Charles Darwin’s theory of natural selection explains how organisms adapt over generations, passing advantageous traits to their offspring. In today’s world, however, 10 ways modern technology is intervening in that age‑old process, nudging human evolution in directions our ancestors never imagined. From medical breakthroughs to everyday gadgets, each innovation is subtly rewriting the script of survival.

10 Cesarean Sections Make Women’s Hips Narrower

Elective C‑sections are gradually producing a generation of women with tighter pelvic dimensions. In earlier eras, a narrow pelvis often meant fatal complications during childbirth, preventing the transmission of those genes. Today, surgical delivery lets women with smaller hips survive and give birth to children who inherit the same trait.

Recent data indicate that 36 per 1,000 newborns now possess a narrow pelvis, up from 30 per 1,000 in the 1960s. Evolutionary theory might suggest that wider hips would dominate, but humans historically favored smaller infants that could navigate tighter birth canals, not larger babies that required broader openings.

Ironically, C‑sections are now encouraging a reversal: larger babies are being delivered despite mothers’ constricted pelvises, which could drive the procedure’s prevalence even higher in the decades to come.

9 Mobile Phones Are Causing Horns To Grow In Our Skulls

Constantly tilting our heads down to stare at smartphones creates pressure at the junction where neck muscles meet the skull. This stress stimulates the formation of a bony protrusion—known as an external occipital protuberance—that resembles a tiny horn at the back of the head.

People with this growth can often feel the ridge with their fingertips, and it may even be visible on a bald scalp. The phenomenon isn’t exclusive to phones; any activity that forces the head into a prolonged forward bend can trigger it, though smartphones are the most prevalent culprit in modern life.

While reading a book also bends the neck, the frequency and duration of smartphone use far exceed traditional reading habits, making this skeletal adaptation increasingly common.

8 Search Engines Are Making Us Forgetful

Imagine being quizzed on the year Martin Van Buren became U.S. president. Most people would reach for a search engine rather than recall the date from memory. This behavior exemplifies the “Google effect,” a tendency to forget information that can be quickly retrieved online.

In a 2011 study by Betsy Sparrow, Jenny Liu, and Daniel Wegner, participants were more likely to abandon recall attempts when they knew the answer was just a click away. The mere awareness that information is readily accessible—whether on the internet or stored on a phone—reduces the brain’s motivation to retain it.

Consequently, even facts we deem important can slip away if we trust a digital backup. For reference, Martin Van Buren assumed office in 1837.

7 Farming Made Our Jaws Smaller

Early hunter‑gatherers boasted broad faces, robust jaws, and large teeth—adaptations for chewing tough, uncooked foods. About 12,000 years ago, the agricultural revolution introduced softer, cultivated crops, and with it, a gradual shrinkage of our dental arches.

Because cultivated plants required less mastication, the selective pressure for massive jaw muscles relaxed. Coupled with cooking, which further softened food, human jaws diminished in size, often leaving insufficient room for all teeth.

This dietary shift also lightened our skeletal structure, particularly around joints, not merely from softer fare but from a less physically demanding lifestyle that no longer required the stamina of a predator.

6 Processed Foods Are Changing Children’s Faces

The composition of a child’s diet directly influences the development of their skull, jaw, and overall facial structure. Modern reliance on highly processed foods—often low in essential nutrients and requiring minimal chewing—has led to a noticeable trend: children’s faces are becoming less robust.

Natural, whole foods compel youngsters to exercise their jaw muscles, fostering stronger bone growth. In contrast, processed items reduce chewing effort, resulting in weaker jaws and smaller cranial dimensions. Studies suggest contemporary skulls are 5‑10 % smaller than those of Paleolithic ancestors.

This shift isn’t limited to humans; animal studies reveal similar facial deformities when young specimens are raised on processed diets, underscoring the broad impact of modern nutrition on skeletal morphology.

5 Social Media Is Destroying Our Lives

Extensive research links heavy social‑media use to a suite of mental‑health challenges: depression, anxiety, low self‑esteem, and diminished concentration, especially among teenagers. The pervasive fear of missing out (FOMO) drives compulsive checking, amplifying these issues.

