What Will Humans Look Like In 100 Years? – Evolution

Future Human Evolution

The speed of evolution the speed of human evolution increased quite dramatically in the last 250 years. There are a lot of different variations in human genes and also in human bodies across various generations. For example, lactose intolerance is present in specific populations but not in others. And it is related to a specific gene in a certain bacteria.

The main thing that speeds up evolution is gene flow. The wider the gene pool, the more variety achieves. About 100 years, the humans living on planet earth might acquire more features that they currently don’t have. Some of them might be useful some of them might be useless.

As remarkable as the human brain is, it does have many limitations. Humans have limited intelligence, limited working memory, and a very bland sensory experience compared to other animals. If scientists could ever make the human mind substrate independent, they would perceive the world in ways.

Dr. Randall Cohn created the carbon copies foundation. It’s a nonprofit organization researching just that. With the attention goal of creating synthetic people, Ecoles substrate independent minds pork since for short. Let’s see the future human evolution timeline.

What will humans look like in 100 years?

What will it be like to be human in 100 years? The futurist Ray Kurzweil made a fantastic prediction a few years ago. He said that advances in computer processing, artificial intelligence, robotics, genetic engineering would all lead to a transformative moment in our history as a species. It would happen around 2045, and things would start changing so quickly that it would be impossible to define the present.

Moreover, humans would use these technologies to become trans-human, maybe becoming cyborgs, genetically engineered beings. The important thing is the human would evolve millions of times faster than the process of natural selection would allow. What would it be like in 2116?

By 2045 standards, the people of today will seem a little primitive, maybe a bit quaint. But in 2116, that’s a different story. By that time, it’ll be unheard of for a person not to have access to whatever is the equivalent of the internet. You could communicate with anyone in the world or tap into the massive amounts of online knowledge, the idealists say. This will lead to an unprecedented era of peace. Here are some evolutionary changes of humans in the future.

Smaller brains

Human beings are pretty brilliant compared to every other species on earth. Surprisingly, the human brain has spent thousands of years shrinking rather than growing. For millions of years, the brains of human beings grew and grew. But for the last 20 thousand years, it has been gradually shrinking.

In fact, by evolutionary standards, human brains have shrunk by the size of a tennis ball. But another point is that brains are becoming more efficient. It allows human brains to focus more on things like communication. With technology improving and populations growing, there’s no reason to think this trend will be reversed any time soon.

  • A smaller brain works more efficiently than a larger one because the signals firing around it have a shorter distance to travel.

There’s also a series of smaller brains to make human-less aggressive, work together, and solve problems in peace and harmony.

Smaller teeth

There is genuinely a theory that humans will one day have beaks. In 2013 Dr. Fraser from the University of Sheffield found evolutionary similarities between human teeth and the beak. The pufferfish used to have individual teeth, but they eventually fused into a single hard beak. And Dr. Fraser predicts that ours will do the same. On the plus side, Fraser claims a beak will be more robust and practical than teeth because they can’t chip or fall out.

Wisdom teeth are used to help humans to chew food better. Due to various dietary changes, human faces decreased in size, and so mouths got smaller. And there was not enough space to have wisdom teeth in mouths anymore. In the last few decades, more and more babies are born without wisdom teeth.

Body hair vanish

Scientists think that eventually, a high chance body hair will die out from the human race within 100 years. The primitive man and a thick carpet layer of body hair protect his skin from the impact of heat and cold.

  • Humans start to evolve, and thick body hair grew thinner.

When humans get too hot, they sweat, and thick body hair was a problem for that. It would become matted and stop from being able to cool down.

Eyes evolution

The big eyes will be vital for future humans to be able to see in low-light environments. This is only one way humans might adapt in the future. So eyes will become huge and blink sideways to protect from cosmic rays. That will develop the low-light vision to be able to survive in dimmer environments.

Eyelid: Many living organisms have a third eyelid, also known as a Nyssa tating membrane. This eyelid helps provide additional protection to the eyes. It also keeps the eyes hydrated. Humans have a tiny version of this in the corner of their eyes. Modern research has discovered that because the Nyssa membrane has lost its purpose in the human anatomy. It is why it too is set to soon disappear entirely in the next 100 years.

Muscle evolution

Muscles are great, but modern humans have no rule need for that kind of strength. Evolution agrees because humans have been growing gradually weaker. Humans whose genes favored smarts over squats were more successful, meaning they bred more. Over millions of years, this has led to humans with great minds but relatively little muscle.

  • With technology increasingly available to perform most manual labor, muscles will become more and more useless and brains more and more important.

Iris muscle: The plant iris muscle is small in the calf of the leg, which lies next to two bigger muscles called the soleus and gastrocnemius muscle. It plays a small role in helping us walk and flex our toes. It’s already been dubbed as a useless muscle because it doesn’t have a significant contribution alone.

