South Africa, Sep 12 (Canadian-Media): Scientists discovered a 73,000 years old sketch in a South African cave was believed to be the world's oldest known drawing by the humans, said the researchers in a report released Wednesday by the journal Nature, media reports said.
This sketch was created with a sharpened flake of ochre, a pigment widely used in the ancient world, said Christopher Henshilwood of the University of Bergen in Norway.
The sketch looking a bit like a hashtag is a proof that early humans in southern Africa could produce designs on various surfaces with different techniques.
The sketch has six red lines crossed by three other curved lines appears on a tiny flake of mineral crust and is believed to be part of a larger drawing, said the researchers, because lines reaching the edge are cut off abruptly there.

The hashtag design was produced widely over the past 100,000 years in rock art and paintings proving that the sketch is probably not just a collection of random scratchings.
Similar patterns are engraved in other artifacts from the cave, Henshilwood said and added,
"It almost certainly had some meaning to the maker, and probably formed a part of the common symbolic system understood by other people in this group," Henshilwood said.
The finding gives evidence that early humans could store information outside the brain and supports the argument that early members of our species behaved essentially like us before they left Africa for Europe and Asia, he said.
Silvia Bello, a researcher at the Natural History Museum in London who didn't participate in the study, called the finding important.
"It further shows how rich and complex human behaviour already was 73,000 years ago," she said in an email.

Mexico, U.S., Jul 16 (Canadian-Media): Mexico was struck with a 7.1-magnitude earthquake last September which opened a 13th century Aztec pyramid and revealed an even older temple within, media reports said.
While surveying the damage caused to the Teopanzolco pyramid, found 70 kilometres south of Mexico City, the archeologists were able to discover the ruins of the temple using radar technology.
According to archeologist Barbara Konieczna, the pyramid was heavily damaged in the earthquake, which flattened Mexico City and resulted in the deaths of more than 200 people.
It caused parts of the pyramid to sink and lean in a different direction resulting in a rearrangement of the core of its structure
"In spite of what the earthquake meant, it is necessary to be thankful that for this natural phenomenon appeared this important structure that changes the dating of the archaeological site,” said Konieczna in a news release from Mexico’s National Institute of Anthropology and History.
The temple dates back to between the years 1150 and 1200, according to the institute and is thought to be more than 800 years old.
Inside the temple, archeologists found an incense burner and ceramic shards.
Konieczna said that however strange it was, it was not unusual for the Tlahuica people and other Aztec groups to build over pre-existing structures, .
There seemed a possibility of the remains of a second temple nestled within the pyramid.
“Possibly, on the right side are the remains of another temple dedicated to Huitzilopochtli,” Konieczna said.
While continuing to examine the discovery, archeologists will also focus on restoring the pyramid’s main structure.

#Egypt'sAntiquitiesMinistry, #Giza'swesternnecropolis, #pyramids,
Toronto, Feb 4 (Canadian-Media): Egypt's Antiquities Ministry announced the discovery Saturday of the discovery of a 4,400-year-old tomb in a wider area of Giza's western necropolis, which is known to be home to tombs from the Old Kingdom near the pyramids outside Cairo, media reports said.
The tomb, according to official reports wss made of mud brick and included wall paintings and was in good condition depicting Hetpet -- a high high-ranking official thought to be close to ancient Egyptian royals during the 5th Dynasty of ancient Egypt -- observing different hunting and fishing scenes.
Other scenes also reportedly depicted a monkey — commonly kept as domestic animals in pharaonic times — reaping fruit and another dancing before an orchestra.
Similar scenes, according to the ministry's statement, were reported to have been found in other tombs belonging to the later 12th dynasty,
Mostafa al-Waziri, secretary-general of the Supreme Council of Antiquities who led the mission, believed there was still more to be found in Giza's western necropolis, which is home to the tombs of top officials of Egypt's Old Kingdom and said excavation work was underway for the other tomb.
"This is a very promising area. We expect to find more," Al-Waziri reported to have told reporters at the site. "We have removed between 250-300 cubic meters of layers of earth to find the tomb."
"What we see above the earth's surface in Egypt doesn't exceed 40 percent of what the core holds," he added.

Toronto, Dec 18 (Canadian-Media): A study published in the journal Earth and Planetary Science Letters challenges the the assumption that Mars formed near Earth from the same building blocks, media reports said.
Mars was reportedly formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current position, before migrating to its present location.
Moreover the two planets have different compositions. Mars contains different, lighter, silicates than Earth, more similar to those found in meteorites.
Researchers from Japan, the United States and the United Kingdom ran simulations to gain insights into the Red Planet's movement within the solar system to explain why the elements and isotopes on Mars differ widely from those on Earth.
In these simulations, the researchers gleaned additional insight into Mars' formation. A small percentage of the simulations suggested that Mars formed much farther from the sun than it is now and that Jupiter's gravitational pull pushed Mars into its current position.