Critics argue that correlation does not equal causation, suggesting that individuals already prone to loneliness gravitate toward social platforms. Nevertheless, a University of Pennsylvania experiment with 143 participants showed that reducing social‑media exposure led to measurable improvements in mood and a drop in loneliness.

Interestingly, both groups in the study reported a decline in anxiety and FOMO over time, possibly because participants became more mindful of their digital habits during the trial.

4 Smartphones Have Reduced Our Attention Span

Our brains possess an innate sense of timing, predicting when events will occur—like the precise moment a handshake should be extended. When we habitually glance at our phones every few minutes, the brain learns to anticipate these intervals, effectively rewiring our internal clock.

This constant expectation erodes sustained focus. Instead of immersing in a task, we find ourselves pre‑emptively reaching for the next notification, a behavior linked to reduced activation in brain regions responsible for deep concentration.

Research shows that heavy phone users must exert greater mental effort to stay on task, confirming that the device’s pull fragments attention and hampers productivity.

3 The Internet Is Making Us Unable To Cope Offline

In 2011, Professor David Levy coined the term “popcorn brain” to describe how relentless online stimulation reshapes our cognitive abilities. Individuals with this condition become so engrossed in digital streams that they lose interest—and even competence—in offline activities.

Levy’s research revealed that constant email checks, message notifications, and web browsing create a compulsive desire for fresh information, shortening attention spans and inflating expectations for instant gratification.

Supporting data indicate that students who spend ten hours daily on the internet perform worse on cognitive tests than peers who limit their online time to two hours, underscoring the detrimental effect of excessive digital exposure.

2 Technology Is Causing Nearsightedness In Children

Myopia, or nearsightedness, has surged dramatically in tech‑saturated societies. In China, a staggering 90 % of teenagers now suffer from myopia, a sharp rise from the 10‑20 % prevalence six decades ago. Similar spikes appear across Europe, the United States, and South Korea, where over 96 % of 19‑year‑old males are affected.

The primary driver appears to be reduced outdoor time. Indoor environments lack natural sunlight, a crucial factor for proper eye development. Conversely, Australian youths, who spend ample time outdoors, exhibit markedly lower myopia rates.

Researchers propose that exposing children to at least three hours of daylight daily could reverse this trend, offering a simple yet powerful preventive measure.

1 Smartphones Are Causing Insomnia

Smartphones have earned a notorious reputation for disrupting sleep, and the science backs it up. When a device rests on the nightstand, its alerts, vibrations, and the temptation to scroll can jolt a sleeper awake or delay bedtime entirely.

Beyond the obvious distractions, the blue light emitted by screens tricks the brain into thinking it’s still daylight, suppressing melatonin production—the hormone that signals the body it’s time to rest. This effect is negligible during the day but becomes a major obstacle to falling asleep at night.

Consequently, habitual bedtime phone use can evolve into chronic insomnia, eroding overall health and daytime performance.

10 Ways Modern Technology’s Impact on Evolution

From narrowed pelvises to digital‑induced insomnia, the ten examples above illustrate how 10 ways modern innovations are subtly but powerfully reshaping human biology and behavior. As we continue to integrate technology into every facet of life, understanding these shifts becomes essential for navigating our evolutionary future.

We can all agree, the general consensus among the majority of hard working people today, that our beds become our best friend at the end of each and every long enduring work day.  Up early and to bed late, with a million and one to-do list items in between, the day is never long enough to get it all done.

If we had the choice between the to-do list and a never ending night’s sleep, we’d probably all fall for the latter.  Unfortunately, a Snow White induced nap isn’t possible for all of us in the non-Disney world, so I’m sure most of us would take at least one good restful night’s sleep every once in a blue moon instead.

A consistent good night’s sleep is at the top of every health list.  Be it ways to lose weight, avoid the flu, stay young forever, or lessen chronic pain.  Right next to staying hydrated, a restful night is the key factor in staying healthy and creating a life of longevity.  Our sleeping habits directly affect our health: mental, physical, and emotional.

