The Most Important Inventions in the Last 20,000 Years That Have Changed Human Life

The top inventions that changed human life, ranging from computers to the most basic necessities. Check out which ones made a difference in YOUR life!


The Wheel


 Look around you…the wheel, or some variation of its design, may be found everywhere. Despite this, we rarely consider it! It’s something we take for granted, but ancient people didn’t. According to historians, the wheel was not invented until a very late stage in the development of humanity.


 However, the historical record suggests that humans had already mastered agriculture, animal domestication, and the principles of complex architecture before inventing the wheel.


The wheel was not invented until the Bronze Age when tools made it possible to chisel wood in intricate and exact designs.


The shaping and creation of something like the wheel would have been beyond ancient man’s practical capabilities prior to it.


Obviously, after the wheel had spread over the world, it revolutionized travel and transportation… particularly in terms of trade.


The wheel was still used for farming and construction even in places where traveling by horse or camel was more efficient. Without the wheel, our modern world would be unable to function.


The Nail


The Nails

Nails date back to ancient history, although they seem simple today. In 3400 BC, the ancient Egyptians are thought to have discovered how to construct forged nails.


These arm fasteners were made by hammering the tips of square iron blocks to a point, allowing them to penetrate the wood.


Prior to the invention of nails, humans were forced to use rope straps to hold wooden structures together or carve the wood into complicated, interlocking patterns that allowed the structure to support itself.


However, with the help of the nail, more and larger structures were made possible. For a long time, nails were considered to be somewhat expensive pieces of hardware.

Cut nails were introduced in 1821, allowing nails to be produced from sheets of iron, but the greatest change in nail production occurred in 1875 when nails made of wire were created.


In today’s world, almost everybody in the developed world can afford low-cost, high-quality nails.

Without the nail, which was eventually developed to become the screw, society’s buildings and houses would almost definitely look very different, and many designs would not be able to stand up to the test of time today.


Domestication Animals


Domestication Animals

We’ve been domesticating and taming animals for a long time. Livestock production today covers a large economic sector in our global economy. Pets and animal helpers are also available to modern man to assist and comfort him in his daily life.


All of this began 20,000 years ago, during the last Ice Age. During this time, three species fought for control of the earth’s frozen plains and forests.


One of these species was fast and powerful, and it was great at hunting down and exhausting prey…but it wasn’t very good at killing it.


The next species was great at using tools to kill prey safely…but not so good at running it down and tiring it. The final group was solitary, but they utilized tools to ensure the deaths of their prey, just like the second group.


 So, let’s take a look at it. The first group consisted of ancient wolves, the second of our human ancestors, and the third of our ancient cousins, the Neanderthals. Our forefathers and the ancient earth’s wolves paired up at some point in the past.


Our near relatives, the neanderthals, were outmatched and eventually became extinct as a result of their creation of a team that was so strong and effective.


Continue ahead, and we’ve now tamed cows, bunnies, horses, cats, and more! We might not have survived as a species if we hadn’t acquired the ability to work collaboratively with other animals! But we did, and we owed it to our animal companions to thank them!

Humanity has fought both nature and each other since the beginning of time. However, for hundreds of thousands of years, we were unable to fight sickness, which was possibly the single most devastating killer of our species!


Prior to the introduction of immunization, the only way to become immune to a disease was to contract it first and then survive it.


Edward Jenner began experimenting with inoculating individuals against smallpox by infecting them with cowpox, a far less fatal infection, in 1798, which was quite a perilous thing to do back when medicine was in its infancy.


Smallpox, measles, polio, and other violent illnesses have all but been eradicated in recent times! Immunizations are to thank for this. Most of us may now live full, happy lives without fear of death from microscopic invaders hurting our bodies, thanks to man’s breakthroughs in battling viruses.

Antibiotics are antibiotics that are used to treat infections and bacterial invasion. Antibiotics, along with immunizations, revolutionized twentieth-century medicine and have since completely changed how we treat sick people.


Antibiotics have nearly eradicated bacterial illnesses such as tuberculosis in the developed world, and they have the potential to kill microorganisms worldwide if given enough time.


Medicine was hardly a “black-and-white” scientific topic before the twentieth century. It was steeped in folklore and superstition, rather than science.