Erector pili muscles: Goosebumps are the result of the functioning of the erector pili muscles. These tiny muscles are located at the end of each hair follicle. When the human body is exposed to extreme cold, the erector pili muscles contract to generate heat. This causes the bumps to form on the skin’s surface and leaves the body hair looking like it’s standing up. In the past, these muscles are puff up in a threatening situation to seem larger and more intimidating to the enemy. This function is now redundant, and therefore, the erector pili muscles look like they are set to soon disappear within hundred years.

Subclavius muscle: The subclavius muscle is a tiny muscle situated between the collarbone and the start of the first rib. It functions to stabilize the collarbone while moving the arm and shoulders. The primary purpose of this muscle is to create body stabilization while walking on all fours. As we no longer walk using all limbs, the function of the subclavius muscle is pretty redundant. It makes it pretty much a reality that this muscle might soon fall off the biological construct of the human body.

Palmaris longus muscle: The palmaris longus is a forearm muscle that extends between the elbow and the palm. In the past, this muscle helped our ancestors grab a firm hold while climbing rocks and trees. As humans live relatively more comfortably now, the palmaris longus muscle offers no real purpose to justify its existence in the body. Statistics show that a large number of people are being born without this muscle atonia. It is a clear indication that evolution has deemed this muscle fit for extinction.

Ear & Nose evolution

Darwin’s tubercle is a set of cartilage and skin that protrude towards the top half of the year. While most people do not have it in sum, the protrusion is very evident. Centuries ago, this point in the year was thought to help amplify sound waves received by the human ear. Back then, the man was a hunter, and these parts of the body had a specific purpose. However, with the evolution of modern life, man no longer hunts for a living, and anatomical features such as Darwin’s tubercle will soon cease to exist.

One day humans might look a lot more similar than they do today. It’s truly fascinating to think that eventually, ancestors could have come from anywhere in the world. The extrinsic ear muscles are three muscles called the anterior, superior, and posterior in the outer ear. Despite their long and complex-sounding names, these muscles aren’t that useful. Most mammals have the same muscular makeup in their ears. So the extrinsic muscles aren’t a body feature.

  • Thousands of years ago, they were helpful for communication purposes, but now they are useless. So after 100 years later, they will disappear.

Paranasal sinuses disappear: Paranasal sinuses may have a few good uses. Many people think that they’ll eventually disappear because they can cause a lot of problems. Researchers believe that they have evolved to strengthen the skull, but that’s never been confirmed. But the most exciting part of the paranasal sinuses is that they work to control voice which is why two people have no entirely100% identical voice. So there’s a chance these sinuses could have disappeared.

No appendix

The appendix is a thin tube located at the junction of the small intestine near the large intestine in the past. This organ played an essential role in digestion. However, at present, it has no clearly defined role in the human body. If the appendix is removed, digestion continues with no impact. This is why scientists believe that an entire race of people will be born without the appendix soon.

Fewer toes

Toes are entirely pointless. When humans used to crawl, climb, and shuffle, about the fifth toe was vital in helping to move. The toe has spent millions of years slowly shrinking into the tiny stub it currently is. Evolutionary scientists expect humans will evolve into four-toed creatures within 500,000 years.

Grow taller

Society has always seemed to favor the vertically inclined. We will impose height requirements for specific activities and careers like riding a roller coaster or waterslide. Most Connecticut believes that good childhood nutrition is the reason we’re taller than our ancestors.

  • Over the last 100 years, the size of the modern human has increased about four inches.

So as long as our children remain well-fed human species will continue to grow taller. Females, on the other hand, will be shorter and fatter.

Bones evolution

Some people are born with strange bones in their feet, and this feature seems to be also disappearing with time. Another example is a very strange bone behind the knees that certain people have known as a fibula. This is microevolution where certain features become more prevalent and possibly even become dominant. Even if they don’t have any advantage, some features seem to have disappeared entirely in the last few decades.

Another recently discovered and analyzed feature with many different people is a strange artery that some of us have and some don’t. The unusual artery in the forearms that’s known as the median artery. This peculiar feature normally is only present in fetuses. Then it disappears completely when the person is born. There’s a problem with another artery in the body, but the actual reasons are unknown naturally.

  • The scientists in the study believe that in the next 100 years, it might become the most prominent feature across all humans.

The tail bone: The tail bone marks the end of the spine. In primitive times it marked the beginning of the tail in the human ancestors. At the same as monkeys have now. However, as time passed by, the human race evolved to exist without the tail. The tail bone thus became a redundant part of the human anatomy. While the tail bone still helped support specific pelvic muscles, its primary function is to start a tail no longer holds. This is why scientists feel that the human body will soon drop off the tail bone and learn to survive without it.