Lack of sleep creates heightened stress hormones, weakened immune system, and ultimately a shorter life span.  So what happens when a restful sleep isn’t possible?  Are you doing everything Google says to do when it comes to creating a peaceful bedroom atmosphere, turning off all of your electronics, avoiding caffeine and exercise after 2 p.m. everyday and finding the best memory foam mattress?

As much as it pains to admit it, the very mattress you call your best friend every night could be the culprit killing your REM cycles and ultimately your health.

Now that I have the attention of all you sleepy little princes and princesses, I’d like to give you a gift in the form of a shiny, red apple laced with a sleeping potion that will help you drift off into dreamland for at least a solid 8 hours, but since that isn’t possible I’ll give it to you in form of list outlining the top ten reasons your old mattress is destroying your health.

10. Your old mattress equals restless nights equals no sleep equals being tired.

This may be the most obvious point, but it is important to note nonetheless.  If your mattress is old and uncomfortable you will most assuredly not feel cozy and snuggled, which means you’ll be tossing and turning, waking up constantly, never really achieving your full REM cycles and ultimately wake up tired and feeling more exhausted each morning. This will lead to all of the symptoms we talk about in the following 2-10 points.

Being tired leads to a lot of pretty bad outcomes. If you can’t sleep you can’t function on the most basic levels preventing you from making better decisions for your health on a daily basis.

9. Your old mattress equals all the pain.

So.  Much.  Pain.  An old mattress starts to lose its shape, it becomes lumpy and saggy.  It loses firmness and foundation that is supposed to keep you supported.  When your body isn’t supported it will put pressure on your joints, tilt and angle your body in a contorted fashion giving you all those lovely “kinks” in your muscles, tendons, and nerves.  If you are in constant pain from the sleep that is supposed to be refreshing your body and mind you won’t be able to move easily and fluidly.  This will most likely lead to a more sedentary lifestyle of now not only being uncomfortable in your bed but also all day every day.

8. Your old mattress equals little bugs plus allergens.

We all know about the microscopic organisms that hang out all over your body and make your skin literally crawl just thinking about the little critters.  Even the cleanest person in the world can’t escape the teeny tiny bugs that eat our dead skin cells and bathe in our body oils.

The bugs, the skin cells, and the oils all collect and build up on our mattress, blankets, pillows, and pajamas.  The build up, no matter how many times we wash the linens, creates a prime breeding ground for molds, bacteria, and even bigger bugs – dust mites.

Hey so now that you know about the dirty little inner city that you’re constructing on a nightly basis let’s think about how breathing all of that in adds to your allergen issues and creates throat and lung complications.  Yummy.

7. Your old mattress may equal bed bugs.

I’m just gonna leave this here for your reading pleasure – Bed Bugs are Pure Evil.  However, just to summarize I’d like to reiterate how evil these little buggers are, they are easy to contract and oh so difficult (and expensive!) to rid yourself of.  They cause health problems and diseases.  They suck your blood, reproduce faster than rabbits, and are resistant to everything but a very specific set of procedures that should be held under lock and key to prevent any future mutational and evolutionary resistance.  Being a clean person has no effect on them, let’s face it a brand new mattress is just as susceptible as an old one.

A small history lesson: bed bugs weren’t always this savvy, they were almost completely eradicated completely but then quickly evolved into the strong little devils we now know and have to put up with today.

6. Your old mattress equals so many health problems.

Lack of sleep means more stress hormones, it means mental inconsistencies which leads to poor decision making, followed by poor health choices such as what we eat or the risks we take.  Being exhausted wears on the body to the point of no return.  Here’s the shortlist: obesity, weakened immune systems, heart conditions, increased stress and anxiety, blood pressure issues, possibility of stroke, diabetes, and a higher risk of an earlier death!  Let’s not to mention what the mattresses are made of, materials and toxins we breathe in and soak up through our skin every night constantly, just to name a few: boric acid, formaldehyde, petrochemicals, and polyvinyl chloride (aka PVC).

