CONVERSATION IS A SURVIVAL SKILL
E-volve comes from âto roll out.â Con-verse comes from âto turn together.â We can rightly say thatâas we turn together in conversation, we become the evolution weâve been waiting for.

Nuanced conversation is a uniquely human skill. Biologists think itâs a compelling force behind our success as a species and our ascent up the food chain. Although the precise chronology of when humans first started talking is still up for debate, it is safe to say that weâve been jabbering coherently for at least a million years.
How has this ability helped us? Well, for one thing, we can lie and other animals canât. When a cat doesnât like you, you know it. A dog canât fake a growl and elephants, so far as we know, canât pretend to grunt. Humans can dissemble and, while that might be seen as a flaw, itâs often useful.
For example, imagine you couldnât pretend that you like your mother-in-law or your boss. Imagine you couldnât tell your friend whoâs had a rough day that her haircut looks great. Imagine you couldnât tell your prospective employer that you planned to stay with the company for at least five years. Lying carries a negative connotation for good reason, but itâs also an essential skill. And itâs one that only humans have, to the best of our knowledge. (My dogs pretend they havenât been fed in the morning to see if they can coerce a second breakfast out of my son, but I guess science doesnât consider that âlying.â)
Conversation has long been a crucial asset to us as a species. Compared to other creatures, physical attributes are not among our strengths. We admire the swiftness of the snow leopard, the poison of the Komodo dragon, or the sheer power of a polar bear. Iâm sure we all know that we canât win a hand-to-paw fight with a grizzly bear. We are not at the top of the food chain, of course.1 On a scale of 1 to 5, we score 2.21. That puts us on a par with anchovies.
And yet, despite all of our physical weaknesses, we are the dominant species. It is perhaps because of our comparatively fragile forms that humans have had to find other ways to compete, and talking was one of our most powerful tools. Seth Horowitz, an auditory neuroscientist, says this:
Many evolutionary biologists posit that humans developed language for economic reasons. We needed to trade, and we needed to establish trust in order to trade. Language is very handy when you are trying to conduct business with someone. Two early humans could not only agree to trade three wooden bowls for six bunches of bananas but arrange terms as well. What wood was used for the bowls? Where did you get the bananas? That transaction would have been nearly impossible using only gestures and unintelligible noises, and carrying it out according to terms agreed upon creates a bond of trust.
Language allows us to be specific, and this is where conversation plays a key role. Your cat can tell you that heâs in pain and in a lot of pain, but he canât tell you what hurts or describe the injury. We can do that, plus rank the pain on a ten-point scale, tell you when it started hurting, and whether itâs a shooting pain or more of an ache. Thatâs a powerful survival tool.
Some scientists suggest language evolved as a part of mating. We can observe a similar phenomenon in other species. The ability to make certain sounds and imitate others might make you attractive to a member of the opposite sex. (Although when it comes to human mating, this skill can prove to be a double-edged sword. Iâm reminded of Abraham Lincolnâs words: Better to remain silent and be thought a fool than to speak and to remove all doubt.)
Whatever the original imperative for human speech, we have developed languages that rise far above a dogâs warning bark or a snakeâs intimidating hiss. âWe can use our language to look into the future,â says evolutionary biologist Mark Pagel, author of Wired for Culture. â[We can] share the thoughts of others, and benefit from the wisdom of the past. We can make plans, cut deals, and reach agreements. We can woo prospective mates and threaten our enemies. We can describe who did what to whom, when they did it, and for what reason. We can describe how to do things, and what things to avoid.â3
In fact, the human body is uniquely evolved for conversation. We started out with the same basic equipment that chimps have: lips, tongue, lungs, throat, soft palate, and larynx. Those tools allow us to make noises.
(Actually, if your goal is just to create sounds and not specific noises, you donât even need a throat, just a balloon. Inflate it and then let the air out slowly while you change the size of the neck. See the thin plastic vibrating at different speeds as you stretch it out or relax it? Thatâs similar to what happens inside your throat. Your vocal cords vibrate as breath passes over them.)
But we needed to make more than noises. And one of the ways we evolved differently from our ape cousins is that we developed the ability to form words. Our mouths shrank while our necks got shorter. Our lips became more flexible. Weâve even paid a high price for this evolutionary advantage because our larynx eventually moved farther down our throats. We have an additional open space back there called the pharynx. The pharynx is formed of walls of muscle that move food into the esophagus and warm up the air we breathe before it travels to the lungs.
These changes to our mouths and necks made it possible for us to form words, but they also meant that food must travel farther, past the larynx to the esophagus, in order to be digested. If it gets stuck along the way and blocks our airway, we choke. Consider that for just a moment: the human race risks death in order to communicate more clearly. Thatâs how crucial language is to our species.
Itâs important to note that language is not the same as communication. We can communicate in complete silence, using gesture, eye contact, and touch. But language is required for conversation. Although sign language is silent, for example, it is still a formal language with vocabulary and sentence structure.
