Secret History
The Nazca Lines have become world famous, showing up in paintings, movies, books and news articles. They exist on the floor of the Nazca desert in a southwestern part of Peru, near the ocean. Scientists believe the figures (approximately 700 in all) were created by the ancient Nazca people over a time period of a thousand years - 500BC to 500AD. The geoglyphs vary in size and have been categorized into two distinct categories: natural objects and geometric figures.
The natural objects include animals such as birds, camelids, or snakes. It is believed the lines were created by removing iron-oxide coated pellets to a depth of four to six inches - that left the lighter sand below in stark contrast to the surrounding area. The images vary dramatically in size, with the largest approximately 935 feet long. It is a myth that the figures on the desert floor can only be seen by aircraft (they were first "discovered" by a pilot flying over the desert in 1939). In fact, they can be seen quite easily when standing on nearby mountains or hills.
Estimates of the age of the earthwork are now radically revised as the result of a new radiocarbon analysis, suggesting that the mound is about 1,400 years older than conventionally thought. The new date of construction is estimated at approximately 321 BCE, one year after the death of Aristotle in Greece.
Signs and other interpretive material have been made obsolete virtually overnight, along with ideas about the indigenous culture responsible for the astounding artwork. A paper by an eight-member team led by archaeologist William Romain has been published in the Journal of Archaeological Science with a free-access summary available on Romain's website.

A Cherokee boy and girl stand in costume on a North Carolina reservation in 1939.
He wrote in his book "The History of the American Indians": "It is a very difficult thing to divest ourselves, not to say, other persons, of prejudices and favourite opinions, and I expect to be censured by some for opposing commonly received sentiments, or for meddling with a dispute agitated among the learned ever since the first discovery of America."
In more recent years, similar observations by Dr. Donald Panther-Yates have even met with what Yates described as "hate mail" from indigenous studies professors.
It is commonly held that Native Americans descended from Mongolians. In 2013, a study published in the journal Nature acknowledged that some ancient European ancestry is possible. The DNA from a 24,000-year-old corpse in Siberia was analyzed. It showed no resemblance to Asian populations, only to European, yet it showed a clear connection to Native Americans. But the mainstream scientific community is far from embracing the theory that Native Americans descended from ancient Middle-Eastern or Greek peoples as Yates and some others have proposed.
The Plain of Jars in the Xieng Khouang plain of Laos is one of the most enigmatic sights on Earth. The unusual site of thousands of megalithic stone jars scattered across nearly one hundred sites deep in the mountains of northern Laos has fascinated archaeologists and scientists ever since their discovery in the 1930s.
The unusual site known as the Plain of Jars is dated to the Iron Age (500 BC to 500 AD) and is made up of at least 3,000 giant stone jars up to 3 metres tall and weighing several tonnes. Most are made of sandstone but there are others made of much harder granite and limestone.
Because the jars have lip rims, it is presumed that all of them were originally covered with lids and although a few stone lids have been recorded it is more likely that the main material used was wood or ratan.

A composite image shows the facial differences between an ancient modern human with heavy brows and a large upper face and the more recent modern human who has rounder features and a much less prominent brow. The prominence of these features can be directly traced to the influence of the hormone testosterone.
Modern humans appear in the fossil record about 200,000 years ago, but it was only about 50,000 years ago that making art and advanced tools became widespread.
A new study appearing Aug. 1 in the journal Current Anthropology finds that human skulls changed in ways that indicate a lowering of testosterone levels at around the same time that culture was blossoming.
"The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at the same time that we developed a more cooperative temperament," said lead author Robert Cieri, a biology graduate student at the University of Utah who began this work as a senior at Duke University.
The study, which is based on measurements of more than 1,400 ancient and modern skulls, makes the argument that human society advanced when people started being nicer to each other, which entails having a little less testosterone in action.
Heavy brows were out, rounder heads were in, and those changes can be traced directly to testosterone levels acting on the skeleton, according to Duke anthropologist Steven Churchill, who supervised Cieri's work on a senior honors thesis that grew to become this 24-page journal article three years later.
What they can't tell from the bones is whether these humans had less testosterone in circulation, or fewer receptors for the hormone.
The research team also included Duke animal cognition researchers Brian Hare and Jingzhi Tan, who say this argument is in line with what has been established in non-human species.