The discovery of germs, as well as our capacity to combat them, has essentially allowed us to make significant progress in the fight against the disease. The first scientific study on the topic of fighting germs was published in 1897.


Sir Alexander Fleming

Sir Alexander Fleming discovered the use of penicillin in fighting against and killing previously deadly bacteria in 1928.


In the modern era, we’ve continued to improve our understanding of antibacterial therapy and develop ever-stronger strains.


However, many experts now believe that the microorganisms on this planet are becoming resistant to the treatments we’ve produced to fight them!


Antibiotics have helped us in leaps and bounds toward a brighter future in a world where our infrastructure, economy, and entire societal structure are built on longevity and medical care.


But what if, after only a few hundred years, we lose the ability to use these same drugs? What are your thoughts? Please tell me in the comments section below.

The invention of the train changed the Western world in both Europe and America. Travel became more accessible, and the concept of how far one could travel and how much one might see in a lifetime was turned upside down!


Cities that were formerly thousands of miles apart were suddenly only a day or two away, owing to railroads.


This transport revolution sparked national, and then international, economies and trade. Railroads allowed communities to rise and collapse, and they metaphorically held the life of numerous cities in their palms.


Without railroads, America would never have risen to its current levels of dominance, and many countries’ industrialization would have progressed much more slowly!


Despite the advent of cheap cars and air travel, railways continue to play an important role in transporting people and goods throughout the world today. In the past, the world’s railroads conquered the majority of the world’s developed countries.



 The Printing Press


The Printing press

All writing had to be done by hand before the introduction of modern printing processes. Any existing copies of books had to be transcribed by hand. The written word became a highly expensive luxury as a result of this meticulous and time-consuming process.


Because the combined knowledge of the human race was contained behind books that only the elites could access, a genuine understanding of religion, science, and mathematics were all reserved for the elites.



Johannes Gutenberg

When Johannes Gutenberg, a German goldsmith, created the printing press, everything changed! Because of this man’s invention, knowledge could now be made available cheaply and quickly…not just to the wealthy, but also to the middle class.


The average level of education would steadily climb to impressive levels throughout time. The modern workforce is more capable and educated than previous generations, and the average citizen of a first-world country has lived their entire lives benefiting from freely available information!





The Farming

Our ancestors lived in harmony with nature about 10,000 years ago, hunting and killing for their food as every other predator in the world had done for millions of years.


We did exceptionally well for ourselves. However, our numbers were small, and we had yet to achieve our goal of becoming the planet’s Masters.


Then we learned that a single grouping of seeds could feed us while requiring far less area and effort than hunting and feeding a family. Our ancestors were able to establish villages, towns, empires, and even spread across the globe thanks to agriculture!


With more people living thanks to the discovery of farming, there were more people to talk, think, and invent in a race to dominate this planet and become the primary custodians of our world.


Agriculture, in a way, set the groundwork for every other technical progress we’ve made since the invention of tools and the construction of simple huts!

The fire was our only source of warmth and light until the invention of the light bulb and modern heating. Millions of years ago, fire was discovered, allowing humanity to travel across the globe…even into the harshest of environments.


Our ancestors were able to work late into the night and into the early hours of the morning because of the protection, safety, and comfort given by fire.


They could even use fire to defend themselves from harmful animals! Fire is the most basic invention on this list, yet it is also a major necessity in life.



The Computer


The Computers

The invention of a device that tracked the astrological movements of stars can be traced back to ancient Greece, where the first clock or the computer was invented.


Clockwork devices were the most popular in the 18th century. Then, in the late nineteenth century, Western academia began to construct the first advanced analog computers.


However, it wasn’t until the late twentieth century that we realized exactly how far machines might be pushed in terms of number processing and programming. We are now in the twenty-first century, and computers have connected the world!


The Internet is the largest repository of human knowledge ever assembled, and information travels at the speed of electricity.


Before it was ransacked, it was larger than the libraries of ancient Babylon and even Alexandria. With the click of a few buttons, researchers, scientists, and even the typical layperson may learn anything, communicate with anyone, and view practically everything.


The invention of the digital computer has pushed the human race into a period of unprecedented rapid advancement! What are your thoughts on these innovations?
