1.8 million years ago, the earliest signs of human activity were discovered

In a cave in South Africa, one of the earliest human activities was discovered. In the Wonderwerk Cave in the nation's Kalahari Desert, a group of geologists and archaeologists discovered proof that our predecessors were manufacturing tools and fire 1.8 million years ago.

Wonderwerk, which translates to "miracle" in Afrikaans, may contain the earliest proof of human activity ever found, according to a recent study from academics at the Hebrew University of Jerusalem and the University of Toronto.

Professor Ron Shaar of Hebrew University, the study's principal author, said, "We can now declare with confidence that our human ancestors were creating rudimentary Oldowan stone tools within the Wonderwerk Cave 1.8 million years ago.

The earliest tools, dating back to 2.6 million years ago, are Oldowan stone tools. Making a chopping tool for the Oldowan people involved chipping flakes off of one stone with another stone.

Wonderwerk is distinct from other ancient sites where tool shards have been discovered, according to Professor Shaar, because it is a cave as opposed to the open air, where sample origins are more difficult to identify and contamination is conceivable.

The researchers used the cave to date the transition from Oldowan tools to the earliest handaxes, which occurred more than a million years ago. The scientists discovered when exploring further into the cave that a purposeful usage of fire could be traced back one million years.

This is relevant because instances of early fire use frequently occur at outdoor locations where wildfires may have contributed to them. Burned bones, ash, and equipment left behind by previous fires in a cave give obvious hints as to their use.

The researchers used burial dating and paleomagnetism to assess magnetic signals from the remains buried beneath a sedimentary rock layer that was 2.5 meters thick in order to correctly date their discovery. The magnetic properties of prehistoric clay particles that accumulated on the cave floor can be used to determine the direction of the old earth's magnetic field. The scientists were able to reduce the dating range of the cave layers by using the dates of magnetic field reversals.

Another dating technique, developed by Professor Ari Matmon of Hebrew University, focused on quartz sand isotopes that "had a built-in geological clock that starts ticking when they enter a cave" and helped to support their findings. He explained that by measuring the concentrations of particular isotopes in those particles in their lab, the researchers were "able to assess the concentrations of those particles and extrapolate how long it had been since those grains of sand entered the cave."

A deeper knowledge of human evolution in Africa and the mode of life of our earliest ancestors may result from discovering the precise dates of human activity in the Wonderwerk Cave.

When The Last "Siberian Unicorn" Lived on Earth is Now Known Thanks to a Fossilized Skull

Scientists have long hypothesized that the Siberian unicorn, a long-extinct species of mammal that resembled a rhino instead of a horse, perished about 350,000 years ago.

But, a stunningly preserved skull discovered in Kazakhstan in 2016 has utterly disproved that notion. It turns out that these amazing creatures were still alive 29,000 years ago.

Sure, this proves that a unicorn existed in the actual world and walked the Earth tens of thousands of years ago, but it was quite different from the unicorn shown in your favorite children's book. (Sorry; we're also disappointed.)

The true unicorn, Elasmotherium sibiricum, was hairy, enormous, and resembled a contemporary rhino, with the exception that it wore the largest horn possible on its forehead.

The Siberian unicorn was first thought to be about 2 meters (6.6 feet) tall, 4.5 meters (14.7 feet) long, and weighed about 4 tonnes.

That resembles a woolly mammoth more than a horse. Despite its enormous size, the unicorn was presumably a grazer that largely consumed grass.

Thus, instead of picturing a short, stubby horn like those on modern rhinos, picture a fuzzy rhinoceros with one long, slender horn sticking out from its face.

The skull was discovered in Kazakhstan's Pavlodar region and was astonishingly well preserved. Using radiocarbon dating methods, researchers from Tomsk State University were able to determine that it was formed about 29,000 years ago.

They speculate that it was probably a very elderly male based on the size and condition of the skull, but the manner of death is still unknown.

How this unicorn survived so much longer than animals that went extinct hundreds of thousands of years earlier is the topic on researchers' minds.

According to one of the team members, Andrei Shpanski, "Most likely, the south of Western Siberia was a refugium, where this rhino endured the longest in relation to the rest of its range."

Another possibility is that it might go to the southern regions and stay there for a while.

Since it appears that some creatures may have survived far longer than previously thought by migrating across vast distances, the team thinks that the discovery will help researchers better understand how environmental conditions played a part in the creatures' extinction.

Given that we are in a very precarious position, knowing how the species endured for so long and perhaps what ultimately caused its extinction should help us make better decisions concerning the future of our own species.

Discovering the Majestic Guardian Colossus: A Prominent Brick and Stone Sculpture from the 16th Century

A spectacular work of art, The Appennino (Italian: Colosso Appenninico), is a 35-foot-tall sculpture that can be found in Villa Demidoff, a portion of the former Villa Medici in Pratolino, 7 miles north of Florence. The Appennino, a personification of the Apennine mountain ranges created by the Flemish artist Giambologna between 1579 and 1580, is sculpted in such a way that it looks to be on the dividing line between man and landscape, with its smooth skin blending into the rugged terrain. The Appennino also has a stalactite-made shaggy beard.

Giambologna carved a fish pond into the Appennino while it was clutching the head of a horrible beast. The Appennino is not only a sculpture; it is also a structure that has a network of grottoes that are decorated with paintings of muscular men and priceless minerals as well as shells, corals, pearls, and crystals. Two functional fountains and a room for a small orchestra are also included in The Appennino's head. Additionally, the head contained a fireplace that could be lit through the Appennino's nose and would emit smoke.

The Appennino in 1911.

The Appennino is housed in Villa Demidoff, which is 10 kilometers north of Florence at the foot of the Apennine mountain range. The Prato del Appennino, a rectangular square, is situated in front of the enormous statue. After Francesco de' Medici and his wife Bianca Capello passed away, the Villa di Pratolino deteriorated and was eventually destroyed in 1822. The Demidoff family purchased the site in 1872, and they proceeded to develop their own villa there. The Province of Florence acquired the Villa Demidoff in 1981, and it is currently accessible to the general public.

7,500 year old cursed Sialk Hills city of Iran

Sialk Hills, located in the southwestern part of Kashan city in Iran, was known among the locals as a ‘cursed city’ where people were afraid to approach. Before a severe flood led to the discovery of Sialk Hills, no one dared to approach this terrifying location.

Thanks to the flood of 1930, the story of the Sialk Hills, dating back 7500 years to the Achaemenid Period, was also revealed.

In reality, this structure is a ziggurat, a rectangular stepped tower that occasionally has a temple on top and is made primarily of clay; it is possible that calling it “hills” would not be accurate.

It is claimed to be the world’s oldest ziggurat, dating to the 3rd millennium BC, tucked away in the suburbs of the city of Kashan, in central Iran, close to Fin Garden.