5. Your old mattress may equal sleep apnea or at the very least, snoring.

Sleep apnea is serious, and there are many kinds and causes.  Some doctors believe some mattress types could make the problem worse.  But at the very least, if you aren’t being supported properly by your mattress it may kink your body in certain positions making you snore at night.  Even if you don’t have a partner sleeping next to you, snoring can cause breathing issues and noise pollution in the room adding to your restless night.

4. Your old mattress equals more mental clutter and thus more physical chaos.

Sleeping less efficiently effects the efficiency of the mind and body in ways other than pure immune health.  Our brains refresh while sleeping, clearing away all the clutter and unnecessary chaos.  When we don’t sleep the chaos and clutter remain and it all continues to build.  It causes memory issues, critical thinking skills, depression, impaired judgement, physical accidents and affects the ability to learn new skills and abilities and retain or retrieve information.

3. Your old mattress equals aging skin.

Lack of sleep raises your stress hormones, which wears and tears on every single micro millimeter of your body, including the biggest living, breathing organism – your skin.  Eye bags, wrinkles, and fine lines all around your face show that wear and tear and it shows unfavorable to your chronological age.  Good sleep not only keeps our brains in good working order, but also allows all of our organs to rest, giving them a chance to build immunity to the cold hard world we expose them to every day.

2. Your old mattress equals less nookie.

Exhaustion and physical tension causes a lower libido.  Desire and interest as well as initiative all decrease when you’re tired, your body aches, and your health suffers.

1. Your old mattress equals your illegal office.

Using your bedroom as your personal in-home office, and your mattress as your giant rolling office chair is a huge no-no. Electronics and work related activity creates an atmosphere not conducive to relaxation, quality time with your partner, and most of all… sleeping.  The bright unnatural lights and physical and mental activity create constant brain stimulation, this does not in any way help set-up for a peaceful night of relaxation and rest.

At the end of the day, your mattress is an important part of your every single night.  It is beyond important but imperative.  It needs to be thought of as another consistent relationship in your life.  Just like your work, your partner and family you hopefully spend a solid 8 hours or more a night with your mattress.  It needs to be one of quality, consistency, and competency individual to you and your needs.  The financial pains and headache mattress shopping can bring will all well be worth it every morning you wake up feeling refreshed and healthy.

Sleep easy, my pretties.

Average smartphone use has climbed so high that, as Vox reported in December 2020, when major tech companies like Facebook and Google tried to implement services to moderate daily use by their customers, the efforts were unsuccessful. If even the very entities that stand to profit from constant online engagement admit there is a problem, make efforts to correct it, and fail, then it seems likely that the problem isn’t going to at least endure if not exacerbate. So let’s try to get a more solid understanding of the nature of the harm excessive access to the internet through mobile phones is causing us.

We’re not talking about the social or psychological harm of phone addiction. We’re not even talking specifically about disrupted sleep patterns. We’re going to go body part by body part, describing the damage overuse of the mobile device does over time. As the old saying goes, let’s start from the top.

10. Pineal Gland

While the constant access to updates is well-known to have negative effects on a users’ ability to relax and fall asleep, many phones have more direct negative physical effects. The blue light that is the default on a smartphone screen mimics the color temperature of sunlight, and thus it subconsciously tells the pineal gland that the user is in daytime conditions, which blocks the flow of melatonin that induces a sleep state. Even for many people who can get the sleep needed anyway disrupting the chemical flow can induce tiredness during the day.

On the bright side, if you’ll pardon the expression, tests showed that very effective countermeasures exist for those who can’t kick the habit of using their smartphone in bed. An evaluation published by the American Academy of Optometry in March 2020 found that switching a smartphone to night mode for bedtime usage lowered the potency of the effects by about 93%. Additionally, an article on the subject by Cleveland Clinic reported that not using the smartphone as little as 30 minutes before bedtime offset the effects.

