The Evolution of Human Technology

Technology began with the conversion of natural resources into simple tools. In the early civilizations, humans have used simple tools like hammer, axes and other simple tools by combining some wood and rock. Then, the discovery of metal fueled revolution in the way humans live. Until today, technology is continually evolving, providing us a better way of enjoying life and doing the things that we’ve got to do. There are significant events in the evolution of human technology that can make you wow. We’ll start with the very basic.

Paleolithic Technology

The use of tools of early humans is a process of discovery and of evolution. The use of stone tools has begun long before the emergence of Homo sapiens around 200,000 years ago. The earliest known time of stone tool making dates back to 2.5 million years ago. Wow, that’s really so long.

Then, the discovery and use of fire is defined as the turning point in the technological evolution of humanity. Evidence has it that the domesticated use of fire occurred a million years Before Common Era. It allowed early humans to cook food, thus allowing better digestibility and improving its nutritional value.

It’s also within this period that humanity began to start using clothing and build shelter. As early as 380,000 BC, humans created temporary wood huts and with the help of clothing created from hides and fur of hunted animals, humans expanded into colder regions.

Neolithic Technology

The Neolithic period, aka “The New Stone Age” has fueled a new era for human’s technological evolution. The discovery of agriculture allowed feeding of a larger population. Soon, metal tools began to be discovered and used. The creation and use of furnace and bellows has given us the ability to forge and smelt native metals.

Humans also learned to harness other forms of energy. Wind power is used via sailboat. Early Egyptians used the power of the Nile River to irrigate their lands as well as the early people of Mesopotamia and Sumeria also learned to use Tigris and Euphrates.

It was also in this time when wheels were invented. With its invention, revolution in the field of transportation, war and pottery production started. The use of wheels as a transformer of energy through water wheels, windmills and even treadmills revolutionized the application of nonhuman power sources.

Medieval and Modern Technology

Technological advancement and evolution seems to speed up as times pass by, probably because we use these newfound technological inventions and discoveries to invent and discover newer ones. Medieval technology allowed the use of levers, screw and pulleys also called the simple machines. They were combined to create complex tools like clock, windmills and wheelbarrows.

The evolution of technology continues until it allowed us to communicate with other people even they’re far away. We are able to gather information using only our fingertips. And one of the latest is that we are able to send a machine to land on a comet.

Historic First Landing on a Comet

It seems so impossible before, many attempts were made, and all was a failure. The spacecraft crashes into the comet or sometimes it loses it way resulting in a failed mission. However, history changed when humanity successfully landed on a comet for the first time. Well, not actually a human but human-operated spaces probe.

After a seven-hour period of waiting and intensity, the signal broke out bringing the European Space Agency’s mission control in Darmstadt on a state of victory. They’ve achieved a seemingly impossible feat of landing a robotic spacecraft on a comet. This is the first time in history and it’s a great achievement.

However, the seemingly soft landing isn’t what it seems to be. They say that Philae may have bounced off rather than being gently settled at once on the surface of the comet. The comet, with a rather odd name, 67P, has a very weak gravity and the spacecraft was supposed to shoot harpoons into the comet to fix the craft on the surface. However, they failed to fire and Philae is not firmly secure.

“So maybe we didn’t land once — we landed twice,” Philae lander manager Stephan Ulamec said. “Did we land in a soft sandbox or is there something else happening? We don’t fully understand what happened.”

The Discovery of the Century? Probably.

Rosseta’s comet revealed its first secrets. Scientists believe that the carbon compound found on the comet could explain how life thrived on Earth some 3.8 billion years ago.

“Rosetta is trying to answer the very big questions about the history of our solar system,” Matt Taylor, ESA Rosetta project scientist, said in the article on the ESA website. “What were the conditions like at its infancy and how did it evolve? What role did comets play in this evolution? How do comets work?”

“Our ambitious Rosetta mission has secured a place in the history books: not only is it the first to rendezvous with and orbit a comet, but it is now also the first to deliver a lander to a comet’s surface,” noted Jean-Jacques Dordain, ESA’s Director General.

The Rosetta mission intends to open the secrets of comets produced using antiquated material that originates before the birth of the earth’s planetary group. In the information Rosetta and Philae gather, analysts would like to take in more of how the earth’s planetary group formed and how comets carried water and complex organics to the planets, setting up the stage for life on Earth.

As our technology goes more and more advanced, we can be rest assured that the discovery of Earth’s origin will come closer and closer within the coming years.
