does not want to look too strong or threatening, so he laughs and smiles frequently. Confident and powerful enough to protect his brood; nice enough not to harm the doe.

Moves Have Messages

By studying humans in their natural courting habitat (usually bars), scientists have been able to document the movements we make when we are interested in someone else. As it turns out, we are all quite predictable.

A woman smiles, raises her eyebrows, opens her eyes wide, holds a gaze, fidgets with her hair, lowers and tilts her head, and laughs. A man might jut out his chin, try to make his chest appear as large as possible, unconsciously flex an arm, laugh aloud, and smile. But what do all these ridiculous gestures mean?

By comparing our actions with those of animals, it becomes clear that moves have messages. A woman tilts her head and shows off her neck as a sign of vulnerability and submission.

When a male dog approaches a female dog, she has been observed to turn her head and flattens her ears as if to say, “I’m a lover, not a fighter. Don’t bite.” The male dog naturally assumes the taller, dominant stance. Females tend to also steal sideways glances, just as we do when flirting, to show she is demure and hard to get, yet interested.

Monkey See, Monkey Do

Together, both sexes take part in mirroring, tending to sit or stand in similar positions, or pick up a drink at the same time. When one person leans in, another will do the same if she likes what she is seeing. The theory behind this is that people are drawn to others who are like them (if he picks his nose, put the mirror down.)

We also tend to point or gesture toward our object of desire. This means feet, hands, or the entire body will subconsciously be pointed toward him or her, opening up a line of physical—and hopefully verbal—communication.

Yet through all our coquettish gestures, anyone who has raised her eyebrows at a policeman knows that flirting is not always intended to seal the deal.

Flirting can be a default mechanism when we want to get something for nothing (a better table at a restaurant, another free cocktail on the airplane, a shortcut in line) or a comfortable and fun way to interact with new people. And it is certainly not reserved just for people we want to mate with; married people flirt with no adulterous intentions and platonic flirting happens all the time. Flirting opens windows of potential and can peak curiosity about what might happen, but it also leaves us with the ability to walk away, no harm done.

8 Fascinating Extinct Animals

In just the past few centuries, several of the world’s most fascinating animals have disappeared completely from our planet. Though some are certainly just the natural course of things, most of the animals on this list became extinct through human activity. Here are some truly fascinating but extinct animals…

1. Tasmanian Tiger

Though its name and appearance may suggest otherwise, the Tasmanian Tiger was not a tiger at all, but a marsupial. They became extinct on the mainland of Australia before the arrival of Europeans, but persisted on the island of Tasmania, which is famous for the Tasmanian tiger’s close relative, the Tasmanian Devil.

2. Elephant Bird

Measuring in at a whopping 10 feet tall and 880 pounds, the four species of elephant birds that lived on Madagascar were once the biggest birds on the planet. It’s unclear exactly when and how these massive flightless birds became extinct, though it is likely that human activity wiped out the elephant bird in the 17th century.

3. Quagga

When European naturalists and explorers first ventured into the plains of South Africa, they encountered the Quagga and its close relative, the zebra. Because the two species’ stripes varied so much between individuals, it was difficult to tell whether they were simply variants of the same species or distinct from each other. Before they were sorted out into two distinct species, unfortunately, they were hunted into extinction. The last known Quagga died in captivity in 1883.

4. Baiji

The Baiji dolphin, native to China’s Yangtze River, is thought to have only recently become extinct. With the rapid industrialization of its native waterway, the Baiji’s population suffered considerably. About 5,000-6,000 of the dolphins were living in 1950, and, during the last official survey in 2006, none were found.


5. Steller’s Sea Cow

Sea cows were the epitome of the “gentle giant” — something that, ultimately, led to their swift extinction. Growing to about 30 feet long, the slow-swimming sea cow was once abundant across much of the North Pacific. After less than 30 years of hunting by European seal hunters, fur traders, and sailors, Steller’s Sea Cow became extinct in 1768.

6. Irish Elk

With no living relatives alive today, and the latest fossil record dating back 7,700 years, it’s hard to fully imagine the Irish Elk today. Well, maybe not: picture a deer, only bigger. A lot bigger: the Irish Elk was, in fact, the largest deer to ever live, averaging about 7 feet just up to its shoulders, not to mention its nearly 90-pound antlers that had a width of 12 feet.

7. Passenger Pigeon

With a population once estimated to number in the billions, likely one of the largest bird populations in the world at the time, it’s astounding to consider that the North American Passenger Pigeon became extinct in just a century. So how exactly did that happen? Well, the pigeons were a cheap and abundant source of meat — an ideal protein source for slaves and the poor. The birds grouped together in massive flocks, where it was easy to kill many, usually several thousand, at once. Though conservationists attempted to save the bird, the last surviving passenger pigeon died in captivity in 1914.

8. Dodo

The Dodo bird earns the dubious distinction of being one of the most famous extinct animals of all. The extinction of the flightless bird opened the eyes of humans to the role we have in the demise of a species, or “[going] the way of the Dodo.” Native to the tiny island of Mauritius, which was uninhabited before the 1500s, the Dodo bird was unaccustomed to, and thus unafraid of, humans. This made them easy prey, and led to their extinction in just about century.