9. Temporal Lobes

Temporal lobes are involved in the control of involuntary biological processes, most notably the beating of a heart. Among epileptics, they are the portions of the brain that are malfunctioning during blackouts, chest pains, and other symptoms of a seizure. According to Economic Times, prolonged use of smartphones has been found to aggravate seizures. This is no trivial matter for epileptics, as there is roughly an annual 0.1% chance of becoming victim to Sudden Unexpected Death in Epilepsy, and that’s among those that are otherwise healthy.

Fortunately, according to A. K. Sahani, the senior consultant for the Indian Spinal Injuries Center, keeping phone calls under an hour’s length significantly reduces the deleterious effects. Even for those who need to use the device for that long, using earpieces instead of holding the phone up to the head is a largely effective means of preventing the negative effects to the autonomous systems. For those who are not epileptic and think this is not advice that matters for them, bear in mind that a 2016 study reported by the Iranian Journal of Basic Medical Sciences found evidence that prolonged exposure left mice more vulnerable to seizures, indicated even those who are not diagnosed epileptics can suffer similar damage.

8. Eyes

It turns out evidence indicates that the blue light of smartphone screens doesn’t only negatively affect the pineal gland, as you’ll soon see. Or perhaps as you may not see. In 2018, researchers at the University of Toledo tested exposing cells to the shorter wavelengths of blue light. The results were that those infused with retinal, a chemical released by the eyes, suffered damage that tissue without retinol in it did not. This could be disastrous for photoreceptor cells in the eyes, as damage to those cells is permanent.

The sort of damage it is postulated that smartphone blue light worsens is called macular degeneration. This condition is most prevalent among people above the age of 60. So for our older viewers that are hesitant to begin using a mobile device, Dr. Ajith Karunarathne just gave you a great medical excuse.

7. Ears

No it’s no surprise that pumping loud music directly into your ear canals is at the worst extremely risky for the quality of one’s hearing. However research from the University of Arkansas for Medical Services found that even if the volume is kept low, it can still damage hearing. As Dr. Allison Woodall explained, using a phone for over an hour a day can lessen a listener’s ability to hear sounds between 2,000 and 8,000 hertz (which includes a wide range of human speech) because of the electromagnetic waves emitted by the device rather than the strict sound waves.

As with other entries, there are solutions to those whose lifestyles make it infeasible to just decide to use a smartphone less. Woodall highly recommended the use of the hands free option or speaker phone to get the device away from the ear. Additionally, in 2021 Reuters reported that studies found that wireless bluetooth ear pieces lowered the electromagnetic exposure by as much as 1,000%, and that AirPods were an equally safe solution.

6. Teeth and Jaw

If the thought of a smartphone habit is making you anxious enough to grind your teeth, research by Tel Aviv University has given solid evidence that many if not most heavy smartphone users can relate. Tel Aviv University’s School of Dental Medicine was in an especially good position to test the hypothesis. There are many ultraorthodox Jews in Israel who use more basic cell phones without access to social media platforms, so it was a relatively easy matter to acquire a substantial study group of non-Smartphone users.

A study of 600 participants found that among smartphone users, 45% reported that they suffered from teeth grinding, compared to 14% among the orthodox, a more than 200% higher rate. Additionally, 29% of smartphone users reported that it was severe enough that they felt noticeable jaw pain while among the orthodox it was only 14%. In many cases, the harm was severe enough that joint damage occured in the jaw.

5. Neck

There was a particularly cutting meme in 2016 which portrayed a player of Pokemon Go suffering from a grotesquely elongated neck that a Pokemon rode on. Turns out that was probably more cruelly accurate than the artist intended. As reported by the Chartered Society of Physiotherapy in 2014, when smartphone users look down to type out a text message, the forward tilt of their head shifts more strain to the top vertebrae. We’re talking substantially more strain here. A model published by The Guardian went into detail on the effects: Tilting down 15° adds 125% more strain then holding a head level. At 30°, it’s about 233% more. By a 60° tilt it is up by 400%. The degree of pain, numbness, and general dislocation this can lead to has been known to require surgery to correct. A study published by the International Journal of Environmental Research and Public Health found problems have set in for heavy users as early as adolescence or even in childhood.

