Archaeologist – a scientist who has been studying the past of mankind on the material sources, engaged in archaeology (archeo (archios) – and ancient Greek. lygos is the word, the doctrine).
Archaeology is a historical discipline, studying the material sources of historical past of mankind.
Material sources are tools of production and established with their help, material goods: buildings, weapons, jewelry, dishes, artwork — everything is a result of employment rights. Material sources, unlike writing, does not contain a direct narrative of historical events, and based on these historical findings are the result of scientific reconstruction. Considerable originality of material sources has necessitated the study of their experts-archaeologists, who excavate archaeological sites, investigate and publish findings and results of the excavations, restore that data on the historical past of mankind. A special value of archaeology is to study the eras when there was more writing in General, or the history of those peoples, whose writing was not in later historic times. Continue reading
In the archaeological Museum of Tigranakert in Nagorno Karabakh opened the exhibition of artifacts discovered during the excavation of a barrow near the village of nor Haykajour Markerscase district.
The exhibition features more than 30 exhibits, Dating from the ninth-eighth centuries BC: ceramic vessels, jewelry, bronze parts of a belt, gold jewelry in the form of animals, detail of the tomb, the iron weapon, the wooden parts of the staff, the correspondent of the “Caucasian knot”.
Part of the findings is being reviewed in Armenia, because the exact numbers will be known after all laboratory examinations, told the correspondent of “Caucasian knot” in the Department of tourism and historical environment protection of the Ministry of economy of Nagorno-Karabakh.
For excavations to State service of protection of the historic environment has invited archaeologists from Nagorno-Karabakh and Armenia.

The research team of paleontologists of the Berlin Museum of natural history, brown University and new York University Oswego showed that the unique regenerative ability of modern salamanders, most likely, was a feature of ancient four-legged vertebrates, lost in the course of evolution.
Salamanders have the amazing ability to restore damaged or lost limbs and internal organs. The controlling feature high regenerative mechanisms are the center of attention of a large number of biologists. They do not lose hope once to apply the received knowledge in the field of medicine.
However, regeneration is not the only thing that interests the scientific community. So, salamanders develop their hind legs in the embryo that distinguishes it from all other four-legged creatures.
“Their fingers are formed in reverse order compared to other four-legged vertebrates. It remains a mystery for over a hundred years. We are very interested in, as a way of evolutionary development of the limbs is associated with high regenerative capabilities,” says Dr. Trubish Nadia (Nadia Fröbisch), the author of the study.
