What was discovered in 1940?

In 1940, a group of teenage boys stumbled upon a cave filled with prehistoric artworks. The boys were so moved by the art that they camped outside the cave for a week just to protect the paintings inside. Eventually, they told a trusted teacher about their find—which turned out to be one of the most important discoveries in the history of art. The extensive paintings of bulls, deer, and other prehistoric animals are estimated to be about 17,000 years old and demonstrate that Stone Age peoples grasped the complexity of figurative art.

What have scientists discovered about the evolution of humans?

In the last couple of centuries, scientists have uncovered ancient fossils, prehistoric artwork, and other clues to the evolutionary origins of humankind. Here are nine of the most revealing discoveries that have changed our understanding of our early ancestors—and ourselves.

Why did geneticists sequence mitochondrial DNA?

Because the fragments were too small to identify, geneticists sequenced their mitochondrial DNA. The fossils proved to be from a previously unknown human ancestor—one that branched off from anatomically modern humans and Neanderthals about 1 million years ago.

When was Homo erectus discovered?

Dutch anatomist Eugène Dubois discovered the first Homo erectus fossils in Indonesia in 1891. At the same time, he found an engraved mussel shell that then remained in a museum drawer for more than a century. In a 2014 study in Nature, researchers dated the engraved lines on the shell to between 430,000 and 540,000 years ago. The findings suggested that H. erectus was capable of sophisticated and complex ideas as well as abstract thought.

Where were the Denisovans found?

In a cave deep within the Altai mountains near the Russia-Kazakhstan border, Russian archaeologist Michael Shunkov discovered fossils of an unknown hominin in 2008. Because the fragments were too small to identify, geneticists sequenced their mitochondrial DNA. The fossils proved to be from a previously unknown human ancestor—one that branched off from anatomically modern humans and Neanderthals about 1 million years ago. According to the study announcing the finding in Nature, the mDNA profile showed the Denisovans—named after the cave where the fossils were discovered—migrated out of Africa separately from early Neanderthals and Homo sapiens.

How many figures are there in the caves in Chiribiquete National Park?

Spanning eight miles in southern Colombia, caves in Chiribiquete National Park are covered in vast prehistoric paintings.

Newsletter

From fire to metals and fossil fuel, numerous key discoveries have served to advance human civilization over thousands of years. Humans have a long history of uncovering earthen materials, natural phenomena, chemical reactions and processes — then building on those findings to further scientific progress.

Earth in Motion

Mathematician and astronomer Nicolaus Copernicus discovered that everything in the universe revolved around the sun, rather than the Earth. Up until his discovery, it was believed that the Earth was the center of the universe, with stars, planets and the sun all revolving around our planet.

Electricity

It’s a common misconception that Ben Franklin discovered electricity with his famous kite experiment. Actually, what he did in his 1752 experiment was use a key and a kite to demonstrate that lightening is a form of electricity. Another myth is that Franklin was struck by lightning. He wasn’t, but the kite was charged by the storm.

Germ Theory

Louis Pasteur discovered that living microorganisms caused fermentation, which could make milk and wine turn sour. From there, his experiments revealed that these microbes could be destroyed by heating them — a process we now know as pasteurization.

Gravity

No, Isaac Newton didn’t really get hit on the head with an apple, as far as we know. But seeing an apple fall from a tree did spark an idea that would lead the mathematician and physicist to discover gravity at the age of just 23.

What did Gutenberg do to the world?

With his printing press, books no longer were just treasures of the rich; they were shared amongst the masses. Gutenberg’s contribution to science makes him a crucial figure in the field of education, as well. His printing press helped educate the masses, and we are better as a society for it.

When was the wheel invented?

You have to wonder how things got done prior to its invention. The history of the wheel begins in 3500 BC. Aside from the very obvious benefits of moving larger objects and transporting goods and people from Point A to Point B, many of today’s technologies would not been developed if it weren’t for the wheel.

Who invented the internal combustion engine?

Image: Cars and Their Revolution. Some credit Christian Huygens with the invention of the internal combustion engine in 1680. Others say J.J. Etienne deserves the credit – he used gasoline to power his in 1859. More accurately, the internal combustion engine is the work of many men over many years.

How many volumes of information were produced before the end of the century?

Possibly 200 million volumes had been produced before the end of the century. The printing press introduced us to the era of mass communication. Information could be spread all over the world, and people used this to spread ideas, and information that normally the average person would have no access to.

Why is Isaac Newton considered to be the greatest scientist in the world?

Isaac Newton is considered to be one of the greatest scientists in history because of his many great contributions to science.

What was the greatest discovery of the Neolithic period?

The wheel was the greatest discovery of the neolithic period. It allowed humans to transport heavy loads across far distances with ease. Wheels transformed our world beyond recognition. In modern times you see them everywhere cars, planes, even ships.

Why did early civilizations use gold?

Metalworking. Early civilisations likely used gold before any other metal because it’s only metal that occurs naturally in it’s pure form. People likely just found nuggets of gold in the ground. Other metals can be found from meteors that hit the ground but these are rare.

What are the most important discoveries made by our ancestors?

These seven discoveries made by our ancestors at different times in the past underpin all subsequent major human discoveries and inventions. Stone tools allowed us to make new wooden tools, and both led to the harvesting of new food resources, while fire enabled us to cook them. More varied and nutritious food fired up our ancestors’ brains, leading to new inventions for survival. Baby slings allowed ancient people to move great distances much more easily, eventually leading to long journeys out of Africa by both archaic and modern human groups. Watercraft, at first basic rafts but later more complex vessels, allowed early humans to travel across water as well as land, giving access to new resources such as deep water fish as well as enabling fast journeys over great distances, such as the first human voyages to Australia. Watercraft as transport eventually led to the wheel, trains, motor vehicles and aircraft.

When did humans first travel across open water?

The best early evidence of a modern human voyage across large stretches of open water is the colonisation of Australia at least 50,000 years ago , navigating 50–90 km stretches of water where land could not be seen. Credit: Jamie Tufrey