Solutions for this have included switching more to old-fashioned audio calls over texting. Of course, we saw in entries such as #7 that holding the phone up to the user’s ear can have some negative effects too. For those who’d rather continue texting, there are a number of exercises that can be used to treat the effects. For example there’s “chest opening,” which involves clasping the hands behind the head and squeezing shoulder blades back for 10 to 20 seconds. There are also multiple yoga stretches that are productive treatments. It could be argued, though, that all this will use up the time that a smartphone user saves by texting. Still, better than pain or surgery.

4. Heart

It’s nothing new that mobile devices are not good for heart health, considering federally funded research into the subject began in 2010. The study surprisingly found that younger members of the control group tended to suffer the most extreme cases of heart arrhythmia, palpitations, flutters, and other conditions. The effects of smartphones have been so pronounced that they’ve been put forward that they have changed both the most common day of the week and the time of day for cardiac arrests.

We do wish to caution that the findings indicate that the effects are from behavioral changes instead of due to the electrical processes of the devices. A 2012 study by Annals of Medical and Health Science Research found that the electromagnetic processes of a smartphone do not significantly affect hearts. However, the US Food and Drug Administration recommends that anyone with a pacemaker keep it at least six inches from their smartphone at all times.

3. Elbow

As if Text Neck weren’t enough, by 2009 “Cell Phone Elbow” had become a commonly used nickname for the discomforts of heavy smartphone use. It was actually a rebranding of Cubital Tunnel Syndrome, which had been recorded in medical journals since at least 1958. How it works, or fails to work depending on how you look at it, is that holding up a smartphone for a prolonged period pinches the ulnar nerve in the forearm and at times moves it out of the proper position and into a place where it can be damaged. It’s similar to carpal tunnel syndrome though much less common before people began propping the arms up on their elbows to watch their smartphone screens at night.

Once again, for those who want to avoid surgical procedure Cubital Tunnel Release, exercises are there to come to the rescue. Popular Science suggests putting arm curls and overhead presses into a workout routine as a preventative measure. User who have already noticed mild pain or numbness should begin to heavily massage their forearm and outer forearm.

2. Wrist

If you were worried that people are becoming so weak that just the effort exerted to hold up a phone is becoming an issue for us, it’s not the act of holding up the phone that’s the problem. It’s swiping the fingers that we should worry about. The unusual ways that fingers move to scroll across sites on smartphones have been linked to conditions such as tendonitis, chronic pain, and even loss of use of the index finger and thumb, a malady nicknamed “trigger finger.” An October 2021 Washington Post article on the subject boosted the phrase “smartphone pinkie” for the impact of excessive phone use on the digits, but fortunately that doesn’t seem to have caught on.

John Hopkins University’s orthopedic surgeon Duc Nguyen’s suggested treatments included often changing position on how the smartphone was held, using handheld devices, or getting a pop socket to distribute the weight more evenly across the fingers. It should be mentioned, though, that Ventura Orthopedics surgeon Josh Gluck told Slate magazine that the fingers are not connected to the ulnar nerve, so looking out for the fingers and wrist doesn’t risk causing  more trouble with Cell Phone Elbow.

1. Sciatic Nerve

And now we have reached the end, both of the list and the rear. See, the sciatic nerve is the longest nerve in the human body, and it runs from the lower spine down to the foot. Placing smartphones in back pants pockets has been determined to put unnatural pressure on the sciatic nerve, like a more direct version of the discomfort heavy smartphone use places on the ulnar nerve.

If you’re wondering why smartphones would cause this problem and not something like, say, a gun belt or a tool belt, well, those actually do as well. In all cases, a simple and effective treatment seems to be moving the problem device to the front. For those who are worried that a front pocket smartphone presents a risk to the sperm, don’t. In 2014 the University of Utah Health Hospitals and Clinics reported that mobile devices had at most an 8% effect on sperm counts, meaning more than enough healthy sperm that avoiding sciatic nerve problems were worth the tradeoff.