The letter documents a previously unrecorded meeting between George V (left) and Sir Edward Grey (right)
A note which has remained in private hands for a century details a previously undocumented meeting between George V and his Foreign Secretary, Sir Edward Grey, on the eve of the First World War.
The King, mindful of his position as a constitutional monarch, made no public declarations about the situation in Europe in the lead-up to the conflict.
But in the newly-disclosed meeting, the King informed Sir Edward it was "absolutely essential" Britain go to war in order to prevent Germany from achieving "complete domination of this country".
When Sir Edward said the Cabinet had yet to find a justifiable reason to enter the conflict, the King replied: "You have got to find a reason, Grey."
Historians have no record of the meeting which took place at Buckingham Palace on August 2 1914, two days before Britain went to war.
It was revealed in a letter written by Sir Cecil Graves, Sir Edward's nephew, who met with the King a month after his uncle's death in 1933.

Gavrilo Princip is paraded by his Austrian captors after assassinating Archduke Franz Ferdinand in Sarajevo
Loyal citizens came out in their thousands, lining the route into the city centre that was to be used for a rare official visit by a top member of the Habsburg royal house, Archduke Franz Ferdinand, second only in imperial protocol to the venerable, mutton-chopped emperor himself, Franz Joseph. Witnesses remember the morning sun being fierce as the crowds gathered, eight deep in places, many of them waving the yellow imperial standard of Austria-Hungary with its double-headed black eagle, some shouting ''Long Live the Archduke'' as the Gräf & Stift limousine drove sedately by. An imperial 21-gun salute, from the fortress high in the hills that ring Sarajevo, sent out puffs of smoke, vivid white against the blue summer sky.
But the crowd was seeded with six would-be assassins united in their loathing of Austria-Hungary. By the time the sun set, what happened in Sarajevo would plunge the world into the darkness of global war for the first time.
The details were well recorded: how the first attacker lost his nerve as the cortege passed, how the next attacker threw a grenade that struck the limousine but did not harm the Archduke, how the royal party nevertheless continued with the visit, how three would-be assassins melted away into the crowd and how one, a 19-year-old peasant, stood his ground.
Solzhenitsyn's role in the Soviet Union was simple. His writings, and in particular his book One Day in the Life of Ivan Denisovich, laid bare the nature of the Soviet regime. The book described a day in the life of a prisoner in a Soviet concentration camp, where the guilty and innocent alike were sent to have their lives squeezed out of them in endless and hopeless labor. It was a topic Solzhenitsyn knew well, having been a prisoner in such a camp following service in World War II.

In this July 27, 2010, file photo, a pair of archeologists begin dismantling the remains of an 18th century ship at the World Trade Center construction site in New York. Columbia University scientists say this week they have determined wood used in the ship's frame came from a Philadelphia-area forest in 1773, before the signing of the Declaration of Independence and the Revolutionary War.
Researchers said this week that a vessel unearthed four years ago at the World Trade Center site in Lower Manhattan was made from wood cut around the year 1773 - two years before the start of the war and three years before the signing of the Declaration of Independence.
Scientists at Columbia University's Lamont-Doherty Earth Observatory, writing in the July issue of the journal Tree Ring Research, said the white oak in the ship's frame came from a Philadelphia-area forest and matched the material used to build the city's Independence Hall.
They said they tentatively identified it as a Dutch-designed, Philadelphia-built sloop made to carry passengers and cargo over shallow, rocky water.
They said it sailed for 20 to 30 years before being weighed down and sunk to the bottom of the Hudson River as landfill to extend lower Manhattan.