Cervical rib: Cervical rib, also known as a neck rib. The cervical rib is an extra rib that some people are born with at present. It has no clearly defined function in the human body. The cervical rib can cause pain and discomfort. The cervical rib may occur on one side of the body or exist as a pair in people who have it. Scientists are convinced that this extra rib or pair of extra ribs will soon disappear in generations.

Weaker immune system

The immune system is fighting an internal battle to kill the virus and bacteria. Experts think it might continue to get weaker and weaker. As medical science continued to improve, humans can increasingly rely on pills to guard their health.

  • This leaves the immune system may lead to its capabilities being significantly reduced over the generations.

The risk of this evolutionary direction is that it leaves us in danger of being wiped out by an unexpected pathogen. On the flip side, future humans will probably be more resistant to diabetes and heart disease.

Due to over-sanitizing lifestyles and relying so much on medications, human bodies are starting to lose the ability to fight off infections effectively. What does this mean for future generations? They’ll have a much weaker immune system, and the smallest thing could potentially kill them like a paper cut.

More attractive women

Scientists believe that women are getting more attractive. It is down to obvious things like healthier diets and basic hygiene. After all, people tend to look better when they have all their teeth.

  • Research by the University of Helsinki suggests that females are also getting genetically more attractive.

A study of over two thousand people found that more traditionally beautiful women had 16% more children. However, this same gap didn’t exist between couples with ugly and attractive men. The gorgeous women have more children. Their genes are being passed or more often bringing humanity’s average attractiveness up. So fast forward a few hundred years, and every woman would look beautiful.

Less Breed

In the future, people may not want to breed until their retirement age. According to Cadell and life history theory, the age of sexual maturity has historically increased in line with life expectancy.

  • Once their life expectancy reaches 120 in around 2050, Cadell suggests humans will become sexually active until their seventies.

The shorter, slightly plumper women in the study had more children and passed these physical traits on to their offspring. The same women tended to have kids earlier in life and lower blood pressure and cholesterol. The effects of natural selection would be slow and gradual.

Mono ethnicity

The world is getting more and more connected by the day. What will humans look like 100 years later? Scientists believe that interbreeding will eventually mix up our gene pool so much that individual races will essentially disappear. All human beings will be part of the same mono ethnicity, which scientists believe would have resembled the current appearance of Brazilians.

With increased globalization leading to more mixed-race couples, people could eventually have one ethnic group dominate the entire world. The theory is that different cultures continue to have relations. People will start losing the main distinguishing features of their ethnicity and take on characteristics from different cultures in the world.

  • Racial differences will blend until humans have the same color of skin.

However, the process of cross mixing isn’t so black and white. There are a wide variety of genes responsible for our many distinctive traits.


Many scientists believe humans will soon be able to start combining humans with machines. Professor Yuval Harari believes that within 100 years, humanity will become a species of godlike cyborgs. Elon Musk has just launched a project that aims to use computer chips to connect the human brain to an AI. There’s even a movement called transhumanism devoted to mixing humans and cybernetics.

One of the components of the theory of evolution which Darwin made known was the survival of the fittest.

  • This theory stated that the strongest of any species will always survive while any handicaps or disabilities will disappear as no other species member wanted to mate with them.

Human genetics seems to be playing less of a role, with the outcome more dependent on science and technology. In the next stage in the evolutionary scale, Bionic and prosthetic limbs are becoming more seamlessly integrated into the human body and more realistic.

Scientists predict that some people might be using specific prosthetics or voluntary amputations even if they do not necessarily require them. They will become optional surgeries viewed to make life easier or enhance specific experiences or tasks. Prosthetics will no longer become a solution or treatment for a disability but a tool for non-disabled people.

For example, hearing aids are now being developed not just for people with hearing impairments. Today hearing aids can be connected through smartphones and computers using Bluetooth. Soon hearing aids might block out background noise to allow the wearer to focus on a specific conversation. One possibility includes tracking health indicators such as blood pressure and heart rate. Technology is developing so quickly that this could be a possibility for ancestors 100 years from now. This access to technology and science will be what determines the evolution of species.

However, it’s not just in physical appearance and physical alterations that humans will change over the next 100 years. Genetic mapping mutation and altering will allow for human DNA to be controlled and eventually perfected. Scientists are talking about the development of programmable cells. These cells could be created in a lab and could be used to influence genetic coding.

  • Having control over these cells and their genetic coding could eliminate certain diseases, disorders, and other genetic or hereditary qualities.
  • Being able to program and control certain cells also gives us the potential to use certain diseases to attack other ones.

Today humans have already begun experimenting with what’s being called designer babies. This process involves genetic mutation and selecting ideal genes when implanting an embryo. This would allow for babies to be born with pre-selected qualities and genetics. This could also allow for a reduction in the manifestation of specific diseases or genetic disorders. Looking forward 100 years, this could lead to a more genetically ideal human species.

Whether living in space, living as cyborgs, or living with current bodies with ultra-developed minds, the human species is the smartest to have walked this earth.