There are a number of theories that speculate how humans first developed language, but my favorite is that of Shigeru Miyagawa, a professor of linguistics at the Massachusetts Institute of Technology. Miyagawa has built on the work of other linguists such as Noam Chomsky and Kenneth Hale; he argues that humans probably developed language as we know it by combining the gestural language of other animals with the songs of birds.
Gestural language is a wave of greeting or pointing to show a directionâthink of the dance a bee performs to relay the location of pollen-rich flowers. We can understand the meaning of one gesture, like pointing, thatâs used in isolation, just as we understand the meaning of one word, like âfire.â
But birdsong canât be picked apart. It is the expression layer. The message is communicated holistically. In other words, you need to hear the song in its entirety to understand its meaning; it dissolves into nonsense if you try to separate it into individual pieces, just as a hieroglyph loses its meaning if you pull out individual lines. Miyagawa believes that gestures and individual words were eventually not enough for us to communicate all that we wanted to say, so we added nuanced expression.
This is why Miyagawaâs theory is my favoriteâbecause it suggests that humans sang before they spoke.
Weâve forgotten how crucial communication is to our species, and that has perhaps made it easier to accept the disintegration of modern conversation. We may not realize how dependent we have been, historically, on our ability to communicate. It has been millennia since language and conversation became part of our survival. In that time, we have improved the tools for communication exponentially. But have we improved the communication itself? Have we improved what we say, how we say it, and how we receive what others tell us?
In a word: no.
There are two important reasons why we need to get better at talking to one another. One is economic; the other is human.
First, business: poor communication costs us about $37 billion a year, according to a study from training provider Cognisco.4 That boils down to a tally, per worker, of more than $26,000 annually. And that calculation only includes companies with more than one hundred employees. Imagine how much higher that number would be if we included all businesses.
Good communication, on the other hand, is quite profitable. Companies with leaders who are great communicators have nearly 50 percent higher returns than companies with unexceptional communicators at the helm.5 When retail giant Best Buy commissioned an in-depth study of the companyâs internal communications, one of the more notable insights gleaned was that for every percentage point the company increased employee engagement through communication, stores saw a $100,000 annual increase in operating income.
And according to research by Nobel Prizeâwinning psychologist Daniel Kahneman, author of Thinking, Fast and Slow,6 most people would rather do business with someone they like and trust than someone they dislike. I realize that may seem like a no-brainer, but get this: customers will choose a likable person over a less likable one, even if the likable personâs product is lower quality and higher priced.
Hereâs another way to look at it: consumers in the United States return about $14 billion worth of electronics every year. But in 85 percent of those cases, thereâs nothing wrong with the merchandise. The consumer just doesnât understand how to use the device after opening the box. Sometimes weak documentation (such as an indecipherable instruction manual) is to blame; other times the culprit is insufficient âcustomer education,â the formal term for the casual conversations salespeople have with customers about a product.
That translates to nearly $12 billion a year lost because instructions werenât clearly communicated. And in reality, this represents only a front-end loss because many consumers wonât go back to a company after theyâve had to return a product they didnât understand how to use. Billions upon billions of dollars could be saved with good, clear communication.
The research on poor communication is extensive and alarming. I mentioned earlier that lives are affected by communication in hospitals, but dollars are at stake there as well. Researchers at the University of Maryland found that so-called communication inefficiencies cost US hospitals about $12 billion every year.7 Thatâs a conservative estimate. It includes wasted time on the part of doctors and nurses, but over half of the cost stems from extra days that patients spend in the hospital because of information that wasnât shared in a timely or clear manner.
Communication also affects employee retention. No manager wants high turnover because itâs expensive, regardless of the size of the business. It can cost more than $3,500 to replace one employee making $10 an hour.8 A general rule of thumb is that it costs about 20 percent of an employeeâs annual salary to replace them. In other words, if the employee makes $35,000 per year, it will cost about $7,000 to replace that employee. So, losing an employee to miscommunication and lack of engagement is truly a waste of dollars and time.
But bad communication negatively affects our decisions on the front side of the hiring equation as well. Iâm sure many HR administrators have had reason to think they hired the wrong candidateâbut have they taken the time to figure out what went wrong? Hiring mistakes can sometimes be traced back to the job interview, to the questions that were asked and the responses that were offered. When it costs thousands to replace even a minimum-wage worker, those conversations can be measured in dollars and cents.
For example, a lot of hiring managers make the mistake of assuming that someone who talks well and a lot will be a good salesperson. The idea is that if someone is an entertaining storyteller, he or she must be great at seducing a client. But often the truth is just the opposite. Some of the most effective salespeople, the ones who sell the most, are those who can listen and respond.9 Those who can hold good, balanced conversations are the ones who ultimately close the deal.
Our communication skills at work are not only shaky, they are also too seldom put to use. Many of us are guilty of firing off a quick e-mail when we could have walked down the hall to chat with a colleague or picked up the phone. Research shows that we are more likely to get our message across through conversationâeither in person or on the phoneâthan we are using a written message. And yet, we...
