A new analysis of the world-famous fossils, whose age is estimated to 3,46 billion years finally helped to resolve the longstanding disputes of scientists. The study was conducted by experts from the University of Western Australia.
In 1993, American scientist bill SCHOPF (Bill Schopf) described a tiny sample (about 0.5-20 micrometers in diameter): these were carbon-rich silicon fiber breed age and 3.46 million years, found in the Pilbara region of Western Australia. He suggested that rocks were formed by some forms of bacteria, including cyanobacteria.
This sample, called the Apex chert microfossils, soon entered the textbooks and other popular scientific literature as the earliest evidence of life on Earth. However, its unusual color and complexity has caused scientists some questions.
The first doubts arose in 2002 when a team under the leadership of Martin Brasier (Martin Brasier) from Oxford University (which, incidentally, was a sponsor and the current study) found that breed was not part of the simple block of sedimentary rocks, but was extracted from hydrothermal rocks formed from the flow of underground fluids, for a long time exposed to high temperatures.

Archaeologists exploring the world in search of the mysterious artifacts of the past. They gently blow away the dust of centuries with a variety of artifacts, and among the usual debris of history meticulous archaeologist will be able to find rare powerful relics.
Artifacts provide invaluable information about the history of the world, and some collectors are willing to part for them with their money. After finding the archaeologist is duly described in its magazine, it is possible for the Bank to sell to a dealer or Museum keepers.
Archaeology belongs to the category of secondary professions. This means that to possess the ability to research and gather the shards of the past and everyone can, regardless of what other professions they have mastered.
The work of the archaeologist begins with a study of maps of Azeroth in search of a suitable location for excavation. After this, he goes there with their research tools designed to help the seeker to find out the whereabouts of the most valuable historical fragments. In various places you can find different types of artifacts and obtain different rewards. Continue reading
In southern Africa found the remains of 15 partially preserved skeletons related to the modern human species that lived on our planet about 3 million years ago.
In an article published in the journal Elife, it is emphasized that this discovery radically changes representation about ancient mammals and is one of the most important in recent times.
Professor Lee Berger, who led the expedition, in an interview with bi-Bi-si has declared, that anything similar has never seen and even imagined that such discovery is possible at all. He also said that, in his opinion, these creatures were one of the first in the chain leading to modern man.
“Finding the first bones, we hoped to detect at least the remains of one being, and as a result found a few skeletons. By the end of three weeks the expedition emerged that found the largest burial place of the remains of relatives of human rights in the history of Africa,” says the Professor.
Who is he – Homo naledi?
15 skeletons, the bones of which are perfectly preserved, were found in an underground cave.
Representatives of the new species was named Homo naledi. Scientists have attributed them to the genus Homo, which includes modern man, and believe that these creatures had the ability to some sort of ritual behavior. Continue reading
In one of the suburbs of Kaliningrad treasure hunters found the wreckage of the Soviet IL-2, deceased in 1945 in the battles for Koenigsberg. Before the excavations had spent a lot of time obtaining permits and clearing areas. As the plane was with bombs. But while these questions were being solved, “black diggers” don’t waste time.
The roads to this place are almost there, to the fallen of Antiques IL-2 had to go two kilometers. On either side of the path – eroded trenches and pits from the dugouts. A 45-m here the Soviet troops had closed the ring of encirclement. But German troops kept the defense. Not to give to break the tanks of the enemy against them used the IL-2 attack aircraft. This plane crashed right in the centre of the German fortifications.
Yuri Rjabcev, special correspondent the Ministry of internal Affairs of the Russian Federation in Kaliningrad: “our arrival here have been grave diggers, what they did, clearly visible behind us. Dug a pit, the groundwater was not allowed to reach the engine and branchline”.
This plane is found searchers of Antiques a few years ago, but especially about the finding did not apply. Wrote a letter to the Western Department of internal Affairs on transport, announced in the headquarters of the Baltic fleet. And patiently waiting for the clearance. Continue reading
The people settled in South America in a single migration wave, soon after their ancestors first came from Siberia to the Western hemisphere.
Settlement in South America was discussed in a paper presented at the annual conference of the society of American archaeology in San Francisco. The work is based on DNA extracted from the remains of five ancient people who lived in the Peruvian Andes.
The most ancient Parking in South America – Monte Verde – has an age of about 14,6 thousand years. This date suggests that people quickly crossed two continents, through one or two thousand years after Beringovuy passed under the bridge. It is possible that the ancestors of the Americans were moving along the Pacific coast.
But some scientists believe that was the second wave of migration. They note that the elongated, narrow skull, which were the inhabitants of South America about five thousand years ago, too different from the round heads later the natives and modern native Americans. According to some researchers, the differences suggest that the waves of migration were more. Continue reading
