Scientists from Britain and Canada found in Western Canada remains of fish, which is probably the ancestor of all modern and extinct inhabitants of the seas and freshwater bodies. Description of fossils and assumptions about its significance to the history of the evolution of life on Earth published in an article in the journal Nature .
Jean-Bernard Caron of the University of Toronto and his colleague Simon Morris from Cambridge University has for decades carried out excavations in South-Eastern British Columbia (province in Western Canada), where lie the rocks of the so-called Burgess shale. They were formed at the bottom of the primary ocean of the Earth 509-505 million years ago, in the Cambrian era, during which he conceived and began to develop multicellular life.
The Burgess shales and their Chinese counterpart, Maotianshan are considered a kind of El Dorado of modern paleontology — only in strata preserved imprints of cartilage, bones and soft tissues of the first vertebrates. Despite the richness of these shales, scientists know almost nothing about how it looked the first fish as they emerged and evolved in the first era after the Cambrian explosion.
Caroni Morris found, apparently, the final answer to these questions by studying the fossilized remains of the ancient inhabitants of the oceans found in the so-called marble Canyon — previously unknown to scientists parts of the Burgess shale, which is open by the authors in 2020 in the national Park of Kootenay. In just two weeks of excavation in the canyon they found hundreds of fossils of large marine animals, including a creature that scientists have ranked as the mind Metaspriggina walcotti.
This is not a new kind: the first fossils of Metaspriggina walcotti had been discovered on the territory of “big” Burgess two years ago. The remains are preserved so poorly that their discoverers could not recover the General features of his appearance, or even to understand whether their owner vertebrates. The Caron and Maurice managed to find over a hundred prints Metaspriggina walcotti shales in Marble Canyon, many of which are preserved so well that they can see the smallest details of the structures of the eye, the muscles and other soft tissues.

Aegean civilization one of the ancient civilizations. It has evolved over the two millennia (3000 to 1200 years BC). The territory, which it occupied: the Aegean sea and its Islands, the Cyclades, the Peloponnese Peninsula, the Western coast of Asia Minor and the Eastern Mediterranean. The center of the Aegean culture is the island of Crete.
The first successful archeological excavations date back to 1876-the year in Mycenae and 1899-the year in Crete. Peak archaeological excavations clung to the NINETEENTH century. Then it was excavated several large cities: Poliochne (Lemnos island), Phylakopi (Milos island), Troy, Micena. In Poliochne was investigated wall height of 5 m; in Three of the Royal residence; in Crete the palaces of Knossos, Phaistos and Mallia; a in Mycenae Acropolis.
The most important discoveries can be called the conclusion of the English archaeologist Arthur Evans in the early twentieth century. After their amazing discoveries in Crete, he first compared them with the ancient Greek literature, Egyptian and Asian texts, and came to the conclusion that the culture of Crete to be associated with the cultures of Egypt and other countries of the ancient East. After that, he presented his version of the periodization of Aegean civilization and called it Minoan. Its essence is to divide it into three main periods, and each period of three subperiod. The study of the Aegean culture at the moment is complicated,as the script is still not deciphered.
– The early Minoan period (3000 – 2300 years BC). It lasted almost 8 centuries, and during this time the island of Crete didn’t know enemy attacks. This allowed well-to develop the agrarian sector (the island at that time was very fertile), navigation (the tracks lead to Egypt). At the same time started the development of metal, namely copper, which in turn gives impetus to the development of the craft. Continue reading
Not every city is fortunate enough to preserve the original appearance. In difficult times of war and conquest many cities were destroyed and then rebuilt, so only a few buildings managed to “survive” until our times. Remains of a magnificent city, which can rightfully wear the proud title of “the oldest city in the world”.
The mention of the first settlements on the site of modern Jericho are 9000 BC, After three millennia, the city actively began to rebuild and by the end of the 3rd and 2nd Millennium reached its peak. Several times he has been destroyed, one of which was mentioned in the Bible.
It was a magnificent city, in which houses were built of brick and stone. Archaeologists discovered ruins of an ancient synagogue, Dating back to I century BC, a magnificent winter palaces with baths, swimming pools and ornate halls. Near Jericho the mountain of Karantal, which, according to legend, Jesus was forty days tempted of the devil. Now in that place there is the magnificent rock-hewn monastery of Temptation.
One of the oldest city is Damascus, the first mention of which appeared in the middle of the 2nd Millennium BC. Due to the fact that in ancient times Damascus was under the rule of the Egyptians, Israelites, Assyrians, Persians and even Alexander the great, this ancient gurudwaras in the culture of these peoples.
He became known for his Damascus steel, which was popular in medieval Europe. Today you can see the ruins of the ancient gates of the fortress protecting the city from invasions, the Catholic Church, temples, mosques, the old houses that represent the most important monuments of Damascus culture and history.
